The walls for this bio-retention basin were slip-formed without any reinforcing steel. Immediately after the construction and before any backfill was placed, CFRP was considered as a way to make up for the tensile strength of the missing rebar. Backfill and the other construction activities around the basin continued without the addition of the CFRP.
Then, a few years later after the wall had cracked and started to move, United Structural Systems Bruce Harborth was called out to assess the situation again. At this point a combination of CFRP and tie backs was choosen as a way to stabilize the wall and prevent further movement.
For more information on the project, look for the full case study which will be posted to our website once the project is complete.
