Why Use The Newton Cavity Drain Membrane System?

The Newton CDM system does not seek to hold back water pressure. Water is controlled and managed by the depressurisation spaces created by the studs on the membrane. The membranes do more than provide a dry inner skin to separate the wet substrate and dry interior, with the studs acting more like stilts to allow for this natural movement of water rather than a pressure-resisting barrier. The draining of the water away from the system is therefore vitally important, and if designed correctly is the safest method of waterproofing available.

The cavity drain membrane can be used within our Newton Type C waterproofing system that also includes Newton drainage and pumping systems. Please see the Newton Installation Manual for details on fixing and finishing of the product and contact us for specialist support.
