CONCRETE PROTECTION & WATER PROOFING

FlexJoint’s Injection Division handles specialized contracts involving waterproofing repair by injection, concrete strengthening, curtain injection, soil stabilization, and underwater injection works. Backed by a team of highly skilled technicians and state-of-the-art equipment, we deliver precise and effective solutions for complex structural challenges. With an unmatched track record and a portfolio of unique, high-profile references, FlexJoint is a trusted name in specialized injection applications.

FlexJoint provides advanced soil stabilization solutions using specialized injection materials like cement, ultra-fine cement, rigid PU, and acrylic resins—effectively improving bearing capacity across complex soil conditions in geotechnical and infrastructure projects.

Whether it's leaking cracks in basements and manholes, gushing water through secant piles, or poorly sealed penetrations, FlexJoint has the equipment, skilled personnel, and technical expertise to deliver effective injection-based waterproofing solutions. We specialize in the use of PU resins, acrylic resins, and ultra-fine cements to seal and protect structures under even the most challenging conditions.

FlexJoint offers advanced concrete strengthening solutions through injection techniques using ultra-fine high-strength cement, epoxies, moisture-tolerant epoxies, and rigid PU. These materials are selected based on specific site conditions, such as cavities and cracks in dry, moist, or saturated environments. With proven techniques and specialized expertise, we deliver reliable reinforcement for structurally compromised concrete.

In cases where waterproofing in underground basements is severely damaged and conventional injection methods are no longer effective, FlexJoint offers an advanced solution through curtain injection. This technique allows us to create a new waterproofing membrane behind the structure, even when the existing system—whether PVC, EPDM, HDPE, or bituminous—is adhered or loosely laid. Using acrylic gel injections, we can install a brand-new, fully functional waterproofing system without the need for full membrane replacement.
