As leading specialists in the fabrication of fabric formworks for underwater casting of concrete structures, Synthetex offers engineered solutions such as custom armor units for spillway aprons, bulkheads, tunnel and pipe plugs, and more. Our expertise includes working with nearly every component and material used in concrete formworks today, including high-strength polyester and Kevlar® fabrics and sewing threads, and steel and high tenacity polyester reinforcement cables. With newly expanded manufacturing capabilities, we’re able to offer end-to-end solutions in-house, delivering finished products that are designed and built to perform.
HYDROCAST® fabric formworks provide low-cost in situ concrete alternatives to natural rock and precast concrete where they are not possible or practical. Cast-in-place, concrete armor units and structures eliminate the requirement for heavy lift cranes for placement, where rock riprap and precast concrete blocks may require lifts of tens of thousands of pounds. As with our concrete grout bags, HYDROCAST® can be positioned and filled with concrete from the surface in shallow water or by divers in deeper water. Since the flexible fabric forms are cast-in-place, they intimately adapt to variations in the subgrade or bottom contours. Installations do not require dewatering, a crucial advantage in emergency repair of scour aprons.
