Mohan Roofing Services, one of Auckland’s longest serving waterproofing companies, conducts numerous repairs to concrete, both structural and remedial.

This work has included basic crack repair, panel patching, concrete cancer treatment and structural repairs.

At Mohan Roofing Services we first work out what is causing the problem, then we come back with a method of rectification for a long standing repair, rather than a quick fix. Our work is then detailed to offer the best possible result, not only in strength, but also cosmetically. In some instances the repair can be hidden so no one will ever know it was there.

All concrete repairers are trained by leading suppliers and updated with regular training as products are continually evolving.

Commonly referred to as '' Single Shot Urethane'' Grouts, these products are two pot mix resins which are unaffected by moisture. They can expand up to 30 times there size, making them ideal for tight spaces, and they set to form an impermeable barrier, which is strong, flexible and long lasting. Typically they're used in sea walls, man holes, filling voids, or soil stabilization. they're permeable fluids so unaffected by changing moisture water tables.

Hydrophilic Polyurethane is ideal for crack filling and leak prevention. it actively, seeks out moisture, absorbs up to 30 times its weight in fluids, expanding into tight cracks and creating a strong and durable seal. it retains a degree of flexibility making it ideal where movement or expansion and contraction might be expected ( as is the case with most crack repairs).
