2. Grout bags

Broadline Construction offer standard 20kg polypropylene bags for deploying grout and sand by divers and ROV. Our unique handles ensure that bags can be easily maneuvered subsea and rapidly placed at the worksite.

Bags can be filled with sand, aggregates or cement to provide different densities and performance subsea. The bags can also be lined with water resistant liners if required to provide longer shelf life and prolonged workability for grout bags once they are deployed subsea. Our bags are load tested and certified by NATA approved 3rd party test facilities
