    Certificate type

Juta UK Ltd

High quality gas (carbon dioxide, methane and radon) barrier.

Jump to:
+44 (0)1772 754177 www.juta.co.uk
Application

Ideal for all common ground floor constructions, including:

  • Reinforced cast in-situ (ground-supported) concrete floors.
  • Suspended beam and block concrete floors.
  • Pre-cast concrete slabs.
  • Can also be used above or below the slab (not subject to hydrostatic pressure).

Juta GP1 should be used on any site where carbon dioxide, methane or radon is present up to and including CIRIA 665 SITUATION 6. The barrier is sufficiently resistant to the ingress of harmful gases into a building. On more heavily contaminated sites a passive or active venting system may be required to dilute the gases down to acceptable levels and specific design advice should be sought.

Description

Juta GP1 is a low density reinforced polyethylene (LDPE) ground membrane incorporating an aluminium foil core, suitable for use in areas where carbon dioxide, methane and radon are present in the ground.

Features and benefits:

  • High quality reinforced polyethylene membranes.
  • Low permeability to hydrocarbon and VOC vapours, carbon dioxide, methane and radon.
  • Complies with latest codes of practice as published by the BRE and CIRIA, BS 8485.
  • Independently tested by third party UKAS accredited bodies.
  • BBA approved and CE marked.
