Case Study: City of Harper, Kansas Historic Water Standpipe Foundation Stabilization Project
The 125-foot tall and 135,000-gallon standpipe was constructed in 1887 and has been in continuous operation since 1907. The original foundation base is limestone. In the early 1900’s the limestone base was encased in concrete.
Since 2013 the city had been monitoring the rate of deterioration of the foundation in its current state. While no major shifts have occurred, there were signs of the exterior concrete deteriorating.
Lamunyon Dry Out and Foundation Repair was called in to provide a solution. Lamunyon recommended wrapping the concrete base in two layers of 24-inch-wide carbon fiber straps, a horizontal layer followed by a vertical layer, stabilizing the historic structure.
