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.

Composite walls have the structural components connected to form a substantially unitary structure. A composite wall is described that includes a block and/or brick wythe adhered to a poured concrete wall. The composite wall may also have a panel sheet material adhered to the poured concrete opposite surface of the poured concrete wall. Further, the composite wall may include a first wythe comprising concrete blocks, bricks, or a combination thereof, a poured concrete core, and a rigid insulation panel, wherein at least a portion of the blocks and/or bricks of the first wythe are adhered to a first surface of the concrete core and the rigid insulation panel is adhered to a second surface of the poured concrete core. Wire ties may extend from the mortar joints in the first wythe through the rigid insulation panel.

A porewater pressure dissipater is disclosed. In one example, a disclosed dissipater includes aggregate; a cylindrical receptacle for receiving the aggregate; a plate having a top surface and a bottom surface and one or more openings transcending from the top surface to the bottom surface wherein the plate secures and compacts the aggregate in the cylindrical receptacle; and one or more access tubes coupled to the top surface of the plate wherein the one or more access tubes are positioned over the one or more openings thereby forming a passageway to the cylindrical receptacle. The disclosed dissipater allows piles and shafts to be embedded at the optimum depth without concerns of liquefaction.

A layered material configured for assembly of a base mat containment system is provided. The layered material includes: a first layer affixed to a barrier layer, a second layer affixed to the barrier layer, the second layer including a plurality of peaks and valleys. The base mat includes a high-strength material. A method of fabrication and a base mat containment system are disclosed.

The present invention provides methods and articles for achieving puncture-resistant waterproofing membranes and for waterproofing building and civil engineering surfaces without requiring the use of separate protection boards. Exemplary membranes and methods of the invention rely on relatively thin, flexible composite layers to provide impact resistance while yet facilitating seaming between adjacent installed membranes and minimizing formation of wrinkles, leakage channels, and fish mouth openings, particularly at substrate details or other surface irregularities.
