Small components often do the heaviest lifting. Learn how dovetail anchors and ties work, where to use them, and which types are best for long-lasting masonry performance.
What Are Dovetail Anchors and Ties?
In masonry, anchors and ties are metal components that connect a masonry veneer (brick, stone, or block) to the main structural wall — typically concrete or steel. A dovetail anchor system uses a shaped slot (a dovetail slot) embedded in the backup wall so the anchor locks in place and provides excellent pull-out resistance while allowing limited movement.
How Dovetail Anchors and Ties Work
The dovetail system is straightforward: a dovetail slot is cast or embedded into the backup wall, the dovetail anchor slides into that slot during construction, and the tie extends into the cavity to embed in the veneer mortar joint — forming a secure yet flexible connection.
Types of Dovetail Anchors and Ties
- Standard Dovetail Anchors — for typical masonry-to-concrete connections with high shear and tension strength.
- Adjustable Dovetail Ties — allow for multi-dimensional movement; good for seismic or high-movement areas.
- Corrugated & Flat Dovetail Ties — lightweight, easy to install; good for retrofit and light commercial work.
- Stainless Steel Dovetail Anchors — best for exterior or high-moisture environments due to corrosion resistance.
Benefits of Dovetail Anchor Systems
- Exceptional load transfer between veneer and backup wall.
- Allows movement without compromising integrity.
- Durable finishes (galvanized or stainless) resist corrosion.
- Often specified to meet ASTM/structural requirements for veneer anchorage.
Dovetail Anchors vs. Other Anchors
| Feature | Dovetail Anchors & Ties | Wire or Strap Anchors |
|---|---|---|
| Connection Type | Cast-in dovetail slot | Embedded in mortar |
| Strength | High tension & shear | Moderate |
| Movement Flexibility | Excellent | Limited |
| Typical Use | Veneer-to-concrete connections | CMU backup systems |
Installation Tips
- Plan dovetail slot placement before the backup wall is poured.
- Keep slots free of debris so anchors seat fully.
- Use stainless steel in exterior or high-moisture conditions.
- Allow ties to move slightly — avoid rigid bonding.
- Confirm ties are fully embedded into the masonry mortar joint.
