ADVERTORIAL Providing protective solutions worldwide for over 35 years Even though concrete is chosen as a material for its longevity and sleek appearance, it is exposed to the harsh elements 24/7 and 365 days a year. By Alchimica Building Chemicals | All photos by Alchimica Building Chemicals A lthough flat concrete roofs are typically seen as rooftops for commercial buildings, with modern day architecture flat roofs are very common for private homes. UV, pollution, sea salt spray (in coastal areas), thermal shock and rain all affect the structural durability of concrete. There are a few steps to be followed to ensure longevity of the concrete namely design, construction and protection. All exposed concrete should be protected with a sealant to prevent moisture and build-up of mould due to any moisture. A failure to use the right sealant, or to properly apply the sealant, increases the risk of concrete failure leading to expensive maintenance, repair and replacement down the line. Protecting the concrete with a waterproofing membrane is one way of avoiding damage from occurring earlier than anticipated and will inevitably help the concrete roof to last a lot longer. Liquid-applied membranes are 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, which throughout the years, has provided applicators with a solution for a fast curing, bubble-free thick layer membranes. 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 for use on any structure exposed to the elements and comes with a 10-year maintenance free guarantee. HYPERDESMO has successfully been used in several types of applications as follows: • In 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 • Hard traffic areas such as stadium stands and car parks.
