Old Building
Strengthening

Rescuing aging concrete structures from the inside out. We specialize in internally retrofitting 1 to 5-story hotels and commercial buildings in UP, using heavy metal columns and beams to provide maximum strength while keeping the steel hidden.

Internal Structural Rescue

Saving Weak Concrete Buildings from the Inside

Older hotels and commercial buildings in India are typically constructed on basic concrete and rebar (sariya) foundations. Over time, these buildings begin to weaken, crack, or even lean. Before they reach the point of collapse, Suraj Fabricators provides an internal rescue solution.

Instead of ugly external supports, our expert teams work inside the building. We apply heavy-duty thick metal sections—massive steel columns and I-beams—tightly alongside the internal walls and pillars. By keeping the structural strengthening inside, we ensure the metal remains hidden behind interior finishes, preserving the beautiful exterior look of your hotel while making the building incredibly strong and safe.

Internal Retrofitting Anatomy

The Anatomy of Internal Retrofitting

How exactly do we strengthen a 5-story hotel without destroying its aesthetic appeal? Here is a breakdown of our internal execution process:

Our Approach

The Strengthening Blueprint

Retrofitting requires exact calculations and careful execution to ensure the existing structure is safely supported during upgrades.

Structural Audit & NDT

Comprehensive Non-Destructive Testing (NDT) to assess the current strength of concrete and steel components.

Load Calculation

Advanced structural engineering analysis to determine the exact reinforcement required for new machinery or seismic codes.

Custom Fabrication

Manufacturing precision steel plates, brackets, and jackets in our facility tailored to your building's exact dimensions.

Precision Installation

Expert on-site execution utilizing high-strength epoxy grouts, welding, and wrapping with minimal operational downtime.

Targeted Upgrades

Retrofitting Applications

Internal Metal Column Support UP

Multi-Story Hotel Strengthening

When an old 4 or 5-story hotel building in Uttar Pradesh starts showing structural cracks, completely rebuilding is often not an option. We install a thick steel structural framework entirely from the inside.

This heavy internal metal framework physically holds up the ceiling slabs and takes the load off the weak pillars. Once the steel is installed, it can be easily boxed in with gypsum or wood, completely hiding the retrofitting work while securing the building.

Steel Column Bolting to Concrete

Heavy Section Pillar Jacketing

Old brick and concrete pillars often suffer from 'spalling', where the concrete falls off and exposes rusted sariya inside. We resolve this permanently.

By tightly encasing the old pillar with thick metal sheets and heavy steel angles, we effectively create a brand-new metal pillar around the old one, completely restoring its load-bearing capacity and seismic resilience.

Core Capabilities

Strengthening Techniques

Metal Column Jacketing

Encasing old, cracking concrete pillars with extremely thick steel plates and heavy metal sections to stop them from collapsing under load.

CFRP Wrapping

Application of Carbon Fiber Reinforced Polymers to beams and slabs, providing immense tensile strength without adding dead weight.

Micro-Concreting

Using specialized, high-strength, non-shrink grouts to repair honeycombing, spalled concrete, and reinforce aging structural joints.

Foundation Underpinning

Strengthening the base foundation of a building to support added floors or stabilize structures affected by soil settlement.

Technical Details

Material & Structural Specifications

Successful retrofitting relies entirely on the quality of bonding agents and reinforcement materials. We use only certified, high-performance structural composites and steel grades.

Heavy Metal Sections

We use exceptionally thick IS 2062 Grade steel beams, columns, and channels to physically hold the weight of aging 4-5 story structures.

Structural Adhesives

Heavy-duty epoxy resins and thixotropic grouts used to ensure a perfect monolithic bond between old concrete and new steel.

Carbon Fiber (CFRP)

Ultra-lightweight composite materials offering tensile strength up to 10 times higher than standard steel reinforcement.

Anti-Corrosive Coatings

All exposed steel retrofits are treated with zinc-rich epoxy primers and polyurethane topcoats to prevent future rust degradation.
