Crown damage from freeze-thaw cycles
Why it happens here
Water pools on a flat or cracked crown, freezes overnight, and expands. The cycle repeats all winter and breaks the crown apart. Downtown Lawrence gets enough freeze-thaw days to destroy a crown in a few seasons.
Our approach
We rebuild the crown with a proper slope and overhang so water runs off. We use a crown mix designed for freeze-thaw climates. Then we seal it to keep water out.
