architects and design engineers overcome problems with roof garden
installation, water leakage and root penetration, Dow Hyperlast has introduced
VERDISEAL Green Roof Waterproofing System. Comprised of a primer, elastomeric
membrane and robust wear coat, VERDISEAL balances economic high performance
with flexibility in installation and use.
suitable waterproofing system for garden roofs is a major challenge for
architects and specifiers. With VERDISEAL - thanks to the system’s monolithic,
seamless quality - the design possibilities are unlimited. VERDISEAL can
be easily applied onto complex shapes and adheres evenly to flat and
horizontal surfaces, as well as combinations of levels and
undulations. The 2mm/80 mils-thick seamless membrane keeps the surface
sealed, protecting against water leakage, mineral residue leaching, garden
chemicals and oil spillages, and resisting root penetration. Any damage
can be repaired locally, without removing the whole membrane, to minimize
replacement and disposal costs.
waterproofing system is supplied in liquid form, and, unlike sheet membrane,
cannot be punctured prior to use. It is applied by spray or hand, without
hot bitumen or the need for reinforcing sheets or flashings. The wear coat is
comprised predominantly of renewable resource-based polyol.
Hyperlast, a division of Dow Polyurethanes (PU), a business group of The Dow
Chemical Company, is a leading PU systems house with more than 30 years of
experience in the development of innovative materials, products and solutions
for customers worldwide. Waterproofing products from Dow Hyperlast have
been used in a number of green roof projects around the world.
waterproofing system is just one of a continuing range of products tailored to
specific architectural and engineering applications. It is readily
available through Dow Hyperlast’s trained and certified installers and is
backed by Dow Hyperlast’s extended warranty, subject to terms agreed with
