Should I Fix My Sunken Slab?

When a concrete slab begins to sink, it not only looks bad, but it can be a sign of a serious problem. You must have a professional take a look to see what is causing the slab to sink. They’ll not only be able to raise the concrete, but also fix the underlying problem.

Regardless of the location of your slab, it is worth fixing. A concrete slab in your basement, patio, driveway, sidewalk, or garage are all important surfaces and need to be safe and stable. 

Cracking and Sinking is a Bad Sign

Should you repair your sunken concrete slab?An uneven slab can be a tripping hazard, which is the #1 cause of insurance claims around the home. The slab is not going to heal itself, even if you hope that it will just go away or that no one will be injured. So, before someone gets hurt and sues you, have a professional inspect the slab and repair it. 

Lifting a slab correctly and safely is not a DIY project, it takes special equipment and training to do the job right. A slab will crack and sink when the soil beneath it is not supporting it. This can be caused by erosion, soil that wasn’t compacted, oversaturated soil, and other events occurring below the surface.

Causes of a Sunken Slab

As we stated above there are a few reasons why a concrete slab may sink.  The soil is not doing its job of supporting the concrete. The weight of the slab may be compressing the soil, causing the concrete to sink. Another cause may be soil erosion. If the soil beneath the surface is washed away, the slab will sink into the void that is left behind.

Many people believe that they have to break up the slab and start over with a new concrete surface. The professionals at Airlift Concrete Experts advise you to find another option. Breaking up and replacing concrete is expensive, messy, and time-consuming. On top of these reasons, if the underlying soil problem isn’t addressed, you’ll just have another sunken slab in a short amount of time.

Sunken Slab Solutions

Airlift Concrete Experts has a solution for your sunken concrete that costs less than demolition, involves less equipment, takes less time, and is more effective than breaking up and replacing the slab. The solution is called polyjacking and has been used by highway departments across the country for years. It is now being used more and more for residential applications as the cost has come down and the contractors have become more experienced with the method.

Polyjacking involves drilling a few small holes (5/8″) into the concrete surface. Polyurethane foam is injected into the holes, the foam expanding beneath the surface. The foam fills voids, compresses the soil, and lifts the concrete to within a fraction of an inch of the desired height. 

The foam hardens within 15 minutes of injection, allowing you to use the surface quickly, instead of having to wait days for new concrete to cure. The hardened foam is water-resistant, so it won’t wash away. Another benefit of polyjacking over mudjacking is that the foam weighs a fraction of what the mud grout weighs. If the soil is already unstable, it doesn’t make sense to add hundreds of pounds of extra weight to the area.

Does My Sunken Slab Need to be Repaired?

Some people may think that a sinking slab is nothing more than something that is unsightly. It’s actually a sign of a bigger problem, in addition to being a tripping hazard and cause for water in your home.

Regardless of where the slab is located, it should be repaired. Homes can have slabs as foundations, sidewalks, patios, decks, driveways and more. Not every crack is a warning sign, but they should be inspected by a trustworthy and knowledgable specialist. When a concrete slab not only has cracks, but also sinks, then you are likely to have a structural problem.

Problems Caused by Sunken Slabs

A sunken slab can be a dangerous tripping hazard. Trips and falls are the number one source of claims on homeowner’s insurance policies. In addition, an uneven slab can damage vehicles, furniture, and other pieces of property. 

If a slab sinks, the water is not going to drain properly from the slab. It can run towards a home’s foundation, causing the basement or crawl space to flood. Water can wash out foundations or erode the soil underneath the concrete surface.

For the safety of the people on your property and the stability of your home or slab, it is important to raise a sunken slab and prevent it from settling again. Polyjacking is an effective concrete repair method for leveling a sunken slab.

Causes of a Sunken Slab

There are a couple of reasons that a slab can sink. It is more common for a portion of the slab to sink than the whole concrete area. 

Compressed Soil

If the soil beneath the slab wasn’t properly compressed during construction, the weight of the slab can push the soil down, allowing the concrete surface to sink. 

