£180.00 Inc VAT

Twin layered cavity drain membrane for external use, designed to relieve hydrostatic pressure against the structure by managing water to the land drain.

Drainage & Protection Membrane

Triton/CM8 Double Drain isolates and protects the external structure from soil, relieving water pressure with the assistance of a maintainable land drain. Compatible for all construction types, virgin polypropylene fibres bonded with the membrane provide high strength and excellent abrasion resistance.

The dual layers combine drainage and protection of new and existing buildings. The membrane offers quick installation and a robust filtration layer allows backfilling of excavated earth due to a high compressive strength.
