Old Metal Basement Windows - Your cellar does not have to be fully underground either to have possible issues with water. Even sloping sites where your cellar is built into a mountain side or has only one wall with ground up against it means that you could have a problem with water in the future. So what are your Basement Tanking Alternatives. ?
Simplified you will find two ways of tanking a cellar. The first method is to utilize an outside system. These systems when applied to the outside of the structure form a barrier to prevent water entering the construction. To utilize this approach you can only do so when constructing a new cellar. (for the obvious reasons). Successful outside cellar tanking means forming a watertight membrane barrier both under the cement slab and up the perpendicular surfaces effectively creating a watertight tank around your cellar.
It has advantages of keeping the building dry and using the power of any water current to push the membrane on the structure. Many manufacturers use a property drain at adjacent externally to the wall floor intersection footing. This is where water pressure is at its greatest and the soil drain intercepts water and diverts it from the applied membrane along with the structure.
Please be aware that though it might appear simple in principle the detailing and site requirements can be a substantial problem in receiving these systems placed in correctly. It only takes one error in workmanship in applying external cellar tanking goods and you could have a very waterproofing disaster. Wet, muddy and also very cold conditions might not match the company's recommendations when applying this sort of system be very conscious that unless you follow their guidelines you might have no recourse if things go wrong.
