GELCHEMICAL Provides crack repair and structural strengthening for concrete by a team of expert engineers

Repairing cracks in concrete structures

Cracks in concrete can occur due to various reasons, including material shrinkage, external forces, or the natural deterioration of structures over time. If left unaddressed, these cracks may lead to further issues such as water leakage, reduced structural integrity, and escalating damage.

We provide comprehensive concrete crack repair services, covering all structural areas, including floors, walls, ceilings, concrete columns, beams, and more. Our team of experienced professionals utilizes advanced technology and high-quality materials tailored to each type of crack, ensuring durable and effective solutions.

Crack Repair Process

1. Thorough Inspection and Analysis

• Identify the root cause of the cracks to minimize the risk of recurring damage.

2. Selecting the Appropriate Repair Technique

• Use high-quality materials such as specialized crack-sealing cement or high-bond epoxy to effectively seal the cracks.

3. Restoring Structural Integrity

• Prevent water and chemical leakage, reduce the risk of reinforcement corrosion, and extend the lifespan of the structure.

4. Standardized Repair Process

• Utilize modern techniques such as Epoxy Injection for small to medium-sized cracks and PU Injection (polyurethane foam) for cracks with water leakage.

What Types of Repairs is it Suitable For?

• Concrete floor cracks in buildings and factories
• Cracked concrete walls due to pressure or structural settlement
• Ceilings and concrete beams with cracks from deterioration
• Concrete columns with cracks caused by load-bearing or seismic forces
• Waterproof structures such as water tanks, sewage treatment tanks, and swimming pools that require leakage prevention

Concrete Structural Strengthening with Carbon Fiber Reinforced Polymer (CFRP)

When a concrete structure begins to deteriorate or faces limitations in load-bearing capacity due to increased usage, structural strengthening is an effective solution that enhances the strength of the structure without the need for demolition or complicated extensions.

One of the modern and highly efficient strengthening technologies is the use of Carbon Fiber Reinforced Polymer (CFRP). This composite material, reinforced with fibers, offers superior properties compared to traditional strengthening materials, such as steel reinforcement or enlarging the concrete structure.

What Types of Strengthening Work is CFRP Suitable For?

• Structures that require increased load-bearing capacity, such as old buildings needing a change of use or bridges that need to support higher loads.
• Structures damaged by external forces, such as earthquakes, wind, or vibrations from machinery.
• Structures with weight limitations, ideal for tall buildings or structures that cannot handle additional weight from traditional reinforcement methods.
• Structures that need to be upgraded without demolition, reducing time and costs associated with structural improvements.

Key Advantages of Strengthening Structures with CFRP Sheets

• Lightweight with a higher strength-to-weight ratio compared to conventional materials, not adding extra burden to the existing structure.
• Easy and fast installation, reducing work time and minimizing disruption to space usage, with no need to demolish the old structure.
• Corrosion-resistant, durable in various environments, and free from rust issues like traditional steel reinforcement.
• Highly effective in increasing strength; CFRP can withstand higher tensile forces than conventional steel reinforcement, enhancing the structures safety.
• Adaptable to complex shapes; can be installed on curved or intricate surfaces without excessive bending or modifications.

Process of Strengthening Structures with CFRP Sheets

1️. Inspection and Analysis of the Structure

Our engineers will analyze the structure to determine the appropriate techniques and materials for the strengthening.

2. Surface Preparation

Clean and smooth the concrete surface to enhance adhesion efficiency.

3. CFRP Sheet Installation

Install the CFRP sheets using a special epoxy adhesive to ensure strong bonding with the structure.

4. Testing and Quality Inspection

Verify the bond strength and material durability to ensure that it meets the required standards.

You can be confident in the quality of GELCHEMICAL repair work, carried out by a team of expert engineers. We offer a quality guarantee to ensure that your structure is restored to be strong, durable, and safe for the long term.
