The invention relates to a geomembrane lining system and method of assembly in which a protective release seal is provided on the weld edges of a geomembrane liner. Geomembrane liners are arranged to line a containment area. Adjacent liners are arranged to partially overlap one another. The side edge of the geomembrane liner have a protective release film over areas of the liners that are to be welded. The protective release film protects the weld edge from accumulating dust and debris prior to and during installation. Dust and debris may disrupt the weld seam and allow contained waste material to leach into the surrounding area. The protective release film is removed prior to or during a welding operation. As a result, the adjacent geomembrane liners are welded together while minimizing or eliminating the presence of dust and debris at the weld edge.

A liquid capture tray and conservation system for capturing agricultural liquids which would otherwise be wasted and could contaminate groundwater. The liquid capture tray has a tray body and a reservoir matrix across the tray body. The reservoir matrix has a plurality of adjacent interconnected concave liquid capture cups, each with a sidewall and bottom wall defining an upwardly disposed reservoir. The tray is positioned below the root zone of a plant growing area to capture liquids that pass through the root zone into the reservoirs of the cups. Apertures in the tray body allow excess liquids to drain from the tray. A connecting mechanism can be utilized to connect two trays together. Cut-outs in the sidewalls of the cups allow liquid to move from one cup to another to disperse liquid across the reservoir matrix. The system includes a growing area, root zone, liquid and liquid capture tray.

A method for ecological filling with mixed coal gangue and fly ash includes the following steps: S1: construction of a double-impermeable base layer: leveling a pit or gully, laying a fly ash-based cementitious material, compacting and curing; spraying a layer of polymer waterproof coating on a surface of the fly ash-based cementitious material, and fully curing to obtain a double-impermeable protective structure; S2: three-dimensional layered filling: dumping coal gangue and fly ash in sequence on the double-impermeable protective structure formed in S1, where the coal gangue and the fly ash are three-dimensionally layered and well graded; the coal gangue is coal gangue after coal washing, which is used as an aggregate; the fly ash is used as a filler and cementitious material to achieve a compact filling structure; and S3: rolling: rolling by a roller after the three-dimensional layered filling.

Composite reinforcing strip comprising: a covering capsule surrounding a plurality of longitudinal channels developing parallel to a longitudinal development direction of the composite reinforcing strip and arranged in sequence between opposite lateral ends of said composite reinforcing strip, a plurality of longitudinal reinforcing fibres arranged inside reinforcing channels of the plurality of longitudinal channels, and a plurality of longitudinal permeable fibres arranged inside at least one permeable channel of the plurality of longitudinal channels.

The covering capsule has, at least at an upper surface of the covering capsule opposite to a lower surface of the covering capsule, a plurality of surface openings leading to the at least one permeable channel so as to define a fluid communication between the plurality of longitudinal permeable fibres and an external environment.

A cover system for preventing water ingress having a geomembrane layer and a wind-disturbing open-pore layer thereon and defining an asperity extent, said open-pore layer for forming in situ an air-flow turbulence zone between the geomembrane layer and a boundary space proximate the open-pore layer as a transition from turbulent flow of wind in the turbulence zone to laminar flow of the wind remote from the geomembrane layer, said open-pore layer inducing disturbance of a wind flow into and through the layer, whereby a suction force on the geomembrane is disturbingly broken by turbulent wind shear events therein and exerted downward pressure deflections, wherein the wind speed and pressure differential lessen and the geomembrane resists uplift. A method of covering a large area surface with a cover system that resists wind uplift is disclosed.

Methods of treating soil contained in a volume of treatment in an underground site and forming a containment barrier within an underground site are contemplated herein. A treatment methodology may be administered upon soil having previously been contained in the volume of treatment. Such a treatment methodology may include the application of an adsorbent to this soil. A layer of micron-sized adsorbents may also be placed on one or more interfaces surrounding the volume of treatment to form a containment barrier operative to mitigate diffusion of contaminants into or from the volume of treatment. Soil in the volume of treatment may be removed to allow for the methods contemplated herein to be performed more simply and effectively. The volume of treatment may then be refilled with a filler.

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 steel wire netting (100, 200) is adapted to be used in erosion control, in geotechnical solutions, in rockfall protection or in aquaculture. The steel wire netting (100, 200) comprises steel wires (300). These steel wires (300) have a steel core (302). The steel core (302) is of a low-carbon or high-carbon nature. The steel wires (300) further have an intermediate metallic coating (306) of zinc or an zinc aluminium alloy or a zinc aluminium magnesium alloy on the steel core (302). The steel wires (300) further have a top coating of a polymer (310). This polymer (310) is a high density polyethylene.

A radon gas and/or moisture abatement system (or method) is located under the concrete slab of a building. The system (or method) includes a multilayered mat having a first layer, a second layer, and a third layer sandwiched between the first layer and the second layer. The first layer is non-permeable and faces the concrete slab. The third (or sandwiched) layer is an entangled net. The second layer is permeable layer. The layers are bonded together. Whereby radon gas and/or moisture are inhibited from entering the building by passing through and collecting in the multilayer product.
