Abstract: A system adapted to remove radon gas and drainage liquid from a subterranean chamber or basement having a floor and an ambient environment. The system has a drainage channel forming a drainage portion and a venting portion. A valve is located between the drainage portion and the venting portion. Drainage liquid flows into the drainage portion and from the drainage portion through the valve into the venting portion. A pressure gradient is between the drainage portion and the venting portion. The valve substantially prevents the ambient environment from entering the venting portion while allowing drainage liquid to flow from the drainage portion into the venting portion.

Abstract: The present invention 10 discloses a concrete form system for building foundations wherein two substantially parallel form walls 12 are constructed using a plurality of retainer sections that can mechanically interlock end-to-end 42, 44 when the retainer sections 14, 16, 18, 20 incorporate a throughbore 22 or butt-up end to end when there is no throughbore. Additionally the present invention provides a separator bar and reinforcement posts whereby the separator bar 24 serves as base for the retainer sections and as spacer between stacked retainer sections 14, 16, 18, 20 which can in cross-section have a circular, oval or polygonal shape and in one additional element a ribbed exterior portion 46, 48 for added strength and a substantially hollow interior 22 that forms a corrugated conduit retainer 20 that is conducive to providing ventilation for effective and efficient radon remediation from the structure being constructed.

Abstract: A method for transforming a waste product containing or completely formed of amiantus comprising subjecting the waste product to several working phases and adding of components such as calcined alumina, clay and material having a given porosity so to produce a final manufactured product free of any amiantus.

Abstract: A waterproofing and humidity control system is provided for a building which includes drain members located in trenches provided in ground beneath and adjacent the basement of the building. A suction and fan and motor assembly is located within a housing positioned within the building. Conduits communicate with the drain members and the motor and fan housing. An exhaust vent is located in the wall of the building spaced from the motor housing and has an air inlet and outlet. A separate conduit or duct communicates with and connects the inlet of the vent with an outlet of the motor and fan housing. The duct may extend between joints in the wall of the building. An adapter conduit is used with the system and is positioned between the motor and fan housing and the duct. The adapter conduit has portions which are offset from each other to allow the fan housing to be positioned in front of a finished basement wall.

Abstract: An environmental protection and detection system includes a vapor and gas impervious barrier extending beneath at least part of the area of an enclosure to prevent fluids leaked or spilled within the enclosure for flowing downwardly into the underlying soil and ground water and to prevent vapors and gases emanating from sources beneath the enclosure from percolating upwardly into the enclosure. Lengths of perforated pipe are positioned above the barrier and are connected to points outside the enclosure for use in detecting and removing contaminants leaked or spilled within the enclosure. Lengths of perforated pipe are positioned beneath the barrier and are vented to the atmosphere for preventing accumulations of fluids emanating from sources beneath the enclosure.

Abstract: An enclosure for housing people in the event of a serious air quality degradation is provided. A pressurized enclosure, either permanent or temporary, includes an air supply system for filtering and subsequently supplying clean air to the interior of the enclosure. The structure will be deployable and/or activated from a remote control station or from the protective structure itself. Life support elements are stored in the enclosure for use as needed.

Abstract: A modular structure consisting of three modular units, the center module being the primary module containing the mechanical components of the building, with plumbing, air conditioning and heating ducts, and electrical wiring in the slab floor structural foundation and door jambs. The primary module is completed at the factory. The major exterior walls, slab floor foundation panels, and ceiling/roof panels for all three modules are similarly manufactured in one piece. The major components of the side modules, consisting of the slab floor foundation panels, ceiling/roof panels and the exterior side walls, are all hinged so that they fold to the side and on top of the primary module. Accessories and wall panels and partitions not hinged are placed on top of the primary module for transportation. Two end walls are bolted to the center module during transportation to the site.
