PROTECTIVE COATINGS AND MEMBRANES
Rooftop waterproofing remains one of the crucial points of a building’s waterproofing design. Just like a tiled rooftop on a house, correct waterproofing application and maintenance will keep the residences below dry and water-free.
A membrane needs to be capable of withstanding all environmental elements and provide a long service life. The waterproofing contractor must be qualified, experienced and meet the clients building and budgetary needs.
Membrane types can include flexible polyurethane, thermoplastics, bitumen-based torch-on, acrylics, rubber, lead sheeting, and various board and panel solutions. EPL Waterproof & Structural Solutions work with industry leading product suppliers to provide industry leading answers for any scenario.
There are an almost infinite number of waterproofing products for an equal number of applications. A waterproof membrane is a layer of material applied over a surface which does not allow water to pass though. This water-tight coating can be made of any number of materials some of which are:
* Flexible polyurethane – one of the most common types in today's market. Typically easier to apply and cheaper than alternatives, its warranty life from new should be around 10 years. These materials are used in almost any application from rooftops to under-tile membranes in bathrooms
* Acrylics and Epoxy barriers – A very common membrane. A one or two component membranes in a variety of forms and applications.
* Bitumen-based membranes and torch-on – a bitumen-based membrane which can be rolled or spray applied, and sheet-type torched-on. Bitumen based products have been used in waterproofing for many decades, and its incompatibility with other
more modern materials, and better alternatives have made this material a lesser-used option.
* Thermoplastics and PVCs – a single sheet-type membrane applied and ‘welded’ together. High traffic-ability, easy to repair and high temperature resistance.
* Steels, leads and plastics – often used in older buildings for shower trays, rooftop flashing, window surrounds, etc
Some of the applications of membranes are:
* High rise and residential rooftops
* Commercial factories and Civil structures
* Water tanks and reservoirs
* Water features and waterfalls
* Planter boxes & rooftop gardens
* Retaining walls
* Bathrooms, laundries and wet areas
