Most parapet failures start with water. Once moisture gets into the masonry, freeze-thaw cycles do the rest. Here's how to protect your wall.
What Coping Stones Do
Coping is the cap on top of the parapet. When it cracks, shifts, or loses its seal, water pours straight into the wall below.
How Water Destroys a Parapet
- Water enters through failed coping joints or cracks
- It freezes in winter, expanding and splitting the masonry
- Mortar erodes, bricks loosen, the wall bows
- Eventually sections can fall to the street
What Prevents It
Sound coping, sealed joints, proper flashing, and functioning drainage keep water out. An annual observation catches early signs before they become expensive repairs.
