Fibre-Reinforced Repair Mortars for Industrial Concrete
Industrial concrete structures are exposed to the combined deterioration effects of chemical attack, mechanical impact, thermal cycling, and aggressive cleaning - accelerating deterioration beyond what occurs in standard civil environments. Repair mortar selection for industrial environments must account for the specific chemical exposure, temperature range, and mechanical loads of the facility - standard concrete repair systems formulated for civil applications often lack the chemical resistance and mechanical performance required in industrial settings.

Application Overview
Industrial Concrete Repair Applications
Chemical Plant Concrete Repair
In chemical manufacturing environments, concrete deterioration is typically caused by acid attack (dissolution of the cement matrix), sulphate attack (expansion and cracking from sulphate reaction with cement components), and in some cases, alkali-silica reaction (ASR) from reactive aggregates in the original concrete. Repair mortars for these environments must be formulated with sulphate-resistant binders and aggregate selections that minimise further chemical attack while achieving the mechanical performance requirements of the structure.
Industrial Floor Slab Rehabilitation
Industrial floor slabs deteriorate through delamination (from impact and thermal shock), joint deterioration (spalling from forklift traffic), surface erosion (chemical and abrasive attack), and structural cracking (from overloading or settlement). Repair of floor slabs requires rapid-strength systems to minimise production downtime, and products compatible with the subsequent floor coating application. Gemite's floor repair mortars are formulated to achieve structural strength within 2-6 hours and provide a suitable substrate for coating within 24 hours.
Technical Highlights
Key Performance Characteristics
Sulphate-Resistant Binders
Gemite's industrial repair mortars use sulphate-resistant cement formulations and pozzolanic binders that resist the sulphate-rich environments common in wastewater, chemical processing, and heavy industry applications.
Fibre Reinforcement
Polypropylene and steel fibre-reinforced formulations provide enhanced crack resistance, impact resistance, and ductility - reducing re-cracking in repair areas subject to thermal cycling and mechanical loading.
High Bond Strength ≥ 2 MPa
Pull-off bond strength greater than 2 MPa ensures the repair remains structurally integral under the combined mechanical and chemical loading of the industrial environment.
EN 1504 Compliant
All Gemite industrial repair systems are designed in accordance with EN 1504 principles - diagnosis of the deterioration mechanism, preparation, repair, and protection - ensuring durability of the repair rather than cosmetic treatment.
Frequently Asked Questions
Industrial Structural Repairs - Technical Questions
What is the difference between industrial repair mortars and standard concrete repair?
Standard concrete repair mortars (used in civil applications such as parking decks and building facades) are formulated for typical civil exposure: freeze-thaw, carbonation, and chloride ingress. Industrial repair mortars must additionally resist: acid and chemical attack, abrasion from industrial traffic and processes, elevated temperature exposure, and compatibility with aggressive substrate conditions (oil-contaminated, acid-etched, or sulphate-saturated concrete). Gemite's industrial repair range uses sulphate-resistant binders, chemical-tolerant aggregates, and fibre reinforcement to address these additional demands. Using standard civil repair mortars in industrial environments leads to premature failure - often within 2-5 years of application.
How is the repair area prepared in a contaminated industrial environment?
Substrate preparation is the most critical factor in repair durability. For industrial substrates, this typically involves: (1) removal of all deteriorated concrete to sound substrate (often requiring hydrodemolition or pneumatic breaking rather than grinding); (2) degreasing of oil-contaminated surfaces with alkaline cleaner, rinsed and allowed to dry; (3) mechanical scarification to achieve surface profile CSP 3-5 per ICRI 310.2; (4) application of bonding agent compatible with the substrate condition. For acid-attacked surfaces, neutralisation with alkali wash before repair is required. Our technical team specifies the complete preparation sequence for your substrate condition.
Can industrial concrete be repaired while the facility remains operational?
Repair during operation is feasible in many cases with careful planning. Rapid-strength repair mortars allow return to service within 2-6 hours for light traffic and 24 hours for full industrial loading. For floor slab repairs, the typical approach is to repair sections during a production shutdown (weekend or planned maintenance), with product selection targeted at the minimum possible cure time. Our project planning team designs the repair sequence to minimise operational disruption - including staging repairs in sections to maintain production flow where possible.
