Project Description

Salt Fleet Flats

Salt Fleet Flats involved the construction of an environmental habitat approx. 60 hectares in size. It is comprised of an inter-tidal mudflat in an area outside Cooling Marshes on the south bank of the River Thames in Kent.

To enable the environmental habitat to be created a 2.4Km tidal flood embankment was built tying into the existing defences and Econ were contracted to carry out the installation of the erosion protection and construction of a new concrete slipway. The erosion protection involved the installation of approx. 95,000m2 of erosion matting and installation of over 200,000 pins.

Challenges encountered during the works included working near a Salt Fleet water course. This area is a designated Special Protection Area (SPA) and RAMSAR site, which was prone to bird habitats. Mitigating measures were taken throughout the works to reduce our impact on the migrant birds.
