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).


Description

JUTA GP2 is a low density reinforced polyethylene (LDPE) ground membrane suitable for use in areas where radon is 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.


JUTA GP2 should be used on any site where low levels of ground gas is present up to and including CIRIA 665 SITUATION 2. 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.
