Overview / Introduction
Headline: Giving Your Concrete a Second Life
Concrete is the foundation of modern infrastructure—strong, durable, and reliable. However, no material lasts forever without intervention. Over time, concrete structures in Saudi Arabia face unique challenges: harsh coastal environments, temperature extremes, chemical exposure, and simply the weight of years of service.
At Arabian Company for Protection and Strengthening, we specialize in diagnosing and reversing concrete deterioration. Our Concrete Repair and Restoration services are designed to address everything from superficial surface damage to deep structural decay. We don’t just patch problems—we restore the original design strength and protect the structure against future damage, extending its service life by decades.
Whether it’s a residential foundation, a commercial parking garage, or an industrial facility, we bring deteriorated concrete back to life.
The Signs of Concrete Distress
Headline: Is Your Concrete Telling You Something?
Concrete rarely fails without warning. Recognizing the early signs of distress can save millions in replacement costs and prevent safety hazards. You may need our Concrete Repair services if you observe:
- Cracks & Fractures: Visible surface or through-section cracks indicating movement or stress.
- Spalling & Delamination: Flaking, chipping, or large pieces breaking off the surface.
- Efflorescence: White, powdery deposits on the surface indicating moisture penetration.
- Rust Staining: Discoloration revealing that reinforcing steel (rebar) is corroding inside.
- Surface Scaling: Wearing away of the surface layer due to weather or chemical exposure.
- Settlement or Sagging: Visible signs that the structural integrity has been compromised.
If you notice any of these signs, immediate assessment is critical.
Our Concrete Repair Process
Headline: Our Systematic Approach to Concrete Restoration
Effective concrete repair is not just about mixing mortar and patching a hole. It requires a systematic engineering approach to ensure the repair lasts and addresses the root cause of the damage.
Step 1: Diagnosis & Investigation
We begin with a thorough investigation to determine the extent and cause of deterioration.
- Non-Destructive Testing (NDT): We use advanced tools such as the rebound hammer (to test surface hardness), ultrasonic pulse velocity (to detect internal voids), and half-cell potentiometers (to map corrosion activity in the rebar).
- Delamination Survey: We “sound” the concrete by chain dragging or hammer tapping to identify hollow areas where concrete has separated from the steel.
- Carbonation & Chloride Testing: We analyze samples to determine if chemical attacks have penetrated the concrete and reached the reinforcing steel.
Step 2: Surface Preparation
The success of any repair depends on the preparation of the substrate. We remove all unsound concrete and contaminants.
- Hydro-Demolition / Water Jetting: Using high-pressure water to selectively remove damaged concrete without micro-fracturing the sound concrete (unlike jackhammers).
- Mechanical Preparation: Chipping hammers and scarifiers for targeted removal.
- Substrate Cleaning: Ensuring the surface is free of dust, oil, and loose particles to guarantee optimal bond strength.
Step 3: Reinforcement Treatment
If the steel reinforcement is exposed and corroded, it must be treated before new concrete is placed.
- Steel Cleaning: Removing rust and scale to bare metal using sandblasting or wire brushing.
- Corrosion Inhibitor Application: Applying a protective coating to the rebar to prevent future oxidation.
- Sacrificial Anode Installation: In severe cases, we install zinc-based anodes to actively protect the rebar from corrosion.
Step 4: Application of Repair Materials
We utilize high-performance, cementitious repair mortars and concretes designed for specific applications.
- Form & Pour: For deep repairs, we use formwork and pour free-flowing, non-shrink grout.
- Trowel Application: Hand-applied polymer-modified mortars for vertical and overhead surfaces.
- Spray Application (Shotcrete/Gunite): For large areas, we apply repair material pneumatically for high strength and density.
Step 5: Curing & Protection
Proper curing is essential for the repair material to achieve its full strength and durability.
- Controlled Curing: We use membrane-forming curing compounds or wet burlap to control the rate of moisture loss.
- Protective Coatings: Application of sealers or anti-carbonation coatings to protect the repaired area from future ingress of chlorides and moisture.
Key Concrete Repair Services We Offer
1. Spalling & Delamination Repair
When concrete breaks away from the rebar, it creates a safety hazard and accelerates corrosion. We remove all loose material, clean the steel, and rebuild the section with high-strength repair mortar, restoring the original profile and protecting the embedded steel.
2. Structural Crack Repair (Epoxy & Polyurethane Injection)
Not all cracks are the same. We use two primary methods:
- Epoxy Injection: For structural cracks. We inject low-viscosity epoxy under pressure to bond the cracked concrete back into a monolithic unit, restoring its original strength.
- Polyurethane Injection: For active or leaking cracks. The resin expands upon contact with water, forming a flexible seal that stops water ingress permanently.
3. Corrosion Damage Repair
Corrosion of reinforcing steel is the number one cause of concrete deterioration. We remove chloride-contaminated concrete, clean the rebar, apply corrosion inhibitors, and rebuild the section. For long-term protection, we can integrate cathodic protection systems into the repair.
4. Surface Scaling & Abrasion Repair
Floors, pavements, and industrial slabs often suffer from surface wear due to traffic or chemical exposure. We apply high-strength, abrasion-resistant toppings and overlays that bond to the existing substrate, providing a new, durable wearing surface.
5. Honeycombing & Voids Filling
Construction defects or poor vibration during pouring can leave voids (honeycombs) within the concrete. We inject specialized grouts to fill these voids, ensuring the concrete becomes solid and uniform throughout.
6. Concrete Protection & Coating
After the repair is complete, we offer protective treatments to extend the life of the structure:
- Anti-Carbonation Coatings: To neutralize the effects of atmospheric CO2.
- Water-Repellent Sealers: To prevent moisture and chloride ingress.
- Industrial Floor Hardeners: To increase surface density and durability.
