Ensuring built structures are designed, maintained, and repaired to achieve optimal design-life has never been more important. The exponential value of preventing cracks, damage and rust is hard to put a price to.
Roofs form a critical part of the building envelope as they protect from water penetration, leakages, and damage to both the building and its contents. The quality of roofing affects the functionality of the entire structure, and investing in it at the construction stage and every other stage of a building secures the investment in the building as a whole, and the assets it houses. Roofs also have a great impact on the environment around it, including aesthetics, safety, and comfort.
The impact of structural surfaces on urban heating is also a critical part of choosing the right waterproofing system for all structures.
Waterproofing Roofs – the first line of protection
Paulo de-Castro, EBC National Sales Manager at Master Builders Solutions South Africa, understands synthetic waterproofing more than most, and his specialist knowledge comes from years of practical professional experience. “The most important thing is to first understand the need for waterproofing and the various challenges it poses.”
Synthetic waterproofing is membrane based, and the pre-formed membranes that distinguish Master Builders Solutions’ MasterSeal range have highly specific and valuable properties: Thermoplastic Poly-Olephine (TPO / PVC) pre-formed membranes are made from polymers modified to reduce their specific stiffness. This is achieved by combining elastomers and other monomers in the gas phase (EPR Ethylene Propylene Rubber) and obtaining a flexible polyolefin alloy. These properties are extremely valuable in waterproofing roofs, and sealing dams and other water holding structures.
Masterseal – The ultimate shield
MasterSeal membranes are twin coloured and manufactured by co-extrusion in a single layer. The upper sand grey layer has an extremely high resistance to weathering and ultra violet rays, whilst the lower black layer is resistant to puncturing. The upper layer is also known as the signal layer as it reveals installation problems and damage effectively during installation. It is particularly suitable for flat roofs, complex industrial roofs and green roofs.
TPO and PVC membranes have long a life expectancy and are suitable for ballasted roofs (with and without pedestrian access), inverted roofs, mechanical and fixed system roof gardens, mechanically fixed systems, fully adhered systems, exposed vertical surfaces, complex detailing etc.
It is extremely versatile in its application and can be fully adhered or loosely laid. It can be laid over older, pre-existing waterproofing systems and can be fully exposed or covered. Being UV stable and with a life-expectancy of at least 25 years, TPO membranes can run over expansion joints and is installed rapidly.
