Concrete Repair Contractor

Concrete repair and rehabilitation restore damaged or deteriorated concrete to safe, serviceable condition — addressing cracks, spalling, delamination, honeycombing, and reinforcement corrosion through engineered repair systems, structural strengthening, and protective treatments that extend service life.

Concrete needs repair when visible distress appears — cracking, spalling, exposed rebar, moisture ingress, or loss of load-bearing capacity — or when condition assessment reveals chloride attack, carbonation, chemical attack, or structural deterioration that threatens durability or safety.

Concrete repair fixes localized defects such as cracks, spalls, and patch areas. Concrete rehabilitation is broader — restoring overall structural integrity, upgrading load capacity through strengthening, and applying protection systems for long-term concrete durability and service life extension.

OSISCO conducts structural inspection and concrete condition assessment — visual surveys, hammer testing, delamination detection, reinforcement corrosion mapping, chloride and carbonation testing, and structural assessment to define repair scope and repair methodology.

Structural crack repair uses epoxy injection for dormant cracks requiring load transfer, or polyurethane injection for active leaks and moving cracks. Injection grouting with packers restores monolithic behaviour and seals moisture pathways in beams, columns, slabs, and walls.

Spalling repair removes loose material, cleans exposed reinforcement, treats rebar corrosion, and applies non-shrink repair mortar or patch repair compounds with proper substrate preparation and bond strength verification — restoring profile and structural section.

Spalling is typically caused by reinforcement corrosion — chloride attack, carbonation, or moisture ingress causing rebar expansion — as well as freeze-thaw cycles, poor compaction (honeycombing), chemical attack, or structural overstress leading to concrete delamination and cover loss.

Treatment includes removing contaminated concrete, abrasive cleaning of exposed rebar, corrosion inhibitors or rebar replacement where needed, non-shrink repair mortar for section restoration, and protective coating or anti-carbonation coating to prevent recurrence.

Structural concrete repair restores load-bearing capacity and structural integrity — not just surface aesthetics. It combines section restoration, crack injection, bonded overlays, and strengthening systems engineered to meet structural assessment requirements and design codes.

Strengthening is required when load demands increase, structural deterioration reduces capacity, seismic retrofitting is mandated, or condition assessment shows insufficient load-bearing capacity. Methods include FRP strengthening, concrete jacketing, steel jacketing, and section enlargement.

Concrete jacketing encases existing columns or beams with a new concrete or mortar layer — often with additional reinforcement — to increase section size, confine the core, and improve load-bearing capacity. Column jacketing is common for seismic strengthening and capacity upgrades.

FRP concrete strengthening applies fibre-reinforced polymer laminates or wraps — carbon fibre (CFRP), glass, or aramid — bonded to concrete surfaces to increase flexural, shear, or axial capacity. It is lightweight, corrosion-resistant, and ideal for beams, slabs, and columns.

Carbon fiber strengthening (CFRP wrapping) bonds high-strength carbon fibre sheets or plates to concrete using structural epoxy adhesives. The composite acts with the concrete to carry tensile forces, increasing flexural and shear capacity without adding significant dead load.

Cost depends on defect extent, access, repair system (patch vs injection vs FRP), structural strengthening scope, and QA requirements. OSISCO provides quotations after site survey — contact our Egypt or Saudi Arabia teams for project-specific pricing.

Localized patch repair may complete in days; comprehensive structural rehabilitation of buildings or infrastructure can span weeks to months depending on area, curing requirements, strengthening systems, and operational constraints such as partial occupancy or live traffic.
