Grain silo installation and repair
We erect, dismantle, inspect, service and repair grain silos for flour mills, maize mills and agro-allied facilities in Nigeria, Ghana and across Africa.
Grain silos protect stock worth far more than the silo itself. A silo that is badly aligned, leaking or structurally weak puts that stock at risk, and a delayed installation holds up the whole facility.
Abba Grace handles the full life of a silo: assembling and erecting silo panels and roofs, installing ladders, platforms, conveyors and access systems, inspecting and repairing damaged sections, and dismantling silos that need to be moved or retired. We focus on proper alignment, structural stability and safe lifting throughout.
What we do
Grain silo installation and dismantling
We assemble, position, install and dismantle grain silos and their associated components for agricultural and industrial facilities. Our crews handle silo panels, roofs, structural supports, ladders, platforms, conveyors and access systems, with close attention to alignment, structural stability and safe lifting.
What's included
- Assembly and erection of silo panels and roofs
- Structural supports, ladders and platforms
- Conveyors and access systems
- Inspection during and after installation
- Dismantling with minimal disruption to operations
Grain silo servicing and repairs
We inspect, service and repair grain silos to restore structural integrity, reduce downtime and extend the service life of storage systems. This covers the silo body itself as well as supports, ladders, platforms, hatches and conveyors.
What's included
- Inspection of silo structures
- Repair of damaged panels and sealing of leaks
- Replacement of worn components
- Structural reinforcement
- Maintenance of hatches, ladders, platforms and conveyors
Signs your silo needs attention
Water is getting in
Leaks at panel joints, the roof or hatches let moisture reach stored grain. We seal leaks and repair damaged sections.
Panels are dented, cracked or corroded
Damaged panels weaken the structure. We repair or replace them and reinforce where needed.
Ladders, platforms or hatches are worn
Unsafe access is a risk to your staff. We repair and maintain access systems.

Frequently asked questions
What does grain silo installation involve?
Typically: assembling the silo panels and roof, positioning and erecting the structure, installing structural supports, ladders, platforms, conveyors and access systems, and inspecting the work. We pay close attention to alignment, structural stability and safe lifting at every stage.
Can a damaged silo be repaired instead of replaced?
Often, yes. Depending on the damage, panels can be repaired or replaced, leaks sealed and the structure reinforced. We inspect the silo first so you know what can be repaired.
Do you dismantle grain silos?
Yes. We dismantle silos and their associated components, planning the work to minimise disruption to your operations.
How much does silo installation or repair cost?
It depends on the silo size and number, the condition of the structure, the access equipment needed and the site location. Send us the details through our quote form and we'll quote for your job.
Where do you install and repair silos?
Across Nigeria and in other African countries. Our office is in Lagos, and our clients include mills in Lagos, Calabar, Kano and Ghana.

Industrial roofing, leak repairs and waterproofing
We install and repair roofs on factories, warehouses and commercial buildings, fix leaks, service gutters and drainage lines, and waterproof roofs with felt, mineral felt and liquid bitumen.
A leaking factory or warehouse roof damages stock, equipment and the building itself, and every rainy season makes it worse. Industrial roofs are large, high and often above running operations, so repairs need planning and proper fall protection.
Abba Grace installs and replaces roofing sheets, structural components and flashing, repairs leaking or deteriorated roofs, installs and maintains gutters and drainage lines, and applies felt, mineral felt and liquid bitumen waterproofing. Our crews work at height with full-body harnesses and planned safe work procedures.
What we do
Industrial roof installation and repairs
We install, maintain and repair roofs on factories, warehouses, commercial buildings and other industrial facilities. When a roof is damaged, leaking or deteriorated, we restore its protection and durability with proper planning, quality materials and strict attention to safety.
What's included
- Installation and replacement of roofing sheets
- Structural components and flashing
- Gutters and waterproofing systems
- Repair of leaking or deteriorated roofs
Roof gutters and drainage lines
We install, service and maintain roof gutters and drainage lines for industrial, commercial and residential buildings, so rainwater is collected and discharged properly and buildings are protected from water damage.
What's included

