Description
Description
Newton CDM 503 is a slim-profile, 3mm-stud cavity drain membrane designed for internal waterproofing where space is at a premium. Despite its low profile, it functions as a high-performance "Type C" waterproofing system, creating an air gap that allows water to depressurize and drain safely to a collection point. It is particularly effective for earth-retained walls, vaulted soffits, and tunnels. Being BBA-certified and guaranteed for 30 years, it provides a reliable, long-term solution for creating dry Grade 3 environments. Its slim design makes it ideal for projects where room dimensions must be maintained as much as possible.
