Securing the Liner
It is essential that the liner is securely fixed to prevent it losing its shape or slipping into the lake. The simplest method for natural lakes and lagoons is to bury the edges of the lake liner in an anchor trench surrounding the lake. The position and dimensions of the trench are dependent on the size of lake, and the stresses on the liner. Typically, the trench should be set back at least 500mm from the edge and it should be approximately 300mm x 300mm; as shown in the below image.
Decorative Edging Construction
Where the lake liner is to be hidden by rocks, stones or gravel to produce a more aesthetically pleasing edge detail we would still recommend it is secured in an anchor trench. It is important that the lake liner is protected with an additional layer of Protective Matting between the liner and the rocks etc.
Weight Secured Construction
In certain situations lake liners can be secured with paving slabs or very large stones as long as the weight is sufficient to prevent the liner from slipping.
Vertically Secured Construction
Where the lake liner needs to be fixed to concrete or block walls, it would need to be secured by using special termination battens, and made waterproof by using a water block sealant. These components are available as part of our Accessory range.
