Reinforced Radon Barriers
Memtech Low-density polyethylene membrane
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 block on the bottom side. Suitable for use in areas where carbon dioxide, methane and radon are present in the ground.
Best puncture resistance: 1040 N
Reinforced with a polypropylene reinforcing grid
Best radon permeability on the market: 4.3 x 10-12m2/s
Tensile strength: MD 500 / CD 470 (N/50mm)
