Application

  • Acts as a surface drainage layer in vertical and horizontal applications.
  • Suitable for vertical gas (methane and Radon) drainage when combined with a classical filtration gravel layer underneath the floor slab. The top apertures of the drainage sheet should be covered with a layer of gravel to enable the gas to escape into the ambient air without difficulty.

Description

A high-density polyethylene dimpled sheet.


Features and benefits:

  • Comprises a layer of polypropylene compression-resistant permanent filtration geotextile, laminated to a silver polyethylene (HDPE) drainage sheet with 9 mm-high dimples.
  • The vertical drainage system combines high compressive strength with excellent drainage properties.
  • The integrated geotextile mat filters out suspended soil particles and ensures constant water drain-off through the air gap created by the dimple texturing.
  • The silver surface gives the sheet low emissivity as well as enhancing its heat transition resistance.
  • When applied to perimeter insulation boards, the dimpled sheet provides the necessary insulation from contact with the surrounding soil thanks to its plane reverse face.
  • 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.
