RIW Sheetseal 9000 DPC

RIW Sheetseal 9000 DPC is a high-performance flexible polymeric damp proof course sheet membrane, manufactured from a carefully formulated blend of thermoplastic polymers and additives. It delivers factory-controlled thickness, excellent tensile strength and outstanding elongation at break, combined with excellent low temperature flexibility — making it a dependable choice across a wide range of DPC applications in all seasons and conditions.

Suitable for use in both solid and cavity wall construction, Sheetseal 9000 DPC provides reliable horizontal and vertical moisture control, including stepped configurations. Its flexibility and workability make it well suited for forming cavity trays, lintel trays, sill trays and parapet trays, where precise shaping and reliable water management are essential.

Good to know

• Fully recycable
• Doesnt contain pitch, tar or bitumen
• Durable puncture resistant
  
• Unaffected by extremes of temperature
• All DPC's should be bedded onto fresh mortar, never dry bedded
• The masonry laid over the dpc should also be bedded onto fresh mortar so that the DPC is approximately halfway through the thickness of the mortar joint.
  
• Ground floor level DPC’s in external walls should be laid a minimum of 150mm above the adjacent ground level
• The DPC must be at least as wide as the thickness of the wall. If the DPC is narrower, full protection cannot be achieved and moisture may track up the wall and past the
  DPC
• If joints are required within the material, they must be lapped by a minimum of 100mm, including onto any accessories, and all laps sealed using jointing tape.
