Division 02 — Construction / Special Epoxy Systems

Special Epoxy Systems

Special epoxy systems are multi-component, chemically cured materials used in construction for chemical-resistant floor mortars and coatings, precision machine base grouting, crack injection, and long-term protection of steel and concrete in aggressive or immersed conditions — applications where the chemical resistance and mechanical properties of cured epoxy exceed what cementitious materials can deliver.

CFC Egypt's special epoxy range — manufactured at our Sadat City plant — spans the full scope of construction epoxy chemistry. The EGYPOX HC grades cover the HC55 novolak protective coating that cures underwater and at low temperature, and the HC57 and HC60 chemical-resistant, non-slip epoxy floor mortars for industrial floors. EGYGROUT EP epoxy grouts (EP, EP40, EP75) cover precision machine base grouting, while EGYGROUT EP10 is a solvent-free epoxy injection resin for cracks. EGYPOX 3D, EPN, and VR supply high-build epoxy coating and mortar systems for chemically demanding floor and tank lining applications. EGYPOX T2 protects steel structures such as bridges, and EGYPOX FLX gives long-term protection of steel and concrete submerged in fresh water, seawater, or wastewater.

01

What It Covers

Special epoxy systems span five distinct application groups, each exploiting different properties of cured epoxy — from the low viscosity required for crack injection to the filled mortar consistency needed for chemical-resistant floors and load-bearing grout applications.

01

Crack Injection

EGYGROUT EP10 is a two-component, solvent-free epoxy injection resin pressure-injected into cracks in concrete and masonry — typically around 0.1 to 1.0 cm wide — to restore continuity across the crack plane. It displaces air and moisture and cures to a rigid mass, helping to re-establish monolithic behaviour. Used for cracks in columns, beams, slabs, and walls where the crack has compromised structural capacity or watertightness.

02

Chemical-Resistant Floor Mortars & Coatings

EGYPOX HC57 and HC60 are three-component, solvent-free epoxy floor mortars that lay down a chemical-resistant, non-slip screed for industrial floors and bunds exposed to aggressive chemicals; HC60 additionally offers high impact and abrasion resistance. EGYPOX HC55 is a two-component novolak epoxy protective coating designed to cure underwater and at very low temperatures down to around -10°C. Used for chemical-resistant flooring and for protective coating in wet, cold, or chemically demanding conditions.

03

Epoxy Precision Grouts

The EGYGROUT EP series covers precision machine base grouting and structural load-bearing applications. EGYGROUT EP is a three-component, high-strength pourable epoxy grout, while EP40 and EP75 are solvent-free epoxy grouts for grouting gap widths of roughly 10–40 mm and 25–75 mm respectively. EGYGROUT EP10 is a related two-component, solvent-free epoxy injection resin for filling cracks roughly 0.1–1.0 cm wide. Used for turbine and pump bases, column base plates, bridge bearings, and crack repair.

04

Epoxy Coatings & Linings

EGYPOX 3D and EGYPOX VR are solvent-free epoxy coating systems for concrete floors, tank linings, and secondary containment areas requiring chemical resistance to acids, alkalis, oils, and fuels. EGYPOX 3D provides a thick, self-levelling floor coating; EGYPOX VR (vinyl ester reinforced) is used for severe chemical exposure in tanks holding aggressive media. These systems are applied over prepared, primed concrete and cure to a smooth, impermeable surface that is cleanable, hygienic, and resistant to the chemical environment of the application.

05

Flexible & Repair Epoxies

EGYPOX FLX is a high-solids modified polyurethane-epoxy coating for long-term protection of steel and concrete submerged in fresh water, seawater, or wastewater. EGYPOX EPN is an epoxy-novolak system for high chemical resistance in process plant environments. EGYPOX T2 is a flexible, two-component coal-tar epoxy coating for the long-term protection of steel structures such as bridges.

02

Where They're Used

Special epoxy systems are specified wherever the performance demands of the application exceed what Portland cement-based materials can achieve. The following represent the most critical applications in the regional construction and infrastructure market.

Structural Concrete Repair

Cracks, voids, and delamination in structural concrete members — columns, beams, bridges, and retaining walls — require repair materials that restore structural integrity, not merely cosmetic appearance. EGYGROUT EP10 epoxy injection resin restores continuity across a cracked section, while EGYPOX HC57 and HC60 chemical-resistant epoxy floor mortars reinstate hard-wearing surfaces. These grades are used in repair and protection programmes on both new and existing reinforced concrete infrastructure.

Precision Machine Base Grouting

Industrial machinery — pumps, compressors, turbines, printing presses, and CNC machine tools — must be precisely aligned and rigidly supported to prevent vibration, maintain tolerances, and avoid bearing and coupling damage. EGYGROUT EP epoxy grout is poured under the machine base plate after alignment and cures to a rigid, non-shrink mass that locks the machine in its correct position. Unlike cementitious grouts, epoxy grouts resist oil, fuel, and coolant penetration that would cause a cementitious grout to weaken and crumble under dynamic loading.

