Triton’s gas barrier system protects listed almshouses from landfill gas

Tuesday, August 28th, 2012

The listed almshouses are situated just metres from the edge of a landfill site

Triton products, including liquid applied TT Vapour Membrane, were specified to form a ground gas barrier system in the redevelopment of listed almshouses, situated in close proximity to a landfill site. Externally, two coats of TT Vapour Membrane were applied to the entire wall area extending below internal floor level to base of wall/foundation level.    Internally, two coats were applied to the new floor slab. A perforated sub floor drain linked to Triton’s ground gas fan under the new slab.

Fillet Seal was installed to all wall floor junctions, prior to two coats of Triton TT Vapour membrane being applied to the entire floor area, returning up the walls to beyond the new damp proof course.

The works were completed by contractors, R. Lydiard/R. Nicholas.

Triton TT Vapour Membrane is a ready blended coating that acts as a waterproof barrier against Radon, Methane and Carbon Dioxide.  It can be retro-applied to concrete, masonry and brick substrates by airless spray, roller or brush to walls.
