"I have had two issues since they installed the new sump pump and irrigation. Issue number one was water still getting passed the new concrete. The other issue is that the new concrete was not level at all which has caused issues with the new flooring I installed. However, their customer service is top notch and will work hard to take care of you."

"While such work is not cheap, Terra Firma stayed with us throughout, including during some delays based on obtaining permits here in Oregon, so that wasn't their fault. The work was outstanding, with a three-person crew putting in three very busy days in cold and wet weather to drive 17 reinforcing titanium piers around roughly half the perimeter of the foundation, with most of them extending clear down to bedrock. They also managed to raise both sliding corners of the house, from slopes of about 1.5" (4 cm) on either corner, back to their original level, which amazed us (we were hoping to have just stabilization, with the possibility of raising the foundation just partway). The house sits on a very steep slope leading down to a creek, and years of slow but noticeable "sliding down the hill" are now not only corrected, but the whole foundation is now as level as when it was constructed 25 years ago. Perhaps needless to say, we're thrilled with the results. Contact Mike O'Brien at their Roseburg office near Eugene to get started: the company will do laser-specific measurements of your building to see if its base is off at all. The staff also does NOT engage in high-pressure sales tactics, so rest easy if you have him or someone else come over for an evaluation."

"Decided on a price that included prep, materials, and the pouring of the concrete. the day before the pour the guy came by to prep the areas and he showed up with what looked to be 2 of his sons that were under 14 years old. But what ****** me off was him telling me that it would cost extra to get rid of extra debris from him leveling the areas, an extra ($200). I told him no way and to figure somewhere else to dump it. He ended up dumping it behind my property line. The next day, I thought fresh start let see how they do, Overall the work was decent but in some spots a little sloppy. But what took the cake was, when the concrete truck came he needed cash to pay the driver. So I paid him the whole bill in cash. I had the exact amount to pay him for the whole job, being that I was just at the back and got the exact amount. He took the money didn't count it, then after the work was completed and all was said and done he knocks on my door and tells me that I shorted him 200$. I told him no way that was possible. I believe he either paid the concrete guy to much or was unhappy the day before I wasn't willing to pay for a dump run that he should have quoted me. I handed him some spare cash I had and he left. I Learned when paying cash. Have the guy count the money in front of you to make sure you don't get screwed."

Concrete Leveling questions, answered by experts

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. 

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.

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.

It restores concrete, prevents replacement cost disruptions, reduces trip hazards, and provides stability at a lower cost.

Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The total drying time can vary depending on the size of the project. Because the slurry mixture contains cement, it needs to harden fully to prevent the concrete slab from shifting under added weight. You should avoid walking on the concrete or placing heavy items like furniture or vehicles on the surface until it has fully set. Your concrete contractor can provide a precise timeline. As a point of comparison, if you opt for polyjacking, the polyurethane foam can dry in minutes, but it's recommended to wait about an hour before use.
