Why choose IKO cold applied liquid waterproofing?

Cold applied liquids form a waterproof layer that prevents water tracking. This eliminates joints and provides continuous protection even at upstands, penetrations and difficult detailing.
The specification and installation process reduces on-site risk and allows work to proceed safely in occupied environments, including schools, healthcare facilities and commercial premises.
The way IKO cold applied liquids are formulated before installation means wet-on-wet applications and quick curing is possible*. This is ideal for projects that require a fast return to service, which is particularly important for refurbishments and busy operational sites.
The membranes adhere to a wide range of materials, including concrete, metal, timber, bituminous membranes, plastics and single ply membranes. This enables flexibility across new build, refurbishment and detailing works.

IKO’s cold applied liquid waterproofing systems hold BBA accreditation, verifying performance and system integrity across flat roofs and associated details (IKO metatech Certificate No. 24/7115 and IKO hybritech Certificate No. 24/7122).

Systems are supported by 20-year materials and workmanship guarantees when installed by IKO-approved contractors.
