A cold-setting, self-adhesive waterproofing sheet, designed for vertical and horizontal exterior and interior surfaces.


  • Consist of a combination of a four-ply cross-laminated special HDPE sheet and a sealing and adhesive layer of bitumen rubber.
  • Laid straight from the roll, the material safely bridges any cracks in walls or floors.
  • Extremely flexible and protects against driving rain immediately after it has been glued on.


  • No curing or drying time is required, so that protection, drainage, and/ or perimeter insulation layers may be installed and the excavation filled up immediately after Delta®-Thene has been applied.
  • Combined with Delta®-Terraxx protection and drainage sheets, Delta®-Thene forms a complete high-quality waterproofing, protection, and drainage system that can be installed with considerable savings in time.
  • Connections between the material and plastic windows or doors are unproblematic.
  • Any damage caused in the Delta®-Thene layer by subsequent activities may be easily repaired by gluing on a patch.
  • Floor-heating coils or pipes laid out on a Delta®-Thene surface may be held in place with strips cut from the self-adhesive sheet.
  • Connections to most types of plastic damp-proof courses can be made without the need for a primer. However, contact surfaces must always be clean, bitumen-resistant, and free from dust.
