What Causes Settling Concrete?

Concrete slabs are known for being strong and durable. So it can come as a surprise when they eventually crack. Unfortunately, cracked, sunken, or voided concrete is more common than you might think.

Settling concrete can happen for a number of reasons, from environmental impact to accidental damage. Understanding some of the causes can help you prevent settling concrete in the future, reducing the need to replace or repair your concrete.

What Are The Biggest Causes of Settling Concrete?

Machinery Damage

One of the obvious causes of damaged concrete is machinery. If the machinery is regularly parked over concrete, it can compact the dirt beneath. This leads to cracks and other damage. Dropping large objects on the concrete can also cause damage.

Erosion

Damage due to erosion can happen to concrete. This is usually as the result of environmental factors, but can include animals or sustained impacts over time. Erosion can take a long time to affect concrete, but once the concrete cracks, the damage can be terrible.

A Change to Soil Moisture

Changes to the moisture content of soil can also cause concrete to settle. If the soil either becomes too dry or too damp, it can affect the foundation of the concrete, causing it to sink and crack.

Environmental Damage

Weather can have a huge impact on concrete. Periods of heavy rain, cold or hot weather can all impact your concrete, causing it to crack. It can be difficult to predict the weather, which means concrete settling can happen unexpectedly.

With various reasons why concrete can settle, it’s important to know where to get help if your concrete becomes damaged. Repair or replacement can help bring your concrete slabs back to life, so get in touch with experts today.

Common Areas That Need Concrete Lifting, Leveling, and Repair and How to Fix Them

Sunken, cracked or uneven concrete is a common issue that frequently affects residential and commercial properties, as well as public areas. Over time, concrete slabs can move, sink or be subject to damage.

Although concrete could be replaced, this is a costly and labor-intensive process. A more efficient and cost-effective option is concrete lifting using polyurethane form. Commonly used in areas that are prone to concrete damage, polyurethane lifting is ideally suited for garages, sidewalks, pool decks, patios, driveways, and pedestrian areas.

Concrete slabs are frequently used in high traffic areas, which means they are subject to significant and consistent pressure. Despite their durability and strength, ongoing use affects the positioning of slabs. Furthermore, movement of the soil underneath the slabs can contribute to sinking or heaving. Due to this, there is an increasing demand for concrete repair.

How Does Polyurethane Foam Work?

Formulated to facilitate swift and effective concrete slab repair, polyurethane foam can be used to lift sunken concrete and realign it. This ensures walkways and surfaces remain even and safe to use, regardless of whether they are situated in public areas, commercial premises or residential lots.

With polyurethane foam concrete repair, you will no longer need to replace concrete slabs once they become misaligned. Instead, they can be effectively leveled and lifted with custom polyurethane lifting.

To achieve this, polyurethane form is injected underneath the concrete. As a result, the slabs are lifted with precision and the concrete is repaired safely, quickly and cost-effectively.

Mudjacking vs. Polyurethane Foam Debate

PolyLiftADMIN Blog mudjacking, polyurethane

Mudjacking vs. Polyurethane Foam, there’s the big question. Which one should you use and why? Well, here are some arguments for and against both, so let’s see which one wins:

Mudjacking

Pros

Traditional mud jacking can achieve compressive strengths of 2,400 PSI by adding cement or combining cement with lime or sand.

Cons

Traditional mud weighs 100-150 pounds per cubic foot, which is very heavy compared to Polyurethane Foam.

Polyurethane Foam

Pros

Polyurethane Foam weighs 3-4 pounds per cubic foot, which is much lighter than mud, making it much less likely to overburden unstable soil.

Polyurethane will make the end results far more attractive, especially when it comes to the residential market, as there is a smaller injection hole from this process.

US Departments of Transportation are opting for polyurethane concrete lifting for sagging bridge approaches or for removing dips in highways; this is because of the material’s lightweight characteristics that do not overburden the soil.

Cons

Polyurethane has a compressive strength of around 80 to 100 PSI, and for many, it is preferable to pump a higher compressive strength material than the existing sub-base.

