WHY DO ConcretE SLABS crack, Sink, & Settle UNDER HOMES, Sidewalks, and PATIOS?

Concrete is strong and versatile. It can be poured, shaped, and made into just about anything–but it’s not indestructible. When you see cracked concrete, broken slabs, or a sunken driveway on your property – there could be several factors at play.
TerraFirma can diagnose and fix your concrete concerns.

tf cheap building Crack

Poorly compacted soil – When your home was built, the movement of soil around the building site results in poor compaction. Even when the replaced soil is compacted well, it’s never as stable as the original soil. Over time, this can cause voids to form and slabs to settle.

tf dry soil Crack

Dry soil – During dry conditions or even just during periods of warm weather and low precipitation, the soil under your concrete will dry out and shrink, creating voids. The concrete above eventually cracks and sinks into these empty spaces.

tf water cracks Crack

Flooding – Wet, soft soil caused by flooding is just too weak to support the concrete above it. In the worst case, the soil erodes and washes away completely, leaving behind large voids that cannot support the weight of the concrete above.

tf rainwater Crack

Rainwater or gutter runoff – Runoff from gutters or downspouts can cause soil erosion around the perimeter of your home. As soil erodes, it can create voids beneath concrete surfaces such as driveways, walkways, or patios, causing them to sink or become uneven.

tf rotting Crack

Rotting tree roots – Decaying tree roots can create voids or channels in the soil. This can exacerbate existing foundation issues and contribute to soil erosion around concrete surfaces, leading to further settlement or instability.

tf clogged Crack

Clogged gutters – Prolonged exposure to water from overflowing or clogged gutters can saturate the soil around your home’s foundation, causing it to expand and exert pressure against the concrete.

