Problem: 

Debris was being caught by the bridge support and creating erosion on the banks reducing the required cover of the petroleum pipes underneath.

​

Solution: 

The north side was done using geotextile Fabric Encasement and has lasted over 25 years.  The south side was done prior to our solution with gabion baskets.  That company later had problems with erosion behind the baskets.  Our solution was 1/3 less the cost for a better solution.
