Basement Drainage Options - Basement Tanking simplified means keeping water out of your basement or below the ground structure. Your cellar doesn't need to be fully underground either to possess potential issues with water. Even sloping sites where your cellar is built into a hill side or has only one wall with ground up against it means that you could have a problem with water later on. So what are your Basement Tanking Alternatives. ?
Simplified there are just two ways of tanking a cellar. The first method is to utilize an external system. These systems when applied to the exterior of the structure form a barrier to prevent water penetrating the building. To utilize this strategy you can only do so when constructing a new cellar. (for all the obvious reasons). Successful external cellar tanking means forming a watertight membrane barrier both underneath the concrete slab as well as the vertical surfaces effectively making a watertight tank around your cellar.
It has benefits of maintaining the construction dry and using the ability of any water present 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 best and the land drain intercepts water and diverts it from the applied membrane and the structure.
Please be aware that although it may appear easy in principle that the detailing and site requirements can be a substantial problem in receiving these systems placed in correctly. It just takes one mistake in workmanship in employing external cellar tanking products and you could have a really waterproofing catastrophe. Wet, muddy and also very cold states may not suit the manufacturer's recommendations when employing this sort of system be very conscious that unless you follow their guidelines you may have no recourse if things go wrong.