Although TerraFirma wasn’t able to assist with my specific concern, Bailey was extremely professional and thorough. I would definitely recommend having them evaluate your next project.
Professional Thoughtful, Communicative. My wife and I are so glad that we choose to get our foundation fixed with Terra Frima. The salesman Boston was willing to come to our house multiple times and explain what the cracks, separating and sagging floors and multiple slope points meant and how it could affect our home. He gave several different quotes and ideas whether it was to protect our foundation in place, attempt to lift it back into place and how to support our sagging floors. He also helped us triage our three main problems which included the cause which was the water under and surrounding our foundation. After addressing this through installing an extensive waterproofing system within our basement we then installed bracketed piers in order to hold our foundation in place and prevent any further settling. My favorite part of the whole process was interacting with Jake and his crew who actually installed everything.  He did a walkthrough with me explaining every aspect of work they were planning on doing. He patiently answered all of my questions even when they were repetitive. He was also very courteous about our home and property and went the extra mile in order to be as minimally invasive into our garden as possible to install the piers and the sump pump drainage system. He also called and communicated with me when I had concerns or when he wanted to communicate solutions to potential problems. He was clearly experienced with this kind of work and even noticed that my garage foundation was settling and recommended a specific product that could fix the issue cost effectively. He and the very kind Project Manager Bree both advocated for me to receive a great price for the additional work and Bree even organized Jake's crew to come back right away and finish the garage work. When all the work was finished Jake's crew cleaned up and reconcreted very nicely and conducted a closing walkthrough again being patient while fielding all of my wife and my numerous questions. Bree then helped me figure out how to finish out the process and at the end of the day my wife and I felt so lucky that we got to do business with Terra Firma and these individuals.
We had our old concrete lifted so that it was leveled all the way around including a couple of the sidewalks. What a difference! Crew was so professional, worked so hard and our concrete looks wonderful!!!
On November 13, 14 and 20th, 2017, it was our pleasure to have Terrafirma work crew at our home in Medford, Oregon. We were appre-hensive after one bad general contractor experience which left us with one end of our home requiring foundation stabilization and a concrete 15 step curved front entry needing both stabilization and filling work to be done. It took but a short time to come to the realization that we had made the right decision. They were on time, fully equipped and exceedingly professional. They functioned as a finely oiled machine. Each member was part of the team and each seemed to know his job almost without verbal communication It was a sight to behold, not only the quiet efficiency but the willingness to answer all questions without hesitation and to do whatever was needed or required to make us feel that in their minds we were the most important people there. That impression was exhibited by every workman on site. Their work was finished on time and as far as we can see with excellent results. We cannot recommend Terrafirma STRONGLY ENOUGH. This extends to their office administration, Amber Gausnel of Customer Development; Rob Philby, Sales Representative; Wes Johnson, On-site Foreman/Supervisor; his crewmen, Robert, Jason and Mason; and James Cross, Polylevel Supervisor. TO ALL OF THEM WE THANK YOU EXCEEDINGLY!!!
So pleased with the total experience. We were provided with expert analysis of how to achieve stabilization of a concrete slab. Coordination between sales, planning and production was excellent. Technician was very proficient and friendly.
I had an amazing crew. Brad, my job foreman, communicated throughout the process and problem solved a couple issues with me. His crew worked hard and shared their perspectives as the job progressed. We started with a 4 inch slope and we were able to lift quite a bit. Brad and his crew discussed possible impact on the roof, windows, French doors, and concrete foundation of the garage. They did a great job and addressed issues as they came up. They did additional stabilization where needed and hauled away some concrete. They were awesome. I would work with them again. I give them 5 stars ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ Schylar, the foam foreman, was able to come in the next day and fill the gap created under the porch with foam, as well as bring my sidewalk up to meet the porch and level it with the sidewalk. Schyler was great to work with as well. I am disappointed in the sales technician that evaluated the job. He failed to notice that one side of the front porch was sitting on the foundation and how the porch was going to be affected by the lift. He also failed to notice or consider that I have a flat roof in the center of my home, surrounded on three sides by a peaked roof. This matters because the lift puts pressure upward that would typically carry over to the opposite foundation. This was not shared with me during the sales process. In my case, this pressure comes down where the peaked roof meets the flat roof which is on an interior wall. There is also the possibility that lifting one side of the foundation can cause the opposite side to need stabilization as well. This was not shared during the sales process. I give the sales technician one star ⭐️. When I shared these concerns with David, the field supervisor , I was left with the impression that it is just the way they do business.
Had a fantastic experience with Jaden Torson at Terra Firma! They did a superb job fixing the concrete pad at the back of our house. Professional, efficient, and the quality speaks for itself. Highly recommend their services!
The work was done in two days. The problems with the very heavy concrete problems was addressed, and it does look much better which is appreciated. Jeramie was good, worked so hard. Jason did the review before it all started, very easy to work with. It does look much better, it was worth the expensive costs. Thank you!
Our problem was that our front yard had settled, taking parts of our huge concrete front porch and sidewalk down with it. We watched the cracks in the porch get wider every year, and the sidewalk sloped down and away from the house. TerraFirma evaluated our situation and explained what was happening around our house. Then they gave a very detailed explanation of how they would make the repairs - even what they could and could not do - complete with a video demonstration. The young man who showed up to do the work was very courteous and professional. It was fascinating watching portions of our porch and sidewalk being raised up, leveled, and the gaps coming together. We are very pleased with the end result and have recommended TerraFirma to others.
TerraFirma was the third company to give us an estimate and the price quoted fell in the middle. Since Gloria liked Richard the best, we went with them. Due anticipated permitting and scheduling timelines we were not expecting work to commence until roughly mid July. As it turns out, we caught a couple of lucky breaks and Shea was able to get things going 1-3 June. Ryan and crew arrived on the morning of this year's so far hottest day. After he gave me a quick run-through of what they were going to do, they got to it. Throughout the entire project they were the picture of competence and professionalism. When they left this morning it was almost as if they'd not been here at all. The concrete that had to be removed was replaced and will blend in quite nicely. The mulch and gravel were raked back into position and every scrap of debris was removed. We couldn't be more pleased with the company and the crew.
The whole job went smoothly. Katie did a god job communicating as project manager. Mike was quick and efficient with the concrete slab void filling. Tim, Chris and Jonathan were all very professional and expertly got the French rain and sump pump installed. Very happy with all the work done.
The crew were on time, introduced themselves and made sure that we were all on the same page as far as what they were doing. Lifted the back patio up and leveled the sidewalk to martch. Looks great! Did a good job of cleaning up. I would reccomend them for any type of concrete lifting. Thanks guys!
