In 2008, Mid-America Pool Renovation completed a full restoration of the large outdoor swimming pool at Camp Na-Wa-Kwa, a Girl Scouts facility in Poland, Indiana. The pool had previously been shot-creted and plastered, then later retrofitted with a PVC liner as a corrective solution.
After years of use, the PVC liner deteriorated, developing folds, discoloration, pinholes, and tears that led to water loss. Moisture trapped beneath the liner was repeatedly exposed to freeze-thaw cycles, causing significant hidden damage to the underlying plaster and concrete.
The mission was to strip the pool down to its original shot-crete roots, eliminate the moisture-trapping liner, and install a fully-bonded system that could withstand Indiana’s seasonal extremes.
The camp moved away from temporary membranes in favor of the INTER-GLASS® Surface System and comprehensive Crack Repair to fortify the aging structure.
The original choice to use a PVC liner had backfired, as the unbonded sheet allowed water to seep into the subsurface, leading to major structural fractures that went unnoticed for years.
