A drain assembly for 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 system for retaining a flowable and curable building material to form a portion of a foundation includes side walls disposed in a predetermined configuration having a first side wall and a second side wall, and at least one component having an interior cavity disposed in one of the side walls. A bracket assembly includes an outwardly bounding reinforcement post for each of the side walls, a separator bar having a plurality of apertures sized to receive and retain each of the reinforcement posts at locations corresponding to nominal widths of the at least one component. A barrier is disposed between the outwardly bounding posts. The barrier and the component in the side wall is retained in the foundation after the building material cures. The barrier prevents backfill from filling a volume between the outwardly bounding posts.

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 multi-function retaining structure for excavation and drainage operations during construction process and a method for excavation and implementation of a multi-function retaining structure at a target location. The multi-function retaining structure includes a first I-beam, a second I-beam, a third I-beam, a first inclined stiffener plate, and a second inclined stiffener plate. The method includes positioning the multi-function retaining structure above the target location, driving the multi-function retaining structure into the target location by pushing the bottom edge of the third web into the target location, softening soils in the target location by jetting water to the soils utilizing a first water jet tube and a second water jet tube, extracting the first water jet tube and the second water jet tube from the rectangular chamber, and draining water from the rectangular chamber by utilizing a water drainage pump and through a drainage tube.