Delivered to the agreed specification
We complete the job within the agreed specifications and timeline, and leave a clean site.
Frequently asked questions
What is the difference between felt and liquid bitumen waterproofing?
Roofing felt and mineral felt are sheet materials laid, overlapped and sealed across a roof surface, which suits larger areas such as flat roofs. Liquid bitumen is applied as a coating, which makes it useful around joints, upstands, gutters and penetrations like ducts and pipes. We'll recommend the right option after seeing the roof. Our guide to industrial roof leaks explains the options in more detail.
Can you fix a leak without replacing the whole roof?
Often, yes. Many leaks come from specific damaged sheets, flashing, joints or gutters that can be repaired or replaced on their own. We inspect the roof first to find the cause.
Do you repair gutters and drainage lines too?
Yes. We install, clean, unblock, realign and repair gutters, downpipes and drainage lines on industrial, commercial and residential buildings.
How do you keep roof work safe?
Every job starts with a risk assessment. Crews working at height use full-body harnesses, and tools, harnesses and scaffolding are inspected before use. Read more on our health and safety page.
How much does industrial roof repair cost?
It depends on the roof size, the type and extent of damage, materials, access and location. Send photos and details through our quote form and we'll quote for your job.

Scaffolding and industrial painting
We erect and dismantle scaffolding for construction, maintenance and industrial projects, and prepare, prime and paint industrial facilities, buildings, equipment and structures.
Safe access comes first on any job at height. Scaffolding that is unstable, overloaded or poorly inspected puts every worker on it at risk, and a paint job is only as durable as the surface preparation beneath it.
Abba Grace erects and dismantles scaffolding on buildings, silos and plant for construction, maintenance, painting, fabrication and industrial projects, with attention to stability, access, load requirements, inspection and fall protection. Our painting service covers surface preparation, priming, painting, coating and finishing for industrial facilities, buildings, equipment and structures.

How to choose an industrial maintenance contractor
Seven questions to ask before you hire a contractor to work on your mill, silos, roofs or steel structures.
Work on a running mill, a grain silo or a factory roof affects production, stock and people's safety. Choosing a contractor on price alone can lead to delays, rework and incidents that cost far more than the original job. These questions will help you compare contractors properly.
1. Have they done this type of work before?
Industrial work is specialised. Ask what similar jobs they have completed, for which kinds of facilities, and ask to see photos of their work. A contractor who installs silos regularly will plan the job very differently from one who doesn't.
2. How do they manage safety?
Ask how they assess risks before starting, what protective equipment their crews use, and how they handle work at height, hot work and heavy lifting. A good contractor will answer clearly and won't treat safety as an afterthought.
3. Who will actually do the work?
Ask whether the job will be done by their own skilled crew, and who supervises on site. You want competent people for each task, such as welders, fitters and scaffolders, not general labour learning on your plant.
4. Do they understand what you need?
A good contractor asks questions before quoting: about your equipment, your timeline and how the work fits around production. If a quote arrives without anyone understanding your site, be cautious.
5. Is the scope clear in writing?
Make sure the quote says exactly what is included and what isn't, such as materials, scaffolding, parts, painting and waste removal. Clear scope prevents arguments and surprise extra costs later.
6. Can they handle related work?
Industrial jobs often overlap. A silo repair may need scaffolding, welding and painting; a roof repair may need gutter work. A contractor who covers related services can save you coordinating several companies.
7. Will they work to your specification and timeline?
Agree the specification and timeline up front, and ask how they will keep you updated during the job.
A quick comparison checklist
- Relevant experience and photos of similar work
- Clear answers on risk assessment, PPE and safe work procedures
- Their own competent crew and on-site supervision
- Questions about your needs before quoting
- A written scope that lists what's included
- An agreed specification and timeline

Roofing felt vs liquid bitumen: which waterproofing should you choose?
How felt, mineral felt and liquid bitumen work, where each one performs best, and why many roofs use both.
If your flat roof, roof deck or gutters are letting water in, the two waterproofing options you'll hear about most are roofing felt and liquid bitumen. Both are bitumen-based and both keep water out, but they are applied differently and suit different parts of a roof.
What is roofing felt?
Roofing felt is a waterproof sheet material supplied in rolls. It is laid across a prepared roof surface, overlapped at the edges and sealed, often by torching, so the sheets bond into one continuous waterproof layer.
What is mineral felt?
Mineral felt is roofing felt with a mineral-granule top surface. The granules give the top layer extra protection from weather and sunlight and a harder-wearing finish.
What is liquid bitumen?
Liquid bitumen is a waterproof coating applied as a liquid, by brush or roller. Because it flows into shape before it sets, it seals awkward details that sheets struggle with: joints, upstands, gutter linings and the areas around ducts, pipes and other roof penetrations.
Felt vs liquid bitumen at a glance
| Roofing felt / mineral felt | Liquid bitumen | |
|---|---|---|
| Form | Sheets in rolls | Liquid coating |
| How it's applied | Laid, overlapped and sealed, often torch-applied | Brushed or rolled on |
| Best for | Flat roofs and large open roof areas | Joints, upstands, gutters, ducts and pipes |
| Main strength | Continuous, even layer over a big area | Seals irregular shapes and small details |
| Surface preparation | Essential | Essential |
Why many roofs use both
On a typical industrial flat roof, felt or mineral felt covers the main surface, while liquid bitumen seals the details around ducts, pipes, upstands and gutters, where sheets are hardest to fit. Using each material where it works best gives a more reliable result than forcing one material to do everything.
How to choose for your roof
- Large flat area that leaks in several places? Felt or mineral felt is usually the better base layer.
- Leaks around ducts, pipes or joints? Liquid bitumen is designed for these details.
- Gutters leaking at joints? Liquid bitumen can line and seal them, but blocked or misaligned gutters need repairing first.
- Rusted or holed roofing sheets? No coating will fix a sheet that has failed. Damaged sheets need replacing first.
Preparation decides how long it lasts
Whichever material you choose, the surface underneath must be clean, dry and sound. Waterproofing applied over dirt, loose material or standing water won't bond properly, and the leak will return.

