TLS is able to supply & install a wide range
of geosynthetic materials, some of the products
that TLS specialise in are below!
HDPE is an excellent product for large applications that require UV and Ozone resistance, chemical resistance or high-quality installations. Typically used in landfill and mining applications, this product is delivered in large rolls with a width ranging from 7-8m and is heat welded in the field by trained technicians providing a high quality, test certified installation. HDPE offers the most cost effective lining system for large projects. HDPE is available in thicknesses ranging from 0.5mm – 3mm. HDPE Lining materials are a cost effective choice for exposed lining projects. This product is used for landfills, WTP & STP Lagoons, channel lining, bio gas systems and mining applications.
EPDM is a durable geomembrane with proven performance history in exposed applications, such as ponds and lakes, canals, fish stock ponds etc. EPDM exhibits high tensile strength and excellent resistance to punctures, UV radiation, weathering and microbial attack. It is also highly flexible material with a low co-efficient of thermal expansion and contraction, enabling it to lay flat in a wide range of temperatures and terrains thereby conforming well to irregularities in the sub grade. EPDM is manufactured and installed as liners, caps and covers in environmental containment applications worldwide.
Geosynthetic Clay Liner (GCL)
GCLs are a great secondary or supportive layer used in conjunction with the right geomembrane. The use of GCLs and the proper liner can be your solution to sub-grade and leak protection issues. Composite Linings: Geocomposite Clay Liners can completely or partially replace thick, multi lift compacted clay layers in composite landfill liners and caps due to the efficiency of the high swelling natural sodium bentonite clay. HDPE Lining materials are a cost effective choice for exposed lining projects. This product is used for landfills, WTP & STP Lagoons, channel lining, bio gas systems and mining applications.
Non-woven Geotextiles provide excellent stability in civil engineering applications. These products form protective barriers and support underneath and can vent built-up liquids and gases beneath the surface. Non-woven geotextiles are used as a cushion for a geomembrane liner or for subsurface drainage, and in gas venting and drainage systems. A woven geotextile is a planar textile structure produced by interlacing two or more sets of strands at right angles. There are two types of strands: slit films, which are flat; and monofilaments, which are round. Woven slit-film geotextiles are generally preferred for applications where high strength properties are needed and filtration requirements are less critical. These fabrics reduce localised shear failure in weak subsoil conditions and aid construction over soft subsoils. Woven monofilament geotextiles are preferred for applications where both strength and filtration are a concern.
Geonet & Geocomposites
Geonets & Geocomposites function well on cost-effective drainage systems with excellent hydraulic properties. These products, functioning very well on steep slopes, are less expensive and more durable than the common sand and gravel systems.
Geocell is an expandable three-dimensional polyethylene, honeycomb-like structure that provides cost-effective solutions to slope and channel protection, load support and earth retention applications. It is used in landfill cover applications, detention pond protection, dam face protection and channel lining systems. The Geocell system stabilises the selected infill material through confinement of soils in its network of interconnected cells.