Chemical-Resistant Flooring

Food processing plants, pharmaceutical manufacturing, battery production, chemical storage facilities, and laboratories require floor finishes that resist the specific chemicals present in the process environment while maintaining hygiene, cleanability, and slip resistance. EGYPOX epoxy floor systems provide chemical resistance profiles across a wide range of acids, alkalis, and organic solvents. The correct system — thin-coat sealer, self-levelling coating, broadcast aggregate finish, or heavy-duty mortar — is selected based on the chemical exposure, mechanical loading, and hygiene requirements.

Tank & Secondary Containment Lining

Concrete tanks, bunds, and secondary containment areas storing chemicals, fuels, or wastewater require impermeable linings that resist the stored medium over the design service life. EGYPOX coating systems provide a seamless, chemically resistant lining applied in multiple coats to achieve the required dry film thickness. For aggressive media — high-concentration acids, solvents, or elevated temperature services — EGYPOX EPN epoxy-novolac or EGYPOX VR vinyl-ester reinforced systems provide the necessary chemical resistance beyond standard epoxy chemistry.

Steel & Immersion Protection

Steel structures and concrete exposed to water and aggressive media require coatings that resist corrosion and chemical attack over the long term. EGYPOX T2 is a flexible coal-tar epoxy coating for steel structures such as bridges, while EGYPOX FLX is a high-solids modified polyurethane-epoxy for steel and concrete submerged in fresh water, seawater, or wastewater. EGYPOX EPN and VR novolak systems extend chemical resistance for tanks and process environments holding aggressive media.

Frequently Asked Questions

Technical and commercial questions on special epoxy systems answered plainly. For a specific application, substrate, or chemical resistance requirement, contact our technical team.

Crack injection is the process of pumping a low-viscosity liquid resin under pressure into cracks in concrete or masonry structures to restore structural continuity, prevent water ingress, or stabilise a crack against further widening. For structural cracks — where the crack has reduced the load-bearing capacity or stiffness of the element — a low-viscosity epoxy injection resin (such as EGYGROUT EP10, for cracks roughly 0.1 to 1.0 cm wide) is used; it cures to a rigid mass to help re-establish monolithic structural behaviour. For water-active cracks where sealing is the priority, a cementitious sealing slurry such as EGYSEAL INJECTION fills and seals the crack. The choice depends on whether the crack needs to be structurally reconnected or simply sealed against water.

An epoxy grout (EGYGROUT EP series) is a multi-component system — epoxy resin, hardener, and aggregate filler — that cures to a rigid, high-compressive-strength mass used for precision machine base grouting, column base plate levelling, and structural applications where the grout must carry direct compressive loads. EGYGROUT EP is the three-component pourable grade, while EP40 and EP75 are solvent-free epoxy grouts for grouting gap widths of roughly 10–40 mm and 25–75 mm respectively. EGYGROUT EP10 is a related two-component, solvent-free epoxy injection resin for filling cracks rather than grouting under baseplates. Unlike cementitious grouts, epoxy grouts are non-shrink on cure, chemically resistant to oils and fuels, and develop strength rapidly — making them suitable for pump and compressor bedplates, bridge bearing pads, and high-load applications.

Epoxy floor systems (EGYPOX flooring grades) are rigid when cured, providing very high compressive and abrasion resistance, excellent chemical resistance to acids, alkalis, and solvents, and a wide range of finishes from thin-coat sealer to heavy-duty mortar screed. They are the standard choice for industrial workshops, food processing plants, laboratories, and chemical storage areas. Polyurethane floor systems are more flexible than epoxy, providing better crack bridging, improved impact resistance, and UV stability on exposed surfaces — making them suitable for car parks, external areas, and applications where thermal movement or mechanical impact is significant.

The EGYPOX HC grades are chemical-resistant epoxy systems. EGYPOX HC55 is a two-component novolak (poly-functional phenol novolak glycidyl ether) protective coating designed to cure underwater and at very low temperatures down to around -10°C. EGYPOX HC57 and HC60 are three-component, solvent-free epoxy floor mortars (screeds) with exceptional chemical resistance and a safe non-slip finish for personnel and vehicular traffic; HC60 additionally offers high impact and abrasion resistance. They are used for chemical-resistant industrial flooring and bunds, and for underwater or low-temperature protective coating where standard epoxy chemistry is inadequate.

Epoxy systems form a rigid bond to the substrate and are sensitive to surface contamination and moisture. Concrete substrates must be mechanically prepared — typically by shot blasting or diamond grinding — to achieve a clean, open surface texture. All oil, grease, curing compound, laitance, and weak surface concrete must be removed. The surface must be dry: most epoxy systems require a moisture content below 4%; some moisture-tolerant primers allow application on damp but not wet surfaces. Any cracks, holes, or depressions should be repaired before coating. Adhesion failures in epoxy floor systems are almost always caused by inadequate surface preparation rather than product deficiency — preparation is the most critical phase of any epoxy application.