Conclusion

While many are in favor of mudjacking, especially when weight is not a concern, there is no doubt that polyurethane foam is a lighter, safer, and long-lasting option that doesn’t post a risk to creating further problems due to weight.

Polyurethane may sound toxic, but in fact, it is extremely safe and actually good for the environment compared to different options. Leveling a concrete slab by injecting polyurethane foam won’t do any harm to the environment, it could actually do some good and here’s why:

Better Indoor Air Quality

If your garage is in need of concrete repair, make sure you keep the air quality in mind. Many options are dangerous. However, polyurethane foam is non-toxic and is a far better option to level your house with than toxic substances that may include carcinogens, which can cause difficulties in breathing and also increase your risk of getting cancer.

It Generates Minimum Waste

Repairing concrete with polyurethane foams results in less cost and waste than other options. While some physical materials are used, our experts ensure a quick job without compromising on quality. There is also more control over this process, which means that there is less damage to surrounding areas.

It Results In A Cleaner Job Site

Following on from that, this method of concrete leveling reuses and recycles various products that are long-lasting, which means that there is minimal use of materials. Then, the holes that are drilled are small, and there aren’t many of them, which means that the end result is cleaner. As well as this, no heavy machinery is needed so the disturbance to your life is minimal.

It Stabilizes The Soil

Polyurethane concrete services react with the soil beneath, which stabilizes it in the ground and protects it from erosion and sinking.

Essentially, polyurethane is not only safe for the environment, but it is economical, practical, clean, and quick.

How Polyurethane Concrete Lifting Works

PolyLiftADMIN Blog concrete, leveling, lifting, polyurethane, repair

There is no denying that cracks in your concrete can be a cause of trips and hazards. They can increase wear and tear on tires and make snow removal very difficult. It can look unsightly as well!

You can combat settled and sunken concrete by leveling it using polyurethane foam. The polyurethane concrete raising process is quick and efficient. Here’s how it works:

Before you level

There are a few things you need to consider and do before concrete leveling takes place.

Get an estimate

The first thing to do would be to get an estimate. Once you schedule an estimate, a technician will come out to inspect your settled concrete.

Schedule your concrete leveling

After receiving your estimate you can schedule your concrete leveling repair.

Day of Service

Unlike replacing your entire sidewalk or driveway, raising your concrete with polyurethane takes only 1-2 hours. The process is simple and mostly mess-free.

Drilling – It begins with drilling a few ⅝” holes into the concrete slab that is being raised. One of the benefits of choosing polyurethane concrete raising over mudjacking is the size and the number of holes drilled into the cement.

Filling – Using an injection gun and a tapered delivery port, polyurethane foam is pumped below the sunken concrete. The foam fills the gaps where soil under the slab has settled or washed away.

Raising – Once the polyurethane foam is injected below the concrete, a chemical reaction occurs. It expands and raises the concrete

Cleanup – Once completed, the holes are filled in and all equipment is removed from site.

Using your concrete again

Once the concrete is raised to the desired height you need to allow 15 minutes for the polyurethane foam to cure. Once it has, you can walk and drive on the concrete slab once more.

How To Prevent Concrete Damage On Your Property

PolyLiftADMIN Blog

Whether your concrete is brand new or newly raised, you can prevent concrete settling and forming cracks. There are three things you can try to ensure your cement stays level.

Seal Cracks and Joints

The first thing to consider is ensuring that cracks and joints are sealed properly. If you notice any, use concrete caulk to seal them straight away. If the gaps are large, you can use a backer rod to fill in the gap. Then use the caulk on top to seal it up.

Caulking the cracks and joints in your concrete at the earliest opportunity helps to keep out moisture that can cause washout in your concrete slab. Washout is one of the leading causes of your concrete not settling.

Adjust Downspout Location

An easy way to prevent concrete settling is to adjust the location of your downspout. A great tip is to ensure that your downspouts are at least 5 feet away from the sidewalk, driveway or patio.

