Guniting (also known as Shotcrete) is a highly efficient and effective technique for large-scale structural repair and restoration. This method involves pneumatically spraying concrete or mortar (cement and sand) onto a surface at a high velocity. This creates a highly dense, compact, and durable layer of repair material, crucial for stabilizing weakened or damaged civil structures.
Key Problems We Solve:
- Structural Weakness: Restoring strength to old or damaged load-bearing walls, foundations, and beams that have lost concrete mass.
- Seepage Barriers: Creating a dense, monolithic, and waterproof shell (like a barrier wall) in basements, water tanks, and tunnels to withstand external pressure.
- Soil Stabilization: Applying a thin, fast-setting layer to excavated slopes or embankments to prevent soil erosion and collapse (slumpage).
- Corrosion Protection: Encasing exposed or corroded reinforcing steel (rebar) in a protective, alkaline concrete layer to prevent further rust and deterioration.
Our Specialized Guniting Techniques:
- Dry-Mix Process: We utilize the dry-mix process where water is added at the nozzle, allowing for better control over water content and ensuring a higher-strength final product.
- Wire Mesh Integration: Incorporating steel wire mesh or fibers into the structure before guniting to provide increased tensile strength and crack resistance.
- Layering for Density: Applying the material in controlled layers to achieve the required thickness and compaction, ensuring minimal rebound and optimal density.
- Quality Control: Continuous monitoring of nozzle distance and material consistency to ensure uniform quality and superior bonding to the existing substrate.
Result: We deliver a high-density, low-permeability repair layer that restores the structural capacity of the member, provides superior waterproofing capabilities, and significantly extends the service life of the structure.
