What is Structural Repairing?
Restoring Structural Integrity to Ageing Buildings
Over time, RCC structures develop cracks, spalled concrete and corroded reinforcement due to water ingress, carbonation, chloride attack or overloading. Left untreated, these defects weaken the structure and can compromise safety. Structural repairing addresses the root cause — not just the visible symptom.
Devki Projects assesses every structural defect before recommending a repair method — from polymer-modified mortar and micro-concreting to crack injection and carbon fiber strengthening — ensuring the fix addresses the actual cause of deterioration, not just its appearance.

Applications
Where We Do Structural Repairing
Structural repair work is carried out wherever RCC members show signs of cracking, spalling or corrosion.
RCC Column & Beam Repair
Repair of cracked, spalled or corroded columns and beams to restore their intended load-bearing capacity.
Slab Crack Repair
Sealing structural and non-structural cracks in floor and ceiling slabs to prevent further water ingress and deterioration.
Spalling & Concrete Repair
Removal of loose, delaminated concrete and reinstatement with polymer-modified repair mortar or micro-concrete.
Rebar Corrosion Treatment
Exposed steel cleaned, treated with anti-corrosive coating and passivator before being encased in fresh repair mortar.
Building Facade Repair
Repair of external wall cracks, spalled sunshades and chajjas that pose safety risks and affect building aesthetics.
Balcony & Cantilever Repair
Structural repair of balconies and cantilevered slabs showing deflection, cracking or spalling at the underside.
Retaining Wall Repair
Repair of cracked or bulging retaining walls affected by soil pressure, water seepage or inadequate drainage.
Structural Crack Injection
Epoxy or PU resin injected into active or dormant cracks to restore structural bond and prevent water penetration.
How We Work
Our Structural Repair Process
A systematic, diagnosis-first approach to every structural repair job — from assessment to protective finish.
1
Structural Assessment
Visual inspection and, where needed, non-destructive testing to identify the cause and extent of damage.
2
Concrete Removal & Rebar Treatment
Loose, deteriorated concrete removed; exposed rebar cleaned, de-rusted and treated with anti-corrosive coating.
3
Repair Mortar Application
Polymer-modified repair mortar or micro-concrete applied to restore the member's original section and profile.
4
Crack Injection (If Needed)
Active or hairline cracks sealed via epoxy or PU resin injection to restore bond and prevent water ingress.
5
Protective Coating & Curing
Anti-carbonation or protective coating applied over the repaired area, followed by curing and final inspection.
Materials & Methods
Repair Systems We Use
We select the right repair material and method for each defect — based on cause, exposure and structural significance.
Polymer-Modified Repair Mortar
High-strength, shrinkage-compensated mortar for hand-applied repair of spalled columns, beams and slab soffits.
Micro-Concrete
Free-flowing, pourable concrete used for larger-volume or congested reinforcement repair sections.
Epoxy / PU Injection Resin
Low-viscosity resins injected under pressure into cracks to restore structural bond or seal active water paths.
Rebar Corrosion Inhibitor
Passivating coatings applied to cleaned reinforcement bars to halt ongoing corrosion before re-encasing in mortar.
Anti-Corrosive Primer / Coating
Protective anti-carbonation coatings applied over finished repair areas to slow future degradation from the environment.
Carbon Fiber Wrap (CFRP)
Carbon fiber reinforced polymer sheets bonded to columns/beams for additional load-bearing strengthening.
Bonding Agent
Epoxy-based bonding coats applied at the old-to-new concrete interface to ensure a monolithic, durable repair.
Non-Shrink Grout
Precision grouting for base plates, bearing pads and confined repair sections requiring dimensional stability.
Why Choose Us
Why Mumbai Trusts Devki Projects for Structural Repairs
Cosmetic patching that ignores the underlying corrosion or crack cause fails within a year or two. Our team diagnoses the actual defect and applies a repair system engineered to last.
01
Diagnosis Before Treatment
We identify whether damage is from corrosion, water ingress, overloading or age before recommending a fix.
02
Rebar Treatment, Not Just Patching
Exposed steel is always cleaned and treated with anti-corrosive coating — not simply covered over with mortar.
03
Right Material for the Defect
From repair mortar to micro-concrete to CFRP wrapping, we match the material to the structural need, not the lowest cost option.
04
24-Hour Mumbai Response
Structural defects can worsen quickly — our team mobilizes for assessment within 24 hours across Mumbai.
05
Transparent, Fixed Quotations
Pricing based on defect area, severity and repair method. No surprise billing — you know the cost before we begin.
FAQs
Frequently Asked Questions
Common questions about structural repairing services in Mumbai.
How do I know if a crack is structural or just cosmetic?
Structural cracks are typically wider than 3mm, run diagonally across beams/columns, or show signs of active movement (widening over time, visible on both sides of a wall). Cosmetic cracks are usually hairline and confined to plaster. Our free assessment identifies which type you're dealing with before recommending treatment.
What causes rebar corrosion in RCC structures?
Rebar corrosion typically results from water ingress reaching the steel through cracks or inadequate cover, carbonation of the concrete over time, or chloride exposure near coastal areas like Mumbai. Corroded steel expands and causes concrete to spall — which is why treating the rebar, not just patching the surface, is essential.
Is it safe to live in the building while structural repair work is ongoing?
In most cases, yes — repair of individual columns, beams or slab sections doesn't require full building evacuation. However, if the assessment reveals a critical safety concern, we will advise on temporary propping or precautions before work begins.
How long does structural crack injection take?
A typical crack injection job takes 1–2 days per crack, including resin curing time. Larger repair projects involving multiple columns or beams with concrete removal and re-casting can take 1–3 weeks depending on scope.
Do you provide a structural engineer's certificate after repair?
Yes, for structural repairs we provide documentation covering the assessment findings, repair method used and completion details. For society or legal purposes requiring a formal structural stability certificate, we can coordinate with an empanelled structural engineer.
Can old buildings be structurally strengthened rather than demolished?
In many cases, yes. Techniques like column jacketing, CFRP wrapping and comprehensive crack/spalling repair can significantly extend a building's service life. We assess overall structural condition and advise whether repair and strengthening is a viable, cost-effective alternative to redevelopment.
