The Culvert Socks from AIRE prevent soil erosion from road embankments by increasing the culverts length and reducing the waters' speed when exiting the sock. By using a Culvert Sock and other runoff prevention products slopes stabilize quickly which allows time for plants to take root in construction disturbed areas. One person can install a Culvert Sock on a steel pipe, plastic culverts or concrete culverts. Need more information? Call us at 800-247-3846.
