A specially designed drain. The patented WaterGuard® perimeter drain system from Basement Systems UK is the solution to basement or cellar water problems. This high-strength, plastic drainage channel is designed to capture water that leaks through walls and floors and convey it to a sump pump for removal from the building. By providing an effective escape route for subterranean water (instead of trying to hold it back), hydrostatic pressure is reduced to minimal levels and water leakage problems are eliminated.
When water is coming into your basement through the floor it's a sure sign that your basement is being subjected to significant hydrostatic (water) pressure.
In other words, water is saturating the soil outside your foundation and exerting enough pressure to have it percolate up through the floor. But don't panic if your basement or cellar has this problem!
There are ways to waterproof a basement floor and they are based on how water gets into the basement.
Water can leak through a basement floor slab in three ways:
Through the crack between the slab and the basement walls. The concrete slab is poured separately from the walls, and it's usually not possible to totally seal the crack between these two structural elements. Instead, we recommend installing our patented WaterGuard® concealed drain at this juncture. The WaterGuard® system effectively captures water that leaks through basement walls and through the wall/floor joint. This water is conveyed to a sump pump so that it can be pumped out of the house.
Through cracks in the basement slab floor. If the basement or cellar slab floor has cracked in different places, the cause of these cracks should be determined. After taking corrective measures, a permanent repair can be made to close the crack and seal this leakage area.
Through the porous concrete of the slab. Concrete can form a water barrier, but it's also a porous material. When the soil is very wet, the concrete slab can absorb moisture from the soil like a sponge and release it into the basement or cellar area. This creates high moisture conditions in the basement even when there is no standing water from leaks.
In wet weather, water pressure builds up outside a house foundation. With water pressing constantly against foundation walls and the foundation floor, even small cracks are likely to become leakage points, leading to basement flooding. The solution to this problem is to provide water with an escape route so that hydrostatic pressure can be dramatically reduced. The WaterGuard® interior drain and sump pump system perform this function perfectly. Instead of forcing its way through cracks in basement walls or the basement floor, water follows the path of least resistance. It flows through perimeter drains, ending up in a sump pit where it can be pumped out of the basement.
