Abstract (en)
[origin: WO8304276A1] To lower underground waters in the area of foundation elements, such as foundation piles, a pervious layer of filtering concrete (1), particularly spongy concrete, is arranged under the normal concrete portion (7). Thereby, water is sucked through a conduit (6) traversing the foundation element and forming in the area of the filtrating concrete layer (1) a pervious filter-pipe (4). The filtering concrete layer (1) is preferably reinforced by a metal trussing (2). After lowering the surface of the underground sheet, the filtering concrete (1) is pressure injected with a hardening material, so that the lower end of the foundation element will be reinforced and will be capable of withstanding the pressure transmitted by the upper portion.
