Untitled[edit]
There are basically three interior drain systems. One, and the oldest, is a true French drain which is commonly a 4" perforated pipe below the floor and parallel to the bottom wall structure which may be a stone wall, a poured concrete wall and or a footing for that wall. The second and maybe most commonly installed is a quicker but less effective system that sits on the footing. But 50% of homes do not have footings, so that pipe is still installed above the bottom of the structure. Finally, there are on the floor systems which are the easiest to install. The action of the water, which is from a FALSE water table, exerts hydraulic pressure on the interior floor/wall joint. The above three act in very importantly different ways and use physical laws to divert this water to prevent it from entering through the floor wall joint or through floor cracks and therefrom to the floor surface. The French drain diverts the water at the point of greatest pressure, the bottom of the structure. The shallower second method requires water to actually continue to enter the sub-floor area and to use the floor as a component in the hydraulic pressure effect. Therefore, water will continue to have an adverse effect on the floor and if cracks exist, enter to the floor that way as well. The claim that water enters primarily through a supposed joint at the wall and footing is false and not physically possible. The third method is a tracking system that sits on the surface of the floor and diverts the water as it continues to enter from the floor wall joint.
Article status?[edit]
I have really streamlined and tightened this article up. There is a reference that is no longer in the body of the article, but otherwise, I think this article is in solid shape.
