While joint separation or shifting is a common form of culvert decay, more severe damage includes collapsed, distorted, and crushed culverts. Let's discuss how to properly repair a crushed culvert. Inspecting a Crushed Culvert. When performing an inspection for a crushed or distorted culvert, structural and hydraulics engineers must:
Lay a Crushed Stone Base. Our experts prefer crushed stone for the base rather than naturally occurring gravel dug from a pit. Crushed stone is a little more expensive. However, it provides better drainage, and because of the sharper angles on the stone, it requires less compacting, and once it's compacted, it stays that way.

Here are some of the best ways to stop culverts from washing away as rain hits and water levels rise: 1. Install the Correct Size Of Culvert. Your culvert will quickly result in substantial soil erosion and blockage if it is too small. The size of the culvert is determined by the volume of water and debris it has to pass to prevent erosion.
