Culvert & Drainage Infrastructure Problems

Collapsed culvert, blocked outfall, damaged headwall or an old drainage structure causing problems? OddGround helps connect difficult culvert and drainage infrastructure enquiries with relevant specialists.

When Drainage Gets Complicated

Not every drainage problem needs a drain company.

Culverts and larger drainage structures can sit beneath farm tracks, private roads, driveways, fields, estates and commercial land, carrying streams or surface water beneath access routes and embankments.

When one fails, the problem can be much more substantial than a blocked domestic drain.

Pipes can collapse, headwalls can fail, outlets can erode, channels can become overwhelmed and water can begin washing away the surrounding ground or access route.

Older rural properties can also contain drainage infrastructure that has been altered, extended or forgotten over many years, making it difficult to know exactly what is happening underground.

OddGround is designed for these harder-to-place problems.

Scour & Erosion

Fast-moving water around culvert entrances, outlets and embankments can remove supporting ground and destabilise structures.

Understanding The Problem

Why culvert failures can become serious

A culvert may look like a relatively simple pipe or opening, but it forms part of a wider system involving flowing water, surrounding ground, access routes and sometimes substantial embankments.

Water can find another route

If a culvert becomes blocked or loses capacity, water may flow over a road or track, spread across surrounding land or begin cutting a new channel around the structure.

The ground above can become unstable

Damage beneath a road or track is not always obvious from the surface. Loss of material around a pipe or structure can eventually result in depressions, cracking or localised collapse.

Outlets and entrances can deteriorate

Concentrated water flow can scour soil and stone around an inlet or outlet. Over time this can undermine headwalls, expose pipework and damage adjoining banks.

Older culverts can be difficult to understand

Farms, estates and older rural properties sometimes contain stone, brick, concrete or pipe culverts installed at different times. Records may be limited and previous alterations may not be obvious.

Not Sure What You Need?

Tell us what you're seeing.

You don't need to diagnose the culvert yourself. Useful descriptions might be as simple as:

“The road above the culvert is starting to sink.”
“Water is backing up on one side.”
“Part of the culvert has collapsed.”
“The outlet is washing the bank away.”
“It keeps blocking whenever we get heavy rain.”
“We have an old stone culvert and don't know who repairs them.”
