Radon Barrier Protection Strategy - Necoflex

Radon Barrier Membrane Selection

Seal the main floor areas using any one of 5 Monarflex membranes. Simply choose the membrane best suited to the project site conditions. Installation is extremely fast since the membrane is rolled out like a carpet and taped to the Radon DPC.

Radon Barrier Membrane Selector

RAC

Monarflex RAC - Radon Barrier Membrane

 

Composition: Heavy-duty reinforced LDPE radon barrier membrane incorporating 6 layers (including reinforcement and aluminium foil layer).
Resistance: Very high resistance to radon gas.
Suitability:

Suitable for contaminated sites where volatile organic compounds (VOCs), hydrocarbons (HC's) and landfill gases exist e.g. methane and CO2 – contact Necoflex for specific guidance.

Suitable for use under heavily reinforced concrete slabs, ground beams and pile caps where an increased risk of damage exists.

If selecting Monarflex RAC for its superior gas resisting performance, it is recommended that Alumite Gas DPC is used instead of Easi-Load DPC to ensure consistency.

Foot Traffic: Can handle heavy foot traffic and certain site machinery.

Reflex Super

Monarflex Reflex Super - Radon Barrier Membrane

 

Composition: Robust reinforced radon barrier membrane incorporating 6 layers (including reinforcement and aluminium foil layer).
Resistance: Very high resistance to radon gas.
Suitability: Suitable for contaminated sites where volatile organic compounds (VOCs) and landfill gases exist e.g. methane and CO2 – contact Necoflex for specific guidance.

Particularly suitable for medium to large floor areas where an increased risk of damage exists.

If selecting Monarflex Reflex Super for itssuperior gas resisting performance, it is recommended that Alumite Gas DPC is used instead of Easi-Load DPC to ensure consistency.
Foot Traffic: Can handle moderate to heavy foot traffic – both outer layers made from blown LDPE

RMB400

Monarflex RMB400 - Radon Barrier Membrane

 

 

Composition: Robust extra reinforced radon barrier membrane incorporating 4 layers.
Resistance: High resistance to radon gas.
Suitability:

Particularly suitable for medium to large floor areas where an increased risk of damage exists.
Protective layer advised before concrete pour.

Foot Traffic: Can handle moderate to heavy foot traffic – both outer layers made from blown LDPE blend which gives excellent resistance to abrasion.
Specification:

RMB350

Monarflex RMB350 - Radon Barrier Membrane

 

Composition: Reinforced radon barrier membrane incorporating 4 layers.
Resistance: High resistance to radon gas.
Suitability: Particularly suitable for small to medium floor areas where insulation or other protective layer is placed shortly after membrane is fitted.

Protective layer required before concrete pour.
Foot Traffic: Can handle moderate foot traffic – lower outer layer of blown LDPE blend.
Specification:

WordModel Specification 

 

Necoseal

Necoseal - Radon Barrier Membrane

 

Composition: Single layer of virgin-blend LDPE.
Resistance: High resistance to radon gas.
Suitability: Particularly suitable for buildings with small footprints where insulation or other protective layer is placed immediately after membrane is fitted – the risk of damage is therefore reduced.
Foot Traffic: Can handle light foot traffic (as required for installation).
Specification:
