ABSTRACT:
A system and method for preventing the accumulation of water below and about a building and soil surrounding the building, the building having a foundation built on disturbed soil, which is in turn surrounded by undisturbed soil and the foundation extending to a depth. The system includes at least one trench section about the foundation, the trench being at least as deep as the disturbed soil about foundation and having sides and a bottom. At least one side of the trench being bounded by undisturbed soil. The trench section also includes a first end and a second end, the trench bottom having a slope between the first end and the second end, the second end terminating in a sump pit. An impermeable liner over the sides and bottom of the trench and extending into the sump pit. The impermeable liner is inserted into and held against the undisturbed soil that forms a side of the trench by a substantially rigid edging material, so that water filtering through the disturbed soil about the building foundation will reach undisturbed soil and flow over the undisturbed soil, where it will flow over the rigid edging material and into the lined trench, and then into the sump pit, so that water in the disturbed soil is collected in the sump pit before accumulating under and about the building foundation.
