Small Homes With Finished Basements - Basement Tanking simplified means keeping water from your basement or beneath the ground construction. Your basement doesn't need to be completely underground either to have possible problems with water. Even sloping sites where your basement is built into a hill side or has only one wall with earth up against it means that you might have a problem with water later on. So what are your Basement Tanking Options. ?
Simplified you will find two means of tanking a basement. The first method is to use an external system. These programs when applied to the outside of the construction form a barrier to prevent water penetrating the building. To use this approach you can only really do this when constructing a new basement. (for all the obvious reasons). The area to pay close attention to is the wall flooring intersection. Successful external basement tanking means forming a watertight membrane barrier both under the cement slab and up the vertical surfaces efficiently making a watertight tank around your basement.
It has advantages of keeping the construction dry and using the power of any water present to push the membrane onto the structure. Many manufacturers use a land drain at adjoining externally to the wall floor intersection footing. This is the area where water pressure is at its best and the land drain intercepts water and diverts it in the applied membrane and also the construction.
Please be aware that though it might seem easy in principle that the detailing and site conditions can be a substantial problem in getting these systems placed in properly. It just takes one mistake in workmanship in applying external basement tanking products and you could have a really waterproofing disaster. Wet, muddy and also very cold conditions might not suit the company's recommendations when applying this type of system be very aware that unless you follow their guidelines you might not have any recourse should things go wrong.
