Concrete Repair Company

The correct repair depends on what has failed, why the deterioration has occurred and what the concrete needs to do afterwards.
We provide concrete repair services across the UK for commercial, industrial and other concrete structures, including floors, slabs, walls, beams and columns.
Start With the Damage
The visible defect is the starting point.
You might have a crack running through a concrete floor. Pieces of concrete may be breaking away from a column. A warehouse joint might be deteriorating under forklift traffic.
These problems should not automatically receive the same repair.
We deal with concrete affected by:
Cracking
Spalling
Exposed reinforcement
Corrosion-related deterioration
Potholes
Damaged floor joints
Broken edges
Surface wear
Impact damage
Failed previous repairs
Understanding the defect helps determine what needs to happen next.
Concrete Crack Repair
Cracks can develop because of shrinkage, movement, loading and other mechanisms.
The important distinction is whether a crack is stable or whether movement is continuing.
Suitable cracks can be filled, sealed or injected using an appropriate repair system.
Where cracking could have structural significance, the cause and condition of the affected element should be assessed before the crack is simply filled.
Concrete Spalling Repair
Spalling occurs when sections of concrete separate and break away.
In reinforced concrete, one possible mechanism is corrosion of the embedded steel.
As corrosion develops, expansion around the reinforcement can place pressure on the surrounding concrete.
This can progress through:
reinforcement corrosion → cracking → delamination → spalling → exposed steel
A repair may therefore need to address both the damaged concrete and the condition of the reinforcement underneath it.

Repairing Concrete Around Exposed Reinforcement
Once reinforcing steel becomes exposed, its condition becomes part of the repair.
Deteriorated concrete can be removed to establish the extent of the affected area.
The exposed reinforcement can then be cleaned and assessed before the concrete section is reinstated.
Where corrosion has caused significant loss of reinforcement section, the structural implications need to be considered rather than simply covering the steel with new repair mortar.
Structural Concrete Repair
Beams, columns, slabs and structural walls require a different level of consideration from purely superficial concrete damage.
The repair may need to account for:
Remaining concrete section
Reinforcement condition
Loads
Extent of breakout
Temporary support
Required structural performance
Repairing a structural element is not simply a matter of recreating its original shape.
The completed repair needs to satisfy the requirements established for that member.
Concrete Floor Repair
Industrial concrete floors deteriorate differently from many structural elements because they interact directly with traffic.
Forklifts, pallet trucks, vehicles and machinery can repeatedly pass over the same areas.
Small defects can then become larger.
A damaged floor joint is a good example:
broken edge → wheel impact → further concrete loss → rougher crossing → increased impact
Floor repair can address the damaged area before deterioration spreads further into the surrounding concrete.
Warehouse and Factory Floor Repairs
Industrial buildings concentrate activity into defined routes and working areas.
Warehouses typically have repeated traffic between goods-in, storage, picking and dispatch.
Factories can combine vehicle movements with production equipment, machinery and workstations.
We repair concrete within areas including:
Forklift aisles
Production areas
Loading areas
Doorways
Workshops
Storage areas
Goods-in
Dispatch routes
The repair system should reflect how the repaired section will actually be used.

Concrete Joint Repair
Floor joints require particular attention because the joint may still need to perform a function after the damaged concrete has been repaired.
Often it is the concrete immediately alongside the joint — the arris — that deteriorates.
Repeated wheel crossings can break these edges down.
Repair can rebuild the damaged concrete while retaining the required joint arrangement.
Movement joints should not simply be rigidly filled without considering the movement they are intended to accommodate.
Pothole and Localised Concrete Repairs
A damaged section of concrete does not necessarily mean that a complete floor needs replacing.
Where deterioration is isolated, local repair can target the affected area.
Loose or fragmented material is removed to establish a suitable repair boundary.
The section can then be reinstated using a repair material appropriate for the depth, substrate and future use.
This approach can be particularly useful for individual potholes, impact damage and local areas of spalling.
When Local Repairs Are No Longer Enough
A floor containing three damaged areas presents a different problem from one containing thirty.
As defects become widespread, continually adding individual patches can become less practical.
The scope may progress from:
isolated damage → local repair
multiple defects → planned repair programme
widespread surface deterioration → resurfacing assessment
The amount of intervention should follow the condition of the concrete.
Concrete Resurfacing
Resurfacing can be considered where deterioration extends across a broader area but the existing concrete remains suitable to form part of the floor.
The surface is prepared and existing defects addressed before an appropriate resurfacing material is installed.
This can be relevant for floors affected by widespread wear, numerous previous patches or shallow surface deterioration.
Resurfacing does not automatically solve deeper movement or structural problems within the slab, so the underlying condition still needs to be understood.
Impact-Damaged Concrete
Concrete can also be damaged suddenly rather than through gradual deterioration.
Vehicle strikes can affect columns, walls and edges within industrial buildings and car parks.
Machinery and handling operations can damage concrete within factories and warehouses.
The repair requirement depends on how much material has been lost and whether the impact has affected reinforcement or a structural element.
A broken corner may need straightforward reinstatement.
Significant damage to a load-bearing column can require structural assessment before repair begins.
Failed Previous Concrete Repairs
An existing repair can provide useful information about the underlying problem.
If a patch has cracked, debonded or developed deterioration around its perimeter, simply placing another repair over it may repeat the same failure.
Instead, we consider:
What failed?
Was it the repair material?
Where did it fail?
Within the repair, at its interface or in the surrounding concrete?
Why did it fail?
Movement, continuing corrosion, poor substrate condition or another mechanism?
The replacement repair can then address the condition uncovered.

