How to Repair a Stone Wall
Frost heave, erosion, and gradual deterioration are all common stone wall problems. Here's how to make the needed repairs to keep your wall looking as good as it did the day you built it.
Many natural factors can damage stone walls. Erosion is the obvious choice, as is frost heave. And even though mortared walls are less subject to erosion because of their footing, but their mortar joints—and the surface of the stones themselves—can crack and take in water, then freeze and split. A damaged wall that doesn't receive timely attention poses a safety hazard.
You may be tempted to replace damaged stone with synthetic stone made from epoxy or cement-based materials. Such imitation stone is less expensive. Though the patches may look good at first, they will become conspicuous with further exposure to the elements and ultimately mar the appearance of the wall.
We'll walk you through common stone wall repairs, including replacing a popped stone, rebuilding a damaged wall, repairing stone mortar joints, and more.
