A Practical Guide to Modern Masonry Restoration

Words: Aric Hutchinson, Architectural Representative for Hohmann & Barnard

THE MYTH: Masonry Lasts Forever
It’s strong, yes, but movement, moisture, and time still
take their toll.

Common Causes Why Masonry Fails:
- Differential movement
- Thermal expansion & contraction
- Moisture intrusion & freeze–thaw
- Corrosion of steel
- Settlement & structural creep

Many older walls rely on gravity instead of mechanical connections, and that’s where problems begin.

THE SOLUTION: Modern Restoration Solutions
Today’s go-to fix is stainless steel helical anchors.

Helical Anchor Uses:
- Re-anchor the separated brick
- Stabilize bulging walls
- Reinforce cracks
- Restore structural load paths

Installed discreetly through mortar joints, they’re perfect for historic buildings.

How Helical Anchors Work
Threaded stainless steel fasteners that cut into mortar, brick, CMU, or concrete to create a strong mechanical bond. Once installed, they transfer load from the masonry veneer back to the structural backup, stabilizing the wall while still allowing
controlled movement to accommodate minor shifts over time.

Where To Use Them
- Multi‐Wythe Brick: Reconnect wythes
- Concrete / CMU: Direct embedment
- Metal Stud: Selective restoration support

Crack Stitching
Helical bars installed in mortar joints bridge cracks and prevent further movement, making them almost invisible after repair.
