DELTA®-RADONSTOP 460: Radon Barrier Membrane

A single-layer membrane for protection against radon gas. Its high surface weight makes it hard-wearing with high UV resistance, so it is particularly suitable for applications with higher loads or longer outdoor exposure times.

Supplied in Ireland by Commons House Design, the official Dörken DELTA® partner in Ireland, with a showroom in Athy, Co Kildare.

Watertightness: passed (2 kPa – 24 h)
Tensile strength: approx. 350/250 N/5 cm
Fire class: Class E
Thickness: approx. 700 µm

Advantages

Hard-wearing
The high surface weight of approx. 460 g/m² makes the membrane robust on site.
High UV resistance
Suitable for longer outdoor exposure before it is covered.
Radon tight
Radon diffusion coefficient below 5.8 x 10-12 m²/s, with a radon tightness test by the University of Prague.
Anti-slip surface
Structured surface on top and bottom.
Wide format
25 m x 4.00 m rolls, folded at 2.00 m, cover large slabs with fewer joints.
Cold flexible
Foldable at low temperatures down to -40 °C.

Where to Use

Install either (1) on the concrete slab or rigid thermal insulation, directly covered by a screed, (2) between the concrete slab and rigid thermal insulation, or (3) on a mineral layer below the floor slab with an additional protective geotextile. Intended use Type A according to EN 13967. Seal overlaps with DELTA®-THENE BAND T 150 or DELTA®-MULTI-BAND M 100, use DELTA®-THENE corners at corners, DELTA®-THAN or DELTA®-TILAXX ULTRA cartridge adhesive, DELTA®-FLEXX-BAND FG 80 around electrical boxes and cables, and DELTA®-FLEXX-BAND FG 150 around pipe penetrations.

Connect to the damp-proof course with DELTA®-PROTEKT or DPC.