Planning a flour mill installation or relocation
What to plan for when you install a new mill or move an existing one, from site preparation to safe lifting and handover.
Start with a clear scope
Before any machine is lifted, agree exactly what is being installed or moved: which machines, platforms, elevators, conveyors, filter tanks and pipework are included, and what the finished layout should look like. A clear scope avoids surprises once work starts.
Prepare the site
- Confirm the building, floor and foundations are ready for the equipment.
- Make sure there is safe access for lifting equipment and deliveries.
- Plan where machines and parts will be stored before installation.
- Agree how the installation fits around any other work on site.
For a relocation: dismantle in a planned sequence
A mill that is being moved should be dismantled in a planned order, so that machines, platforms and components can be transported and reassembled without damage or confusion. Recording and labelling parts as they come apart makes reinstallation faster.
Lift and position safely
Mill machines, bucket elevators and steel platforms are heavy and awkward. Every lift should be planned, with suitable equipment and competent personnel. Heavy lifting is one of the highest-risk parts of the job, so it should never be rushed.
Install, assemble and align
The platforms and structures that carry the machines go up first, followed by the machines themselves, elevators, conveyors, pipework and filter tanks. Careful alignment at this stage matters for how smoothly the mill runs later.
Prepare for production
Once everything is installed, the plant is checked and supported through commissioning so that the line is ready for production. Plan for routine servicing from the start; it is easier than dealing with breakdowns later.
What affects the cost?
The cost of a mill installation or relocation depends on the plant's size and capacity, the number of machines, whether structures and platforms are included, lifting and transport needs, the distance between sites, and the timeline. Ask for a quote based on your actual scope.

Signs your grain silo needs repair
A practical guide for mill and storage managers: what to look for, what to check routinely, and when to bring in a professional.
Why silo maintenance matters
A grain silo is there to keep stored grain dry, secure and easy to handle. When a silo is damaged, the cost isn't only the repair. Moisture and contamination can spoil stored grain, and a structural problem can force you to empty the silo at the worst possible time. Catching problems early usually means a smaller, faster repair.
Seven signs your silo needs attention
1. Water is getting in
Water stains, damp grain near the walls or floor, or rust streaks running down from joints all suggest leaks. Common entry points are panel joints, the roof, hatches and the base of the silo.
2. Dented, buckled or cracked panels
Panels can be damaged by impacts, uneven loading or long-term stress. Any visible deformation should be inspected, because it can weaken the structure as a whole.
3. Corrosion
Surface rust can spread and thin the steel over time, particularly around bolts, joints and areas where water collects.
4. Loose or missing bolts and failed seals
Bolts and seals hold panels together and keep the silo weathertight. Loose bolts or cracked sealant are an early warning that leaks or movement may follow.
5. Damaged roof, hatches or vents
The roof takes the most weather. Damaged roof panels, hatches that don't close properly and blocked or broken vents all put stored grain at risk.
6. Worn ladders, platforms and access systems
Corroded ladders, loose handrails and damaged platforms are a safety risk for anyone who has to climb or inspect the silo.
7. Conveyors and connected equipment keep failing
Repeated problems with conveyors or other connected components can point to misalignment or wear that needs proper attention, not just quick fixes.
Routine checks you can do
- Walk around each silo regularly and look for dents, rust, stains and loose bolts.
- Check the roof, hatches and vents after heavy rain or storms.
- Inspect the silo when it is empty, before refilling, when walls and floor are easier to see.
- Check ladders, platforms and handrails before anyone uses them.
- Keep a simple record of what you find, so you can see whether problems are getting worse.
Only climb or enter a silo if your team is trained and equipped for work at height and confined spaces. If in doubt, leave the inspection to professionals.
When to call a professional
Call in a specialist if you see structural damage, leaks you can't trace, significant corrosion, or unsafe access systems, or if you're planning to move or remove a silo. A proper inspection tells you what can be repaired and what needs replacing.
Abba Grace inspects, services and repairs grain silos: repairing damaged panels, replacing worn components, reinforcing structures, sealing leaks and maintaining hatches, ladders, platforms and conveyors. Learn more about our grain silo installation and repair service, or request a quote.

