Rother Tidal Walls East Case Study- Use of a spider excavator with a remote track machine for piling

The Rother Tidal Walls East project in Rye, Kent, involves raising existing embankments for 6.5km along the River Rother to increase flood protection. Most of the embankment raising is achieved by adding clay to the crest and landward side of the existing profile. However, a 300m section called King’s Avenue has limited space for construction and no space at all for widening the embankment.
Instead, a 5m-deep steel sheet pile wall will be installed through the embankment crest using, for the first time, a "spider" excavator to install the piles and overcome the site's constraints and challenges.
