Sikaplan 1650 DPM Gas Barrier is a multi-layer, low density polyethylene membrane designed and manufactured to perform as a methane, carbon dioxide, radon ground gas, air and moisture protection system.

Sikaplan®-1650 DPM Gas Barrier can be used in conjunction with SikaProof®-A and SikaProof®-P to continue the gas protection at ground level.

Sikaplan 1650 DPM Detailing Strip is a 300mm wide bituminous gas-proof and damp-proof sheet, composed of self-adhesive SBS polymer modified bitumen and an upper surface finish of aluminium foil, and release film.

Used for gas-proofing and damp-proofing of ground structures where harmful ground gases are anticipated.
