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.

Wax-modified asphalt can be employed in peel-and-stick sheets. In some embodiments, the method includes adding a wax to an asphalt blend. The addition of wax can result in an asphalt having lower viscosity, higher softening point, improved compatibility, and/or stronger adhesion properties. These changes can be achieved in addition to maintaining both low and high temperature stability of the asphalt adhesive. In some embodiments, the wax is made from a recycled plastic.

A sump system includes a catch basin and a sump pump. The catch basin is configured to receive runoff water. The catch basin has an upper end and a bottom surface. The catch basin defines a vertical chamber and a horizontal chamber. The vertical chamber extends downward in a vertical direction from the upper end to a first portion of the bottom surface. The horizontal chamber intersects the first chamber to form an intersecting region. The horizontal chamber is defined by an upper surface and a second portion the bottom surface. The horizontal chamber extends outwardly in a horizontal direction from an outer periphery of the first chamber and has a vertical dimension that extends upward from the bottom surface to the upper surface. The upper surface is positioned below the upper end. The sump pump is disposed within the catch basin.

A water drainage edging segment includes a horizontally-extending bottom portion, a vertically extending top portion, and an angled intermediate section spanning between the bottom and top portions. The bottom portion defines a plurality of longitudinally spaced bottom channels that are oriented at one or both of a perpendicular angle and an oblique angle to the longitudinal axis of the edging segment. Each of the plurality of bottom channels are raised above a lowermost plane of the bottom portion to define an open passageway from a backside of the edging segment and laterally through the edging segment. The top portion defines a longitudinally extending upper rib portion that projects rearwardly from a front plane of the top portion to define a forward offset of the front plane and an upward facing contact surface.

A membrane-lined wall for levee reinforcement or leak prevention, prevention of water migration, and pollution control of impoundments. The membrane-lined wall generally includes a cementitious or concrete wall formed within an excavated trench. The concrete may be internally reinforced, and the wall may also comprise a double-layer of impermeable geomembrane liner that forms a barrier between the concrete and the sides and bottom of the trench. The membrane or liner reduces water migration, prevents levee leakage, and prevents the escape of contaminants in impoundments.

A sheet for use in ground works, the sheet having an upper face with an plurality of openings therein, a lower face configured so as to permit liquid to drain through the sheet and a spacing arrangement to separate the upper face from the lower face and define a volume therebetween, where the volume is capable of receiving an infill material via the openings in the upper face. The lower face of the sheet is configured to be interengageably secured to an upper face of a similar further sheet.
