A wall structure comprising horizontal concrete base and top beams; two or more concrete vertical support members integrally joined to the base and top beams and meeting at an essentially right angle; wherein the two or more vertical support members define left and right wall boundaries, and wherein the top and base beams define top and a bottom wall boundaries, respectively; an exterior wall shell extending from the left to the right wall boundaries, and extending from the top to the bottom wall boundaries, and continuous with the base and top beams, and the support members; H-shaped insulation encompassing the vertical support members, attachment strips attached to the insulation along its length with fasteners joining the attachment strip to the vertical support member, wherein the fasteners pass though the insulation; and insulation attached to the exterior wall shell between the vertical support members.

A comprehensive dry flood proofing system to mitigate inland flooding risk for existing or new homes and other buildings. The system leverages the home or building's structure to offer practical and affordable inland area flood protection for structures constructed with a slab on grade foundation. The system includes pluggable weep holes, entry door/garage door/window protectors, wall appurtenances and penetration protection, a house wrap and/or debris barrier for wall protection and sewage anti-backflow protection. The system is reusable, easy to deploy, does not detract from the home or building's permanent appearance, allows for ingress/egress during flood events and can protect the home or building from standing water up to 24 above slab elevation. The preparation and installation preflood, the deployment immediately preceding a flooding event and the subsequent removal after a flooding event can be provided by both contractors and homeowners.

Disclosed is a shielding apparatus for high-depth groundwater well pollution prevention grouting comprising: a shielding portion which is provided on the outer circumferential surface of a grouting casing installed in an excavation hole in the ground and compressed to be in close contact with a hollow wall of the excavation hole; a compression portion which is provided on the outer circumferential surface of the grouting casing and formed to descend toward the shielding portion and brings the shielding portion into close contact with the hollow wall of the excavation hole to guide the excavation hole to be sealed; and a pressure equalization injection tube portion which is connected with the compression portion on the outer circumferential surface of the grouting casing and lowers the compression portion by water pressure generated by supplying water from the outside through a water supply tube.

There is provided a geomembrane consisting of a multilayer structure comprising a barrier layer (A), an adhesive layer (B) made of an acid-modified thermoplastic resin and a thermoplastic resin layer (C), wherein the thermoplastic resin layer (C) is laminated on at least one side of the barrier layer (A) via the adhesive layer (B), and the barrier layer (A) has an ethylene unit content of 18 mol % or more and 55 mol % or less and comprises a modified ethylene-vinyl alcohol copolymer comprising a modifying group having a primary hydroxyl group. The geomembrane exhibits excellent peer strength between the barrier layer and the adhesive layer, exhibits further improved peel strength after prolonged exposure to high temperature and high humidity conditions.

A cementitious composite for in-situ hydration includes a structure layer having a first side and an opposing second side, a cementitious material disposed within the structure layer, a sealing layer disposed along and coupled to the first side of the structure layer, and a containment layer disposed along the opposing second side of the structure layer. The structure layer has an intersection at the sealing layer and the containment layer that is at least partially fiberless. The cementitious material includes a plurality of cementitious particles. The containment layer is configured to prevent the plurality of cementitious particles from migrating out of the structure layer.

A barrier tape comprises a barrier section comprising one or more barrier layers and one or more adhesive layers adhered to a face of the barrier section. The barrier tape can be used to join together adjacent barrier sheets or to patch a breach in a barrier sheet to form a barrier assembly.

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.

The present invention relates to a method for reducing a flow of soil air to the indoor air in a building (1), wherein the building comprises at least one wall (2), which wall comprises a permeable channel (23) connected with soil air, wherein the method comprises achieving a flow stop (24) for the soil air in the permeable channel (23). The invention also pertains to a device to reduce the flow of soil air to indoor air in a building (1).
