Aggregate Concrete Raising
A stronger, cleaner, and longer-lasting solution for lifting concrete and filling voids. Our proprietary aggregate blend provides exceptional strength, stability, and performance — far exceeding traditional mudjacking and avoiding the long-term issues associated with foam injection.
Why Choose Aggregate Raising?
Raising concrete is only as reliable as the material placed beneath it. While foam and traditional mudjacking often break down, compress, or deteriorate over time, aggregate creates a dense, stable, load-bearing foundation. Our custom blend is engineered for long-term structural integrity — not just pumpability or temporary lift. With superior compaction strength, environmentally safe ingredients, and proven performance, aggregate is simply the best material available for concrete raising.
What Makes Our Aggregate Raising Blend Different
(and Better)
Our proprietary material is specifically engineered for strength, stability, and natural lock-up. Each component plays a role:
Agricultural Lime (1/8” minus): Fine, angular material that compacts tightly.
Quartz (3/16” minus): Incredibly strong and durable, adding long-term load-bearing support.
Portland Cement: Binds the blend into a solid, unified base.
Topsoil: Helps the material settle naturally and bond with surrounding soils.
Strength You Can Measure
Our unconfined test rating: 160 PSI, which equals 23,040 pounds of support per square foot.
When placed under confinement (as it is beneath concrete), the material reaches 400–600 PSI — making it one of the strongest and most reliable lifting materials in the industry.
This is true structural support — not just a material that fills space.
Aggregate vs. Foam vs. Mudjacking
Not all lifting materials are equal. Here’s how each option truly compares based on measurable performance and real-world longevity:
Aggregate (Our Blend)
Unconfined Strength: 160 PSI
Confined Strength: 400–600 PSI
Material: Lime, quartz, Portland cement, topsoil
Longevity: Excellent — bonds naturally, does not deteriorate
Best For: Residential slabs, commercial concrete, void filling, stabilization, heavy loads
Key Benefit: Strongest structural support with natural lock-up
Why it wins:
Aggregate provides the highest strength and most natural long-term stability. It compacts, locks, and forms a unified base that does not break down over time.
In testing, our material reaching 10% compression would take so much force that we’d break the hydraulic test machine long before our material ever deformed as much as foam. Testing machines go upwards of 10,000 PSI. Our material is significantly stronger.
Foam (High-Density Commercial Foam)
Strength Rating: 150 PSI (confined) — and only for rare, expensive foam types
Material: Synthetic expanding foam
Longevity: Can degrade, shrink, or become brittle with age
Drawbacks:
Not designed for soil stabilization
Can over-expand and lift unevenly
Expensive
Limited PSI ratings unless premium products are used
Where it falls short:
Foam’s strength ratings are often confined only, meaning lab-tested inside a mold — not real-world performance. Even high-density foams cannot match aggregate’s long-term stability.
Foam relies on a compaction test that permits up to 10% deformation, and without that allowance the material would show virtually no measurable strength.
Mudjacking Slurry
Strength Rating: 40–80 PSI
Material: Pulverized limestone, calcium carbonate, or sand
Longevity: Weak — does not lock up, prone to washout or breakdown
Drawbacks:
Designed for pumpability, not strength
Heavy material can cause additional settling
Easily erodes or becomes loose
Why it fails long-term:
Mudjacking often washes out over time because the slurry is mostly water and fine soil, so rain, groundwater, and natural erosion slowly dissolve and carry it away, leaving new voids under the concrete.
Why Material Strength Matters for Concrete Raising
Concrete slabs rely on a stable, locked-in base. When weaker materials are used, the slab may lift temporarily — but it eventually shifts, sinks, or cracks again. High PSI stability ensures:
Slabs stay level long-term
No recurring settlement
Better water drainage
Reduced trip hazards
Stronger support for vehicle or equipment weight
Greater resistance to erosion
With aggregate raising, you’re not just lifting the slab — you’re rebuilding the foundation beneath it.
What to Watch For:
If your concrete is sinking, shifting, or showing signs of structural stress, aggregate raising may be the best option. Here’s how to know when the material beneath your slab has failed:
Signs to Look For
Visible slab settlement or height differences
Deepening cracks spreading across the surface
Water pooling in sunken areas
Gaps between concrete and the foundation
Sinking steps or patio sections
Soil erosion around concrete edges
Hollow or empty sounds beneath the slab
Recurring settlement even after old repairs
Concrete shifting toward one direction
Slab “bouncing” or flexing under load

F.A.Q. for Aggregate Concrete Raising
Q: What makes aggregate raising better than foam?
Aggregate provides higher structural PSI strength and natural lock-up. Foam can degrade over time, while aggregate forms a compact, load-bearing base.
Q: How strong is your aggregate blend?
Our material tests at 160 PSI unconfined and approximately 400–600 PSI when confined beneath a slab — significantly stronger than traditional mudjacking.
Q: How does aggregate compare to mudjacking slurry?
Traditional mudjacking slurry typically ranges between 40–80 PSI and is designed for pumpability, not strength. Our aggregate blend is engineered for structural stability.
Q: Is aggregate environmentally safe?
Yes. Our blend uses natural materials including agricultural lime, quartz, Portland cement, and topsoil.
Q: Will aggregate wash out over time?
No. The material compacts and locks into place, reducing erosion and long-term breakdown.
