Flexural And Shear Strengthening Services
Flexural and Shear Strengthening Contractor
At Gubbi Civil Engineers Limited, we specialise in advanced structural strengthening services tailored for commercial buildings, industrial facilities and multinational corporations (MNCs) across India. With increasing structural demands, ageing infrastructure, and load upgrades, it’s crucial to enhance the flexural strength and shear strength of existing structures. Our expert team offers engineered solutions using cutting-edge techniques like carbon fiber wrapping( CFRP), Carbon laminates, and epoxy mortar.
What is Flexural Strengthening?
The process of improving a structural element’s resistance to bending or drooping loads is known as flexural strengthening. This is crucial for structures that are undergoing:
- Increased load from equipment or redesigns.
- Decreased cross-sectional area as a result of degradation.
- Design flaws or code modifications.
- Making seismic resistance retrofits.
We frequently use steel plate flitching, concrete jacketing- column jacketing, or carbon fiber reinforced polymer laminates (carbon laminates) for column strengthening, beam strengthening, slab strengthening, jetty piles, bridge columns and girders.
What is Shear Strengthening
Shear strengthening enhances a structural member’s resistance to shear or diagonal cracking, which typically occurs near supports or beam-column connections. Shear strengthening is essential for safety because shear failures are abrupt and brittle
- Seismically active zones
- Industrial structures with large spans
- Buildings with poor construction joints or detailing
- RCC structures showing early signs of diagonal cracks
Our techniques include micro-concrete jacketing, steel flitching, FRP anchoring, and Carbon laminates and carbon fiber wrapping systems designed for U-wraps.
Techniques Used by Gubbi Civil
We use a systematic engineering approach for structural strengthening that is customised for the state and needs of your structure. The best methods we use are listed below:
Carbon Fiber Wrapping
Designed and applied carbon fiber wrapping or carbon laminate bonded with high-performance epoxy is known as CFRP wrapping, is one of the most widely used flexural strengthening and shear strengthening techniques.
Advantages
- Lightweight and non-corrosive.
- High tensile strength.
- Minimal section loss.
- Quick installation with minimal downtime.
Carbon Laminate Installation
Carbon Fiber Reinforced Polymer (FRP) – carbon laminates are pre-cured strips of polymer that are specifically utilised to reinforce the flexural integrity of beams and slabs.
Application
- Beam undersides for managing tension.
- Beam undersides for managing tension.
- Cantilevers featuring substantial facade components.
Steel Flitching
We employ steel flitching- steel plated anchored to concrete components in locations where mechanical resistance or fire rating is crucial. This method improves shear and flexural strength.
Best For
- Buildings with heavy industrial use.
- Places where the impact load is high.
- Facilities that require fire-rated reinforcement.
Micro-Concrete Jacketing
To improve the load-bearing capability of beams, columns or shear walls, we strengthen them with micro-concrete jacketing. In this technique, the concrete member is reinforced with new reinforcement steel and then encased with free-flow high-strength Micro concrete. This works well for modifications involving both shear and flexural loads.
Best Suited For
- RCC beams that have visible corrosion.
- Industrial buildings constructed before the present codes.
- In seismic retrofitting efforts, columns.

Frequently Asked Questions
What is the difference between flexural and shear strengthening?
Shear strengthening addresses diagonal or shear failure, whereas flexural strengthening deals with bending resistance. For structural safety, both are essential.
Is carbon fibre wrapping suitable for industrial buildings?
Yes, carbon fiber wrapping is suitable because of its excellent tensile strength, resistance to corrosion, and light weight; it comes highly recommended.
Do you work on residential apartments?
No, Gubbi Civil exclusively works with industrial plants, MNCs, and commercial buildings.
