Sunken Concrete is Both a Safety Hazard and a Liability

Sunken concrete slabs are both a trip hazard and a liability. If someone gets injured on your property, you could end up getting sued. Therefore, this isn’t a repair you want to postpone for long.

We are able to lift sunken or settled concrete slabs in Napa, CA including, but not limited to…

Benefits Of Concrete Lifting Via Polyurethane Foam Injection

The benefits of concrete lifting – also known as slabjacking or polyurethane foam injection – are many, including:

  • It’s a solution that lasts. The extremely lightweight nature of polyurethane foam means it won’t add more weight to the soil. Other ways of lifting concrete – for example, mudjacking – might raise the slab temporarily. However, the cement slurry used to lift the slab weighs quite a bit. If the soil was having trouble supporting the concrete before, adding more weight to it isn’t going to help.
  • It’s easy on the budget. When compared to digging up and replacing a slab, concrete lifting via polyurethane foam injection is a cost-effective solution.
  • It’s a quick and easy repair. Polyurethane foam injection usually only takes a few hours, tops, and you can use the slab immediately after the repair is complete.
  • It’s lightweight. Polyurethane foam lifts concrete without burdening the soil with additional weight.
  • It won’t harm the environment. Polyurethane foam won’t leach harmful chemicals into the soil. Therefore, it’s a green solution you can feel comfortable using on your property.
  • Even concrete just looks good! Sunken, uneven concrete is an eyesore.

What Causes Concrete Slabs To Sink Or Become Uneven?

Concrete slabs sink and become uneven for a variety of reasons including…

Drainage problems. Too much water in the soil under the slab can cause erosion and lead to voids.

The soil isn’t strong enough to support a concrete slab. Soils are not all alike. Some don’t have the ability to hold up a heavy slab.

Expansive soil. Expansive soil expands as it absorbs water and then shrinks as it dries out. Over time, this swelling-shrinking cycle can eventually lead to an uneven slab.

Invasive tree roots. You can probably guess how this happens. The roots push against the slab and cause sections of it to become uneven.

What are the Different Ways to Lift a Concrete Slab?

Traditionally, uneven concrete slabs were repaired either via “mudjacking”, or by removing the uneven slab and pouring a new one. Both these methods were less than ideal and that’s why, today, almost all sunken concrete slabs are lifted via polyurethane foam injection.

Mudjacking

Mudjacking uses a cement slurry to raise the slab. The problem here is the weight of the slurry. It’s heavy because it contains cement. If the soil was already struggling to hold up the slab, you shouldn’t be adding additional weight to it. That could cause it to sink even more.

Concrete Replacement

A sunken concrete slab can also be dug up and replaced. However, this fix is both time-consuming and expensive. Newly-poured concrete takes time to dry and while this is happening, you won’t be able to use the slab. Also, if the soil was struggling to hold up the old slab, it will also struggle to hold up the new one.

Whatever you do, don’t add fresh concrete to the top of a sunken slab in order to even it out. The additional weight will almost certainly cause it to sink even deeper into the soil.

Polyurethane Foam Injection

Polyurethane foam injection (also known as ‘’slabjacking’’) is a cost-effective and minimally-invasive method for lifting sunken concrete. The extremely lightweight and rapidly-expanding foam is injected under the sunken slab and this lifts it back up. It’s a quick repair, and when it’s done you can start using the slab again right away.

Within a few months of buying our first home, we noticed some troubling signs: bedroom doors swinging open or closed on their own, “bubbles” and creaks in sections of the newly renovated floors, and significant cracks splitting the concrete in our garage. Although two general inspectors assured us that our house was level, we reached out to Bay Area Underpinning (BAU) for a more detailed assessment—and we're so glad we did! Inspector Christopher Murray conducted a meticulous inspection with radar equipment. While technically our house was level, Christopher uncovered that our foundation was sinking by inches in multiple areas, explaining the issues we were experiencing. Though the news and associated repair cost were a bit daunting as new homeowners, Christopher’s knowledge, professionalism, and clear answers to all our questions reassured us that we were in good hands. With confidence, we decided to proceed with BAU for the repair. Fredy Mora and his crew did exceptional work with the demo of the old concrete slabs and the prep for lifting, working quickly and efficiently. Fredy’s positive attitude made the process smooth, and his team was thorough and dedicated from start to finish. A special thank you to our lift project manager, Kevin Gaeden. Kevin was an outstanding communicator, keeping us fully informed and addressing every question promptly. His attentiveness made a huge difference throughout the project, and we felt reassured every step of the way. Esteban Ibarra, a crewmember on the lift team, also did superb work, handling the hands-on details with skill and care. Both Kevin and Esteban even went above and beyond, taking time to fix a jammed bedroom door that had shifted with the house lift. While foundation issues are never easy, we couldn’t have asked for a better team. We’re incredibly grateful to Bay Area Underpinning for their expertise, professionalism, and exceptional service. Thank you, BAU!

Thank you Bay Area Underpinning for saving the day! I was in a challenging and prolonged situation since going into contract with EagleLift for the stabilization/lift for my house. After a long permit process and continuously delayed start dates, I was informed that EagleLift had been acquired by Groundworks and I’d have to wait a few more month before any progress could happen. It was a deeply frustrating process but the EagleLift team was able to connect us with Bay Area Underpinning (another Groundworks company) who were able to take over and expedite the project. To my surprise, James T. from BAU reached out quickly and assigned a team to come to my house within a week! The team that ended up working on the house, specifically Ish, John and Abel were exceptional. They were diligent, knowledgable, friendly and deeply considerate. They are truly pros who knocked the project out in no time which was reassuring since I was nervous that this project was gonna stretch into the rainy season. My house feels so stable now (minimal cracks too) and the considerable slope is now practically nonexistent! Thanks a lot James T., Ish, John, Abel and the BAU team for taking really great care of us.