Getting your grain silos ready for the rainy season
A practical before-and-after checklist to keep water out of stored grain when the rains arrive.
Moisture is one of the biggest threats to stored grain, and the rainy season is when hidden weak points in a silo show up. A few hours of inspection before the rains start can save a silo full of stock.
Before the rains: what to check
Roof and roof panels
- Look for damaged, dented or lifted roof panels.
- Check the seals and bolts where roof panels meet.
- Make sure the area around the roof's top opening is sound.
Hatches and vents
- Check that every hatch closes and seals properly.
- Clear vents of blockages, and make sure covers are intact.
Wall panels and joints
- Look for rust streaks or stains below joints, which often mark a past leak.
- Check for loose or missing bolts and cracked sealant.
- Note any dents or buckled panels for professional inspection.
The base
- Check the seal between the silo and its foundation.
- Make sure rainwater drains away from the base instead of pooling around it.
Gutters and drainage nearby
- Clear blocked gutters and drains on nearby buildings and around the silo area, so water doesn't collect against the silos.
Ladders, platforms and access
- Inspect ladders, handrails and platforms. Wet steel is slippery, and corroded access systems are dangerous in any season.
After the first heavy storm
Do a second walk-round after the first big storm of the season. Look for fresh water stains, damp grain near walls or the base, standing water around foundations and any wind damage to roof panels or hatches. Problems are much easier to trace while the signs are fresh.
Safety first
Roof and wall inspections involve work at height, and entering a silo is confined-space work. Only trained and properly equipped staff should do these checks. If you're unsure, leave them to professionals.
Found a problem?
Leaks, damaged panels and corrosion are much cheaper to fix before stored grain is affected. Read the seven signs your silo needs repair, see our grain silo installation and repair service, or request a quote.

Industrial roof leaks: causes and repair options
Why factory and warehouse roofs leak, how the main repair options compare, and how to choose the right one.
What causes industrial roof leaks?
Most leaks on factory and warehouse roofs come from a handful of causes. Finding the real source matters, because water often travels along the roof before it drips inside.
Corroded or damaged roofing sheets
Over time, sheets rust, crack or get damaged by foot traffic and impacts. Holes and thin spots let water straight through.
Failed flashing and joints
Flashing seals the edges and junctions of a roof. When it lifts, corrodes or loses its seal, water gets in at the joins.
Blocked or damaged gutters
When gutters and downpipes are blocked, misaligned or leaking, water backs up and overflows into the building or runs down walls.
Leaks around ducts, pipes and other penetrations
Every duct, exhaust pipe or vent that passes through a roof is a potential weak point if the seal around it fails.
Worn flat roof surfaces
Flat roofs and roof decks hold water longer, so cracked or aged waterproofing quickly turns into leaks.
Repair options compared
| Option | What it is | Best suited to |
|---|---|---|
| Sheet and flashing replacement | Removing damaged roofing sheets, structural components or flashing and fitting new ones. | Rusted, holed or broken sheets and failed flashing. |
| Felt and mineral felt | Waterproof sheet material laid, overlapped and sealed across a prepared surface. | Flat roofs and larger roof areas that need a continuous waterproof layer. |
| Liquid bitumen | A waterproof coating applied as a liquid. | Joints, upstands, gutters and the areas around ducts and pipes. |
| Gutter and drainage repair | Cleaning, unblocking, realigning, sealing or replacing gutters, downpipes and drainage lines. | Overflowing or leaking gutters and poor rainwater drainage. |
Many roofs need a combination: for example, replacing a few damaged sheets, sealing around ducts with liquid bitumen and clearing the gutters.
How to choose the right repair
- Find the source first. Paying to waterproof a whole roof won't help if the real problem is a blocked gutter.
- Consider the roof type. Sheet roofs and flat roof decks need different solutions.
- Think about the next rainy season. Durable repairs done properly once usually cost less than repeated patching.
- Plan for safety. Roof work is work at height. Make sure your contractor uses harnesses, inspected equipment and a risk assessment.
What affects the cost?
The price of an industrial roof repair depends on the size of the roof, the type and extent of the damage, the materials used, access and scaffolding needs, whether the building stays in operation during the work, and the location. A site inspection is the best way to get an accurate quote.

