waterproofing membrane comprising of a thick, tough, high
density polyethylene sheet laminated to 4Kg/m2 of quality
Bentonite granules. The Bentonite used in the manufacture
of Dual Seal is capable of repeated cycles of wetting and
drying without deterioration of its sealing properties and
has a life expectancy measured in thousands of years (BBA
Certified). It has WRAS approval for use with potable water.
Dual Seal has been specifically developed for use as a
high-performance waterproofing membrane to provide
a totally watertight barrier in below ground concrete
construction, including basements, underground car parks,
plant rooms, access tunnels etc. Dual Seal Membrane
can be installed in damp conditions and is, therefore
particularly suitable for use as a roof waterproofing system
for each covered potable water reservoirs.
