Culverts under driveways and roads that pass water safely, sized and set with headwalls and stone so crossings stay put.
A driveway that crosses a ditch needs a pipe underneath it. When the pipe is too small, too shallow or set at the wrong slope, the crossing washes out in the first big storm. A culvert is a simple structure, but one that fails in a very visible and expensive way.
We size and install culverts of corrugated metal, plastic or concrete. The ditch is shaped, the pipe is bedded and set to the right slope, and the ends are protected with stone or headwalls so water does not undercut them. Gravel or pavement goes back over the pipe in compacted layers, with enough cover to carry vehicles.
A culvert must pass the water that reaches it in heavy rain. The right diameter depends on the drainage area, and an undersized pipe will back up and overtop the road.
A culvert needs enough soil over it and compaction in the right layers. Too little cover or loose fill lets the pipe crush or the road sink.
The inlet and outlet are where erosion starts. Headwalls, riprap and shaped ditches protect them and keep the crossing from slowly washing away.
After heavy rain, walk the crossing and check the ends for debris and erosion. Clearing a clogged inlet early protects the road from overtopping.

If the culvert is in a public right of way or affects a regulated stream, permits often apply. Check with your city, county or road department.
It depends on drainage area, slope and local standards. We recommend a size and note when an engineer should confirm it.
Yes. We remove the old pipe, rebuild the bed and install a new one with proper ends.
Sometimes. Boring can avoid cutting a road, depending on size and soil.
Keep the inlet and outlet clear of debris and repair erosion at the ends promptly.
