Some of our commercial waterproofing services on the Gold Coast includes waterproofing and drainage considerations for underground car parks. Waterproofing is 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.
