Strip Drain is used where a water collection system is needed or full area drainage coverage is not necessary or practical. It can replace traditional pipe and stone for drainage collection systems. It is a two-part Geocomposite Drainage System consisting of a formed polymeric core covered on all sides with a nonwoven filtration geotextile. The geotextile allows water to pass into the core while restricting the movement of soil particles, which could clog the core. Strip Drain has a marvelous ability to collect large amounts of water without the addition of aggregates for the use of draining surface and near surface ground water. When compared to conventional methods, Strip Drain provides a superior drainage system, at a fraction of the cost, in a fraction of the time and is far less disruptive to surrounding areas.
The polymetric core has its own inherent strength, thus no additional stone is needed to provide strength to the system. The core is then encased in a geotextile fabric which allows water to filter into the collection system, yet restrict major soil intrusion as intended. The Strip Drain has a total open area of 188 in2 per linear foot, which is over 60% open space for water to filtrate into the collection system. This gives it the potential to collect 50x MORE water, or collect the same amount of water 50x FASTER, than a standard perforated pipe over the same period of time.
♦ Horizontal or vertical drainage applications (walls)
♦ Thinner drainage layers than aggregate drainage solutions
♦ Reduced dead loads on structure allowing thinner slabs
♦ High, factory controlled consistent flow capacity
♦ Enhances the performance of structural waterproofing by providing an additional barrier that prevents the majority of the water reaching the liner.
♦ High Puncture resistance
♦ Allows use of lower specification backfill
♦ Relieve external water pressure from buried structures
♦ Highways Bridge abutment and wingwall drainage
♦ Structural drainage on rail projects
♦ Drainage on Green Bridges
♦ Drainage behind retaining walls
♦ Covered reservoir roofs and wall
♦ Tunnel drainage
♦ Roof garden drainage
♦ Relief of uplift pressure beneath tanks, slabs and culverts
♦ Capillary break layer below base slabs
♦ Structural drainage
