Precast Concrete Marker Blocks help to locate and identify buried service lines. They are part of a range of accessories that may be used in conjunction with access ducting and service protection markers. There are four standard Marker Blocks. Other non-standard specials can be made on a bespoke basis.
The Marker Blocks have lettering formed in the top surface of the units to identify the service it is identifying. Bespoke letters and numerals can be supplied subject to normal minimum quantities.
CG2 and CG3 Marker Blocks have a recess formed in the top face of the unit. This provides the opportunity to attach a supplementary identification plate, if required, using a suitable adhesive.
