Geosynthetic clay liner with modified edges for improved sealing

A clay liner is provided for use in constructing low permeability barriers in the bottom of landfills and man-made bodies of water. The liner is provided in the form of a layer of bentonite preferably disposed between a primary carrier sheet and a cover sheet. At least one outer edge of either the cover sheet or the primary carrier sheet is made from a material that allows substantial bentonite migration through or includes a slit that enables bentonite to migrate through while the remaining areas of the cover sheet or primary carrier sheet are fabricated from a fabric that does not permit substantial bentonite migration. When two liners are disposed adjacent to each other in the bottom of the landfill or pond, the two liners are overlapped so that the more open portion of one liner engages the adjacent liner. Upon activation, the bentonite migrates through the more open fabric to create a seal between the two adjacent liners. The result is a self-sealing geosynthetic clay liner system.

Water and/or oil-impermeable sealing mat consisting substantially of a substrate layer, a layer of swellable clay and a cover layer

A water and/or oil-impermeable sealing mat is provided in form of a bentonite non-woven fabric combination with the possibility of transmitting thrust from one batt layer to the other, i.e. on a slope thrust forces can be transmitted by the covering batt material through the layer of swellable clay into the supporting batt material. Such a sealing mat is a fiber-reinforced mineral seal permitting the transmission of thrust forces on slopes, without the risk of the layer of swellable clay itself becoming the preferred sliding plane. The sealing mat consists of a non-woven textile material as substrate layer, a layer of swellable clay, preferably sodium bentonite, and a cover layer consisting preferably also of a non-woven textile material, all three layers having been needled together in the conventional manner in a needle loom. When moistened, the clay swells and forms the water and/or oil-impermeable layer. The water and/or oil-impermeable sealing mat is used especially in hydraulic engineering and in waste disposel engineering.

Filter bed mat - has layers of textile material and sand held in position by needle punching

A filter mat which allows fluid to percolate and provides a closed seal in a filter bed is constructed of textile material in the form of a cushion in layers. This is filled with granular material wrapped in the textile material which retains it. The textile material with the filling, partic. at the edges, are held together by a needling process. ADVANTAGE - Filter beds usually have a deep layer of sand at the base, and some above the filter material. When it is retained as a sheet, the layer of sand is kept level, even, and does not require special equipment to install. It is not disturbed on installation, and sand is not lost around the rim, where a much improved seal is formed. There is a redn. in the amt. of sand.
