Delta® Terraxx

What is Delta® Terraxx

Delta® Terraxx is a dimpled sheet with welded geotextile installed externally as a protection cum drainage layer to basement walls and its waterproofing system.

  • External surfaces of walls in contact with the earth
  • Retaining walls, lift pit walls etc.
  • Extensively planted roofs
  • Basements and flat roofs
  • Walkways, flag pavements, gravelled flat roofs, and foundations slabs
  • High compressive strength of 400 kN/m2
  • 9 mm dimples provides high drainage capacity
  • Resists degradation in soil and chemical attack
  • Non-polluting of drinking water
  • Unaffected by saline solutions, acids, alkalines, oil, polar liquids and solvents
  • Rot-proof
  • Excellent temperature range from – 30 °C to + 80 °C
  • Excellent resistance to puncture and decay
  • Guaranteed against degradation for 20 years
  • Outstanding drainage capacity of 3.1 l/s · m under a load of 20 kN/m2
  • Meets EN 13252, DIN 4095 and DIN 18195 requirements
  • Integrated sealing edge for easier laying
  • Installed swiftly and cost-efficiently without any additional excavation work
  • Excellent durability reduces future maintenance costs
  • Permanent-filtration geotextile keeps the dimple structure from silting up
  • Water drainage capacity greater than that of a gravel/chip bed
  • Protects basement-wall waterproofing and perimeter insulation boards from moisture, safeguarding their insulation performance
  • Maximum safety for basements from impounded, seepage, and fissure water
  • Reliably drains off methane gas and radon
  • May be installed at depths of up to 10 m, even in extremely wet environments
  • Forms an extremely robust protection and drainage layer
