Crown cracks from freeze-thaw cycles
Why it happens here
Franklin Village winters regularly drop below freezing, and water in small crown cracks expands when it freezes. This widens the cracks and lets more water in, leading to liner damage and leaks.
Our approach
We rebuild crowns with flexible refractory cement that withstands freeze-thaw. We also seal the crown and apply water repellent to the brick to reduce water absorption.
