In the mid-1960's, Construction Techniques, Inc. developed and patented the original Fabriform® Fabric Formed Concrete System for soil erosion control. Sixty years later, we continue to manufacture Fabriform to the highest standards of quality.
Fabriform fabric formed concrete is superior to rip rap and concrete paving for several reasons: 1) greater hydraulic efficiency, 2) ability to mitigate uplift forces due to outflow and excess pore water pressure, 3) reduced hydraulic uplift by slowing channel velocities, and 4) reduced potential for underscour by conforming to soil contours.
Fabriform fabric formed concrete is the result of pumping a highly fluid concrete mix into specially woven fabric "envelopes." This method of erosion control allows for fast, economical construction of revetments, landfill containment systems, holding ponds, bridge scour repair, bridge or dock piling reinforcement and countless other applications.
This innovative technique utilizes fabric woven of high tenacity nylon yarn into a variety of forms including mats, pile jackets and bags. At the work site, the custom-made forms are positioned and sewn together with hand-held sewing machines. They are then pumped with fine aggregate concrete and allowed to cure.
Fabric formed concrete eliminates the need for time-consuming wooden forms and expensive lifting equipment and/or cranes. Plus, fabric forms have the unique advantage of allowing the concrete to be pumped and cured below the water line — making site preparation much easier. Labor and material costs are reduced due to simpler installation and more efficient use of concrete. This efficiency makes fabric formed concrete budget-friendly by design.
In addition to economical advantages, Fabriform concrete is the smart choice for soil erosion control because of its high versatility, durability and effectiveness. Worldwide, there are millions of square feet of fabric formed concrete in place.
