JUTA WP SAM

JUTA WP SAM is a waterproof, self-adhesive membrane. It is a bituminous waterproof sheet, composed of self-adhesive SBS polymer-modified bitumen with an upper surface finish of grey co-extruded polyolefin, and a lower surface fish of siliconised release paper. JUTA QP SAM is used for the waterproofing of underground structures, and to prevent the ingress of RADON.

Product Benefits

  • Complies with latest codes of practice as published by the BRE, CIRIA and BSI (BS 8485:2015
Product Description

Handling

Roll weights can be in excess of 20kg (approx. 33kg/ roll) and hence appropriate care and equipment is required for unloading and handling. This product is non-toxic nor flammable.

Storage

Rolls of JUTA WP SAM should be stored horizontally, and pallets should not be stacked o top of one another.

JUTA WP SAM should be stored in a cool, dry place, and be protected from exposure to rain, sun, heat and cold temperatures prior to installation. Exposure to sunlight for an extended period of time could cause difficulty with the removal of the release film.

Installation

JUTA WP SAM should be installed in accordance with the product installation guidelines. It is recommended that JUTA WP SAM is not applied in temperature below 10° C, in colder weather, the material can be warmed slightly to aid adhesion.

Ground Gas Standards 

There are many different standards and guidance documents that detail how to understand the risk of ground contamination, and design solutions to mitigate these risks. The different documents relate to different ground contamination. Below are some of the key documents to be aware of and refer to:

BS 8485:2015+A1:2019 – Codes of practice for the design of protective measures for methane and carbon dioxide ground gases for new buildings.

  • Ground gases typically found near landfill sites, but can occur from other sources
  • Encourages the use of qualified installers
  • Validation to Ciria C735 is a requirement
  • Additional influences on the system should be considered, such as the hydrostatic conditions, and the likelihood of the source contaminant being in direct contact with the protective measures proposed
JUTA WP SAM

BRE 211:2015 – Guidance on protective measures for new buildings. (RADON)

  • Naturally occurring ground gas. Larger concentrations in the South-West of UK
  • The minimum recommendation is a membrane of 300 micrometres (1200 gauge) polyethylene sheet or equivalent
  • It must be installed with considerable care and protected once installed
  • Taped laps are required
JUTA WP SAM

CIRIA C748:2014 – Guidance on the use of plastic membranes as VOC vapour barriers

CIRIA C682:2009 – VOC Handbook

  • Risk-based approach
  • No quantifiable limits on material performance
  • Testing to ISO 15105-2 and EN 14414/EN 14415
  • 9 main VOC types are tested for
  • Welded laps are required as most tapes are made from bitumen/butyl and are affected by VOCs
JUTA WP SAM

CIRIA C735:2014 – Good practice on testing and verification of protection systems to buildings from hazardous gases

  • Good practice on testing and verification of protection systems to buildings from hazardous gases
  • Check design and detailing is in accordance with site requirements
  • Checks the competency of the installer (NVQ LEVEL 2 minimum)
  • Test integrity of the membrane/barrier system
  • Visual inspection
  • A written report on inspection/testing and sign-off

BS8102:2009 – Code of practice for protection of below ground structures against water from the ground
