The Next Generation of Storm Water Treatment Technology

Terra-Tubes™ Fiber Filtration Tubes
Terra-Tubes are the industry's most cost effective storm water treatment device designed to effectively trap, filter, and treat sediment-laden runoff while reducing hydraulic energy.

What Are Fiber Filtration Tubes?
Terra-Tubes Fiber Filtration Tubes (FFTs) are engineered composites of wood fibers, man-made fibers and performance-enhancing polymers - all encased in heavy-duty, knitted cylindrical tubes. This revolutionary filtration medium is available as a superior polymer delivery system or as stand alone, high performance fiber tubes to accommodate specific applications including:
  • Slope Interruption Devices (SIDs)
  • Channel/Ditch Flow Checks
  • Bio-Swale/Storm Water Treatment Systems
  • Drain Inlet Protection
  • Perimeter Sediment Control
Terra-Tubes are most beneficial when used as systematic components of a Storm Water Pollution Prevention Plan (SWPPP). They are an ideal complement to other erosion control technologies, such as:
  • Hydraulically Applied Products
  • Erosion Control Blankets (ECBs)
  • Turf Reinforcement Mats (TRMs)

The Keys to Terra-Tubes™ Performance
Terra-Tubes leave wattles, fiber rolls, and similar technologies in the dust. No other product provides Terra-Tubes' three primary functions: flow, filtration, and flocculation. For the best sediment retention and storm water treatment option, turn to the superior technology of Terra-Tubes.
The light, lofty, and resilient composite of thermally fused wood and man-made fibers creates air space and cavities to facilitate flow. Water passes through the engineered matrix, allowing soil particles to become trapped throughout the three-dimensional tube profile. Flow is critical to the filtration process. Without sufficient flow, failure may result from the product being undermined or sediment washing over the top of the filtration system.
Thermally Refined™ wood utilizes intense heat and pressure to create fine fibers designed to maximize surface area and water retention. These, combined with crimped, man-made fibers, generate far greater surface area than the agricultural or horticultural by-products in common fiber rolls. Greater surface area results in greater filtration. The engineered fiber composite is the reason that Terra-Tubes trap more sediment than the closeset competitor - even without the inclusion of flocculating polymers.
Impregnated flocculants are slowly dissolved and released by the kinetic energy of water flowing through the tubes. The flow through process provides a superior polymer delivery system to treat sediment-laden water. The flocculants react with suspended soil particles initiating coagulation and aggregation. The tube's matrix entrains the majority of these coagulated particles, while settling or complementary erosion control devices will aid in the removal of remaining particles.
