Metzger McGuire Spal-Pro Stabilizer EXP – 1500ml High-Density Polyurethane Foam

Spal-Pro Stabilizer EXP is a rapid-setting, two-component, high-density polyurethane foam system designed to stabilize and support deflecting or rocking concrete slabs. Packaged in 1500ml dual cartridges (750ml:750ml), it expands up to 7 times its volume to fill voids caused by slab curl or sub-base deterioration. Once cured, it becomes a rigid, closed-cell foam with high compressive and tensile strength. Spal-Pro Stabilizer EXP supports material handling vehicle traffic in under 45 minutes and is ideal for use in warehouses, distribution centers, and other industrial facilities. Its medium viscosity ensures optimal flow into tight voids while resisting moisture and vapor intrusion. USDA/FDA acceptable and designed for interior slab correction applications.

Key Features:

• High-density, closed-cell structural foam for slab stabilization
• Expands 6–8 times its volume to fill under-slab voids
• Supports full slab loads within 45 minutes of application
• Medium viscosity for better penetration into narrow gaps
• Moisture resistant and vapor impermeable once cured
• Compressive strength of 115 psi and tensile strength of 165 psi
• Ideal for slab curl and subgrade void correction
• USDA and FDA acceptable for use in regulated environments
• No CFCs or HFCs used in foam structure development

Frequently Asked Questions:

What is the difference between Stabilizer and Stabilizer EXP?
Stabilizer EXP uses an expansive, high-density foam with a 7:1 expansion ratio, ideal for voids where large volume fill and slab support are required quickly.

How soon can traffic return after injection?
The slab can typically return to full service within 45 minutes of injection at ambient temperatures.

Can this be used in cold environments?
Stabilizer EXP is designed for use at temperatures above 38°F. For colder conditions, consult Metzger McGuire about alternative formulations or procedures.
