    Reliable commercial waterproofing services on the Gold Coast

    Basement Waterproofing

    Basement waterproofing and drainage considerations are especially needed in cases where ground water is likely to build up in the soil, and raise the water level. This higher water level causes hydrostatic pressure to be exerted underneath basement floors and against basement walls.
    Hydrostatic pressure forces water in through the cracks in foundation walls, through openings caused by expansion and contraction of the footing-foundation wall joint and up through floor cracks. It can cause major structural damage to foundation walls and is likely to contribute to mould, decay, and other moisture related problems.

    Chemical Pressure Grouting

    Chemical pressure grouting is an injection system that fills and seals cracks and voids within a concrete slab. Using an impermeable polymer grout (Polyurethane) pressure grouting will seal the crack/joint from air and water, the main cause of concrete spalling. Polyurethanes are usually quite flexible and will accommodate thermal and structural movement. Chemical pressure grouting is used in all concrete structures including:

    • Weeping hairline cracks
    • Joints: cold/expansion/pipe penetrations
    • Lift shaft walls and floors
    • Rooftop slab structures: car parks / podiums etc.
    • Soffit crack injection: epoxy and PU grouts
