Following a competitive tender process, NCS were selected to rehabilitate, waterproof and stabilise a 1.2 km stretch of a concrete lined channel. The works involved the reinstatement of approximately 19 km of joints between concrete slabs, over 3 km of crack repairs and the stabilisation of a number of slabs that were subject to movement.

Due to the extent of cracking in the substrate, it became evident that standard repair methods would not be insufficient. At stage 1 of the works in 2018, NCS proposed an innovative application which would leave a strong and impermeable repair.

The latest round of works saw National Concrete Solutions carry out stage two of the works which comprised of a further 2,000 lineal metres of crack repairs and concrete spalling using a variety of systems including cementitious repair mortars as well as a specialised polyurethane based protective coating.
