The failure of dams to hold water for
long periods can prove detrimental as
they form a massive part of our reserved
water resources. Damax Kahn & Kahn’s dam liner
presents an opportunity to sufficiently care for
what is left of our reserved water.
Losing small amounts of water in reservoirs
is inevitable with evaporation taking place
constantly during the hot weather, however
seepage can significantly reduce the amount of
reserved water. Seepage can be a direct result
of human error during construction, such as
the use of unsuitable soil for the dam walls or
poor maintenance.
Damax Kahn & Kahn MD, David Tromp
explains that over time, concrete can crack,
causing considerable water losses. “Repairs
could take up valuable time and cost thousands
of rands not budgeted for. Our PVC liners are an
effective barrier against water loss caused by
seepage and are great for farming, municipal
and industrial applications.”
Damax Kahn & Kahn liners are suitable for
many applications and are guaranteed to make
reservoirs watertight. The drop in liners can be
used to replace damaged ones in steel panel
reservoirs or wire mesh reservoirs.
They have been proven to successfully seal
the cracks quickly without requiring frequent or
close monitoring.
Their effectiveness has been proven through
usage in local municipalities for sewerage works
projects. The product has also been used by a
major petroleum company in its clean-up and
filtration dam and for an agricultural project to
create storage dams for cattle feed.
Manufactured in South Africa, the liner is
made from PVC, which boasts flexibility, a high
level of strength and does not contain any
harmful chemicals which could compromise the
water quality. The liner is available in a standard
3,4 m width, and is supplied in lengths varying
from 80 m to 150 m per roll.
If the liner is damaged, Damax Kahn & Kahn
provides customers with a two-part glue that
can be used to repair any major tears or holes.
In addition, there is a patch kit that works like a
sticker and can even be applied underwater for
any small holes.
Tromp highlights that Damax Kahn & Kahn
can either supply a DIY drop in liner or install the
liner for its clients.
“The liners are installed using specialised
machinery by trained staff who use a combina-
tion of a wedge welder and an extrusion welder.
PREVENT LEAKAGE QUICKLY AND COST-EFFECTIVELY
A decline in the water levels
has left South Africa suffering a
serious water crisis.
Fusing the plastic sheeting is done quickly,
cost-effectively and the liner can last up to 15
years,” he concludes.
