"Donald and Guiles came to complete a job at my home in Granby, MA in September 2026. They were extremely professional from start to finish. They arrived on time and took the time to thoroughly explain everything before beginning the project. Throughout the process, they kept me informed and made sure I understood what was happening every step of the way. They worked slowly, carefully, and thoughtfully to ensure the project was completed without causing any damage to my concrete slab. They also pitched my slab perfectly, which was very important to me. I truly appreciate the care, attention to detail, and professionalism they put into the entire job. I would highly recommend them!"
"Thrasher did an excellent job repairing our driveway. They leveled out the entire driveway with amazing precision, and they fixed all the gaps with an attractive sealant that blends beautifully with the concrete. All of the team members I interacted with were professional and polite. I am very pleased with the results and only wish I’d called them sooner."
"Our sump pump broke and the line froze, so they replaced it with a triple pump system with freeze guards that keep the water from freezing outside and blocking the line. The new sump pump system is so much nicer, bigger, and SO quiet. The electrician, Greg, went out of his way to find a circuit with one item on it and tied into that so we did not need any drywall ripped up...very nice. We have also been battling a basement leak for almost ten years. Jason came and identified the problem and the required fix, then went above and beyond to make sure that all the prep work was done properly and that we were satisfied with what was about to happen, he even came and helped the guys for a while! Mel and his team came, dug up the concrete, and laid a drainage system across one wall of the basement, and took it into the sump pump. At first, I was scared to death listening to all the jackhammering, but from the minute they walked in, the guys were so conscientious about doing everything right and without major upset to our house, it put me right at ease. They were very fast, and the finished product looks amazing, so professional and clean. The entire experience was unbelievable, they all were so helpful, pleasant, knowledgeable, professional. I would recommend Thrasher, hands down, to anyone with any type of basement issue!
Concrete Mudjacking questions, answered by experts
Mudjacking can be an expensive foundation repair process, but in many cases, it’s well worth the investment. This is especially true if you’re lifting a portion of sunken foundation slab back into place. In that case, mudjacking can help avoid major structural damage and even home collapse by restoring the integrity of your structure with minimally invasive procedures. Mudjacking a concrete patio, walkway, or sidewalk can be worthwhile because it removes tripping hazards and makes your outdoor area more aesthetically appealing.
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.
It’s best not to perform mudjacking in the winter unless the ground temperature remains above freezing. Freezing temperatures can cause the slurry to harden too quickly, compromising its strength and longevity. Concrete is also more susceptible to cracking and splitting in cold temperatures, so there’s a higher risk of damaging the slab during the drilling and lifting process in winter.
Charges correlate with surface size, settlement depth, and access, often yielding significant savings over concrete replacement.
A slurry of cement, sand, and water is injected beneath the concrete to lift and stabilize it.
