The difficulty in the successful waterproofing of flat roofs lies in the weak spots on the roof, such as seams in the waterproofing membrane, and difficult to waterproof details such as upstands, outlets and penetrations. Problems can also occur when the waterproofing cannot accommodate fractional movement, which can result in splits and cracks, allowing water ingress. This is where WIDOPAN liquid waterproofing systems come into their own. Once applied, our systems create a seamless, fully bonded membrane that is permanently elastic, yet fully reinforced. Approved for use in ‘zero falls’ situations, WIDOPAN systems can accept continual ponding on the roof, without compromise to the waterproofing membrane. Cold applied and fast curing, WIDOPAN products ensure long-term waterproofing success for your flat roof.
