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.

An erosion control system of interconnected bags with water permeable fill material. The top panel of each bag is a geotextile mesh material so that water can pass into the bag and into the water permeable fill material. The bottom panel of each bag is a geotextile mesh that is non-degradable and slightly water permeable. The bags are connected in the end to form a trough through the permeable fill material.

A load-retention panel having an anchor rod on a load-bearing side thereof forming a horizontal slot therebetween. A securing rod having a diameter greater than or equal to a width of the slot and seated against the load-retention panel and the anchor rod on a first side of the slot. A first section of a flexible sheet extends between the anchor rod and the securing rod and wraps about the anchor rod and the securing rod on opposite sides thereof. The distal end of the flexible sheet extends away from the load-retention panel into and within a landfilling material. The flexible sheet may further wrap about a combination of the anchor rod, the securing rod, and the first section of the flexible sheet with its proximal and distal ends extending through the slot from the first side thereof, and out of the slot from an, opposite second side.

A low-profile fluid collection conduit includes an elongate outer cover having an upper portion and a lower portion generally opposite the upper portion, with the outer cover being much wider than it is tall and defining an interior volume. An elongate rigid spacer is fitted within the interior volume of the elongate outer cover, with the elongate spacer allowing the majority of the interior volume to be unfilled so as to permit the flow of fluid along and within the elongate outer cover. The collection conduit is used with a fluid-impermeable membrane as part of a landfill fluid collection and conveyance system.

Systems and methods of restoring a lake including dredging, island creation, water treatment, real estate development, computer modeling of environmental conditions, wave height reduction, sediment removal and encapsulation, bathymetry contouring, littoral zone restoration, plant restoration, and/or fish restoration.

A porewater pressure dissipater is disclosed. In one example, a disclosed dissipater includes aggregate; a cylindrical receptacle for receiving the aggregate; a plate having a top surface and a bottom surface and one or more openings transcending from the top surface to the bottom surface wherein the plate secures and compacts the aggregate in the cylindrical receptacle; and one or more access tubes coupled to the top surface of the plate wherein the one or more access tubes are positioned over the one or more openings thereby forming a passageway to the cylindrical receptacle. The disclosed dissipater allows piles and shafts to be embedded at the optimum depth without concerns of liquefaction.

A method of manufacturing an erosion, sediment and pollution control product comprises heat treating a rice hull filler material for sterilizing the rice hull filler material and increasing the pollutant affinity of the rice hull filler material; filling a tubular containment member with the rice hull filler material in a manner allowing fluid to flow through the containment member and the rice hull filler material. The containment member is a geotextile which may include cellulose based threads treated to be hydrophobic.

The present disclosure provides a geosynthetic. In one embodiment, the geosynthetic contains a composition containing (A) a polypropylene and (B) from greater than 0 wt % to less than 3 wt % of a halogen-free flame retardant, based on the total weight of the composition. In another embodiment, the geosynthetic contains a composition containing (A) a polypropylene and (B) greater than 20 wt % zinc sulfide, based on the total weight of the composition. In another embodiment, the geosynthetic contains a composition containing (A) a polypropylene; (B) a halogen-free flame retardant; and (C) greater than 20 wt % zinc sulfide, based on the total weight of the composition. The composition has a specific gravity greater than 1.00 g/cc.

A method for reinforcing soft ground by post-grouting combined with pressurized vacuum preloading is proposed, by pre-burying prefabricated vertical drains and air-boosted pipes in granular material piles, and the air-boosted pipes are used as grouting pipes to reduce the number of times of piling, which not only improves the construction efficiency, but also reduces the structural disturbance of the soil and the influence of smear effect, thus reducing the impact on the radial permeability and the radial consolidation coefficients. The method does not use geotextile bags for granular materials, which can avoid the problem of forming a localized clogging area around the geotextile bags, and the method not only improves the efficiency of vacuum transfer in a pre-consolidation stage, but also improves the grouting effect in the later stage, effectively enhances the strength of soft soil and makes granular material piles and the surrounding soil form composite ground.
