Free span correction grout bags are highly durable engineered grout bags made of woven fabrics, specially designed for pipeline free span rectification, pipeline protection, and subsea structure stabilization. The grout bags are installed at a specific interval along the length of pipe, providing interim support to the pipe spanning, prevent overstressing of the pipe.
Grout bags are prefabricated according to design requirements and can be easily installed onsite, either by divers or ROV. Once they are fixed into position, cement grout is pumped in-situ, filling the bags and raising the pipeline into desired elevation.
