Basement Flooring Underlay - Basement Tanking simplified means keeping water out of your basement or below the ground construction. Your cellar does not have to be fully underground either to possess potential issues with water. Even sloping sites where your cellar is built into a hill side or has just one wall with ground up against it usually means that you could have a problem with water later on. What exactly are your Basement Tanking Alternatives. ?
Simplified you will find just two means of tanking a cellar. The first method is to use an outside system. These systems when applied to the exterior of the construction form a barrier to prevent water penetrating the building. To use this strategy you can only do so when constructing a new cellar. (for all the obvious reasons). Successful outside cellar tanking means forming a waterproof membrane barrier both underneath the cement slab as well as the vertical surfaces effectively creating a waterproof tank around your cellar.
It has advantages of keeping the construction dry and employing the ability of any water present to push the membrane onto the structure. Many manufacturers 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 away from the applied membrane and also the construction.
Please be aware that though it might appear simple in principle that the detailing and site conditions can be a substantial problem in getting these systems put in correctly. It just takes one mistake in workmanship in applying external cellar tanking products and you could have a really waterproofing catastrophe. Wet, muddy and also very cold conditions might not suit the company's recommendations when applying this sort of system be very aware that unless you follow their guidelines you might not have any recourse should things go wrong.
