Division 02 — Construction / Concrete Repair
Concrete Repair & Protection
Structural concrete repair is the systematic restoration of deteriorated or damaged concrete to its original load-bearing capacity and durability, using specialist repair mortars, bonding agents, corrosion inhibitors, and protective coatings — applied in a defined sequence from substrate preparation through to anti-carbonation finishing.
CFC Egypt manufactures a complete structural repair system at our Sadat City plant, covering every stage of the repair process: acid etching and cleaning for surface preparation; polymer-modified and epoxy bonding agents that develop reliable adhesion to old concrete; polymer-modified cementitious repair mortars (EGYREP 1 and EGYREP 2) and a fibre-reinforced grade for added crack resistance (EGYREP 2F, usable up to around 25 mm); polymer-modified cementitious putty and coating (EGYCEM C) for skimming, filling, and protecting surfaces; and epoxy putty and cementitious paste for filling and resurfacing work. Each product in the system is formulated to be compatible with the others and with the substrate concrete, so that differential shrinkage and thermal movement do not cause the repaired zone to re-crack or delaminate.

Kapsam
Concrete repair chemistry spans five product families, each addressing a specific stage of the repair process. A complete and durable repair always follows the full sequence — skipping stages is the leading cause of repair failure.
01
Surface Preparation
All deteriorated concrete must be removed to a sound substrate before repair materials are applied. Mechanical preparation (scabbling, grinding, or shot-blasting) is the primary method; EGYACID-ETCH provides chemical surface treatment where mechanical methods cannot reach or where a concrete surface must be opened and decontaminated before bonding. The target surface is a clean, sound, rough profile with a minimum tensile strength of 1.5 N/mm² and free of laitance, carbonation, dust, and contamination.
02
Bonding Agents
Bonding agents develop the adhesive interface between the prepared substrate and the repair mortar. Polymer-modified cementitious slurries (EGYBOND L, EGYBOND Latex, EGYBOND SBR) suit most cementitious repair applications and are applied wet-into-wet before the repair mortar is placed. Epoxy bonding agents (EGYBOND EP) are used for structural repairs requiring high bond strength or where the substrate is contaminated with chloride or carbonation that would interfere with cementitious bonding.
03
Repair Mortars & Surface Putty
CFC Egypt's EGYREP series covers polymer-modified, high-strength cementitious repair mortars: EGYREP 1 and EGYREP 2 for structural repair of deteriorated concrete and patching of masonry and render, and the fibre-reinforced EGYREP 2F for repairs up to around 25 mm thickness with added crack resistance. EGYCEM C is a two-component polymer-modified cementitious putty and coating used to skim, fill, and protect concrete surfaces, while EGYPASTE C is an extra-fine polymer-modified cement putty for repairing and resurfacing concrete and masonry.
04
Crack Filling & Honeycombing Treatment
Cracks, honeycombing, and surface voids that do not require structural repair can be filled with EGYPOX PUTTY (a three-component non-shrink epoxy putty for puttying and bonding) or EGYPASTE C (an extra-fine cementitious paste for surface voids and resurfacing). EGYSEAL INJECTION is a one-component cementitious injection slurry that is injected into cracks and voids to stop seepage through concrete and masonry by filling and sealing them from within.
05
Rebar Treatment & Corrosion Protection
Exposed reinforcement in repair areas must be cleaned to bare metal and treated with a corrosion-inhibiting primer before the repair mortar is applied. Without this step, active corrosion continues beneath the repair, causing rapid re-spalling. Epoxy-modified cement coatings and zinc-rich primers bond to the steel surface and provide a passive chemical barrier against further chloride and moisture-driven corrosion, extending the effective life of the repair.

Nerede Kullanılır?
Concrete repair is required in any structure where deterioration has reduced structural capacity, increased the risk of continued degradation, or created a safety hazard. The older the concrete stock and the more aggressive the environment, the greater the demand for repair.
Bridges & Highway Structures
Bridges, flyovers, and highway structures are among the highest-priority concrete repair applications because structural failure has immediate safety consequences. Soffit spalling from carbonation and chloride-driven rebar corrosion, deck delamination, and parapet deterioration are common repair scenarios. CFC Egypt's repair system — preparation, bonding agent, EGYREP mortar, and protective coating — is designed to deliver the bond strength and durability that structural repair of highway assets requires.
Buildings & Residential Structures
Balcony soffits, column bases, and beam ends in residential and commercial buildings are the most common locations for concrete spalling driven by carbonation. Repair work in occupied buildings demands low-dust application methods, rapid strength gain to minimise access restrictions, and a durable protective finish that prevents recurrence within a reasonable maintenance interval. CFC Egypt's trowel-applied and spray-grade repair mortars are formulated for these conditions.
Industrial & Wastewater Structures
Concrete in chemical plants, sewage treatment works, and industrial sumps is subject to aggressive chemical attack — acids, sulfates, hydrogen sulfide, and high-pH effluents — that accelerates deterioration well beyond what would occur in a normal atmospheric environment. Repair of these structures requires mortars and coatings specifically formulated for chemical resistance, and the repair process must address both the physical damage and the ongoing chemical exposure through an appropriate protective coating system.
Marine & Coastal Structures
Jetties, sea walls, quay aprons, and coastal buildings in Egypt's Mediterranean and Red Sea environments experience aggressive chloride exposure that drives rapid rebar corrosion and concrete spalling. Marine repair work must address both the structural damage and the chloride contamination of the surrounding concrete — requiring specialist mortars with low permeability, thorough rebar treatment, and protective coatings that resist chloride diffusion to prevent the corrosion front advancing after repair.
Infrastructure Rehabilitation
Large-scale infrastructure repair programmes — canal lining rehabilitation, dam face repair, culvert restoration — require repair materials that can be applied rapidly over large areas, achieve consistent quality with contractor labour, and perform reliably over long maintenance intervals without access for re-treatment. CFC Egypt's system products provide the mix consistency, pot-life management, and contractor support that large infrastructure repair projects need.
