Dimpled drainage and protection sheet with integral filtration layer

Sika® Drain-850 Geo is a high density polyethylene (HDPE), heavy duty drainage and protection sheet with 10 mm high dimples on the bottom layer and a bonded geotextile (PP) filtration layer on the top layer.

  • High drainage capacity
  • High mechanical/impact resistance
  • Integral filtration layer
  • Resistant to natural aggressive substances in ground water and soil
  • Suitable for contact with soft water (aggressive to concrete)
  • Can be installed on damp and wet substrates
  • Forms a drainage channel in the space between the structural elements and the backfilling/soil/substrate to allow water to be drained away
