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.

A drain assembly capable of being placed inground includes a first panel and a second panel spaced-apart from the first panel, a plurality of supports extending between the first panel and the second panel, a bottom or pipe extending between a bottom portion of the first panel and the second panel, and a cap extending between a top portion of the first panel and the second panel. The first panel may define a plurality of drainage apertures. A related method is also provided.

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.

A dual channel drainage seal for enclosing a joint between a slab and a foundation sidewall of a subterranean area. The drainage seal includes and lower channel and an upper channel stacked over the lower channel. The lower channel is affixed on top of the slab and against the sidewall to form and enclosed channel for retaining and routing radon and/or water seepage at the joint to a sump pit. The upper channel is open on top and configured to capture and route water seepage from the sidewall above to the sump for discharge, thereby protecting the interior portions of the slab from radon and water damage.
