Launching The New Memtech R1 Reinforced Radon Membrane

It’s with great pleasure to introduce to you our new Radon Barrier Memtech R1. This is the most significant product we have taken to the market in a very long time.

Memtech R1 is a Reinforced Radon Membrane exclusively supplied by Laydex Ltd and possesses NSAI and BBA Certification and comes as the main component in a Gas Resistant system which also incorporates a Top Hat, Radon Tape, Gas Resistant Self Adhesive Tape, Radon Sump and all other ancillary items when required.

Memtech now offers a clear and competitive alternative; it can now be specified by Architects, installed in accordance with the Certification but most significantly from your point of interest will give you an alternative Radon System which will be fully supported by Laydex Technical expertise.

Check-out below a few examples of installation, and feel free to CONTACT US for any technical details or specs.
