Concrete Patch repair
Concrete patch repair is a process used to restore damaged or deteriorated concrete surfaces by applying specialized repair materials to the affected areas. This technique is employed to address various forms of concrete damage, such as cracks, spalling, surface erosion, and minor structural defects. Concrete patch repair aims to restore both the functionality and appearance of the concrete, preventing further deterioration and extending the lifespan of the structure
Concrete Surface Repair
Our Concrete Surface Repair Services are tailored to address the various types of damage and deterioration that concrete surfaces can experience over time. From small cosmetic blemishes to more significant structural issues, we offer a range of solutions that restore the appearance, functionality, and longevity of concrete surfaces.
Spall Repair: Our experts repair spalled or chipped concrete surfaces, restoring the structural integrity and preventing further deterioration.
Crack Repair: Addressing cracks in concrete surfaces using specialized techniques to prevent water penetration and restore a smooth appearance.
Patching and Resurfacing: Applying repair mortars and resurfacing materials to damaged areas, ensuring a uniform and aesthetically pleasing surface.
Joint Repair and Sealing: Repairing or replacing expansion joints, control joints, and construction joints to prevent water infiltration and maintain durability.
Surface Grinding and Polishing: Enhancing the appearance of worn or uneven concrete surfaces through grinding, polishing, and applying protective coatings.
Reinforcement Corrosion Control
Corrosion of reinforcement occurs due to the presence of moisture, oxygen, and chloride ions in the concrete environment. Carbonation, exposure to deicing salts, and marine environments are common contributors to corrosion.
Reinforcement corrosion control involves the implementation of strategies and measures to prevent or mitigate the corrosion of steel reinforcement embedded within concrete elements.
Cathodic protection is an electrochemical technique used to prevent corrosion in metal structures, particularly in environments where corrosion is a significant concern. This method involves introducing a sacrificial or impressed current to shift the electrochemical reactions occurring on the metal surface, effectively protecting it from corrosion.
How Cathodic Protection Works: Cathodic protection creates an electrical circuit where the metal to be protected becomes a cathode and another metal, often referred to as a sacrificial anode or impressed current anode, becomes the anode. By doing so, the protected metal is intentionally made the site of reduction reactions (cathodic reactions), preventing its corrosion.
Types of Cathodic Protection:
Galvanic (Sacrificial) Cathodic Protection:
- This method involves attaching a more reactive metal, such as zinc or aluminum, to the structure to be protected. The sacrificial anode corrodes instead of the protected metal.
- Commonly used in marine environments for structures like ship hulls, offshore platforms, and pipelines.
- Sacrificial anodes work on the principle of galvanic corrosion, where a more reactive metal corrodes sacrificially to protect a less reactive metal. The sacrificial anode is connected to the structure to be protected, forming a galvanic cell. As the anode corrodes, it releases electrons that flow through the electrolyte (usually moisture) to the structure, preventing the corrosion of the structure itself.
Types of Sacrificial Anodes:
Zinc Anodes: Commonly used in marine environments and freshwater applications. They protect steel structures, ship hulls, pipelines, and offshore platforms.
Aluminum Anodes: Used in both saltwater and freshwater environments. They are effective in protecting structures like boat hulls, bridges, and water tanks.
Magnesium Anodes: Used primarily in freshwater applications. They are employed in tanks, pipelines, and buried structures.
Impressed Current Cathodic Protection:
- An external power source is used to apply a direct current to the structure, counteracting the corrosion process.
- Often used in larger structures like bridges, storage tanks, and pipelines.
Crack Injection System
A crack injection system is a specialized technique used for repairing cracks in concrete structures. This method involves injecting specially formulated resins or grouts into the cracks, effectively sealing them and restoring the structural integrity of the concrete. Crack injection concrete repair service is a minimally invasive and cost-effective solution for preventing water infiltration, reinforcing the concrete, and preventing further damage.
Types of Crack Injection Systems:
Epoxy Injection: Epoxy resin is injected into cracks to bond and seal them. Epoxy injection is suitable for structural cracks and can restore the load-bearing capacity of the concrete.
Polyurethane Injection: Polyurethane resin is injected into cracks, expanding upon contact with moisture and creating a flexible seal. This method is effective for stopping water infiltration and non-structural cracks.
