Pond & Lake Liner Protection

Lets face it pond liners are expensive, especially the rubber type i.e Butyl Rubber or EPDM pond liners - so ask yourself why spend so much money on an expensive pond liner only to be sold a lightweight / cheap underlay that is not up to the job? A lot of retailers sell pond liners almost at cost price - but make a hugh margin by selling lightweight or inappropriate matting to "protect" the liner.

Can you imagine if a pond is 8.0m x 6.0m x 1.50m deep for example, that is a lot of water / weight on a pond liner and if a lightweight protective underlay was used on top of i.e shale / sharp stones, then over time there is a good possibility the stone will work it way through the geotextile and eventually puncture the liner.

There also may be an occassion that a person might climb into a pond to i.e. separate water lillies - this extra load may also lead to a premature liner failure.

If buying protective underlay / pond fleece / geotextile underlay from an aquatic outlet or online retailer. Here are some general guidelines

• General ground / rough ground - 250gsm / Polyfelt TS60 260gsm protective underlay
• Box Welded Liners / Tailored Liners Polyfelt TS50 200gsm
• Irrigation tank liners 260gsm / 300gsm / 400gsm dependent upon the tank

Polyfelt TS60 260gsm protective underlay, does not require a sand binding for general ponds. In the photo above we used Polyfelt TS60 260gsm protective matting on a pond with rough substrate measuring almost 1900sqm...so it gives you an idea of the strength of the material.

FLP Coir Bio-logs encased with either 5mm heavy duty coir yarn or 2mm polypropylene netting (diamond shaped) with a nominal mesh size of 50mm. The logs are pre-drilled with 25mm diameter holes at a 250mm depth at 16.5cm spacing or 6 per linear meter (18 holes per 3.0m length). Dry roll weight is 9kg's per linear meter or 27kg's per log.

Coir logs are widely used on stream bank, sea shores and lake shores are controlling the sand slide. It is also used in desert areas for controlling sand over come. Coir logs can be cut into sections and stacked for pond,lake or stream bank stabilization, fluid containment, and a multitude of other applications.

FLP offer a wide range of coir rolls,geo-cells and biologs. Made from coir fibre, it is naturally resistant to fungal and bacterial decomposition and is cheaper and environmentally friendly than the usual synthetic geotextiles.

Our coir geotextiles can be used in a variety of applications and solutions including

- Slope stabilisation

- Erosion Control

- Reed Bed & Fitration Sytems

- Sediment Barrier / Silt Barrier

- Contamination containment / Spill Prevention

- Green Roof Sedum Mat / Vegetation Containment

- Swimming Pond / Pond Zoning

- Aquatic Habitat Creation / Bio-engineering
