Injection System

FOR EVERY PROBLEM THE RIGHT SOLUTION

TUNNELS - The concrete roof of the rail link tunnel passing under the Cooks River experienced 'map' cracking.  The permanent sealing of the cracks was achieved quickly and economically through Hydrogel injection.

 

LIFT PITS - The combination of waterproofing membrane failure and poorly vibrated concrete resulting in a continually leaking lift pit.   The cracks and voids in the structure made the waterproofing additive to the concrete ineffective.  The problem was solved through Hydrogel injection.

BASEMENT CAR PARKS - Insufficient waterprooing design and poor building practice created the situation where the basement constructed below the water table leaked when the dewatering pumps were removed.  The active leaks were sealed by a combination of Polyurethane and Hydrogel injection.
