Coronation Parade, Folkestone, Kent

The Coronation Parade promenade and breakwater in Folkestone, Kent was built in the late 1930s. It consists of 91 reinforced concrete arches and promenade with a retaining wall to the rear. After many years exposed in the harsh sea environment the structure had begun to fail, sections of the concrete had started spalling and corrosion was eating away at the steel reinforcement contained within the concrete. The local council contracted a specialist company to carry out comprehensive concrete repairs and at the same time install into each arch of the structure a corrosion protection system. Diamond Edge Drilling Ltd were called in by the concrete repairs contractor to carry out all of the drilling and chasing required for the installation of the system anodes and cabling. The main elements of our work included but were not limited to:

  • 1360 No. 40mm diameter holes drilled 2.4 to 3 metres deep into the arch walls.
  • 700 No. 40mm diameter holes drilled 2.4 to 3.2 metres deep into the rear retaining wall.
  • 2720 No. 40mm diameter holes drilled into the promenade deck.
  • 6000 linear metres of channelling chased into the promenade deck.

During the course of the contract, Diamond Edge Drilling Ltd worked in close co-operation with the main contractor and the other trades on site to ensure fluent operations where contractor activities inevitably crossed. Our work was completed on programme despite being at the mercy of the elements!
