Fields of application

Delta MS8 can be installed economically on horizontal and vertical surfaces as 'permanent formwork' below floor slab, between a subterraneous curtain wall and the structure etc. The dimpled drainage system will drain the ground water and maintain a uniform hydrostatic load throughout the structure.

  • Retaining walls
  • Under floor slabs
  • Drainage layer
  • Protection of underground walls


It is pressure resistant, rot-proof and resistant to saline solutions, inorganic acids, alkalis and liquids such as alcohols, esters, ketones and similar substances.