Scaffolding safety checklist for industrial sites
What to check before anyone steps onto a scaffold on a building, silo or plant site.
Scaffolding gives crews safe access to buildings, silos and plant, but only when it is erected, inspected and used properly. A collapsed scaffold or a fall from an unprotected edge can cause serious injuries. This checklist covers the basics to confirm before work starts.
Before anyone uses the scaffold
Was it erected by competent people?
Scaffolding should be put up, altered and taken down only by people with the right training and experience. Ask who erected it and who is responsible for it.
Has it been inspected?
The scaffold should be inspected after it is erected and before it is first used, and again after any alteration, damage or severe weather.
What to look at
- Base: standards sit on firm, level ground or base plates and sole boards, with nothing missing or sinking.
- Structure: standards are upright, bracing is in place and fittings are tight.
- Ties: the scaffold is tied to the building or structure where required, and ties have not been removed.
- Platforms: working platforms are fully boarded, with no gaps, broken boards or loose boards.
- Edge protection: guardrails and toe boards are fitted on every open edge where someone could fall or drop materials.
- Access: there is a safe way up, such as a secured ladder or stair, so nobody climbs the frame.
- Loads: materials on the platform are within what the scaffold was designed to carry, and are not stacked against guardrails.
- Surroundings: the area below is protected, and the scaffold is clear of overhead power lines and moving vehicles.
While work is going on
- Don't remove ties, braces, boards or guardrails to make work easier. Only competent scaffolders should alter the scaffold.
- Keep platforms tidy, so tools and offcuts don't become trip hazards or fall onto people below.
- Use harnesses where the job and the risk assessment require them.
- Stop work and report any damage, movement or missing parts straight away.
Scaffolding around silos and plant
Silos and industrial plant add extra challenges: curved surfaces, heights, nearby machinery and work that has to continue around production. Plan the scaffold with the job in mind, so welders, fabricators or painters have safe access to everything they need to reach.
Need scaffolding for your project?
Abba Grace erects and dismantles scaffolding for construction, maintenance, painting, fabrication and industrial projects on buildings, silos and plant, with attention to stability, access, load requirements, inspection and fall protection.

Steel structure corrosion: signs, causes and repair
How to spot corrosion on industrial steelwork early, and what an overhaul involves when it's needed.
Industrial plants rely on steel platforms, frames, galleries, supports and roof structures. Corrosion slowly eats away at that steel, and because it often starts in places nobody looks, it can go unnoticed until a structure is weakened.
Signs of corrosion to look for
- Rust staining and flaking paint, especially at joints, connections and the bottom of columns.
- Bubbling or blistering paint, which often hides corrosion spreading underneath.
- Scaling or layered rust, where the steel is visibly losing thickness.
- Holes or thin spots in plates, gutters or sheet sections.
- Corroded bolts and fixings, which can weaken connections even when the main members look sound.
What causes it?
Water that sits on the steel
Steel corrodes fastest where water collects and stays: flat ledges, joints, column bases and blocked gutters. Leaking roofs and gutters above a structure make this much worse.
Damaged protective coatings
Paint protects steel only while it is intact. Once a coating chips, cracks or wears through, the steel underneath starts to corrode.
The working environment
Humid air, coastal locations and industrial processes all speed up corrosion, which is why steel in some plants needs more frequent inspection than others.
Why it matters
As steel loses thickness, it loses strength. Corroded platforms, handrails and galleries become a safety risk for the people who use them, and corroded structural members can affect the whole structure. Repairing early is usually far less disruptive than replacing large sections later.
What a steel structure overhaul involves
Inspection
Assessing the condition of steel members and connections.
Repair and reinforcement
Repairing, replacing or reinforcing weakened members, with fabrication and welding as needed.
Surface preparation
Removing rust and failed coatings so new protection can bond.
Protective coating
Priming and painting to protect the steel going forward.
Preventing it from coming back
- Fix roof and gutter leaks that drip onto steelwork.
- Touch up damaged paint before corrosion takes hold.
- Inspect steelwork regularly, especially joints and column bases.
