Q: What materials are used in mudjacking?

• <div><p>A slurry of cement, sand, and water is injected beneath the concrete to lift and stabilize it.</p></div>

Q: How long does it take for polyjacking to cure?

• <div><p>The polyurethane used for polyjacking will expand and cure in 15 to 30 minutes. After that point, your slab will be safe to walk on and even drive on in the case of a sidewalk or concrete driveway. Double-check with your concrete lifting specialist to confirm a curing timeline, as products can differ. </p></div>

Q: Is there an alternative to underpinning?

• <div><p>There is no real alternative to underpinning, although mudjacking and polyjacking are other repair methods that can add support from underneath your foundation. Rather than placing supportive piers under your structure, these involve pumping a material under your slab to lift a sunken section back into its original position. Polyjacking, in particular, is sometimes a suitable solution for stabilization issues under slab foundations, but underpinning is often accepted as the best and most permanent solution.</p></div>

Q: What is a good slump height?

• <div><p>A good slump height really depends on the project, but there is a use for nearly all slump levels. For example, low slumps are best in projects that require structure, such as curbs and roads. High slumps often require additional reinforcement, but they flow more freely into hard-to-reach spaces. </p></div>

Q: Can you lift a sinking foundation?

• <div><p>A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a <a href="https://www.angi.com/nearme/foundation-repair/">foundation repair pro</a> to determine the best way to lift your sinking foundation. </p></div>

Wanted a concrete pad but Derek noted major drainage problems. He removed grass and dirt and graded and installed new sod plus the pad. I am very pleased with the work as is the neighborhood!

It was a pleasure meeting and working with Ben and his crew. We had a fairly small job, but they gave it their full attention. Quality work and great outcome. We will certainly think of Ben for any future concrete work. We would highly recommend Ben and crew for any job, big or small.
