Spray-liquid-applied roof waterproofing system Coniroof 2103 and hand-applied system Coniroof 2150, from Degussa Construction Chemicals (UK) have been awarded European Technical Approvals (ETAs) by the DIBT (German Institute for Civil Engineering), following rigorous testing across a range of performance requirements, valid in all European Economic Area countries for a five-year period.
The systems are based on the use of epoxy resin/polyurethane preparation coatings, combined with polyurethane-based waterproofing membranes and surface coatings. A solvent-free monolithic membrane, it can either be sprayed or hand-applied, Coniroof is guaranteed to perform for up to 25 years and has been designed to provide high-performance waterproofing protection in severe climate conditions. According to Degussa, it sets in just 30 seconds, forming a solid impervious monolithic membrane with no laps to provide weak points for water ingress.
Unlike traditional built-up roofing felts and single-ply membranes, Coniroof conforms to irregular surfaces without needing to be lapped, welded or seamed. This, Degussa claims, makes detailing work up to 20 times faster than with traditional roofing methods, as complex detailing work can be done at the same time as the main roof area. The fast spray-application technology requires no hot works, it adds, and Coniroof's fast setting time enables up to 750m 2 a day of the waterproof membrane to be installed, including detailing.
Coniroof is being marketed for built up roofing systems, overlay systems, podium decks, roof gardens and inverted roofs and is hailed by Degussa as 'the ultimate solution' for walkway and balcony applications.
