EPDM Pond Liner 3.8m wide – buy per lineal metre

This is simply the best type of pond and reservoir lining material available. EPDM rubber has several significant advantages over traditional pond lining materials.

In order to calculate the size of liner you need, there are two ways to do this. First, if you have a flexible tape measure such as a tailors measure or appropriate outdoor tape measure of similar type, then simply drape your measure through the pond from one side to the other and one end to the other. Allow an extra 200mm on each edge for the liner to be secured. Then take these two measurements and multiply them together. eg, if you have 4.1m one way and 5.8m the other way, then you should allow 4.5m (4.1m plus 200mm each edge for securing) x 6.2m(5.8m plus 200mm each edge for securing) and when multiplied together this makes 28 square metres.

Second, if you have a rigid tape measure such as a typical builders or home handyman type then you need to take three measurements, the length (L) at ground level, the width (W) at ground level and the depth (D) from ground level to the deepest point in the pond. To get your measurements simply allow (2 x D + L) for one measure and (2 x D +W) for the other. One measurement then needs to be rounded up to the nearest roll width. For example if your pond is 4m x 6m at ground level and 2m deep, then your calculation would be 8M (2 x D + L) x 10M (2 x 2M +6M). 8M x 10M = Round the 10M up to 11.4 so 8 x 11.4 = 91.2 square metres of material required.
