Maintaining Critical Watercourse Infrastructure in London & The South East
Culvert Cleaning, Inspection, Maintenance & Repair
From emergency culvert cleaning to detailed structural inspections and trenchless repairs, our specialist services are designed to manage and maintain critical watercourse infrastructure.
Expert Culvert Maintenance: Inspection, Cleaning & Repair
Culverts are the hidden arteries of our landscape, protecting vital transport links and preventing catastrophic flooding. The failure of a single culvert can close a motorway, stop a railway, and cause devastating damage. Proactive inspection, cleaning, and repair are not just best practice—they are essential.
Drain 247 delivers a complete lifecycle of culvert maintenance solutions. Our specialist teams combine advanced diagnostic technology with heavy-duty cleaning and trenchless repair capabilities to manage these critical assets for public and private sector clients across London and the South East.
We provide a comprehensive suite of services to ensure the structural integrity and hydraulic efficiency of your culverts.
- Comprehensive Condition Assessments: Utilising advanced CCTV, sonar, and laser profiling to deliver a precise understanding of a culvert’s health.
- Heavy-Duty De-Silting & Cleaning: Employing powerful vacuum tankers and high-volume jetting to remove tonnes of debris and restore full flow.
- Trenchless Culvert Repair & Lining: Offering ‘no-dig’ structural repairs for damaged culverts, minimising disruption and cost.
- Scheduled Maintenance Programmes: Designing proactive inspection and cleaning schedules to prevent asset failure and ensure compliance.
- Emergency Blockage & Flood Response: Providing a 24/7 reactive service to tackle critical blockages and mitigate flood damage.
Advanced Diagnostic & Cleaning Technology
A successful culvert inspection or cleaning operation depends on having the right tools. Our investment in a state-of-the-art fleet gives us the ability to tackle any challenge.
Robust crawler camera units form the backbone of our visual assessments, while specialist float rafts allow us to survey submerged pipes. For engineering-grade analysis, our laser profilers create detailed 3D models to detect subtle deformities.
When it comes to culvert cleaning, our combination JetVac tankers deliver unmatched power, using industrial-strength vacuums to extract heavy debris and high-volume water jets to flush the structure clean.

In-Depth Culvert Condition Inspections
To truly understand a culvert’s state, a visual inspection is paramount. Our OS19X-certified teams deploy the appropriate technology to capture a clear picture of the interior. We generate detailed Wincan reports that map all defects, providing the concrete data needed for effective asset management and to plan for essential culvert maintenance or repairs.
High-Volume Culvert Cleaning & De-Silting
A culvert’s capacity can be drastically reduced by years of accumulated silt, gravel, and vegetation. Our methodical cleaning process restores full hydraulic performance. We utilise powerful vacuum tankers to remove the bulk of material and high-volume jetting to dislodge compacted debris, ensuring the culvert is returned to a full-bore, clean condition.
Structural Culvert Repair & Rehabilitation
Discovering a defect is only half the battle. Our in-house teams are equipped to provide a range of culvert repair solutions to restore structural integrity. We specialise in trenchless ‘no-dig’ methods like CIPP (Cured-in-Place-Pipe) lining, which creates a new, jointless pipe within the existing structure. For localised damage, we can install patch liners. These techniques are faster and more cost-effective than traditional excavation, which we also manage for fully collapsed sections.

Frequently Asked Questions About Culvert Services
What warning signs indicate my culvert is at risk?
Look for water pooling at the entrance (known as ‘ponding’), sinkholes or dips in the ground above, embankment erosion, and any localised flooding after rainfall.
How do you decide how often a culvert needs maintenance?
The frequency of culvert maintenance depends on its age, condition, and the risk it poses. We can help you develop a risk-based inspection schedule, from annually for critical assets to every 5 years for lower-risk structures.
Can you repair a culvert without digging up the road?
Yes, in many cases. Our trenchless culvert repair methods, like CIPP lining, allow us to fix cracks and fractures from within the pipe, avoiding excavation.
What makes culvert cleaning different from drain cleaning?
Culvert cleaning involves removing much heavier and larger volumes of debris (silt, gravel, stone) and requires significantly more powerful, larger-scale equipment like JetVac tankers, compared to standard drain jetting.
