Pond liner for a garden pond A pond liner is an impermeable geomembrane used for retention of liquids, including the lining of reservoirs , retention basins , hazardous and nonhazardous surface impoundments, garden ponds and artificial streams in parks and gardens.
The next material surrounding the composite liner would be a leak detection system composed of another material like gravel with an additional geomembrane or complex liner. [4] The geomembranes within the composite liner consist of a high-density polyethylene which provide an effective minimization for flow and deliver and helpful barrier which ...
Ideally, seaming two geomembrane sheets should result in no net loss of tensile strength across the two sheets, and the joined sheets should perform as one single geomembrane sheet. However, due to stress concentrations resulting from the seam geometry, current seaming techniques may result in minor tensile strength and/or elongation loss ...
HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE.

Fabricated geomembranes can be used for a variety of applications including in alphabetical order: aquaculture, baffle curtains, canals, decorative ponds, deicing fluid ponds, drill pad liners for oil and gas development, exposed or floating covers, fertilizer containment, golf course ponds, hydrocarbon containment, landfill liners and covers, mine tailings ponds and heap leach pads ...
Geosynthetic clay liners, or GCLs, are an interesting juxtaposition of polymeric materials and natural soils. They are rolls of factory fabricated thin layers of bentonite clay sandwiched between two geotextiles or bonded to a geomembrane. Structural integrity of the subsequent composite is obtained by needle-punching, stitching or adhesive ...
