REpairing Retaining Walls, Arches, Bridges and Homes| North and South Islands | New Zealand

Our REpair department serves to rectify common issues with ageing bridge & retaining wall structures, bridge expansion joints and deck seals, buried arches, culverts and pipes. And as the worlds’ infrastructure ages, there is an integral need for a company that can deal with the complexities surrounding remedial works on retaining structures, bridges, tunnels & water services on all scales, large or small.

REpair of ageing civil and residential structures is something that separates us from other contractors.

The difference between the traditional geo-contractor and the operational capacity of retained earth is that we operate in both small-scale residential and large scale commercial. We are content in bringing superior levels of service across the board.

A bridge is just as important as your home. Therefore, we apply the same level of expertise across all projects — regardless of the size of the job or contract value.

We remedy critical failures such as overturning or sliding, rupture, cyclic fatigue, mechanical disturbance, water-ingress issues such as concrete cancer & scour (soil loss through weather/ water), subsidence, concrete panel structural or connection-point failure, general cleaning and maintenance including anti-graffiti treatments, acid sulfate reactivity, sealing and general surface treatments.
