Wood Floor Over Concrete Basement - Your cellar does not need to be completely underground either to have potential problems with water. Even sloping sites where your cellar is built into a mountain side or has just 1 wall with earth up against it usually means that you might have a problem with water later on. So what are your Basement Tanking Alternatives. ?
Simplified there are just two means of tanking a cellar. The first technique is to use an external 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 so when constructing a new cellar. (for the obvious reasons). Successful external cellar tanking means forming a watertight membrane barrier equally underneath the concrete slab and up the perpendicular surfaces effectively creating a watertight tank around your cellar.
This 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 adjoining externally to the wall floor junction footing. This is the area 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 a variety of unique products available to people using this choice when cellar tanking including, paint on or spray applied liquid membranes, flashlight on/heat welded membranes, bonded sheet membranes, clay matting membranes etc..
Please be aware that though it may seem easy in principle the detailing and site conditions can be a significant problem in getting these systems put in properly. It just takes one mistake in workmanship in employing external cellar tanking goods and you may have a very waterproofing disaster. Wet, muddy and also very cold states may not match the company's recommendations when employing this sort of system be very aware that unless you follow their guidelines you may have no recourse if things go wrong.
