Lotrak® HF550 is a woven polypropylene (PP) geotextile which allows high flow filtration in a wide range of civil engineering applications.

Designed to provide rapid filtration, allowing water to pass into a filter drain without the carriage of fine soil particles, Lotrak® HF550 provides effective filtration for drains and trenches.

Benefits

  • Excellent filtration
  • Optimum drainage capabilities

Main applications

  • Linear drainage trenches
  • Horizontal drainage blankets
  • Fin drains
  • French drains
  • SuDS
