"Aaron Lenker add Corbin Gillichbauer of Groundworks leveled concrete walks around my corner lot in Montoursville Pa. They arrived around noon time and were finished about 5 1/2 hours later. They did their work very professionally. They did an excellent job. I would rate their work 5 of 5 stars."

"We had known about this problem for some time and had also had a structural engineer evaluate our situation.  We may be putting our house up for sale soon and decided it was finally time to get the wall fixed.  Armed with my own research and the engineers evaluation, we searched for a contractor to perform the work we knew we needed to have done.  Upon contacting Foundation Experts, Larry got back to me very quickly and we set up an appointment for him to inspect the wall.  He was VERY thorough in explaining what needed to be done to stabilize the wall to prevent any further movement/damage.  He said we should have the wall "pinned".  He quoted us $4000 to do the whole job (10 pins along a roughly 25ft. long wall).  They also designed the system so that the re-bar would pass through the top course of block and attach to the house sill plate above the wall to help lock it in place.  
The price was on par with most other estimates (slightly cheaper actually), but we decided to go with Foundation Experts mostly because they were very thorough with their evaluation, were honest (I was armed with a lot of info about our situation and felt very confident that what he proposed to do was exactly what needed to be done) and they did not pressure us at all.  I also really liked the fact that they routinely work with engineers and felt that they had a better grasp on executing the work over other contractors we contacted.  They also will work with the township if permits are needed.
We scheduled for the work to start the following week.  Their team took about 2 days to do the work.  They were very professional and did not make a mess at all.  They put plastic up to prevent concrete dust from getting everywhere in the basement and cleaned up thoroughly.  Larry was present during the bulk of the work and made sure that everything went smoothly.  They even worked with us on the payment method.  He made it very clear if we have any issues/concerns or questions to call them anytime.  He also stressed that if we sell the house and potential buyers have any questions/concerns to contact him and they will work with us as best they can.  
The wall is now fixed and my wife and I feel better knowing that our wall won't come crashing down during then next heavy rain!  We also feel better knowing that we won't have to worry about foundation issues coming up if/when we sell our house.  All in all, it was a great experience!

Concrete Leveling questions, answered by experts

A slurry of cement, sand, and water is injected beneath the concrete to lift and stabilize it.

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. 

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.

On average, a mudjacking repair lasts between five and 10 years, though it can sometimes last for well beyond a decade under ideal conditions. Its longevity depends heavily on several factors, including the condition of the underlying soil, environmental conditions like freeze/thaw cycles and erosion, and whether the root cause of the sinking, such as drainage issues, is resolved. Because it doesn't always fix the underlying problem of loose soil, mudjacking is often considered a temporary solution. Proper maintenance and evaluation can help extend its lifespan.

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.
