Foundation Strengthening & Underpinning

Foundation strengthening addresses inadequate foundation capacity, settlement-related structural distress and additional loading requirements through engineered remedial solutions.

Typical applications: Footing enlargement, RCC foundation jacketing, underpinning, foundation rehabilitation and strengthening for building extensions or load changes.

Concrete Spalling & Deterioration Repairs

Repair of damaged concrete affected by reinforcement corrosion, delamination, cracking, honeycombing and loss of concrete cover using compatible repair mortars, micro-concrete and specified rehabilitation systems.

Typical applications: RCC columns, beams, slabs, balconies, chajjas, parking structures, building facades and industrial concrete structures.

Structural Crack Repair & Injection Grouting

Assessment and repair of structural cracks using appropriate techniques, including epoxy resin injection, crack stitching and engineered repair systems, depending on crack characteristics and underlying causes.

Typical applications: Cracked RCC beams, slabs, columns, structural walls, construction joints and concrete members requiring restoration of structural continuity.

Reinforcement Corrosion Treatment & Protection

Treatment of deteriorated reinforcement through concrete removal, steel cleaning, corrosion assessment, reinforcement replacement or supplementation where required, and application of specified protective systems.

Typical applications: Corrosion-affected RCC members, coastal and moisture-exposed structures, balconies, parking structures, industrial buildings and ageing reinforced concrete buildings.

Structural Rehabilitation for Existing Buildings

Ageing buildings and industrial structures may experience progressive deterioration due to environmental exposure, water ingress, reinforcement corrosion, construction defects, overloading or changes in usage.

Structonix undertakes structural rehabilitation works intended to restore structural performance, address deterioration and improve the serviceability of existing buildings.

Our rehabilitation scope may include:

  • RCC column, beam and slab rehabilitation

  • Repair of deteriorated balconies, chajjas and projections

  • Structural rehabilitation of residential and commercial buildings

  • Repair of industrial RCC structures and equipment foundations

  • Structural modifications and strengthening for revised occupancy or loads

  • Rehabilitation works based on structural audit recommendations

  • Concrete repair and protective treatment to reduce recurring deterioration

Where structural assessment or design certification is required, works are undertaken based on recommendations and drawings from qualified structural engineers.

Frequently Asked Questions – Structural Retrofitting & Strengthening Services

Structural retrofitting involves modifying or strengthening an existing structure to improve its load-carrying capacity, structural performance or resistance to specified actions. It may involve RCC jacketing, CFRP strengthening, steel reinforcement, foundation strengthening or other engineered interventions.

Structural repair focuses on restoring deteriorated or damaged structural components, including concrete spalling, reinforcement corrosion and structural cracks. Structural strengthening involves increasing the load-carrying capacity or improving the performance of existing structural members through methods such as RCC jacketing, CFRP wrapping or steel reinforcement. Many rehabilitation projects require a combination of both approaches.

RCC jacketing may be recommended when existing columns, beams or other structural members have insufficient load-carrying capacity, significant deterioration or require upgrading due to additional loads or revised structural requirements. The need for jacketing is determined through structural assessment and engineering design.

Both methods are effective for specific structural strengthening applications. Carbon fibre reinforced polymer (CFRP) wrapping is lightweight, provides high tensile strength and adds minimal thickness to existing members. RCC jacketing increases the concrete section and reinforcement capacity. The appropriate method depends on structural requirements, existing conditions, available space and engineering recommendations.

Yes. Many existing RCC slabs can be strengthened without complete demolition. Depending on the structural condition and required load capacity, techniques such as carbon fibre laminates, steel plate bonding, additional structural supports or concrete strengthening systems may be used. The appropriate solution is determined through structural assessment.

Yes. Structural cracks in RCC columns, beams and slabs can often be repaired using techniques such as epoxy injection grouting, crack stitching and engineered strengthening systems. However, identifying the underlying cause of cracking is essential before selecting a repair method. Cracks caused by structural movement, settlement or overloading may require additional corrective measures.

Concrete spalling commonly occurs due to reinforcement corrosion, moisture penetration, carbonation, chloride exposure, inadequate concrete cover or poor construction quality. It results in cracking, delamination and detachment of concrete from the structural member. Proper repairs involve removing deteriorated concrete, treating affected reinforcement and restoring the concrete using suitable repair materials.

Yes. Structonix undertakes foundation strengthening and rehabilitation works based on approved structural and geotechnical recommendations. Depending on site conditions, solutions may include footing enlargement, RCC jacketing, underpinning and other engineered strengthening techniques.

A structural assessment is generally required before major structural strengthening or retrofitting works. It helps identify deterioration, assess structural adequacy and determine suitable remedial measures. Depending on the building’s condition and applicable regulations, a formal structural audit, testing and structural design by a qualified structural engineer may be required.

Yes. Certain structural repair and rehabilitation works can be carried out in occupied residential, commercial or industrial buildings with appropriate safety precautions, temporary supports and restricted work areas. However, extensive strengthening works may require temporary evacuation or restricted access to affected portions of the structure.

Yes. Structonix operates through two specialised service verticals: Structural Repairs, Rehabilitation & Strengthening and Waterproofing Systems & Solutions. Where moisture ingress contributes to concrete deterioration or reinforcement corrosion, waterproofing treatments can be coordinated with structural rehabilitation to address both the damage and its underlying causes.
