Flat concrete roofs are typically seen as rooftops for commercial buildings, while
modern day architecture prescribes that flat roofs are also favoured for private homes.

ven though concrete is chosen as a material for its
longevity and a sleek appearance, it is exposed to the
elements 24/7 and 365 days a year. Ultraviolet (UV)
rays, pollution, sea salt spray (at the coast), thermal shock
and rain all affect the structural durability of concrete.
There are a few steps to follow to ensure concrete’s
longevity which include the design, the construction and the
protection of concrete.
All exposed concrete should be protected with a sealer to
prevent moisture and build-up of mould (due to moisture). A
failure to use the right sealer – or to properly apply the sealer
– increases the risk of concrete failure leading to expensive
maintenance, repairs and replacements down the line.
Protecting the concrete with a waterproofing me mbrane
is one way of avoiding damage foccurring earlier than
anticipated that will inevitably help the concrete roof to last
much longer. Liquid applied membreare leading the way in
technology and Alchimica Building Chemicals has provided
solutions worldwide for more than 35 years.
HYPERDESMO ® -HAA is a unique single component
polyurethane liquid membrane, based on the successful
combination of Hyperdesmo and Accelerator 3000 which, for
many years, has provided applicators with a solution for a
fast curing, bubble free thick layer membrane. Due to its
unique formulation, it cures rapidly to form a completely
defect free membrane with excellent mechanical and
elastomeric properties. This product is ideal to use on any
structure exposed to the elements and comes with a 10-year
maintenance free guarantee.
HYPERDESMO is (and has been) used successfully in
several types of applications such as:
• On flat and inclined concrete roofs for exposed and
non-exposed applications
• Over polyurethane insulation foams
• In verandas and balconies, under and over tiles
• In bathrooms, wet rooms and saunas
• Heavy traffic areas such as stadium stands and car parks
