Guarantees
Our guarantees are reputedly the most comprehensive in the roofing market. They are supported by a series of Insurance policies
arranged with first class security in the London Insurance Market. Several different levels of guarantee
are available dependant upon the specific circumstances of the project, the clients requirements, product
choice and period of cover. Icopal guarantees can include the following elements:
• Product failure - including full roof replacement
• Contractor insolvency
• Icopal design
• Consequential damage
• Workmanship
Approved Contractors
Our Guaranteed Roofing Systems are installed by trained IMA and
Team Icopal approved roofing contractors, providing national coverage.
IMA and Team Icopal contractors are trained in all disciplines and vetted
and monitored by Icopal to ensure the highest level of quality and service
are maintained.

System Overview
The PARABIT DUO Hot Melt Waterproofing Membrane is ideal for inverted roof constructions above a concrete substrate where there
is a requirement to achieve a waterproof barrier early on in the construction process.
Substrates
A sufficient bond will be achieved between PARABIT DUO and
a range of suitable substrates, including insitu and precast
structural concrete. The substrate should be uniform and have a
wood float or fine broom finish, prior to being primed to increase
the bond of the membrane. Test bonds should be conducted
before the start of each working area to confirm the suitability of
the substrate to receive the PARABIT DUO membrane. Concretes
with high moisture percentages require a minimum curing period
of 28 days to ensure adequate drying. Alternative Icopal primers
may be required to improve bond strength.

recreational access for public foot traffic.
Plaza / Podium Decks
Many modern buildings incorporate landscaped or paved areas
over basement or subterranean areas such as car parks. These
areas are often used as recreation or circulation space between
buildings. Being roofs they still require a durable waterproofing
system to be installed.
