Memtech R1 Reinforced Radon Barrier
Laydex
Memtech R1 radon barrier is a low-density polyethylene membrane reinforced with a polypropylene reinforcing grid. It provides an effective barrier to the passage of liquid water and water vapour from the ground, as well as resistance to underground gases — Memtech R1 is capable of restricting the ingress of radon, methane, and carbon dioxide gases into the building.
It has a high resistance to puncture.
Memtech R1 is a four-layer product, it is red in colour on the top side and black on the bottom side. Suitable for use in areas where carbon dioxide, methane and radon are present in the ground.
