A drainage device for use under the floor of a building to facilitate drainage of water along a foundation of the building under the floor. The drainage device can include a corner drainage device that is capable of assuming a number of near 90 degree shapes so that the drainage device can be easily fitted to the corner of the foundation. A bridge drainage device permits more rapid installation of the drainage devices. The bridge device can be used to bridge between two drainage devices so that it is not necessary to cut the drainage devices precisely to fit on a footing of any selected length.

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.

The inventive disclosures are directed to an improved waterproofing membrane that features a polymer backing membrane with an integrated electrically-conductive layer that is used to create improved asphaltic waterproofing membranes and sodium-bentonite-clay waterproofing panels with intrinsic leak-detection capability for applications in below-grade waterproofing systems and above-grade air-barrier systems and horizontal roofing and deck-coating applications. Additionally, improved composite fluid-applied waterproofing membranes with intrinsic leak-detection capability is revealed.

A draining construction wrap includes a pliable moisture impermeable layer having interior and exterior surfaces. A drainage framework is configured to channel moisture across the exterior surface of the pliable moisture impermeable layer. The drainage framework includes a plurality of support struts. Each of the support struts includes a base strut portion coupled with the exterior surface, a strut support face, and a strut body extending from the base strut portion to the strut support face. A plurality of drain channels are between the support struts. The draining construction wrap includes an installation surface configured for coupling with an outer wall. The installation surface includes the strut support faces of the plurality of support struts. The strut bodies of the plurality of support struts brace the installation surface and the pliable moisture impermeable layer is recessed from the installation surface with a strut gap therebetween.

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.

A drainage system to be installed against a foundation of a building. The drainage system includes a drainage board having a plurality of channels extending from a bottom side along a front face thereof, and a portion of filter fabric attached to a rear face of the drainage board that covers the front face of the drainage board. The plurality of channels comprise a plurality of left channels and a plurality of right channels that intersect to form a crisscross pattern.

A water management system provides much improved waterproofing drainage system particularly, but not limited to foundations, new or existing. The includes a form, clean washed stone, soil separating filter cloth, backfilling soil, and drainage pipe to drain out all water away from the structure. This system is easily installed and creates an even wall of gravel around structural walls minimizing the costs of materials making it very cost-effective. This system removes all hydrostatic pressure from structural walls eliminating the cause of water infiltration to the interior of basement walls. Water infiltration in basement walls results in mold, mildew, high humidity, and poor air quality.

A mat made of waterproof plastic material for the sub-base of synthetic turfs or pavings and the like includes one or more coupling elements for mutual interconnection with other mats so as to compose a single turf for the complete covering of a predetermined bed surface. The mat is divided into at least two longitudinal portions which are mutually connected by an expansion joint component adapted to compensate for the thermal expansions and contractions by deforming.

A mat made of waterproof plastic material for the sub-base of synthetic turfs or pavings and the like, adapted to be arranged between a bed surface and a covering layer: includes a membrane having a lower face adapted to be rested on the bed surface and an upper face adapted to be covered by the covering layer;

The mat further includes one or more coupling elements for mutual interconnection with other mats so as to compose a single turf for the complete covering of a predetermined bed surface. Thehe lower face and the upper face include a plurality of ribs adapted to absorb and return mechanical stresses. The ribs include longitudinal lines which form channels for the horizontal draining of the water on the upper face.

A functional sheet manufactured with staple fibers is provided. More particularly, a functional sheet is formed as a single layer or a composite layer by binding polyolefin staple fibers by needle punching, to enhance physical properties of the functional sheet so that the functional sheet may be used for various purposes, for example, for weed growth prevention, waterproofing, soundproofing, ground stabilization, civil engineering, construction and aging-friendly materials.
