"AJ and his crew did a great job for us. They were reliable, efficient, and competitively priced. Impeccable clean-up during and after the job. AJ gave us some good advice for improved drainage around the outside of our house as well. It is obvious that he cares about his customers. It is such a relief to have a dry basement!"

"Hired them for 3 projects I have installed this basement waterproofing solution in 2 homes. System speaks for itself. Nothing better on the market. Work was first rate. Expectations were presented prior to the project. Details on what would happen and how the project would go. Would not hesitate to use again ERV installed New basement egress. This project did not go as planned, but not at the fault of basement systems. Was originally supposed to get a BILCO door but due to unforseen issues, that was not able to happen. They ended up installing a new staircase from my basement to ground level. Work was first rate and ended up better than a bilco door. Company re landscaped and everything is as it was. All work performed was top notch and no issues on anything they have done"

"I bought a house in 2021 that had significant water damage leaking through the walls onto the concrete floor in the basement. After researching multiple companies around the area, I reached out to Basement Gurus. Ashley, Boni, Josh, and owner of the company Dan Kelly, all went above and beyond to make sure that there would be no more water damage. They installed a French drain, vapor barriers, and more. The owner Dan Kelly personally came out to make sure that the work got done correctly. This company is the best around, you won't be disappointed."

"Make sure the person giving the estimate explains exactly what it looks like. They did not bring their own water to mix the cement. We had to remove the water tank so that they could work and ended up hauling water from the neighbors house."

House Leveling questions, answered by experts

Polyjacking and mudjacking can both be effective solutions for sinking concrete, but they have key differences. Polyjacking, which uses expanding polyurethane foam, is often considered a better option because the foam is significantly lighter than the cementitious material used for mudjacking. This reduced weight puts less pressure on the underlying soil and lowers the risk of future sinking. Polyjacking is suitable for any sinking concrete slab, while mudjacking is typically only recommended for non-structural concrete, such as sidewalks, patios, pool decks, and driveways. The primary drawback of polyjacking is its cost, which can be up to four times higher than mudjacking—as much as $25 per square foot compared to a maximum of about $6 per square foot for mudjacking.

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

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.

Common issues with concrete that may require professional repair or resurfacing include cracks, spalling, uneven surfaces, and weather damage.

Yes, expanding foam (also known as polyurethane foam) can lift concrete. This approach, called polyjacking, involves injecting the foam rather than concrete slurry to fill voids and raise the concrete slab back into place. It’s often faster and requires smaller drill holes than traditional mudjacking, though it may come at a higher cost. Some contractors also prefer polyjacking over mudjacking for more damaged and delicate slabs.
