This concrete service marker block provides a robust and visible solution for identifying the presence of underground utilities. Measuring 300mm x 300mm x 150mm and weighing 32kg, the block is engineered from precast concrete for long-term performance in buried service environments.
Designed to clearly mark the location of electrical cables, high voltage circuits, fibre optic lines, gas and water infrastructure, these markers offer utility providers and contractors a compliant method for service identification and excavation safety.
- Standardised utility messaging - Pre-printed legends enable instant service recognition during site works.
- BS 1881 specification - Concrete marker built to UK performance testing standards.
- Multi-utility compatible - Suitable for marking electricity, fibre, water and gas assets.
- Reliable in all soil types - Maintains visibility and structure in demanding conditions.
- Heavyweight format - 32kg unit resists movement and offers tamper resistance once installed.
Whether marking legacy infrastructure or new-build networks, this concrete marker block is a proven service marker solution. Its flat profile enables easy installation flush with surface levels, reducing trip risk and maintaining a clean site finish. The unit’s mass ensures it remains fixed in position during backfill, traffic load or ground heave.
Each block is cast with high-visibility lettering to clearly state the type of service beneath. Contractors and DNOs use these in housing developments, power corridors, data routes and public realm projects to improve safety and reduce excavation error.
Ideal for installation at inspection points, junctions, and access routes, the marker supports compliance with service marking protocols. It’s also widely used to identify easements and corridor boundaries, providing durable reference for future works or third-party access.
HERMEQ stock a wide-range of Underground Service Protection, Groundworks, Ground Mats & Road Plates conforming to all required safety specifications and regulations.

As a heavy-duty concrete marker, this product provides a long-life solution to underground utility identification and location planning. Manufactured from high-density concrete, the block resists damage from ground movement, vehicle loads, frost and tampering.
Its 32kg weight gives physical presence that ensures the block stays put once embedded, whether installed in open grass, pavement, verge or tarmac. Groundworkers appreciate the predictable form and consistent finish, which makes it suitable for both temporary demarcation and permanent site references.
The high-visibility markings available on each unit help avoid costly and dangerous excavation errors. They reinforce correct digging protocols and give contractors clear surface evidence of what lies beneath. In some projects, the blocks are used in combination with tape, mesh or posts to support a layered protection system.
All marker blocks are cast to BS 1881, ensuring consistency in compressive strength and mix integrity. This level of quality is essential in public-facing spaces where long-term performance is expected, even under repeated physical pressure.
These blocks are a staple across UK groundworks and infrastructure projects, including telecoms, energy, rail and residential sectors. Wherever buried utilities must be recorded and protected, concrete service markers provide a trusted, low-maintenance answer.
