Used to direct water into box culverts or under 3-sided bridges, wing walls can also act as a retaining wall to prevent erosion. Along with headwalls and aprons, this combination of products makes for a long-lasting and easy to maintain stream crossing or way to divert an overflow of stormwater.
Once the culvert is in place, the wing walls are installed at either end and on each side of the opening. Flared out from the opening to direct more water into the box culvert, wing walls prevent the earth around the culverts from washing away as well.
