Should I Waterproof My Basement Walls - Your basement doesn't need to be completely underground either to have possible issues with water. Even sloping sites where your basement is built into a mountain side or has just 1 wall with earth up against it means that you could have a problem with water later on. So what are your Basement Tanking Options. ?
Simplified there are just two means of tanking a basement. The first technique is to use an outside program. These systems when applied to the outside of the structure form a barrier to stop water entering the construction. To use this approach you can only do so when building a new basement. The area to pay close attention to is the wall floor intersection. Successful outside basement tanking means forming a watertight membrane barrier both underneath the cement slab as well as the vertical surfaces efficiently making a watertight tank around your basement.
This has benefits of maintaining the building dry and employing the ability of any water current to push the membrane on the structure. Many designers use a property drain at adjacent externally to the wall floor intersection footing. This is the area where water pressure is at its greatest and the land drain intercepts water and diverts it away from the applied membrane and also the structure. There are a variety of unique products available to individuals utilizing this option when basement tanking including, paint or spray applied liquid membranes, torch on/heat welded membranes, bonded sheet drains, clay matting membranes etc..
Please be aware that although it may appear easy in principle that the detailing and site requirements can be a significant problem in getting these systems put in correctly. It just takes one error in workmanship in applying external basement tanking products and you may have a very waterproofing catastrophe. Wet, muddy and also very cold states may not match the manufacturer's recommendations when applying this sort of system be very aware that unless you follow their guidelines that you may not have any recourse if things go wrong.
