With the Delta MS 500 fire-retardant membrane, it is now possible to specify a Type C cavity drainage membrane that offers not only protection from water or vapour ingress but also protection in the event of fire.
The Delta Fire Retardant range has been manufactured with DELTASAFE, a new innovative fire-retardant property which enables the MS 500 membrane to achieve a Euroclass rating of B-S2, d0 in accordance with EN 13501-1:2018, meaning it is possible to specify a Type C cavity drainage membrane without having to radically alter specifications.
A Type C cavity drainage system is a maintainable basement waterproofing solution suitable for new-build basements, refurbishment and retrofit projects. The Type C system comprises a cavity drain membrane, drainage system, submersible package pump and control system. This type of system is designed to combat water ingress and can be used to habitable grades 1-3 in according to BS 8102:2009.
The Delta fire-retardant Type C cavity drainage system offers complete protection from water or water vapour and fire retardant protection.
