Rothesay Pier Settlement – Phase 2 (Grouting & Piling Works)

Description

Settlement has occurred behind the existing quay wall, specifically to the backfill of the old masonry pier over an approx. length of 120m at Rothesay Pier. The 1st phase of work, completed last year, consisted of the installation of a 5.6m high scour screen along the length to reduce thrust and wave action against the wall and protect and prevent further deterioration of the masonry wall. This contract (Phase 2) aims to address the settlement and prevent sliding failure of the wall by construction of a relieving RC slab supported by 225/559mm piles to the east and west sections, coupled with a grout curtain and mass grout to the central 30m section.
