The present disclosure provides a water drainage system comprising: a plurality of lengths of drain pipe comprising a channel and a vertical wall, wherein (i) the vertical wall comprises one or more standoffs extending horizontally from the vertical wall and (ii) wherein the drain pipe comprises a top edge and a bottom edge, each of the top and bottom edges being bifurcated by a v-shaped notch.

The present invention relates generally to an improved below grade, blind side, dual waterproofing membrane assembly incorporating a sheet membrane with adhesive to fully bond to concrete/shotcrete, and a method of making and using same. More particularly, the invention encompasses a 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 innovative 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 most effectively used between a concrete or shotcrete layer and the surrounding earth, such as, along an area that has a high water table or ground moisture or hydrostatic pressure that may creep into a foundation or a wall. The inventive system comprises two different waterproofing layers, and materials.

A system and method for installing a membrane-lined wall for levee reinforcement or leak prevention. The installation system may comprise a sled positioned above the trench having a length, and may comprise a frame and support members, and a weight suspension system mounted on the frame to lower an elongated weight into the trench. The liner installation sled may also include a liner roller rotatably mounted on the frame, the liner roller adapted to hold a roll of a liner above the surface on a first side of the trench when the liner installation sled is in an installation position relative to the trench, wherein a longitudinal axis of the roll of liner can be aligned with the length of the trench. The elongated weight is usable to force the liner into the trench.

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.

A trough plate for constructing a locked polymer anti-seepage wall includes a plate body, a guide tube, a grouting pipe and an anti-blocking head. A construction method of the locked polymer anti-seepage wall includes the steps of positioning an N.sup.th trough plate and then pressing the N.sup.th trough plate into ground, wherein N is a natural number larger than and equal to 1; engaging an (N+1).sup.th trough plate with the N.sup.th trough plate, and then pressing the (N+1).sup.th trough plate into the ground; connecting a grouting pipe of the N.sup.th trough plate with a grouting machine, pulling out the N.sup.th trough plate, and simultaneously grouting through the grouting pipe of the N.sup.th trough plate by the grouting machine; and repeating the steps (B) and (C) till the locked polymer anti-seepage wall is completed, wherein the steps (B) and (C) are repeated every time, N is automatically increased by 1.
