High performance bitumen polymer damp-proof course (DPC), available in a range of widths.

Features and benefits:

  • A high bond strength, flexible bitumen polymer DPC, designed to provide high adhesion to mortar.
  • It is a mixture of bitumen, synthetic polymers, synthetic fibres and other additives.
  • Does not extrude under compressive load, under normal working conditions.
  • Robust – resistant to impact damage, under normal working conditions.
  • Durable – will remain effective for the design life of the building, under normal working conditions.
  • The DPC has flexibility and exceptional toughness which can be particularly useful at jambs.
  • Provides horizontal, vertical or stepped DPCs including cavity trays in either solid or cavity walls of brick, block, stone or concrete.
  • The product is supported by a complete range of accessories, is compatible with other Hyload waterproofing products as well as most commonly used construction materials.
