GP® DPC – Gas Resistant DPC is a unique single layer, embossed High-Performance DPC. GP® DPC is specifically designed and manufactured to perform as a Methane, Carbon dioxide, Radon & Moisture resistant damp proof course.

JUTA GP® DPC has an embossed surface to create superior mortar adhesion which is essential when being used in 3+ storey applications. JUTA GP® DPC is compliant to BS EN 14909:2012 and can be used in both vertical and horizontal applications.


Roll weights can be in excess of 5kg and hence appropriate care and equipment is required for unloading and handling.


Rolls of JUTA GP® DPC should be stored on stable/level ground and stacked no more than five rolls high, with no other material stacked on top. The rolls can be stored outdoors when packaged but should be protected from exposure to UV. JUTA GP® DPC is classified as non-hazardous and chemically inert such that it will not react with any acid or alkali environment in which it is used.

JUTA GP® DPC must be installed in accordance with the guidelines laid out in BS8215:1991, BS8000: part 3 and BS 5628. It can be used in most common floor constructions and is installed in a similar manner to damp proof membrane. For external walls, the DPC should be applied 150mm above the adjoining surface and should be linked to a DPM or Gas Resistant DPM in solid floors. The DPC should be applied to a fresh bed of mortar, completely free of projections that may puncture the material or impede the DPC from lying flat.

Jointing and Sealing

Sheets of JUTA GP® DPC must be clean, dry, and free from dirt and grease before application of jointing tape. JUTA GP® DPC may also be heat welded to the underlying Gas resistant membrane.
