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.

The present invention provides a multi-layer barrier assembly or device for post-installation injection of a resin, grout, or other fluid. The barrier device comprises first and second layers defining an intermediate open-matrix layer, and at least one injection conduit member in parallel orientation with respect to the first and second layers and having openings for injecting fluid into the intermediate open-matrix layer. The injection conduit may be located between and in parallel orientation with respect to the first and second layers, along an edge of the first and/or second layers, along an outer face of the first layer (if the first layer is a woven or nonwoven fabric), or at any combination of these locations, to enable fluid to be conveyed into the intermediate open-matrix layer. The invention also provides for use of a gel activator within the barrier device cavity, such as pre-installed on open-matrix structure which used for separating the first and second layers of the barrier device, such that a highly flowable injection fluid can be introduced into the device, and its gelation or hardening will be initiated or accelerated by the presence of the gel activator. This will allow for low power grout pumps to be used and facilitate the sealing of fine cracks in the surrounding concrete.

The present disclosure provides a method of biocementation comprising contacting a granular, cohesionless soil with a solution, wherein the solution comprises urea, urease, a source of calcium ions, and a source of non-urease proteins, wherein the urea, urease, source of calcium ions, and source of non-urease proteins are provided in effective amounts suitable to cause crystallization of calcium carbonate.

A coating film capable of being peeled off in the shape of sheet to facilitate a coating film removal work, and is less likely to peel even after long periods of use on an underwater structure is provided. The coating film comprises an undercoat layer to be bonded to an underwater structure, and an antifouling layer bonded to the undercoat layer, wherein: a 100-gram underwater constant load peeling degree of the coating film is less than 5; a ratio of a tensile breaking strength of the coating film to an adhesive force of the coating film with respect to the underwater structure, as measured after immersing the coating film in pure water at 60° C. for 5 weeks is 1.5 or more; and a 1-mm square cross-cut stretching-caused peeling degree of the antifouling layer with respect to the undercoat layer is 0.05 or less.

An erosion control system is disclosed for preventing erosion of embankments including a three-dimensional material, the three-dimensional material including void volumes, and a mixture including a particulate material and a binder material included in the void volumes, wherein the binder material includes an organic binder material derived from living matter.

A manufactured composite comprising synthetic turf and impermeable geomembrane is used in a single-layer capping system as the single layer to provide permanent, impermeable and functional aesthetic cover for a job site. During installation of composite pieces at a job site, an edge portion of a tufted section of a second composite piece is overlaid onto an edge untufted section of the first composite piece already laid and anchored over foundation soil to form a reinforced overlapping seam, through which the two composite pieces are physically and permanently joined together. As composite pieces are joined together, the continuity of synthetic grass and the continuity of impermeability are extended and realized over the entire site to form permanent, impermeable and functional aesthetic cover for a job site.

The invention relates to a below grade, blind side, waterproofing sheet membrane with adhesive and high reflectivity granular particle layer, and having a top release liner, and a bottom release liner, enhancing bond strength between sheets, and be able to fully bond to concrete/shotcrete, and a method of making, and using same. The inventive waterproofing sheet membrane with adhesive, has at least one layer of high 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 between about 35 percent to 80 percent reflectivity on a standard reflectivity scale. The waterproofing sheet membrane has an adhesive layer having embedded therein high reflectivity granular particles is used in any building or wall construction, and can be placed under or around a foundation of a building or on its below grade blind side retaining walls, etc.

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.

Landscaping walls, systems and methods of manufacturing and installation of such walls include in aspects a fiberglass based wall having a decorative front side and a back side having at least one conduit where the conduit receives a cable or fastener extending outward from both ends of the conduit to connect to a stake to be inserted into ground adjacent the wall. The conduit in one aspect is a PVC tube mounted vertically against the wall and in aspects is embedded within the wall. The conduit allows for self-adjustment of the cable while also providing solid anchoring of the wall to prevent movement. The wall and system is lightweight, good looking and easy to install.
