Culvert Cleaning, Unblocking & Inspections
Years of Experience in Complex Drainage Systems
NRC has extensive knowledge and years of experience in handling complex drainage projects, including the effective cleaning, unblocking and inspections of culverts, across the North West and UK.
What IS A Culvert?
A culvert is an essential infrastructure component designed to facilitate water flow under roads, railways, trails, and other embankments.
They are critical in managing stormwater and preventing flooding by channelling water safely from one side of an obstruction to the other.
Why Culverts Need Regular Maintenance
Culvert Cleaning, Unblocking & Inspections
Regular culvert cleaning ensures water can freely flow through the pipe, help maintain road stability and prevent water damage to the surrounding environment and infrastructure.
Over time, culverts can accumulate debris, sediment, and vegetation, which can obstruct water flow, leading to waterlogging or flooding. Blockages not only compromise the culvert’s efficiency but also pose a risk to the structural integrity of the road or railway above.
Meanwhile inspections reveal any structural damages such as cracks, corrosion, or erosion that may require immediate repair.


Culvert Maintenance Services
Our highly experienced drainage experts are equipped with state-of-the-art tools and techniques to unblock and clean culverts, including high-pressure water jets, as well as precision root and intrusion cutting equipment, vacuum suction machines, CCTV survey cameras and robotic inspection units, and confined space-trained personnel for walk-through inspections.
Culvert Inspections & Culvert Surveys
At NRC we survey culverts of various diameters and constructions, assessing its structural integrity, identifying any damage or blockages, and ensuring it efficiently handles water flow.
Regular CCTV culvert inspections are essential for preventing potential issues like flooding, erosion, and road damage, ensuring both environmental protection and infrastructure safety.
Culvert Cleaning & Unblocking
When cleaning a culvert, of any size, we clear all debris, sediment, and obstructions to restore proper water flow and prevent blockages. Our tankers at NRC are equipped with high-pressure water jets, and various brushes and nozzles, as well as precision root and intrusion cutting equipment, vacuumation suction hoses to break down and clean accumulated materials, silt and debris. In some cases, manual culvert entry may be required for thorough cleaning in larger culverts.
