Delta FM 2.0m x 20m – Floor Damp Proof Membrane 40m2

Delta FM is a waterproof and vapour proof ultra low profile membrane for use on floors above ground.

This premium quality waterproof membrane has an 3.5mm stud to provide a low build up damp proofing layer, allowing the effective isolation of dampness and contamination from the floor finishes.

Delta FM comes in a 40m2 roll making it great value for the damp proofing of floor slabs.


Delta FM is primarily used to damp proof floors above ground, to provide a damp proof barrier to floors without increasing the moisture content of the slab.

Delta FM can be used:

  • To damp proof damp or contaminated floor slabs above ground,
  • To isolate moisture sensitive floor coverings such as timber floor boards from damp and contaminated floor slabs.
  • In listed or historic buildings where a reversible damp proof system is required.
  • To extend a cavity drainage membrane to provide protection to solid basement stairs.


Delta FM is installed stud side facing the floor. Joints in the Delta FM are sealed using Delta Tape and Delta Corner Strip.

Delta FM can be linked to other Delta MS membranes.

A fast-track application, which allows for various floor finishes to be achieved with zero down time.

    We use this whenever we fit solid oak flooring over an old concrete slab. Stops any problems with damp and humidity from warping the board.

    Large order came when we requested.
