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 temporary radiotherapy facility for use during renovation, upgrading, and/or modernization of an existing facility. The radiotherapy facility includes a central vault room containing a radiation emitting device and a platform for holding a quantity of radiation shielding material above the central vault room. The platform is supported by shear walls that are disposed outside the sidewalls of the central vault room such that the radiation shielding material is supported and suspended above the central vault room without being in contact with or bearing upon the central vault room or affecting the height or level of the central vault room.

A geosynthetic sensor that incorporates an arrangement of a first layer of lengths of electrically conductive geosynthetic and a second layer of lengths of electrically conductive geosynthetic where each said length undergoes a change in electrical resistance or capacitance when subject to changes in any one or more of: pressure; strain; water content; or temperature.

A radon gas mitigation system and kit for a building with a crawlspace comprises a plurality of radon gas intakes arranged under a vapor barrier in the crawlspace to be in a subterranean environment and outside a building envelope. The intakes are arranged to be respectively registered with one of plural foundation walls and collectively arranged to generally follow the building footprint. The intakes are arranged in spaced relation to the foundation walls. A manifold is arranged in the building envelope and in fluidic communication with the intakes; a fan in the building envelope and in fluidic communication with the manifold and configured to generate an airflow to draw radon gas from the subterranean environment and to the manifold; and an outlet arranged in the building at a location above a grade of ground and in fluidic communication with the manifold and configured to release the radon gas to the outside.

A clamping tool (1) is disclosed suitable for securing underwater protective shields, jackets and covers. A system is also described comprising the clamping tool and a protective shield, jacket or cover. The clamping tool (1) comprises a clamp (2), a jaw attachment (12) and a plurality of locking bolts (46). The clamp (2) comprises a first claw (20), a second claw (22), and a pivot (3). The jaw attachment (12) comprises a first tube (40) connected to the first claw (20) and a second tube (42) connected to the second claw (22). The first tube (40) and the second tube (42) comprise a plurality of holes (44) for receiving the plurality of locking bolts (46) and the pivot (3) is configured to transform a rotational torque applied by a user into a clamping pressure of the jaw attachment (12).

The present invention relates generally to a below grade, blind side, waterproofing sheet membrane with adhesive and low reflectivity granular particle layer to fully bond to concrete/shotcrete, and a method of making, and using same. More particularly, the invention encompasses a below grade, blind side, waterproofing sheet membrane with adhesive, and having at least one layer of low reflectivity granular particle layer that are fully or partly embedded into the adhesive layer, and where the average reflectivity of the exposed granular particles is about 50 or below 55 percent reflectivity on a standard reflectivity scale. The inventive waterproofing layer having the waterproofing sheet membrane, and an adhesive layer having embedded therein low reflectivity granular particles can be used in any building or wall construction, and can be placed under or around a foundation of a building or dwelling or on its below grade blind side retaining walls, etc.

A comprehensive dry flood proofing solution to mitigate inland flooding risk for existing or new homes and small buildings. This family of integrated systems of the present disclosure each leverage the building's structure to offer practical and affordable flood protection for those buildings constructed with slab-on-grade foundations. This family of solutions includes pluggable weep holes, entry door/garage door/window protectors, wall appurtenances and penetration protection, house wrap and debris barrier system for wall protection and sewage anti-backflow protection. The components of the solution are reusable, easy to deploy, and do not detract from the building's permanent appearance. Furthermore, the solution allows for ingress/egress during flood events and can protect the building from standing water incursion up to 24″ above slab elevation. The pre-flood design and preparation, the deployment immediately preceding flooding event and the subsequent removal after flooding event has passed is provided by both contractors and homeowners.

Systems and methods of the present invention include a method for the treatment of drilling wastes and coal combustion residues, comprising combining at least a first drilling waste with coal combustion residues to form a paste, combining at least a second drilling waste with coal combustion residues to form a compactable fill, and placing the paste and the compactable fill in a landfill. Other embodiments include a method of treating drilling wastes and coal combustion residues, comprising combining at least one drilling waste with a coal combustion residue to form a paste. Further embodiments include containing the paste within at least one geotextile container. Still further embodiments include placing the geotextile container in a landfill.

An electrically conductive geotextile incorporating graphene and a method of using conductive properties in same to detect anomalies in said textile.

Improved containment mats and systems of containment mats may include multiple adjoining mats with a top surface and a bottom surface. The multiple mats may provide a modular structural mat system that may be installed at a drill site, with multiple mats placed adjacent to each other with a lap joint connecting adjacent mats. A geotextile may be used to cover the lap joints and a coating applied to the geotextile. Such a system may provide containment of potential spills, a reliable working surface for drilling operations, and relatively fast and less expensive installation.
