Hydrostatic Pressure Basement Slab - Basement Tanking simplified means keeping water from your basement or beneath the ground construction. Your basement does not need to be completely underground either to have potential problems with water. Even sloping sites where your basement is built into a mountain side or has only 1 wall with earth up against it means that you might have a problem with water later on. What exactly are your Basement Tanking Options. ?

Simplified there are just two means of tanking a basement. The first method is to utilize an external system. These systems when applied to the outside of the construction form a barrier to prevent water entering the construction. To utilize this approach you can only do this when constructing a new basement. Successful external basement tanking means forming a watertight membrane barrier both under the concrete slab as well as the vertical surfaces effectively creating a watertight tank around your basement.

It has benefits of maintaining the construction dry and employing the power of any water current to push the membrane onto the structure. Many designers use a land drain at adjacent externally to the wall floor intersection footing. This is where water pressure is at its best and the land drain intercepts water and diverts it in the applied membrane along with also the construction. There are a variety of different products available to people using this option when basement tanking such as, paint on or spray applied liquid membranes, torch on/heat welded membranes, bonded sheet drains, clay matting membranes etc..

Please be aware that although it may seem easy in principle the detailing and site requirements can be a substantial problem in getting these systems placed in correctly. It just takes one mistake in workmanship in applying external basement tanking goods and you could have a very waterproofing catastrophe. Wet, muddy and also very cold conditions may not match the manufacturer's recommendations when applying this sort of system be very aware that unless you follow their guidelines you may have no recourse if things go wrong.
