Dow Hyperlast Launches Assured Waterproofing System for Green Roofs
To help 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.
Choosing a 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.
VERDISEAL 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.
Dow 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.
VERDISEAL 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 approved applicators.
