The present disclosure provides a water drainage system comprising: a plurality of lengths of drain pipe comprising a channel and a vertical wall, wherein (i) the vertical wall comprises one or more standoffs extending horizontally from the vertical wall and (ii) wherein the drain pipe comprises a top edge and a bottom edge, each of the top and bottom edges being bifurcated by a v-shaped notch.

The subject of the invention is based on an insulating element, in particular a strip or other insulating element, joined in particular by melting or welding, which is provided on at least one side with a combustible or thermally destructible and electrically conductive element. The invention also relates to a method of inspecting of welds and melting of insulating elements, in particular strips. The invention further provides a control system for welds and melting-down of insulating elements.

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 polymer pre-laid waterproof rolling material, including a polymer base material layer, a pressure-sensitive adhesive layer on the polymer base material layer, and a sand anti-sticking layer on the pressure-sensitive adhesive layer; the pressure-sensitive adhesive layer includes: 25-35 parts by mass of a styrene-isoprene-styrene block copolymer; 32-38 parts by mass of a C5 petroleum resin; 5-12 parts by mass of a 145 pentaerythritol modified rosin resin; 25-32 parts by mass of a naphthenic oil; 0.3 parts by mass of an antioxidant; and 0.5 parts by mass of a UV light stabilizer; the C5 petroleum resin has a softening point of 95-105° C. and a color number of less than 4; the naphthenic oil has a kinematic viscosity of 9-11 mm.sup.2 at 100° C. and a density of 0.8950 g/cm.sup.3-0.9100 g/cm.sup.3 at 20° C. The pressure-sensitive adhesive layer has a stronger bonding effect with sintered sand and further improves the bonding effect with concrete.

The present invention relates generally to an injectable tie back cover for waterproofing, apparatus, and a method of using same. The invention encompasses a substantially domed shaped structure having at least one surface along the domed shaped structure, and having an edge flanged surface which is placed over a tieback head, and where the injectable tieback cover is used as a waterproofing apparatus. A supplemental injectable tubing can also be provided around the outside of the substantially domed shaped structure, which injectable tubing can be injected with a secondary waterproofing material to provide additional waterproofing to the area around the injectable tie back cover facing the concrete or shotcrete. The domed shaped structure can also have at least one dome channel to accommodate at least one injectable tieback cover tubing. The invention also provides a method of using the inventive injectable tie back cover for waterproofing structures.

A radon gas and/or moisture abatement system (or method) is located under the concrete slab of a building. The system (or method) includes a multilayered mat having a first layer, a second layer, and a third layer sandwiched between the first layer and the second layer. The first layer is non-permeable and faces the concrete slab. The third (or sandwiched) layer is an entangled net. The second layer is permeable layer. The layers are bonded together. Whereby radon gas and/or moisture are inhibited from entering the building by passing through and collecting in the multilayer product.

A drainage and ventilation system includes a plurality of drainage cores. Each core includes a sheet having a first and a second end, a first and a second side, and a plurality of dimples disposed between the ends and the sides. The dimples extend outwardly from the sheet and define a plurality of passages. The passages include passages extending from end to end and passages extending from side to side. The system also includes a fabric attached to each core. The passages of the cores receive and convey a flow of at least one of liquid, air and gas through the drainage cores. In one embodiment, the cores are disposed in soil, and the dimples are filled with an adhesive to enhance the shock absorbing properties of the soil. In another embodiment, the dimples are filled a cement-based material for adhering a finish material to the cores.
