At EG CORE, we specialize in acrylic gel injections to effectively seal fine cracks and joints in concrete and masonry structures. Our low-viscosity acrylic resins penetrate deeply, forming a flexible, gel-like seal that accommodates structural movements and prevents water pressure. This method is ideal for applications such as tunnel linings and retaining walls, ensuring long-lasting protection against moisture.

Our polyurethane injection services are designed to halt active water leaks in concrete structures. Utilizing hydrophobic or hydrophilic polyurethane resins, we inject these materials into cracks and joints, where they expand to form a dense, closed-cell foam. This process effectively fills voids, creating a resilient, watertight seal that adapts to slight structural movements, enhancing the integrity of below-grade structures, tunnels, and water-retaining facilities.

We offer cementitious injection solutions to restore the structural integrity of concrete structures. By injecting fine cement-based grouts into cracks, voids, and honeycombs, we reinforce the concrete matrix, improving its load-bearing capacity. This technique is particularly effective for stabilizing deteriorated masonry, underpinning foundations, and sealing static cracks in large-scale infrastructure such as dams and bridges.

Our epoxy injection services focus on bonding and sealing non-moving cracks in concrete structures. We utilize high-strength epoxy resins that, once cured, restore the original strength and integrity of the concrete. This method is ideal for repairing dormant cracks in beams, columns, and slabs, preventing the ingress of water and corrosive agents, and thereby extending the service life of the structure.

For complex geotechnical challenges, we employ combi-grouting systems that integrate multiple grouting materials and techniques. By combining materials such as polyurethane foams for immediate water stoppage and acrylic gels for flexible sealing, we offer comprehensive solutions for ground stabilization, void filling, and waterproofing. This approach is particularly beneficial in tunneling and mining operations, where varying ground conditions require adaptable and multi-faceted injection strategies to ensure structural stability and water tightness.
