The long-established benefits of SikaProof®-A and SikaProof®-P can now go even further with the addition of our loose-laid damp-proofing membrane and gas barrier system – expertly designed for ground-level protection against the ingress of damp and naturally-occurring gases.
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 Gas Barrier is a multi-layer, low-density polyethylene membrane, strengthened by a polypropylene reinforcing grid with an integral aluminium foil.
This damp-proofing membrane and gas barrier is used at ground level to protect the building against moisture, radon, methane and carbon dioxide from the ground.

Standards and Approvals
The Sikaplan®-1650 DPM Gas Barrier is extensively tested to withstand the most aggressive of environments, and is approved to the following standards:
- BS 8485:2015 + A1:2019 – Code of practice for the design of protective measures for methane and carbon dioxide ground gases for new buildings.
- BR211 (2015) – Radon: Protective measures for new buildings.
- Declaration of Performance (DoP)to EN 13967:2012.
- BBA certificate number 20/5738.
Product Installation
We recommend that the Sikaplan®-1650 DPM Gas Barrier is heat-welded by a qualified installer, but taping joints can be used if required. Sikaplan®-1650 DPM Gas Barrier should be overlapped by at least 100mm and always installed in accordance with BS 8485:2015 + A1:2019. Additional influences on the system should also be considered, such as hydrostatic conditions and suitable protection of the membrane itself.

Additional protection
If your project requires additional protection from hydrocarbons and VOCs as well as ground gases we recommend the Sikaplan VOC Membrane range.
