In August 2010 RDL were asked to reline a 10,000m2 lake at the prestigious London Golf Club Heritage course.
Working with a Landscaper chosen by the Golf Club, RDL technical staff ensured the angle and shape of the lake slope was designed to ensure the lake liner was not visible at water level as well as to discourage golfers from walking into the lake to retrieve miss hit golf balls.
Flagon GeoP 1.0mm TPO lake liner was the chosen membrane to use. The superior flexibility and strength of TPO were ideal for the lakes environment .The TPO lake liner membranes none heat absorbing light colour was chosen to ensure the ambient temperature of the water would not promote the growth of algae. This was an ongoing project for RDL as we had previously installed a lake liner to four of the golf clubs other lakes.
Prior to installing the TPO membrane, 400g/m2 of geotextile protective underlay was laid down across the total width and breadth of the lake to ensure the lake liner was protected from sharp stones and ground movement. A number of head walls were constructed to ensure the pipe work leading into the lake was secured and to provide a flanged connection to make the seal water tight.
The lake liner was installed and held in position by running up into an anchor trench which was dug around the lakes perimeter. A section of the lake had a wooden fascia and the liner was installed behind the wooden slats. An anchor trench was positioned beneath the fascia to ensure the lake liner would remain in position. The lining of the lake was completed within four weeks after the ground works had been completed.
