Geotextile protective underlay is a hard, permeable material that is purposed to separate, reinforce and protect the primary pond liner from being punctured through rocks or other sharp objects. Geotextile is created from high-quality mechanically bonded polypropylene and is available in different grades of thickness for various application types. Geotextile, as sold through Liners Online is needle punched in the manufacturing procedure to add ‘air’ to the fabric to give it highly effective cushioning properties.

Loads of effort and money are used in building a pond so it is worth the extra spend installing a pond liner protective underlay. The virtue of a pond liner is compromised when installed directly onto the ground because the force exerted by the weight of the water onto the pond liner will push it down onto any rough points in the ground building straining points that may puncture over time. The water scale is one tone per square meter, so that is a load of force pushing down on the pond liner of an average size pond.

Geotextile underlay as well acts as an escape route for any gasses that may build up under a pond liner.

As large ponds are extra than the role of underlay, make sure a sufficient overlap (through 12 to 18 inches) so that any ground movement won’t open the pond liner to any coarse, frigid ground risking a puncture.

In gardens, and pond builds it is essential to lay a protective underlay first. Geotextile is pervious and can fortify and protect all types of pond liners.
At the time of lying over the ground, secure it in place utilizing ground pegs or boulders so it doesn’t slide out of place when installing the pond liner.

Installation of a protective overlay liner| Reason

There are a few cases where protective underlay liner is used on top of the pond liner like around the edge of a pond before the stones or slabs, that will create the border of the pond, are put in its place. Likewise, if your pond displays an underwater shelf or platform for shallow water plants, those areas too should utilize a protective overlay. The presence of an overlay can as well provide some protection against the sharp claws of pet dogs or cats.
Another region that can benefit from a protective pond liner overlay is underneath objects like stone features or plant containers that you include in your pond or when making an attractive pebbled pond floor. Also protecting the pond liner, the textured surface of the fabric will frighten pebbles and other features from sliding about.
