We have partnered with market leaders IKO Permatec waterproofing. IKO Permatec is a tough, flexible, self-sealing membrane. It is suitable for use as the waterproofing layer in most new build flat roofing applications when covered by suitable protection or when used in an inverted or green roof build-up. IKO Permatec is a hot-applied membrane that is manufactured from a specially formulated combination of refined bitumen, synthetic rubbers, fillers, and other additives. It is melted in a purpose-built machine and is applied to a prepared structural deck in two nominal 3mm coats, providing a monolithic waterproofing system.
