A complete decreased mistake-proof high-reliability waterproofing system is revealed that integrates the waterproofing membrane, drain panel, and abrasion-protected filter fabric, using a factory-controlled process; furthermore, the system incorporates intrinsic devices for installation verification and leak-detection, and the potential for in situ mapping of the functional topography of the waterproofing installation over time.

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.

The present invention relates to a below grade, blind side, improved 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.

An assembled subway station and a construction method thereof are provided. The assembled subway station includes a plurality of components combined in a ring shape, comprising a bottom plate component, two bottom corner components, two side wall components, a middle plate component, two top corner components, and a top plate component. Connection surfaces of each component are each provided with a concave-convex structure being matched with another concave-convex structure on a relevant connection surface of an adjacent component. Butt joint positions of two adjacent components are filled with sealing structures. The embedded grooves of two adjacent components are oppositely arranged, and connecting members for exerting opposite fastening forces on the two adjacent components are installed in the oppositely arranged embedded grooves. The opposite fastening forces are exerted on the two adjacent components through connecting members to ensure sealing structures at the butt joint position and achieve better sealing effects.

A universal barrier system includes universal barrier components that may be assembled together to shield floors and walls from moisture and provide a thermal break in an operational area of the universal barrier component. A lap zone of the universal barrier component may allow universal barrier components to be assembled and installed to protect floors, walls, ceilings, footings and the like from moisture and heat gain or loss by minimizing the need for tapes and other joining methods. The universal barrier system may also act as a sound deadening material. The operational area and lap zone of the universal barrier component may be disposed on a vapor block layer to provide some rigidity. The operational area of the universal barrier component may include a thermal break disposed upon the vapor block layer. The thermal break may include an outer protective layer. In addition, universal barrier tape and universal barrier edging may be provided to couple adjoining universal barrier components.

A sump overflow protection system for use in a building having a floor and a drainage field for collecting water from the perimeter of the building. The sump overflow protection system includes a portion of the floor proximal an opening of a sump crock having a first level defining a base and wherein the rest of the bottom floor generally has a second level higher than the first level of the basin surface of the floor and communicates water overflowing the sump crock to an outlet coupled to a building drainage outlet separate from the sump crock and to be located in the basin surface of the floor and spaced a predetermined distance from the sump crock.

A method for forming a trench and a membrane-lined wall in the trench for levee reinforcement or leak prevention, prevention of water migration, and pollution control of impoundments. The membrane-lined wall generally includes a cementitious or concrete wall formed within an excavated trench. The concrete may be internally reinforced, and the wall may also comprise a double-layer of impermeable geomembrane liner that forms a barrier between the concrete and the sides and bottom of the trench. The membrane or liner reduces water migration, prevents levee leakage, and prevents the escape of contaminants in impoundments.
