Securing the Pond Liner
Attaching & Fixing the Pond Liner to Walls, Concrete and Decorative Edges
It is essential that the liner is securely fixed to prevent it slipping into the pond. The simplest method for natural ponds, lakes and lagoons is to bury the edges of the pond liner in an anchor trench surrounding the pond. The position and dimensions of the trench are dependent on the size of pond and the stresses on the liner.
Typically, for larger garden ponds the trench should be set back at least 500mm from the edge and it should be approximately 300mm x 300mm.
Decorative Edging Construction
Where the pond 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 pond liner is protected with an additional layer of aquaSHIELD Protective Matting between the liner and the rocks etc.
Weight Secured Construction
In certain situations pond 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 pond 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 – also supplied by Stephens Industries.
