The Problem
A public library had damp carpet in the basement near 15,000 stored books. The library was the only one serving 25,000 residents.
Detection Method
Thermal imaging identified groundwater infiltration at a foundation crack near the storm sewer — not a plumbing leak.
Results
Foundation crack sealed with bentonite injection. Drying took 48 hours with library open throughout. Zero books damaged. $8K saved vs full excavation.