Erosion

Heavy rains, broken pipes, and other causes of water flow can wash the soil out from under the concrete slab. The concrete will then sink into the hole, becoming unlevel or breaking.

Best Solution for a Sunken Slab

You may still find contractors that recommend you break up the concrete and pour a new slab. This is expensive, time-consuming, and doesn’t address the problem that caused the slab to sink in the first place.

After wasting the money of demolition and then repouring the concrete then waiting days for the slab to cure, you’ve done nothing to prevent the soil from compressing or washing away. Some shifty contractors may add more concrete to the void, but all that does is add more weight to the weak soil, making it even more likely that you will have another sunken slab eventually.

There is a better solution, one that Airlift Concrete Experts has been using for over a decade: polyjacking or polylifting. Polyjacking eliminates the problems associated with other slab repair methods. Polylifting uses a polyurethane foam that expands, lifting the slab and sealing the underside portion of the concrete.

Expense

Using polyjacking methods is exponentially more cost-effective than demolishing the concrete. Heavy equipment will be needed to break up the concrete and then to pick up the debris. The equipment, personnel, and time for the demolition cost money. Then you have to pay someone to pour the new concrete. The dollar signs will be lighting up a contractor’s eyes if you go this route.

Time

The entire polylifting process takes less than an hour to complete in the majority of situations. The process involves drilling fewer and smaller holes than other methods, so clean up takes less time. The foam cures in about 15 minutes, so it’s a race to which is done first: the cleanup or the curing. As soon as they’re both done, you can use your concrete slab again.

Effectiveness

As stated earlier, removing and replacing the concrete doesn’t address the underlying problem that caused the slab to sink in the first place. The polyurethane foam compresses the soil as it expands. It not only lifts the slab to within 1/10th of an inch, but it makes sure the underlying soil is stable. In addition, the foam is water-resistant so it won’t wash away like soil or the slurry used in mudjacking. The foam also fills in the gaps and cracks on the underside of the slab, preventing water from flowing through the slab, undermining the stability of the concrete surface.

Learn More About Polyjacking

Although polyjacking has been around for a long time, many homeowners are unfamiliar with it. If you have a sunken slab, contact a contractor that specializes in polylifting before you commit to demolishing the concrete. Get all the facts and make an informed decision about keeping your family and property safe. A strong, stable slab isn’t something that you should make a rash decision about.

Concrete Repairs in Arkansas

Between the harsh winter and never-ending rain this spring, Arkansas concrete has taken a beating. Airlift Concrete Experts can help you repair your concrete and keep your home or business safe and strong. The clay that covers most of Arkansas can move a lot, depending on the amount of moisture in it. It can expand with too much water and shrink when it dries out. This soil movement can cause concrete to sink, crack, buckle, and more.

Common Problems Caused by Damaged Concrete

If you have any of these problems going on, it is important that you contact Airlift Concrete Experts as soon as possible. A small problem can grow into a large one if left ignored. 

Solutions for Damaged Concrete in Arkansas

Airlift Concrete Experts can restore, repair, and strengthen your concrete slabs. We use a polyurethane foam that will seal cracks, fill voids, and lift concrete. The process is quicker, easier, and more effective than other methods, making it the best choice for concrete repair. 

The polyjacking solution uses one vehicle, so you won’t have to worry about a bunch of equipment taking up space or trampling your landscaping. The process involves drilling holes that are around 5/8″ in diameter into the slab. Other methods use holes that are around 3″ big. Polyurethane foam is injected into the holes and under the slab. The foam expands, lifting the concrete, filling in any voids, sealing the bottom, and condensing any loose soil. Unlike the slurry used in mudjacking, the polyurethane foam is water-resistant, so it won’t wash away over time. The foam cures in about 15 minutes, allowing you to use the concrete shortly after the repair. Other methods can take days or weeks before the surface is usable.

Once the area is cleaned up, we’ll get out of your way and you get back to your home life or business with a strong and stable concrete slab.

How Polyurethane Solutions Can Help You

Even though the use of polyurethane has been around for decades, many people aren’t familiar with the product and all of the solutions it offers for home and business repairs. Companies like Airlift Concrete Experts has the tools and experience to strengthen and stabilize your property with polyurethane foam. 

