Verified by manufacturer 6 days ago
BBA Agrément Certificate
Certificate type
High-specification (No Foil) co-extruded multi-layer barrier providing exceptional protection on construction sites contaminated by VOCs, hydrocarbons, and ground gases (radon, methane, CO₂).
Application
- Designed for loose-laid applications, suitable for full ‘line out’ installations or in combination with the Evolution GAS DPC.
- It can be positioned above or below concrete ground floor slabs, above precast suspended segmental ground floor systems such as beam and block floors.
- Provides exceptional protection on construction sites contaminated by volatile organic compounds, hydrocarbons, and ground gases such as methane, radon, and CO₂.
- Conforms to the specification requirements of NHBC Amber 1 and Amber 2 applications.
- Doubles as a damp-proof membrane.
Description
high specification co-extruded multi-layer barrier engineered to provide exceptional protection on construction sites contaminated by volatile organic compounds, hydrocarbons, and ground gases such as methane, radon, and CO₂. Additionally, this high-performance membrane doubles as a damp proof membrane.
Developed with the latest co-extrusion technology, Rhinoplast Evolution uses virgin-grade high-performance engineering polymers, forming a fourteen-layer barrier that incorporates two layers of gas barrier polymer (EVOH) encased in polyethylene outer layers, achieving an overall thickness of 0.4 mm.
This innovative construction provides outstanding robustness and performance without the need for aluminium foil layers or additional reinforcement allowing it to be installed in direct contact with concrete without risk of corrosion while ensuring the highest level of protection against harmful gas ingress.
Features and benefits:
- BBA approved.
- Produced from virgin grade polymers.
- Advanced fourteen-layer barrier.
- Two layers of vapour resistant Ethylene Vinyl Alcohol Co-Polymer (EVOH).
- Single wound to achieve a flat surface.
- CE marked for waterproofing to EN 13967:2012+A1:2017.
- Conforms with BS 8485:2015 + A1:2019 (Table 7).
- Incorporates performance guidance outlined in CIRIA C748.
- Conforms to the specification requirements of NHBC Amber 1 and Amber 2 applications.
- Suitable for all characteristic Gas Situation (CS) ground gas regimes.
- Excellent welding characteristics.
- Fully integrated components, tapes, protection fleece and DPCs available .
