In a statement, the Public Works Ministry said the project will contribute to “beach stabilization” and the “retention of sediment” drifting in a westerly direction along the Kingston to Kitty foreshore.

The Sea and River Defence, Force Account Unit within the Works Services Group (WSG) is currently responsible for undertaking the installation.

According to the ministry, geotextile tubes are used internationally as a cost-effective material alternative for coastal and marine projects. It said the tubes are manufactured from geosynthetic-based materials which are factory sewn to achieve the desired formation. Installation of the tubes is carried out by filling with sand or suitable dredged material.For the groynes being installed at Kingston, white sand is being utilised as the fill material, it added.
