The present invention relates to a below grade, blind side, dual waterproofing membrane assembly incorporating a secondary membrane comprising of a bentonite sheet waterproofing layer, and a primary membrane comprising of a sheet membrane having an adhesive to fully bond to a concrete/shotcrete. The invention encompasses a dual layer or dual membrane system that acts as a barrier, and prevents, and blocks water and moisture, from passing from one side of the structure to the other side. The dual barrier layer system can be used along a wall, a floor, a ceiling, or along any structure which requires water or moisture proofing. The invention can be used between a concrete or shotcrete layer and the surrounding earth, such as, along an area that has a high water table, or a constant hydrostatic pressure, or high ground moisture, that may creep into a foundation or a wall.

A vapor mitigation apparatus and method for use with the construction of a building. The apparatus includes a vertical member configured to be affixed to a foundation wall proximate a footing that is supporting the foundation wall. The vertical member has a first end located proximate to a footing and a second end. A horizontal foot is located at the first end of the securing piece. The horizontal foot is configured to rest against the footing. The apparatus may include a mechanical clip located at the second end of the vertical member and is configured to secure a gas impermeable membrane. In the alternative, the vertical member and the gas impermeable membrane are of a unitary structure. The method includes securing the apparatus to the foundation wall, sealing the gas impermeable membrane to a membrane that is covering the footings or granular base of the building and then creating a concrete slab by pouring concrete over the footing and apparatus. The apparatus may also include a membrane material and a rigid ring located at the approximate center of the membrane material. An inner portion of the membrane material is located inside the perimeter of the ring. The rigid ring is configured to be located around one of the at least one penetration such that the inner portion of the membrane material is configured to stretch around the one penetration resulting in the sealing of the apparatus to the penetration.

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. 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.

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 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 waterstop assembly for use as embedded components in at least a pair of adjacent concrete slabs, defining elongated first and second waterstop panels including a main body sheet to which is mounted by coextrusion or insertion to both of its opposite top and bottom ends a soft expansible flange made from hydrophilic thermoplastic material. Each hydrophilic soft flange has such an expansion capability as to provide strong radially outward pressure applied by the soft flange against the adjacent concrete slabs, thus providing watertight interconnection therebetween. A welding block is taken in sandwich between overlapping transitional end portions of the first and second waterstop panels. Integral ridge and groove connectors interconnect the welding block with the waterstop panels. Resistance wires connected at one end to an electric power source fuse the welding block and the first and second waterstop panels, wherein a watertight joint is formed therebetween. An upright steel post is mounted spacedly parallel to a corresponding one of first and second waterstop panels, and a transverse anchor arm transversely spacedly retaining waterstop panel in upright operational condition parallel to the steel post before and during first concrete pour.

An insulation board assembly includes an insulation board body that has a front face, a back face, a top edge, and a bottom edge. The back face has a drainage channel extending from the top edge to the bottom edge. A drainage insert is positioned in the drainage channel proximate the bottom edge of the insulation board body. The drainage insert has a front face, a top edge, a bottom edge, and two side edges, and an insert height measured between the top edge and the bottom edge of the drainage insert. The drainage insert defines at least one interior drainage passage extending from the top edge of the drainage insert to the bottom edge of the drainage insert. A channel height of the drainage channel is preferably at least twice the insert height.

A track-type shotcrete integrated system includes: a proportioner working bin, a storage bin, a power bin, and load-bearing legs, wherein bottom sections of the load-bearing legs are equipped with a track chassis for moving, and the track chassis is electrically connected to a track controller; the storage bin contains a storage tank I and a storage tank II for storing different raw materials; a feed pump I is installed on a top of the storage tank I, and a feed pump II is installed on a top of the storage tank II; inlet pipes of the feed pump I and the feed pump II insert into the storage tank I and storage tank II respectively, and outlet pipes of the feed pump I and the feed pump II are connected to a feed pipe I and a feed pipe II respectively . . .
