Hydro-Gel Injection for Leaking Polystyrene Block Retaining Walls


EQR – Residential, Christchurch

Leaking polystyrene block walls pose a problem for their repair, especially if they cannot be easy excavated or if excavation could cause further damage to the structure. In this case the existing membrane has become damaged during the Canterbury earthquakes. Concrete Solutions® approach to provide a successfully conclusion is to inject a new membrane behind the structure using MC-Injekt GL-95 which is a flexible hydro structure acrylic gel.
