Notes
Since PVC is degraded by sunlight; it requires being covered
with a minimum of 12" (1 foot) of clean fill to function as
designed. In prolonged exposure to sunlight, PVC must be
covered before warranted for lifespan. In buried applications, PVC
can provide a service life of over 20 years.
Slopes
should be limited to 3:1, and cover soils should be walked in from
the bottom of the pond to the top, always keeping a minimum of 12"
of clean soil between your equipment and the membrane.
For
larger ponds and lakes, consideration for erosion and wave action
should be taken into account. The use of rip-rap, concrete shore
protection or synthetic erosion control protection is highly recommended.
