Get matched with top concrete mudjacking pros in Charlestown, NH

Boring (also known as directional boring) is one alternative to trenching when installing underground utilities. The main difference between directional boring versus trenching is that boring doesn’t require digging or disturbing the surface. Instead, it involves creating holes or tunnels in the ground and then running utility lines through the openings. Boring is less invasive than trenching, but it’s also more expensive.

It’s possible to rent the equipment necessary to do your own mudjacking, but we don’t recommend it. Mudjacking involves pumping a precise amount of cementitious slurry under your slab to lift it back into place and keep it there. It’s easy to pump too much or not enough, in which case you may need to call in a professional to help anyway. We strongly recommend against mudjacking any load-bearing slab, as you could easily cause irreversible structural damage to your property if you make a mistake. This is one job where paying for a professional is worthwhile.

Mudjacking can take 24 to 72 hours to cure enough to resume normal use. Because the slurry mixture contains cement, it needs to fully harden to ensure that added weight won’t shift the concrete slab before it has completely set. Your concrete contractor will be able to tell you when you’re free to use your concrete surfaces again after mudjacking.

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.
