Frequently Asked Questions
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.
What is a culvert and its purpose?
A culvert is a drain or tunnel that channels water under an obstruction like a road or railway. Its main purpose is to prevent flooding and erosion by allowing water to pass through freely, protecting the structure above it.
What are the common types of culverts?
Culverts are typically categorized by their shape and the material they’re made from. The most common types include:
Pipe Culverts: Usually circular and made of metal, concrete, or plastic.
Box Culverts: Rectangular structures made of reinforced concrete.
Arch Culverts: Arched structures, often with a natural bottom.
The choice depends on the water flow, cost, and site conditions.
Why do culverts fail and how is it prevented
Culverts typically fail for four main reasons:
Blockage from debris clogging the opening.
Undersizing, which causes water to flow over the road during heavy rain.
Structural collapse from corrosion, damage, or age.
Erosion (scour) at the outlet, which undermines the structure.
Prevention relies on proper design, regular inspections, and routine maintenance, especially clearing away debris.
