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.

We recently had foundation work completed. The crew was on time every day and worked hard to keep a very dirty job and their traffic through the house to a minimum. The crew chief, Robert Busch, was amazing. Telling us what was planned for the day, any unforeseen problems, and giving us a recap of what was completed daily. We could not have had a better experience with his communication and hard work. Everyone was respectful and friendly. I also thought that the evaluation and estimate experience was positive. Jim communicated clearly and we never felt that work being suggested was unnecessary. He explained clearly and showed us pictures of what was going on under the house.Hope we never need them again, but would use them in a flash.

I can’t praise Bay Area Underpinning enough! Everything from their support team, to their customer service, and the quality of their work has surpassed my expectations. I’ve used other foundations companies in the past and they weren’t great for many reasons – Bay Area Underpinning has none of the challenges I’ve experienced elsewhere, and massive positive upsides! Would highly recommend!
