House Leveling FAQs, answered by experts

Trenching and boring are two distinct methods for installing underground utilities. Trenching involves digging a channel using equipment like an excavator, trencher, backhoe, or shovel. While it is a simpler process, it causes significant disruption to the surface, landscaping, and surrounding ecosystems.

Boring, also known as directional boring, is a less invasive alternative that uses a drill to create a tunnel for utility lines without disturbing the surface. This method is more precise and is ideal for installations that need to go underneath buildings, roads, or bodies of water. Although boring is less disruptive, it is generally more expensive than trenching.

The method involves lifting settled concrete using pressurized cement slurry via drilled holes. This solves uneven surfaces and prevents further settling.

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 foundation repair pro to determine the best way to lift your sinking foundation. 

The timeframe is generally a few hours, allowing for immediate use post-hydration, ensuring minimal disruption to surrounding activities.

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.
