RIW Cementjoint

An advanced, elastomeric, highly tear resistant, breathable, waterproof composite tape. It is impermeable to water under 10 bar hydrostatic pressure, yet allows the free passage of water vapour.

Features and benefits:

• Permanently elastomeric composite membrane embedded in backing fabric, exhibiting over 600% elongation.
• Good UV and weathering resistance and highly resistant to a wide range of chemicals.
• When embedded in RIW Cementflex, it gives a highly flexible, impermeable seal over ‘live’ cracks and expansion/ construction joints.
