CONCRETE REPAIR
& PROTECTION
We repair, strengthen and protect reinforced concrete across the North West and Midlands.
Concrete fails for a reason
Treat only the symptom and the problem comes back, often right next to the repair.
We find the cause, agree a specification that suits the structure and the budget, and deliver it to programme with the paperwork a main contractor needs.
WaltBray’s operatives bring hands-on concrete and waterproofing experience to every package.
Why contractors work with us
Survey-Led Scoping
We confirm the extent of defects before pricing, so the scope holds once work starts.
Programme aware delivery
We plan around other trades, access restrictions and phased handovers.
Paperwork in Order
RAMS before we start, progress photos during the works and a clear record at handover.
Concrete and water under one roof
Repairs and waterproofing from the same team, with no gap between the two packages.
What we do
Concrete
Deck Repair & Waterproofing
Car park decks, podium slabs, roof decks and balconies take constant exposure to water, de-icing salts and traffic. Once water gets through the surface, it attacks the reinforcement and leaks into the level below.
We survey the deck, repair the damaged concrete and seal it with a waterproof coating or membrane. Work can be phased so the building stays open while we're on site.

Deck Repairs
Drainage and Edge Detailing
Waterproof Coating
Concrete Deck Repairs
Ramp Repairs
Repair and protection
Before we repair, we find out why the concrete failed. Typical checks include visual and hammer surveys, cover meter readings to locate the reinforcement, and testing for carbonation and chloride levels.
We then break out the defective concrete, treat the reinforcement and rebuild the section with repair mortars or flowable concrete. A protective coating goes on last to slow further deterioration.
Includes
Breakout and reinstatement
Remedial work to new-build defects
Anti-carbonation treatments
Reinforcement treatment
Hand-applied and flowable repair mortars
Cracks in concrete, brickwork and stone let water in and weaken the structure. Injection fills the crack from the inside, giving a strong repair that barely shows on the surface.
We use epoxy resins where the aim is to bond the structure back together. Where the priority is stopping an active leak, we use flexible or expanding resins, and our waterproofing background puts us in a strong position for that work.
Resin bonding and injection
Includes
Structural crack injection
Void filling
Bonding hollow screeds and toppings
Reinforcement treatment
Water-stopping injection to basements and below-ground structures
Corrosion management
Repairing only the visible damage can leave the surrounding concrete at risk, and corrosion can even speed up next to a fresh repair. A corrosion management strategy protects the whole element, not just the patch.
We recommend an approach to match the life the client needs from the structure, from cost-led short-term repairs to long-term protection.
Includes
Embedded galvanic (sacrificial) anodes
Protective coatings
Advice at survey stage on where impressed current cathodic protection may be needed
Migrating corrosion inhibitors
Plant rooms, service areas and industrial floors need surfaces that resist water, chemicals and wear, and are easy to keep clean.
We apply resin and cementitious floor coatings, detailed around plinths, pipework supports and plant bases, with upstands to contain spills and leaks.
Protective coatings and floor systems
Includes
Plant room floor coatings
Hand-applied and flowable repair mortars
Remedial work to new-build defects
Anti-carbonation treatments
Reinforcement treatment
Systems from manufacturers contractors know
We use repair, injection and coating systems from Sika and Mapei installed in line with the manufacturer’s guidance.
Questions from contractors
-
Yes. We price against your scope and drawings, provide RAMS and work to your site rules and programme.
-
The North West and the Midlands. Larger projects elsewhere can be taken on by agreement.
-
Yes, and we recommend it. A survey confirms the true extent of the defects and keeps the scope from growing once work starts.
-
Yes. We phase the works and plan access with you so the site can keep operating.
-
Yes. Below-ground waterproofing, tanking and leak injection are core WaltBray services, so both can sit in one package.
