IKO Permatec Hot Melt Waterproofing System has been specified and installed onto the roofs of three residential apartment blocks in South East London.
The versatile and durable system was applied onto 1,500m2 of roof area at Orchard Lodge – a new housing complex developed by Fairview New Homes Ltd on the outskirts of the city centre. Essex-based contractors, Contour Roofing Ltd, undertook months of planning as well as product training with IKO to ensure its team was confident in the quality and safe application of the hot melt system. Despite specifying other IKO PLC products previously, this was the first time they had used this particular waterproofing solution.
Solution and Installation
Firstly, Contour Roofing Ltd applied IKO Permascreed to the cambered pre-cast concrete planks on the roof areas. Designed to provide drainage falls, IKO Permascreed also offers a stable base for the specified waterproofing system. A purpose-built 18 tonne hot charge transporter delivered IKO Permascreed direct to the site ready for use.
The flexibility and fast drying times of the IKO Permascreed System was ideal for this new build project, as a quick installation was vital to ensure internal trades could access the new apartments to complete their works so they were ready on time for the new residents.
Then, the first coat of IKO Permatec was applied, followed by a reinforcement layer before the second coat of IKO Permatec was installed.
An IKO enertherm EPS Insulation layer was also used, which is suitable for use on green roofs and A+ rated in the BRE Green Guide. Coupled with IKO Permascreed Mastic Asphalt Levelling Solution, IKO Permatec Waterproofing System formed the ideal base for a sedum green roof finish, which was supplied and installed by Sky-Garden.
Jonathan Woods, managing director at Contour Roofing (Essex) Ltd, said: “The success of this project goes far beyond the installation of a quality product on site, but also the months and long hours of planning and health and safety training to ensure we were fully verified and qualified in installing this quality hot melt solution.
Thanks to this hard work and training, we now have full confidence in both the IKO Permatec Waterproofing System and IKO Permascreed Mastic Asphalt levelling solution and are able to deliver to the highest standards of quality, and most importantly, safety.”
