Subsea Grout Bags used for pipeline supports manufactured by Synthetex are currently in fabrication for a project off the coast of Gabon, Africa. These fabric formwork units are 0.55 meter in thickness and constructed from our 140 kN/m (800 lb/in) tensile strength fabric. Sewn seam strength is increased by incorporating a propietary sewing thread. Each fabric unit will incorporate securing straps. Additionally, concrete filled bag will have a filling valve consisting of a flange and 2-inch female camlock. The divers will attached the male camlock to the fabric units for ease of filling with concrete underwater. To relieve the water from the unit, a water relief valve will be incorporated into each pipeline support bag.
