DOT Concrete Marker Blocks

The range of precast DOT Concrete Marker Blocks are primarily used to aid in the location and identification of electric cables and other utility services that are buried underground. They can also be used to mark boundaries and other reference points.

They are made from precast concrete, manufactured and tested in accordance with BS1881 standards and are available in a range of standard sizes with various legends, details of which are shown in the table below. Where applicable the DOT Concrete Marker Blocks have a recess on the underside which houses a 6mm galvanised bar to enable cable draw ropes or similar to be attached. The standard recess size for identification plates is 100mm x 75mm. Any other requirements can be made to order.
