Our Earthquake Retrofitting Services

We handle the full scope of a retrofit project not just the reinforcement work because getting the assessment and design right is what determines whether the construction actually solves the problem.

Types of Retrofitting We Handle

•        Column and beam jacketing: wrapping existing RCC members with additional reinforcement and a new layer of concrete or steel, without changing the building's footprint

•        Shear wall addition: new reinforced concrete walls at strategic locations to improve resistance to sideways seismic force

•        Wire mesh and plaster reinforcement: a widely used, affordable method for older brick or stone masonry buildings

•        Foundation strengthening: underpinning or widening an undersized or poorly detailed foundation

•        Tie-beam and corner reinforcement: horizontal tie beams and reinforced corners that hold a masonry structure together as one unit

•        Non-structural bracing: anchoring water tanks, tall furniture, and loose parapets or chimneys to reduce injury risk

•        Full building retrofitting: a comprehensive combination of structural and non-structural work for buildings with multiple deficiencies

•        Commercial and school building retrofitting: larger-scale projects with more detailed structural analysis given higher occupancy

Our Working Process

•        Consultation: you describe your concern, whether it's an old house, visible cracks, or a general safety question

•        Site visit: our team inspects wall type, visible cracking patterns, foundation condition, and any signs of prior structural distress

•        Vulnerability assessment: we identify the specific weaknesses in the structure rather than treating every building the same way

•        Structural analysis and design: our engineer designs the retrofit approach best suited to the building

•        Cost estimate: a written estimate covering labor, materials, and expected timeline, before any work begins

•        Municipality approval: where the scope requires structural sign-off, we prepare and submit the necessary documentation

•        Retrofit construction: work proceeds according to the design, sequenced so the building stays stable throughout

•        Quality inspection: completed work is checked against the retrofit design and engineering specifications

•        Final handover: you receive documentation of the assessment findings and completed retrofit work

Materials & Options

The right retrofit method depends on the construction type and the specific weaknesses the assessment identifies.

•        Reinforcement steel and concrete grade: determines the added strength of jacketed columns and beams, matched to the engineering design

•        Wire mesh and cement plaster: the standard, cost-effective strengthening option for older brick or stone masonry walls

•        Shear wall concrete specification: graded to carry the additional lateral load the design calls for

•        Foundation underpinning materials: chosen based on soil condition and the extent of strengthening required

•        Anchoring and bracing hardware: used for non-structural elements like water tanks, parapets, and tall fixtures

Benefits of Choosing Our Service

Life safety: a retrofitted structure is meaningfully better equipped to protect the people inside during a moderate-to-strong earthquake.

Retrofitting is usually far less expensive than demolishing and rebuilding a house from scratch.

It lets your family stay in a home and neighborhood you already know, rather than starting over on a new property.

Documentation value: a completed assessment and retrofit becomes useful later for insurance conversations, reassuring a future buyer, or before adding another floor.

Common Problems We Solve

•        Old, unreinforced construction: houses built before seismic detailing was standard practice

•        Visible cracking in walls: particularly diagonal cracks near door and window openings

•        Post-earthquake uncertainty: buildings that survived 2015 but were never professionally inspected afterward

•        Planned floor additions: on a structure that hasn't been checked for its current load capacity

•        Bank or insurance requirements: asking for documentation of a building's structural condition

•        Unreinforced masonry risk: addressed through wire mesh and plaster reinforcement suited to brick and stone structures

Cost Factors

We don't quote a flat rate upfront retrofitting cost depends heavily on what the assessment finds, and two houses of similar size can need very different levels of intervention. These are the factors that move the number:

A structure with multiple deficiencies and difficult access costs meaningfully more than a straightforward single-issue fix. An accurate number only comes from a site assessment, followed by a written estimate before any work begins.

Why Construction Sewa

Verified professionals: every engineer and contractor connected through Construction Sewa is vetted before being matched to your retrofit project.

Structural expertise: retrofitting only works if the assessment correctly identifies the actual weaknesses; we start there, not with a generic fix.

Quality workmanship: from jacketing to wire mesh reinforcement, the same crew standards apply regardless of project size.

Transparent pricing: a written estimate after the site visit, not a verbal number that shifts once work begins.

Project management: we coordinate assessment, design, approvals, and construction so you're not managing multiple vendors separately.

Timely completion: work is scheduled with milestone-based payments tied to actual progress.

Customer support: reach us by phone or WhatsApp throughout the project.

Workmanship warranty terms depend on the specific retrofit scope and are confirmed in your project agreement after the site inspection.

Share your location when booking a site visit, and we'll match you with professionals familiar with your area's building conditions and local approval requirements.

Frequently Asked Questions

What is earthquake retrofitting, exactly?

It's the process of strengthening a building that's already standing so it can better resist earthquake shaking. Retrofitting works within and around the existing structure, adding elements like column jacketing, shear walls, or wire mesh reinforcement to fix specific weaknesses.

How do I know if my house needs retrofitting?

A few warning signs are worth taking seriously: diagonal cracks in walls or near openings, a house built before current seismic codes were widely enforced, visible tilting or uneven settling, or a structure that went through the 2015 earthquake without a professional inspection afterward. A structural assessment gives you a definite answer.

Is retrofitting cheaper than rebuilding?

In most cases, yes, since you're strengthening the existing structure rather than demolishing and starting over. The exception is when the structure has deteriorated so badly that its foundation and core elements can't reasonably be salvaged. A structural assessment tells you which situation you're in.

Do I need municipality approval for retrofitting work?

It depends on the scope. Retrofitting that changes the structural system significantly, such as adding shear walls or jacketing columns, typically needs engineering approval and often a revised permit. Cosmetic or non-structural work usually doesn't. We confirm what your specific project needs during the approval assistance step.

Can any masonry house be retrofitted with wire mesh reinforcement?

Most brick and stone masonry buildings are good candidates, but the assessment confirms whether wire mesh alone is sufficient or whether it needs to be combined with tie-beam and corner reinforcement or foundation work.

Ready to Get Your Building Assessed?

If you're unsure whether your house needs strengthening, the right next step is a site visit not a guess based on how the building has held up so far. Our team will inspect the structure, walk you through what we find, and give you a written estimate before you commit to anything. Finishing and restoration work after the retrofit, including repainting, can be matched through our texture and decorative paint service.
