Sports Pitch Drainage

When used in sports field drainage Pozidrain offers many advantages over traditional pipe and gravel systems. It is compatible with natural turf or synthetic grass sport pitch surfaces and provides drainage, separation, reinforcement and capping in one product.

Pozidrain consists of a high performance single cuspated HDPE core with a geotextile filter thermally bonded on both sides to form a highly efficient drainage layer that offers a sustainable, easy to transport and light-weight alternative to traditional aggregate drainage.

Installation

Where additional seam integrity of adjoining rolls is important, sheets of Pozidrain SKL can be installed, with the flat selvedge of the core overlapped and sealed with double sided Abseal butyl tape.

Typical applications

  • Synthetic & natural grass sports pitch drainage system
  • Separation between backfill material and sub-formation
  • The tensile strength of Pozidrain provides reinforcement to help control differential settlement across the playing surface.

Benefits

  • Pozidrain offers high flow capacity that exceeds the flow performance of a 400mm layer of typical drainage stone.
  • Pozidrain filter fabric pore size is designed to prevent clogging and provide reliable long term performance.
  • Impermeable HDPE core practically prevents water from percolating through to the sub-formation.
  • Improved CBR of the sub-formation for a more stable and consistent playing surface.
  • Pozidrain is supplied in large 4.4m x 100m rolls for rapid installation across large areas.
  • Replaces the requirement for trench and pipe drainage systems, accelerating the construction programme.
