A culvert is a transverse and fully enclosed drainage structure that runs under a road or portion of land. The size and type of culvert depend on the amount of water flowing, the area that is discharging to it and how deep the culvert is being installed. Some culverts can also serve as roadway surfaces, but they will always serve to convey water through a pipe or channel. Generally, selection and type of material will depend on the comparative cost, the location of the structure, availability of skilled labor, time limitations and design being proposed.
On every project we consider how to achieve more with less. Techniques such as screening surface soils and recycling aggregate material can reduce the need for transport to and from the site – which not only reduce emissions and resource costs but limit disruption to local residents
