MaxBuild is a specialist concrete repair contractor operating throughout the North Island of NZ and throughout Fiji. From our Auckland offices and depot and we repair concrete and masonry on bridges, wharfs, culverts and commercial buildings. Although most of our concrete repair work is on existing structures we also repair defects during new construction.

Concrete Repair

Concrete Repair – Spalled concrete

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.

 

Concrete Repair

Large volume concrete repairs – Wet spraying and gunite

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.

Concrete Repair

Crack Concrete Repair

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.
