Evolution GAS DPC - Gas Resistant Damp-Proof Course (DPC)
Verified by manufacturer 11 days ago
High-specification embossed (No Foil) multi-layer damp-proof course (DPC) specifically developed for use on brownfield and contaminated construction sites.
Application
- Specifically developed for use on brownfield and contaminated construction sites.
- Designed to be sufficiently durable to build into perimeter cavity and load bearing walls as part of a gas barrier membrane system to resist moisture and ground gases, including volatile organic compounds (VOCs), hydrocarbons and others, such as methane, radon and CO₂.
Description
High-specification embossed multi-layer damp-proof course (DPC) specifically developed for use on brownfield and contaminated construction sites.
Designed to be sufficiently durable to build into perimeter cavity and load bearing walls as part of a gas barrier membrane system to resist moisture and ground gases, including volatile organic compounds (VOCs), hydrocarbons and others, such as methane, radon and CO₂.
Feature and benefits:
- Advanced fourteen-layer DPC.
- Contains no hazardous pitch or bitumen.
- Will not extrude under load.
- Two layers of gas vapour resistant ethylene vinyl alcohol co-polymer (EVOH).
- Embossed surface finish.
- Flexible and easy to install on site.
- Provides protection against radon, carbon dioxide, methane, hydrocarbons and VOCs.
- Lap joints can be taped or heat sealed/ welded.
- CE Mark to EN 14909:2012 type A.
- Meets guidance and all recommendations set out in BS 8485:2015 + A1:2019 (Table 7).
- Incorporates guidance outlined in CIRIA C748 for VOC protection.
- Suitable for all characteristic Gas Situation (CS) ground gas regimes.
- Conforms to the specification requirements of NHBC Amber 1 and Amber 2 applications.
- Preformed components and tapes available.
