Non-Ductile Concrete Retrofit Services
Securing Bay Area Concrete Buildings for Seismic Safety
Reinforcing Non-Ductile Concrete for Resilience
Non-ductile concrete buildings, common across the San Francisco Bay Area, were built strong but brittle—lacking the flexibility to bend under earthquake forces. Without upgrades, these structures risk catastrophic failure when the ground shakes. Mulhall Construction specializes in retrofitting non-ductile concrete buildings, adding ductility and strength to prevent collapse. We ensure your property meets modern seismic standards, keeping it safe and functional in our fault-heavy region.

Does Your Building Need a Non-Ductile Concrete Retrofit?
Unsure if your building qualifies? A retrofit may be critical if it matches these traits:
- Built Pre-1970s: Constructed before ductile detailing was required in concrete design codes.
- Rigid Concrete Frames: Structures with columns and beams lacking sufficient steel reinforcement to flex during quakes.
- Bay Area Risk Zones: Properties flagged under local seismic ordinances, like San Francisco’s retrofit mandates, due to high occupancy or location.
If your building fits this profile, it’s likely vulnerable. Contact us for a free assessment to determine its retrofit needs.
Why Choose a Non-Ductile Concrete Retrofit?
Retrofitting non-ductile concrete buildings delivers essential benefits for Bay Area owners facing seismic threats. Here’s why it matters:
- Enhanced Safety: Adding ductility to rigid concrete cuts collapse risk in quakes, protecting lives and property.
- Value Preservation: Prevent severe damage that could tank your building’s value, keeping it viable in the Bay Area market.
- Reduced Liability: Meet seismic codes to avoid fines or legal risks tied to an unsafe structure.
- Insurance Benefits: Retrofitted buildings often earn lower premiums, reflecting their reduced quake vulnerability.
- Operational Stability: A non-ductile building could shut down completely after a quake—retrofits keep it operational, avoiding costly interruptions.
Mulhall Construction turns brittle concrete into a seismic asset.

Our Non-Ductile Concrete Retrofit Process
At Mulhall Construction, we streamline the retrofit process to minimize disruption and maximize safety. Here’s how we bring your building up to seismic standards:
- Evaluation: We analyze your building’s structural drawings to pinpoint any discrepancies or potential conflicts with mechanical, electrical, or plumbing systems, as well as tenant activities. A detailed site visit follows, where we collaborate with engineers through requests for information (RFIs) to resolve any concerns.
- Estimation: Using the refined plans, we develop a comprehensive cost estimate for your retrofit. Our team carefully reviews every detail to identify savings opportunities, ensuring an accurate budget that reduces the need for unexpected adjustments later.
- Construction: We carry out the retrofit with precision, prioritizing minimal interruption to your property’s daily operations. Our experienced crew works efficiently to reinforce your building while keeping your tenants’ comfort and business needs in mind.
