Crack injection is commonly used in residential and commercial applications primarily because it is far less expensive than excavating a foundation and waterproofing the exterior foundation wall, floor slab, carpark, tunnel, bridge, pit, channel, drain. There is also no need to remove tiles and other finishes from the surface in order to fix leaks. Crack injection is the most reliable leaking crack repair system when done properly.


Used to repair leaking concrete joints / cracks in - concrete carparks, tunnels, bridges, water treatment plants, pits, dams, tanks, apartment buildings, undergound cellars, retaining walls, factories, tilt slab concrete constructed buildings, and more.  



Commercial Business Application BannerCONCRETE CRACK - Crack

Injection Leak Sealant - was used to repair a cooling tank at the Geelong Galvanising Plant. The process was carried out on all visible cracks from the inside of the tank reservoir, as you can see from our photos. The cooling tank is used after the steel is removed from the furnace to cool the steel once galvanised. The water temperature inside the tank can be up to 90 oC once steel has been cooled.
