We supply Cement Bound Sand (CBS) throughout Somerset and into parts of Devon, Dorset, Wiltshire & South Gloucestershire.

Cement Bound Sand (CBS) also known as Stabilised Sand is mainly used for cable installations where a hardened fill for protecting the cable is required

Our CBS is compliant with Energy Network Association Technical Specification (ENA TS) 97-1 and National Grid Technical Specification (NGTS) 3.05.07. Certificates are available on request.

Compliant CBS is used to ensure that a low thermal resistance is given and as a result the material can conduct heat away from the cables that is produced during electricity transmission. The thermal conductivity around the cables is of a known value and will remain consistent for the length of the cable being installed.  This allows the cable the ability to carry the required current and be maintained at the designed capacity.

Can you use any 14:1 sand cement mix

No, as not all materials have the required thermal conductivity. Our CBS is fully compliant so you can order with confidence

We supplied CBS for Hinkley Connection Project where the installation of high-voltage, 400kV cables under the Mendip Hills AONB was undertaken