Your home or business is probably your biggest investment, make sure the repairs that are done are going to be effective and last a long time. 

Places to Use Polyurethane Foam

polyjacking a concrete slabThere are so many locations and surfaces that can benefit from polyjacking:

  • Basements
  • Driveways
  • Garages
  • Parking Lots
  • Patios
  • Pool Decks
  • Sidewalks
  • Warehouse Floors

The polyfoam can lift all kinds of concrete slabs, regardless of whether they are residential or commercial. The process is easy and quick, compared with other lifting options. The polyurethane foam is strong and can lift different types of concrete surfaces.

Steps for a Successful Polyjacking Project

The basics of a successful polyjacking project are relatively simple. This is one of the many reasons that contractors and property owners like to use polyjacking for their concrete repairs.

concrete solutionsThe first step in the process is to clean the concrete surface. The contractor will remove dust and debris from the slab, making sure the area is ready to be repaired.

Next, the concrete will be prepped. This involves the contractor determining where the holes for the foam injection need to be. The lifting professionals will mark and drill the holes where they will be the most effective. The holes are much smaller than those used in mudjacking, usually a 1/2″ to 3/4″ in diameter. Mudjacking holes can be 2-3″ wide.

After the slab is ready, the polyjacking experts begin injecting the polyurethane foam beneath the slab. The foam will begin to expand, lifting and sealing the concrete. As the foam is injected, the installers will monitor the concrete level, raising it to within a tenth of an inch of the desired height. 

Once the slab is at the desired height, the technicians will remove any extra foam and then patch the holes. It takes about 15 minutes for the foam to set and the repaired slab can then be used.

Strong and Stable Slabs

 

free quote for polyurethane lifting

A concrete slab that is raised with polyurethane foam should remain level for a long time. The foam is water-resistant so it won’t erode like the mud slurry used in mudjacking. In addition, the foam creates a waterproof seal on the underside of the slab. Cracks are closed and water can no longer cause any damage to the surface. The foam is much lighter than the slurry, so once the foam condenses any loose soil, it won’t cause the slab to sink under the weight of the muddy slurry.

The process doesn’t require heavy equipment, so the surrounding area won’t be trampled and the area won’t be cluttered with vehicles and equipment. Once the process is done you can go back to work or using the surface within a few minutes, so the interruption to your day will be minimal.

Concrete Solutions

Most people take concrete for granted. We drive on it, walk on it, and build on it. As long as it does its job, we don’t really think much about it. 

However, when there is a problem with the concrete, we think a LOT about it! Concrete can sink, crack, or crumble. When it is no longer safe or usable, it’s time for a concrete expert like Airlift Concrete Experts, LLC to come in and offer some concrete solutions to restore the strength of the cement.

Exterior Concrete Leveling

Outdoor concrete surfaces can range from patios and sidewalks to driveways and roads. All have different jobs to do and different stressors that they have to deal with. The surfaces can become cracked or uneven, leading to tripping hazards or damaging equipment. The damaged concrete can allow water to penetrate into places it shouldn’t, causing even more problems. It is important that you repair damaged exterior concrete as soon as possible.

One of the best solutions for damaged concrete is through the use of polyurethane foam. The foam is injected underneath the concrete, causing the slab to rise to the desired level and giving the concrete a stable base. The foam is waterproof, so it can’t wash away and it seals the bottom of the slab. Additionally, the cure time is around 15 minutes, so in the time it takes to clean up and put away the equipment, your concrete slab will be ready to be used.

Interior Concrete Leveling

Whether your home or business is built on a concrete slab or it has a basement, there is a concrete floor that is supporting the structure. If the concrete is damaged, the building is in danger of being damaged even more. The structure can be weakened or water and pests can enter the building. 

Airlift Concrete Experts has a concrete solution that is perfect for interior concrete problems. Polyjacking doesn’t use heavy equipment, so it’s easy to do repairs inside a home or business. There is no demolition needed and only a few small holes are drilled into the concrete surface. The foam is then injected through the holes to the underside of the concrete. Cracks will be sealed from below and the bottom of the slab will be water-tight. Once the slab is restored, the holes are filled and the slab is ready to be used in a short amount of time.

