Ceannacroc was one of the first underground power stations to be built in Britain, part of the Great Glen hydro scheme, located on the River Moriston in the Highlands. Moore Concrete provided a precast concrete solution ideal for this type of construction project, especially in an area with limited available access.

Using precast concrete, reduces waste and the length of time on site, and enables stricter quality control measures with curing pre-installation.
Moore Concrete engineers and designers worked closely with their counterparts in Green Highland Renewables, Sinclair & Fairhurst Design Group to ensure the structural design was able to meet the requirements imposed on the weir, including the unit weight limit for site handling, joint and base connection details, and unit or pipe opening sizes to suit the hydraulic parameters of the weir system.
