Seismic Retrofit & Earthquake Safety

Foundation Bolting & Anchoring

We install heavy-duty expansion or chemical anchor bolts directly through your home’s wood sill plates into the existing concrete foundation. This secure connection helps prevent the framing from sliding off its footing during seismic shaking.

Cripple Wall Bracing & Shear Panels

We reinforce the short timber walls located between the foundation and the first floor. By securely fastening structural-grade plywood shear panels to these framing studs, we strengthen vulnerable spaces against collapse.

Universal Foundation Plate Upgrades

We deploy specialized framing anchor plates in low-clearance crawlspaces where vertical drilling is restricted. These heavy-duty steel brackets are mounted horizontally to secure the wood framing tightly to the side of the concrete foundation wall.

Hold-Down Hardware Integration

We install high-capacity steel hold-down connectors at critical corner posts and structural framing transitions. These heavy-gauge components anchor the upper floors tightly to the foundation to resist vertical lifting forces.

Soft-Story Structural Reinforcement

We strengthen homes with large ground-floor openings, such as garage doors or expansive windows. We install engineered structural steel frames or heavy-duty shear walls to prevent side-to-side shifting and structural failure.

Floor Joist & Framing Tie-Downs

We secure the upper floor framing system directly to the lower crawlspace plates. We apply structural metal hardware connectors, joist hangers, and continuous strap ties to eliminate weak points across your home's load path.
