Radon, Air & Moisture Protection System
Membranes
RAC, Reflex Super, RMB400, RMB350 and Necoseal are loose laid radon resisting membranes made from a blend of virgin low density polyethylene (LDPE). When used in a new building as part of the Necoflex RAM™ system, they provide an effective barrier to the passage of radon, air and moisture from the underlying soil. RAC and Reflex Super can also be used to exclude volatile organic compounds (VOCs) from underground storage tanks, or the range of gases from landfill sites such as methane and CO². RAC, Reflex Super, RMB400 and RMB350 have multi-filament polyester reinforcement. RAC and Reflex Super have an additional layer of aluminium foil.
APPLICATION GUIDANCE
See table 2 in NSAI Agrément Certificate 09/0328
Easi-Load™ Radon DPC has been designed using thermoplastic co-polymer technology to give effective protection where a radon, air and moisture seal must pass through masonry walls. It is particularly suitable for cavity wall construction and can be used at all floor/wall junctions. As well as offering high radon, air and moisture vapour resistance, Easi-Load™ Radon DPC also has a high tear strength, will not extrude under load and provides excellent mortar adhesion. It is available in various widths ranging from 100 to 1000mm, and rolls are 20m in length. Ends should be overlapped by 100mm and sealed using a single strip of Monobond RT 30mm tape.
Accessories
Monobond RT™ is a double-sided radon resisting butyl sealant tape designed for sealing joints in RAC, Reflex Super, RMB400, RMB350 radon resisting membranes, and Easi-load™ Radon DPC. Rolls are 30mm x 30m, are blue in colour with light brown release paper which bear the product name.
Necobond™ is a double-sided radon resisting butyl sealant tape designed for sealing joints in Necoseal radon resisting membrane. It can also be used to bond Necoseal to Easi-load™ Radon DPC. Rolls are 30mm x 30m, are buff/orange in colour with white release paper.
Easi-Load™ Radon Corner Assembly has been developed to provide a fast and effective radon, air and moisture seal in traditionally difficult to seal corners. The assembly comprises 3 pieces, each carefully pre-formed from Low Density Polyethylene (LDPE), without seams or joints, in factory controlled conditions. Its unique design makes it suitable for sealing various upstand heights ranging from 100 to 225mm, and a specially developed, pre-applied sealant strip, provides radon, air and moisture protection while accommodating construction settlement up to 8mm.
Easi-Pour™ Liquid Radon Sealant is a two-component bitumen and polyurethane based liquid sealant. It is pourable, self-levelling and provides effective radon, air and and moisture sealing aroud service penetrations, structural columns and irregular profiles of any shape or diameter. Easi-Pour™ is supplied in a special 10 litre double-lid bucket and contains 5.4 kgs. of sealant and and 0.6kg of hardener. Once cured, a custom-made seal is formed. Easi-pour™ will remain flexible and has a life cycle of at least 50 years.
Monarflex® Top Hat is a one-piece, vacuum-formed LDPE collar designed to seal 110mm diamater pipes. In some circumstances it may not be possible to fit the collar over a pipe, if for example there is a socket or bend at the critical point when the pipe penetrates the radon membrane. In these situations, Easi-Pour™ Liquid Radon Sealant should be used.
Easi-Flash™ Self Adhesive Radon Flashing is a multi-purpose radon, air and moisture sealing tape designed for use around thresholds, door end-stops, services, structural penetrations and can also be used to carry out fast and effective radon membrane repairs. It has a bituminous self-adhesive layer on one side and a polyethylene backing on the other. Easi-Flash™ has excellent initial grab (tack) and is highly malleable making it particularly suitable for a wide range of difficult sealing requirements. Rolls are 1.5mm x 300mm x 10m, and have a white PE permanent backing with Easi-Flash™ logo.
