Innovative Voided Concrete Slab Solutions
Cobiax USA has been a nationally recognized leader in voided slab structural solutions since 2007. Our mission focuses on delivering straightforward presentations, competent execution of supply contracts, and continuous product development. We specialize in reducing structural weight through engineered voids in concrete slabs, offering cost-effective and eco-friendly alternatives to traditional methods. Our solutions have been implemented in diverse projects across the United States, from academic institutions to cultural landmarks. By eliminating unnecessary concrete, we help clients achieve significant savings in materials, time, and environmental impact.Our team provides technical guidance informed by extensive research and real-world project experience. We collaborate closely with architects, engineers, and contractors to simplify formwork, enhance structural efficiency, and meet evolving design demands. Our voided slab systems integrate seamlessly with post-tensioning, delivering reduced deflection and improved adaptability. Committed to sustainability, we utilize 100% recycled plastic void formers and contribute to LEED certification. With a proven track record spanning decades, we remain dedicated to advancing concrete technology while maintaining the highest standards of safety and performance.

Services
Voided Slab Systems
Our voided slab technology creates engineered hollow spaces within concrete structures to reduce weight without compromising strength. This innovative approach enables longer spans, fewer columns, and improved structural efficiency. Clients benefit from reduced material costs, faster construction timelines, and enhanced sustainability through lower carbon footprint.
Structural Weight Reduction
We specialize in reducing structural loads by 30-35% through strategic void placement in concrete slabs. This minimizes foundation requirements, lowers seismic forces, and improves overall building efficiency. Our solutions maintain safety standards while delivering measurable cost savings for large-scale construction projects.
Sustainable Concrete Solutions
Our eco-friendly systems use 100% recycled plastic void formers and reduce cement consumption by 30%. This lowers CO2 emissions and construction waste while contributing to LEED certification. We help clients meet environmental goals without sacrificing structural performance or design flexibility.
Post-Tensioning Integration
We combine voided slabs with post-tensioning technology to achieve optimal structural performance. This integration reduces deflection, enhances load capacity, and enables innovative architectural designs. Our engineers provide technical support for seamless implementation in complex construction projects.
Vibration Mitigation
Our voided slab systems control vibration in buildings housing sensitive equipment. By eliminating traditional waffle slab forms, we provide flat soffits while maintaining vibration resistance. This solution benefits laboratories, medical facilities, and performance venues requiring precise environmental control.
