Description

High-density polyethylene (HDPE) dimpled sheeting with a high drainage capacity and compressive strength, suitable for high performance seepage layers in building and civil engineering construction.

Features:

  • A high-density, clear polyethylene (HDPE) drainage sheet with 8 mm dimple height.
  • The vertical drainage system combines high compressive strength with excellent drainage properties.
  • May be installed as permanent shuttering either horizontally or vertically between a shotcrete wall and/ or curtain wall and the concrete wall of the building. In this case, the shotcrete acts as a filter, keeping the seepage layer free from soil particles.
  • It can also be used to upgrade damp and defective floors and is suitable to take a range of floor finishes.

Technical data:

  • Conforms to CE requirements and those of BS EN 13252, Certificate No. 0799-CPD-13.
  • Drainage rate: Approximately 2.25 L/s per metre.
  • Compressive strength (transient loading): Approximately 250 kN/m².
  • Compressive strength (permanent loading): Approximately 90 kN/m².
  • Installation depth (maximum): 10 m.
  • Service temperature range: -30°C to +80°C.
  • Delta® dimpled sheets are rot-proof, resisting saline solutions, inorganic acids, alkalines, and polar liquids.
  • They are proof against attack or modification by any of the minerals, humic acids, and bacterial catabolic products that naturally occur in the soil, as well as by bacteria, fungi, and micro-organisms.
  • The response of all sheet types to soil or underground water is completely neutral, nor will they leach any harmful and/ or ecologically doubtful substances.
  • Care should be taken to ensure that they are not permanently exposed to UV radiation.
