Maxxon DPM (Damp Proof Membrane)


Maxxon® DPM (Damp Proof Membrane) is a unique 2-component, moisture tolerant, high density, chemically enhanced epoxy product which prevents the passage of water vapor and moisture through concrete floors and walls on or below grade. Maxxon DPM eliminates delamination of adhesives, floor coverings and coatings. Maxxon DPM also prevents capillary infiltration of oil or other chemicals from the ground and can be used to treat oil contaminated slabs.

Maxxon DPM (Damp Proof Membrane)

DPM reduces water vapor transmission levels of up to 25 lbs/24 hrs • 1000 ft2 to 3 lbs or less for the installation of most floor covering systems including VCT, sheet vinyl, carpets, wood, laminates, epoxy, terrazzo and synthetic.