Commercial Concrete Solutions

Commercial properties may have some unique situations when compared with residential structures. Airlift Concrete Experts can provide stabilization, raise concrete slabs and footings, seal cracks, and filling voids.

There are several causes for a foundation settling, but the solution is usually the same. Soil can compress or weaken or water can erode the soil underneath the slab. Water can also expand, pushing against the concrete, causing cracks and shifting. A concrete expert will inspect the property and determine not only the cause of the problem, but what the best solution is. 

Many people try to seal cracks themselves, but that is a temporary fix that can actually hide underlying problems. By using polyurethane foam, we can seal the bottom of the slab and fill in any voids that are located there. The foam won’t wash away and is lighter than the mudjacking slurry that is used by other methods. The foam will also compress the weak soil, making it more stable. When the foam expands, it will also cause the slab to rise to the desired level. We’re able to control the foam so that the slab is within 1/10″ of the desired height.

Polyurethane Foam is One of the Best Concrete Solutions

How Long Does Polylifting Last?

When it comes to any type of repair, most people want to know if the fix is going to last or are they going to have to repeat the process again in a short amount of time. Making sure a repair job is effective and long-lasting is one of the first things you want to look into when considering a solution. This applies to concrete lifting, too. Why would you waste the time and money to lift your concrete if it is just going to sink again?

The lifting solution should last just as long as the concrete surface. The trick is to not only lift the sunken concrete, but to remedy the cause of the sinking.

What’s Going On Under There?

polyliftingYou can patch a crack or lift a concrete slab a thousand times, but if you don’t take care of the cause of the problem, you’re just going to keep repeating yourself, while throwing money out the window. The majority of the time, the soil underneath the slab is either weak or missing. The polyurethane foam that we inject under the slab expands, filling the void, compressing the weak soil, and sealing the bottom of the slab against water and moisture.

By keeping the soil stable and strong, the concrete won’t move or sink. It takes an expert to find the right locations to inject the polyurethane foam, in addition to the right amount. If the holes aren’t placed in the correct location, the polyfoam won’t fill in the correct spots under the slab. 

There are several reasons why the soil under a slab can fail. If it wasn’t properly compressed during construction, it will settle from the weight of the slab and traffic above it. If there is a drainage problem, the soil can erode or wash away, leaving a void underneath the slab. Earth is strong, but if it is weakened or absent, it won’t be able to do the job. The polyurethane foam can compress the soil, making it supportive of the slab. The foam can also expand, filling in the empty space where the soil left. Once the foam hardens, it is stronger than the soil and water resistant, so it won’t wash away while also holding up the concrete slab.

You Can Help Yourself

There are a few things you can do around your property to help keep your concrete slab stable and undamaged. These solutions are relatively easy and inexpensive (especially when compared to repairing or replacing a concrete slab). 

  • clean out guttersCheck that your downspouts are draining at least 5 feet away from the slab. This seems to be a common problem. People are pretty good about making sure that the drains empty away from their foundations, but don’t think about sidewalks, driveways, and patios.
  • Keep gutters in good condition. If the gutters are clogged or damaged, the water running off of the roof isn’t going to drain properly. Replacing gutters can be a hassle, but it will protect your home or business, along with the surrounding property.
  • If there isn’t backfill around the edge of the concrete slabs, you may want to add it. This will keep the water draining away from the slab, in addition to preventing animals from burrowing underneath the concrete. 
  • Reapply caulk or other sealants to the joint between concrete slabs. This will prevent water from entering from above in addition to protecting any rebar that may be connecting the two slabs.

If you don’t take these steps, the concrete lifting solution will just be undone and you’ll have to do it again. And again. And again. If you help protect your concrete, the polylifting will last longer, providing you years of concrete support. We’ve had projects that moved less than a fraction of an inch over a decade and also been called in to fix another contractor’s work less than a month after they completed the project. It almost always comes down to drainage around the impacted area. Take the time and effort to be proactive and you will have a much better success rate.
