What do you do when your pool has cracks and spalls and it has to be open is three days? Back in 2001, the City of South Saint Paul, Minnesota had a problem with their new splash pool. Just before opening the pool for its second season, cracks and spalls were discovered in the concrete pool bottom and along corner where the floor meets the wall. The damaged was probably caused by the first Minnesota winter for this neighborhood splash pool facility. The repairs needed to be done fast. The pool was scheduled to be open in just three days. Any delay would be a disappointment for local families and political problem for the City who spent a lot of money to build this water recreation facility.

The call went out to see if anyone could come up with a solution. Roadware Incorporated, also located in the City of South Saint Paul, received a call from the Parks and Recreation Maintenance Department to see if we had any ideas. It turns out, Roadware 10 Minute Concrete Mender™ is a great product for repairing concrete pools.
