The bags provide the formwork required to cast concrete elements with the mass and stability to withstand the waves and rapidly flowing water. The concrete grout bags may be placed side-by-side or stacked to form an inherently interlocked concrete structure. As with our HYDROCAST® formworks, concrete grout bags can be positioned and filled with concrete from the surface in shallow water or by divers in deeper water.
Since they 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. Unlike rock or precast concrete blocks, they do not require placement by heavy lift cranes working from the land or from barges.
Synthetex’s grout bags can be used to help with the following:
- Breakwater, dike, groin and jetty repair
- Bridge column repair
- Culvert aprons
- Embankment stabilization
- Grout bag underpinning
- Seawall and quay wall repairs
- Scour repairs
- Vertical drains
- Void filling
