During excavation and ground works, accidental damage to buried infrastructure such as fibre optic cables, power cables, gas, water, and district heating pipes represents a major safety and financial risk. Inadequate or unclear marking of underground installations often results in cables and pipes being discovered only after damage has already occurred.
Contractors and utility operators therefore require a clear, physical, and early-warning solution that alerts excavation crews before they reach critical infrastructure. The solution must be durable, easy to install, and adaptable to different types of underground installations and site conditions.
EXPO-NET Warning Nets are designed to provide a highly visible and reliable warning system installed above buried cables and pipes to prevent excavation damage.
The nets feature a unique mesh structure that ensures the excavator teeth catch the net during digging. As a result, parts of the net are pulled up with the bucket and become clearly visible both inside and outside the trench, alerting operators before the underlying infrastructure is reached.
Manufactured from polypropylene (PP), the warning nets are non-degradable and do not release harmful substances into the soil. They are available in a wide range of widths, lengths, and colours corresponding to standard pipe and cable colour codes and can be supplied with printed warning text at one-metre intervals.
For enhanced traceability, the nets can also be supplied with an integrated tracer wire made from acid-proof stainless steel with PP coating, allowing non-metallic cables to be easily located after installation.
The use of EXPO-NET Warning Nets provides a timely and highly visible warning before excavation reaches underground cables or pipes, significantly reducing the risk of damage.
Customers benefit from:
The result is lower overall costs, increased operational reliability, and enhanced protection of critical underground infrastructure throughout its service life.
