FOR SUBSURFACE WATER CONTROL
When erosion of instability of a slope is caused by subsurface water, an Eljen Prefabricated Drainage System will collect and rechannel the flow for disposal.
• Cuspated core prevents damage to permeable fabric.
• 2-Sided core drains both sides.
• Conforms to site irregularities.
• Use any size perforated, corrugated drainage tubing.
• Lightweight materials for safer handling and installation.
• Standard panels: 10'L x 5'H x 3/4"W—custom sizes available.

FOR SURFACE WATER CONTROL
If the source of problem water is at the surface (such as rain runoff) a Reservoir System, which can hold the water until it can be absorbed by the soil, is the perfect solution. Or, add a drainage pipe to the end module to rechannel the excess water. Small, lightweight pre-constructed modules let you build the precise configuration required at any site…in a fraction of the time and effort needed for conventional stone systems.
• 90% Void space for maximum storage capacity and
  runoff control.
• Limited site space required.
• Conform to site irregularities.
• Lightweight materials for safer handling and installation.
• Overlapping fabric flaps leave no gaps for soil intrusion.
• Minimum equipment and personnel required for installation.
