One stop shop for design and build.

Clarke Underground offers a turn key operation from the initial stages of scoping and design through the civil installation process, cable installation/fibre splicing/commissioning and finally as-built plans with handover. Our capabilities include all types of underground construction techniques and associated construction works specialising in directional drilling. For large diameter, on-grade, deep river crossing projects, we have a working relationship with Universal Underground Ltd from Cambridge.
