ADVERTORIAL Alchimica Building Chemicals providing solutions for over 35 years 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. By Alchimica Building Chemicals | Photos by Alchimica Building Chemicals E 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.
