Base Mattress

Fabric Formwork base mattresses can be made to any size as they are essentially a “box” shape” when grouted, which forms a solid foundation for a subsea structure where conditions are not suitable for the structure to rest as designed on the existing seabed.

The fabric formwork bag can be designed to have sufficient additional height to allow it to fill undulations in the seabed when grouted, and the top surface will still be a table like mattress for the structure to rest on during installation and beyond.

These foundations represent a cost effective alternative to rock dumped foundations or excavated foundations to provide a stable base for the subsea structure.
