Spal-Pro Stabilizer EXP by Metzger McGuire is a high-density, two-component polyurethane foam specifically developed to address rocking, deflecting, and unstable concrete slabs. Designed for industrial and commercial floor repair, this rapid-expanding material is injected beneath the slab to fill voids caused by subgrade settlement, slab curl, or construction deficiencies. Once injected, the foam expands six to eight times its original volume, forming a rigid, closed-cell structure that supports heavy loads and minimizes slab movement.
The hydrophobic properties of Spal-Pro Stabilizer EXP ensure that it resists moisture infiltration, protecting the sub-slab environment from water damage caused by scrubbing, cleaning, or groundwater intrusion. Its rapid cure time allows facilities to return to full service in as little as 45 minutes after application, minimizing operational disruptions. With a medium viscosity for easy flow into narrow voids and strong bond strength to the surrounding substrate, Stabilizer EXP delivers reliable, long-term stabilization even in demanding, high-traffic environments.
Supported by over 35 years of Metzger McGuire’s experience in floor slab protection, Spal-Pro Stabilizer EXP provides a proven solution for mitigating slab deflection, correcting joint instability, and extending the life of concrete floors. Whether addressing early signs of slab movement or repairing extensive subgrade voids, Stabilizer EXP offers contractors and facility managers a fast, durable, and cost-effective method to protect critical flooring infrastructure.
