The Role of Geotextile Membranes in Water Containment Solutions
Friday, June 14, 2013
Basically, where a rubber liner has been installed for any type of water containment such as lakes, reservoirs or potable water storage tanks, a Geotextile Membrane can be used to form a protective barrier. The characteristics of a Geotextile protective underlay membrane
make this a very important material to use in a wide range applications.
Geotextile is a robust, synthetic poly felt material made from polypropylene or polyester and comes in three forms: woven, needle punched or heat bonded. The material is permeable and has, when used in association with soil, the ability to separate, filter, reinforce, protect, or drain. It is resistant to soil acids and alkalis and impervious to fungi or rot.
This type of membrane is very easy and quick to install requiring no specialist tools. Geotexile is a very inexpensive material relative to the returns of not having to carry out repairs on a galvanised steel water tank due to corrosion caused by a leaking tank liner or having to excavate a lake to repair damaged liner.
Russetts Developments (RDL) geotextile membranes
are designed to be rot-proof and permeable to water. For any pond, lake or reservoir project, geotextile is ideal for use when installed below liners providing an excellent level of protection against puncturing from rocks, roots and other soil debris. When installed above it also provides protection against puncture where objects such as soil, gravel, rocks or concrete features are placed on the liner by limiting how much the liner can stretch under pressure.
It is very important that the protective underlay used maintains its condition for the same length of time as the liner for any water containment project. Old carpet, cardboard and other makeshift products will rot, leaving the protection useless and your liner vulnerable to damage long before the end of its guarantee.
Geotextile liners are also well suited for use with horticultural solutions. It is used for moisture conservation, the prevention of weed growth and soil erosion by placing a layer on top of bare soil and then covering it with a mulch. Applied over drainage systems it prevents them getting clogged up with silt and other particles.
RDL offers a range of specialised geotextile protective membranes in addition to TenCate Polyfelt products TS60, TS50 and Cosmotec LPP250M protective underlays.
The geotextile underlay required is dependent on the substrate beneath or on top of the liner, the size of the liner and of course the thickness of the lining material used.
