Delivered to South Wales
Cable sand delivered across South Wales
Cardiff, Newport, Swansea, the Valleys and west to Pembrokeshire. National Grid Electricity Distribution, formerly Western Power Distribution, runs the network here, with the same standard as the Midlands: crushed stone dust for bedding and blinding on its own cable work. We supply the stone dust as well as cable sand.

National Grid Electricity Distribution’s rules for the sand
Formerly Western Power Distribution.
- Bedding: crushed limestone dust or crushed granite dust, 3 mm to dust, imported and laid as a bed for the cable or duct.
- Blinding: a further 75 mm of the same over the cable or duct before the warning tape.
- Ducts: bedded and blinded by 75 mm of the same across the full trench width.
National Grid’s standard technique asks for crushed stone dust rather than sand for bedding and blinding. We supply both: crushed limestone or granite dust, 3 mm to dust, and cable sand. Check your drawings and pick the one your job asks for on the form.
