Mudjacking vs PolyLevel: What's the Best Concrete Repair Method?

Why Does Concrete Sink & Crack?

Though concrete is strong and durable, it's only as stable as the soil that lies beneath it. Over time, soil can compact or even wash away due to multiple factors, including rain, drought, or the initial compaction during construction. When the soil is dry and erodes, it starts to crack and form holes, called voids. The soil loses its density and can't support the weight of the concrete slab above it, causing the slab to sink into the voids. 

What is Mudjacking?

Mudjacking, often called slabjacking or pressure grouting, is a method that has been used for several decades. The mudjacking process involves injecting a mud-like mixture beneath the slab. The installer drills holes and injects the mud-like mixture. The "slurry" is a special mixture of water, soil, and cement, hence the name "mudjacking." This mud-like slurry, when pumped under pressure, fills voids and gaps beneath the slab. 

Pros of Mudjacking:

• Most affordable
• Tried and true
• Eco-friendly

Cons of Mudjacking:

• Messy and disruptive
• Large injection holes
• Not a permanent fix

What is PolyLeveling?

PolyLevel is a concrete lifting technique that involves injecting high-density, structural grade polyurethane foam to lift, level, and stabilize your concrete slabs. If mudjacking is the tried-and-true concrete repair method, then think of PolyLevel like its cooler, younger sibling. It's a newer method that uses the same concept as mudjacking, but improves upon it using better materials. The process involves injecting the polyurethane foam beneath the concrete slabs through small ports, roughly the size of a penny. The foam itself starts as a liquid, but quickly expands and hardens to support the concrete. In it's liquid state, it flows like water, filling in every crack and crevice in the soil to provide necessary support. Once it hardens, it lifts the concrete above it and compresses the soil around it, all at the same time. 

Pros of PolyLevel:

• Permanent solution
• Small injection holes
• Non-invasive
• Lightweight, but durable

Cons of PolyLevel:

• More expensive
• Requires professionals

So Which Method is the Right Choice for You?

While mudjacking is a cost-effective and traditional solution, PolyLevel provides long-term results and a better look. But at the end of the day, it ultimately depends on your specific project, budget, and long-term expectations. To make the best choice, weigh the pros and cons carefully and consider your unique needs. Do you want a quick, short-term fix? Or a quick, long-term fix?
