Water & Sludge Containment

Polymeric liners are prone to puncture by inclusions within the underlying soil. Equally, if the liner is to be ballasted by stone on top then there is a further potential for damage. Thick, non-woven geotextiles are the proven solution for dealing with this problem.

• Protection to liners (either or both sides) during installation and in service life
• High puncture resistance at minimum cost
• Narrow widths available for ease of handling (typically 2m wide)

GEOfabrics' geotextiles have been widely used in the maintenance and refurbishment of navigations and waterways owned and managed by British Waterways and the Environment Agency.

Protection beneath a liner

Geotextile selection is dependent on the depth of water, type of liner and subgrade quality/condition. GEOfabrics can help identify the optimum protection geotextile to prevent liner puncture from underlying stone.

Protection above a liner

Often the upper slopes are exposed to damage and it is good practice to cover these areas with a depth of soil which will sustain vegetation. Alternatively, a stone or concrete revetment can be used to achieve a hard landscaped appearance. The geotextile will protect the liner from puncture from this cover whilst also providing a degree of slope stability.

Ornamental lakes, balancing ponds and reservoirs may also require protection above the liner if they are to be ballasted.
