Disclosed herein is a system for draining groundwater away from a substantially vertical foundation wall that extends beneath the surface of the ground, and which has an exterior surface in contact with the ground. The drainage system includes a drainage structure that extends longitudinally along an entire interior foundation wall footing. The drainage structure is fabricated from a plurality of foldable polypropylene panels that are secured to and are adjacent to the foundation footing. The drainage structure forms a drainage channel that facilitates the flow of infiltration water to a sump pump or other means for ejecting water, and extracted radon, from proximate the foundation.

A water management system provides much improved waterproofing drainage system particularly, but not limited to foundations, new or existing. The includes a form, clean washed stone, soil separating filter cloth, backfilling soil, and drainage pipe to drain out all water away from the structure. This system is easily installed and creates an even “wall” of gravel around structural walls minimizing the costs of materials making it very cost-effective. This system removes all hydrostatic pressure from structural walls eliminating the cause of water infiltration to the interior of basement walls. Water infiltration in basement walls results in mold, mildew, high humidity, and poor air quality.

A drainage system to be installed against a foundation of a building. The drainage system includes a drainage board having a plurality of channels extending from a bottom side along a front face thereof, and a portion of filter fabric attached to a rear face of the drainage board that covers the front face of the drainage board. The plurality of channels comprise a plurality of left channels and a plurality of right channels that intersect to form a crisscross pattern.

The present invention relates to a below grade, blind side, improved dual waterproofing membrane assembly incorporating a secondary membrane comprising of a bentonite sheet waterproofing layer, and a primary membrane comprising of a sheet membrane having an adhesive to fully bond to a concrete/shotcrete. The invention encompasses a dual layer or dual membrane system that acts as a barrier, and prevents, and blocks water and moisture, from passing from one side of the structure to the other side. The dual barrier layer system can be used along a wall, a floor, a ceiling, or along any structure which requires water or moisture proofing. The invention can be used between a concrete or shotcrete layer and the surrounding earth, such as, along an area that has a high water table, or a constant hydrostatic pressure, or high ground moisture, that may creep into a foundation or a wall.

The present invention relates generally to a below grade, blind side, waterproofing sheet membrane with adhesive and moderate reflectivity granular particle layer to fully bond to concrete/shotcrete, and a method of making, and using same. More particularly, the invention encompasses a below grade, blind side, waterproofing sheet membrane with adhesive, and having at least one layer of moderate reflectivity granular particle layer that are fully or partly embedded into the adhesive layer, and where the average reflectivity of the exposed granular particles is below 55 percent reflectivity on a standard reflectivity scale. The inventive waterproofing layer having the waterproofing sheet membrane, and an adhesive layer having embedded therein moderate reflectivity granular particles can be used in any building or wall construction, and can be placed under or around a foundation of a building or dwelling or on its below grade blind side retaining walls, etc.

Disclosed is a pumping method of a large-diameter horizontal pressurized long dewatering well for inexhaustible pumping strata. Clay layers and sand soil layers are determined according to construction positions of foundation pits, horizontal holes are drilled in the sand soil layers with a drill rig with simultaneous casing, and after the designed depth is reached, horizontal wells are placed, the horizontal wells are located above the junction of the clay layers and the sand soil layers, and the horizontal wells comprise drain pipes and air ducts, the drain pipes and the air ducts are located at the same elevation, each air duct is located between the two drain pipes, and the air duct is connected with the air pipe of the air compressor to deliver and pressurize, so as to facilitate water in the strata of aquifer to gather into the drain pipes.
