Location of pond
A site investigation before design and construction is important to ensure the pond built is structurally sound and meets regulations, says DairyNZ.
Geotough EPDM, a synthetic rubber membrane, has superior resistance to UV, ozone and weathering, a 50 year performance history and a 20 year warranty.
The product has excellent lay-flat and elongation properties that give it flexibility for laying over difficult substrates. It also passes J-tear tests (ASTM D-624) for easy fixing around protrusions.
The product is made in the US by Carlisle Syntec, who led the development of single ply EPDM in the 1960s; they have since done 200,000 installations adding up to a staggering 1.1 billion m2 of membrane.
Viking Containment can provide a list of approved installation contractors.
