Ground Gases, Radon & other contaminants
TT Vapour Membrane
A ready blended coating that once cured, provides a waterproof Radon, Methane and Carbon Dioxide barrier. Triton TT Vapour Barrier can be retro-applied as a waterproof and gas-proof membrane to concrete, masonry and brick substrates or as an alternative to sheet membranes in new construction. It can be applied by airless spray, roller or brush to walls, floors and soffits.
Available in 5 and 20 litre packs.
TGS-GM500 is a very high quality, single layer membrane that prevents the ingress of Carbon Dioxide and Radon gas. Typical areas of use would include the construction of buildings and dwellings near coalfields, on contaminated industrial sites, landfill and brown field sites. The robust, co-polymer membrane is supplied in 2m and 4m lengths making it very easy to install.
TGS-GM500 complies with NHBC recommendations and, when installed in accordance with the BRE report 414 “Protective measures for housing on gas contaminated land”, provides an effective solution that will also prevent moisture ingress.
A high performance proprietary reinforced gas barrier, that incorporates a 12 micron aluminium foil layer, for maximum protection against ground-borne gases. Triton TGS-HP750 can be used to protect against Hydrocarbon Vapours when not in direct contact with the ground i.e., above block and beam floor design.
The membrane has been specifically designed to conform with the latest guidance documents. Due to its unique composition, the membrane is extremely robust and flexible and therefore, easy to install on site. The membrane also provides protection from damp when placed below the slab and therefore, there is no need to install a separate DPM.

TGS-HCM1000 is a specially engineered, tri-polymer membrane that provides a highly effective barrier against Radon, Methane, Carbon Dioxide and Hydrocarbon gases. Formed as a by-product of decomposing matter, Hydrocarbon gasses are explosive and a build up of these colourless gasses can have devastating consequences. The membrane has very high puncture and tear resistance and is supplied in 20M x 1.3M rolls.
TWS-EX100GM is a self-adhesive membrane designed for use as a barrier against Methane and Radon gases. It also acts as a Type A waterproofing barrier.
The aluminium primary barrier is reinforced and protected by the HDPE film laminated to one side and a robust bitumen rubber compound to the other.
Application should be to dry, smooth and primed surfaces.
It also acts as a Type A waterproofing barrier.
Triton Eco Roof Fan
An energy efficient roof fan designed for Radon gas extraction. Can be used in homes, commercial or public buildings. The fan provides low level continuous ventilation and will extract Radon gas or ventilate an ecological toilet.
Compliant with Building Regulations Parts L1 2010 and F 2010.
TGS-GM500 DS Tape
A double-sided jointing tape for use when installing TGS-GM500 gas barrier. The 50mm x 10m butyl tape has a very low vapour transmission rate and outstanding elongation properties. Should be laid in conjunction with TGS-GM500 Joint Tape. Excellent adhesion qualities.
TGS-GM500 Joint Tape
A single-sided overlap tape for use when installing TGS-GM500 gas barrier. Should be used in conjunction with TGS-GM500 Double Sided tape to create a secondary seal when jointing the membrane. Excellent adhesive properties.
TGS-HCM1000 DS Tape
A double-sided jointing tape for use when installing TGS-HCM1000 gas barrier. Should be laid in conjunction with TGS-HCM1000 Joint Tape. Excellent adhesion qualities.
TGS-HCM1000 Joint Tape
A single-sided overlap tape for use when installing TGS-HCM1000 gas barrier. Should be used in conjunction with TGS-HCM1000 Double Sided Tape to create a secondary seal when jointing the membrane. Excellent adhesive properties.
TGS Top Hats
TGS Top Hats provide an effective seal where a 110mm pipe penetrates a membrane. Easy to install. Made from quality materials. Hose clip included. Base of Top Hat: 280 x 280mm.
Triton Fleece Band
Triton Fleece Band is a reinforcing fabric for use with Triton TT Vapour Membrane and is specifically designed for use within liquid applied waterproofing systems.
Available in 1m x 100m and 300mm x 100m rolls.
TGS-GV25 Gas Venting Mat
A 25mm thick single-sided, geocomposite that provides a void beneath floor slabs which, when connected to air inlets and outlets, allows sufficient air changes to dilute gases to safe concentrations when designed correctly.
Triton LPA/Primer is a ready to use emulsion that can be used as a surface primer for Triton Repair Mortar, Triton Floor Levelling Compound, Triton TT Vapour Membrane and Triton RC.
Available in 5 litre packs.
Triton Radon Sump
A perforated sump to allow for the accumulation of gas prior to venting externally via the Triton Eco Roof Fan. A black, polythelene –preformed chamber, measuring 560mm high x 540mm diameter (at top) x 460mm diameter (base) designed to be located in the floor, finishing flush with the surrounding floor level. Supplied with a structural foam flat lid, which is removable and can accept foot traffic.
