Where concrete repair is required due to steel reinforcement corrosion, we undertake structural concrete repairs to the EN1504 standard. This involves saw cutting around the repair, cutting back behind the steel reinforcement, reinforcement priming and reinstating the repair with a compatible mortar. Reinstatement is usually by hand patching with a pre-bagged repair mortar for re-casting using a fluid micro-concrete. In most cases we use products certified to EN1504-3. Where spall repairs are large we can undertake structural concrete repair more cost effectively by spraying the mortar into place. We can wet spray the premixed mortars that we use for hand patching or we can use a dry spray gunite mix. These give better compaction and durability and are more cost effective over large areas. The method employed for concrete crack repair depends on whether the cracks are structural or non structural and whether they are static or dynamic. Concrete crack repair methods include epoxy resin injection, surface sealing and conversion of cracks to joints. For wet cracks we are able to inject foaming polyurethane resins that stop water flow through the cracked concrete. Concrete Repair
