Supply and installation of approximately 260Te of Arcelor Mittal GU16N section Sheet Piles, 8.0m to 13.0m long, to form a 215 Lin m Long Permanent Flood Protection Wall bordering existing domestic properties along an existing highway (Beith Road)

Steel Capping and UC waling beams are also to be installed at several service crossings along the length of the sheet pile wall.

All sheet pile interlocks are provided with clutch sealant pre-applied at SP UK’s yard facilities and all interlocks are to receive a 1.0m length of weld on completion for additional flood protection.

On completion of the sheet pile installation the new flood protection wall will be completed with stone cladding and coping.

The ‘U’ section sheet piles are to be installed using our own Giken F201 Silent and Vibration free piles press with a 70Te Telescopic Crawler crane in attendance.

The planning conditions dictated that sheet pile installation works are restricted to the working hours of 10am to 4pm Monday to Friday to limit disturbance to the residents.
