Basement Floor Insulation Products - Your basement does not have to be fully underground either to possess potential problems with water. Even sloping sites where your basement is built into a mountain side or has just 1 wall with earth up against it usually means that you could have a problem with water in the future. What exactly are your Basement Tanking Options. ?
Simplified there are just two ways of tanking a basement. 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 entering the construction. To use this strategy you can only do this when constructing a new basement. (for the obvious reasons). The area to pay close attention to is the wall floor junction. Successful outside basement tanking means forming a watertight membrane barrier both under the concrete slab and up the vertical surfaces efficiently making a watertight tank around your basement.
This has advantages of maintaining the construction dry and using the ability of any water current to push the membrane on the structure. Many designers use a land drain at adjacent externally to the wall floor junction footing. This is where water pressure is at its greatest and the land drain intercepts water and diverts it in the applied membrane along with the construction. There are an assortment of different products available to people using this choice when basement tanking including, paint or spray applied liquid membranes, torch on/heat welded membranes, bonded sheet membranes, clay matting membranes etc..
Please be aware that though it might seem simple in principle the detailing and site requirements can be a substantial problem in receiving these systems put in correctly. It only takes one mistake in workmanship in applying external basement tanking products and you may have a really waterproofing disaster. Wet, muddy and also very cold conditions might not suit the manufacturer's recommendations when applying this type of system be conscious that unless you follow their guidelines that you might not have any recourse if things go wrong.
