What exactly are your Basement Tanking Options. ?
Simplified there are two means of tanking a basement. The first technique is to utilize an external program. These systems when applied to the exterior of the construction form a barrier to prevent water penetrating the building. To utilize this approach you can only really do so when building a new basement. (for the obvious reasons). Successful external basement tanking means forming a waterproof membrane barrier both under the cement slab as well as the vertical surfaces effectively making a waterproof tank around your basement.
This has benefits of keeping the building dry and using the power of any water present to push the membrane on the structure. Many manufacturers use a land drain at adjoining externally to the wall floor junction footing. This is the area where water pressure is at its greatest and the soil drain intercepts water and diverts it from the applied membrane and the construction.

It just takes one error in workmanship in applying external basement tanking products and you may have a really waterproofing disaster. Wet, muddy and also very cold states may not match the manufacturer's recommendations when applying this type of system be conscious that unless you follow their guidelines that you may have no recourse if things go wrong.