Repairing Concrete Starts Below the Surface
A repair material can only perform as intended when the area receiving it has been appropriately prepared.
This can involve removing loose, damaged or unsuitable concrete until a suitable repair substrate is established.
Where reinforcement is exposed, additional preparation is required.
The basic relationship is:
sound substrate → appropriate preparation → compatible repair material → completed repair
Skipping the condition of the existing concrete puts too much emphasis on the new product and too little on what it is being attached to.
Concrete Repair Mortars
Repair mortars can be used to reinstate sections of lost or removed concrete.
Different products are intended for different repair conditions.
Selection can depend on factors such as:
Repair depth
Orientation
Existing substrate
Structural requirement
Exposure
Application method
Required return to service
A mortar suitable for a small floor patch is not automatically the correct material for repairing a reinforced concrete beam.
Resin Concrete Repairs
Resin-based materials can also form part of concrete repair work.
Applications can include certain crack repairs, floor repairs and other specialist uses.
As with cementitious materials, the product should follow the repair requirement.
For example, a rigid resin installed into a crack that continues to move may not provide the required outcome.
The condition of the defect therefore comes before the choice of resin.
Concrete Injection
Injection provides a method of introducing repair material into suitable cracks, voids and other defects.
The objective can vary.
Some injection repairs are intended to transmit force across a crack.
Others may be intended to fill a defect while accommodating different behaviour or to control water ingress.
This means “concrete injection” describes a repair technique rather than one universal material or specification.
Commercial Concrete Repairs
Commercial properties can contain concrete within car parks, service areas, floors, ramps, loading areas and external structures.
The significance of deterioration varies considerably between these areas.
A damaged floor surface may primarily affect use and traffic.
Spalling on an overhead concrete element can introduce different risks and repair requirements.
We assess the affected element rather than treating all commercial concrete as one type of repair.
Industrial Concrete Repairs
Factories, warehouses and other industrial premises place additional demands on concrete.
Heavy traffic, machinery, repeated impacts and operational constraints can all influence repair work.
It may not be practical to close the complete building.
Where possible, repairs can be organised around working areas so that individual sections are isolated while other operations continue.
Material selection and sequencing can then account for the available working window.
Concrete Repairs in Car Parks
Car parks contain several different concrete elements within the same structure.
Repairs can be required to:
Decks
Ramps
Columns
Beams
Soffits
Edges
Parapets
The cause of deterioration can vary between areas.
A vehicle-damaged column, worn ramp and corrosion-related soffit spall should therefore be treated as separate repair conditions rather than receiving a standard car-park repair specification.
Repair or Replace?
Concrete deterioration does not automatically mean complete replacement.
Repair can preserve serviceable concrete while removing and reinstating only the damaged sections.
There are also situations where deterioration is too extensive for repeated local repairs to remain sensible.
The decision should consider:
extent of deterioration + condition of remaining concrete + required performance + repair practicality
This provides a more useful basis for deciding between local repair, wider rehabilitation and replacement.

BS EN 1504 and Concrete Repair
BS EN 1504 is the principal standard series covering products and systems used for the protection and repair of concrete structures.
Its different parts address areas including concrete repair products, structural bonding, injection, reinforcement anchoring, reinforcement corrosion protection and site application.
Not every part applies to every project.
The relevant repair principles and product requirements depend on the defect, deterioration mechanism and intended outcome of the work.
A Better Way to Specify Concrete Repair
Rather than starting with a product, start with the concrete.
1. Identify the defect
What is visibly wrong?
2. Establish the extent
How far does deterioration continue beyond what can be seen?
3. Consider the cause
Why has the concrete deteriorated?
4. Assess reinforcement where relevant
Has corrosion or section loss occurred?
5. Determine the repair objective
What needs to be restored or protected?
6. Select the repair method
Choose materials and techniques suited to that objective.
7. Prepare and repair
Remove unsuitable material, prepare the substrate and complete the specified reinstatement.
This creates a repair strategy around the actual condition of the concrete rather than forcing every defect into the same treatment.
