DampSafe 809-HP DPC is a BBA certified, high-performance polymeric DPC which will not extrude under load, up to the point of compressive failure of the wall. It will also not adversely affect the ability of a properly designed and built wall to sustain and transmit compression.

DampSafe 809-HP DPC is compatible with all commonly-used building materials and is suitable for horizontal, vertical and stepped Damp Proof Courses, including cavity trays, in cavity or solid masonry walls, and is also suitable for extending the floor membrane through internal and spine walls within our Newton CDM waterproofing system.

A range of preformed cloaks for continuation of the DPC to internal and external corners are available, as are preformed cloaks for sill tray stop ends, changes in levels, stop ends, joist and beam ends and electrical pattress boxes.

Key Benefits

  • Extremely tough and durable
  • BBA Certified for proven performance
  • Will not deform or extrude under high compressive loads
  • Complete system includes cloaks and accessories
  • Flexible at low temperatures
  • Resistant to shrinkage
  • Effective barrier to water and water vapour
  • Bond of DampSafe 809-HP DPC is greater than the bond between mortar and brick