Pack Surrounding Soil

To avoid water flowing under the cement, you need to ensure that any open sides of your concrete slabs are tightly packed with soil. The soil needs to be well compacted into the sides to avoid any water getting in.

Getting new concrete poured?

One of the best ways to prevent concrete settling starts with when the cement is poured. You need to ensure that there is a tightly compacted base below below the cement which can help combat against the following:

Soil compression
Washout below the concrete
Changes in soil moisture

What if concrete has already settled?

If your concrete has already settled, the best solution is to raise it by using polyurethane foam. While replacing the concrete may be your first thought, raising the concrete is actually less expensive and timely than it would be to replace it.

The Challenging Craft of Concrete Repair

PolyLiftADMIN Blog concrete, craftsmanship, repair

When you think of people that you would call to fix things that are in need of repair, would you consider them an artist? Do you feel that what they do is a craft? You most likely consider them experts in their field, technicians, and professional in what they do, but artists or craftsmen seem to best describe a job role that is more creative. Wouldn’t you agree?

However, repairing concrete and using polyurethane isn’t something that can be captured in an instruction manual. Truth be told, it is an absolutely science, and is also very much an art. One that requires experience-based judgement, creative problem-solving, patience, dedication, and serious attention to detail.

Although there is a need for specific types of technology to help with the process, this again needs skilled people to manually be able to use them. This element can be done by following instructions, but implementation will always require the repairer to know what areas of the concrete that needs the attention. In terms of repair, lifting and cracks.

Among the many things that include the professional and experts making judgements in terms of the repair, the concrete requires them to assess it. Craftsmen are very much focused on attention to detail, and concrete repair requires a level of precision and being exact, while understanding that each repair will not be the same. This is where a sense of judgement and experience will come into play and be a huge factor in the overall concrete repair.

Polyurethane Sidewalk Leveling

PolyLiftADMIN Blog

Sidewalks are usually made from slabs of concrete lined across a surface like soil. While effective, wear and tear or poor tree-root growth can cause the sidewalk to become unbalanced. This results in uneven sidewalks that people might trip or stub their toes on, and it also looks visually unappealing. If your sidewalks need a boost, read on for more information about polyurethane sidewalk leveling.

Sidewalk Leveling Options

A common way to repair your sidewalk is to simply use concrete. This usually involves pumping a mixture of water, concrete and soil to fill in voids and level the concrete slabs that line your sidewalk. Unfortunately, this doest fill evenly. It often makes things worse and will continue to demand maintenance in the future. If the concrete is not pumped correctly or too much is used, then it will still lead to an unbalanced sidewalk.

Modern Polyurethane Sidewalk Leveling

Using concrete is an outdated way to level a sidewalk. A more modern approach would be to use polyurethane foam, also known as PolyLift, to repair your uneven sidewalk. This is a foam material that is injected underneath your uneven slabs of concrete. It will then expand and harden within a few minutes, leveling your sidewalk and providing extra strength rapidly. It helps to balance your driveway and is an easy way to repair your sidewalk when applied correctly.

Polyurethane foam is also environmentally-friendly, making it a green way to repair your sidewalk if you’re conscious about the environment. It also doesn’t take 24 hours to set like concrete, meaning you don’t need to block off the area and prevent people from walking past.

How to Level Your Driveway With Polyurethane Foam

PolyLiftADMIN Blog

Concrete is the most popular material to use for driveways. However, due to poor soil conditions or drainage problems, it can often become unsettled and look visually unappealing. If left in that state, it could cause accidents not just for you, but for others as well. As a result, it’s a good idea to learn about polyurethane driveway leveling. This article will provide more detail.

Traditional Driveway Leveling

The most common albeit dated method of filling and levelling a driveway involves pumping a mixture of water, soil and concrete to fill voids. The concrete can take up to 24 hours to settle, meaning you’ll need to wait a long time before you can use your driveway again. If you disturb the concrete as it settles, then you may end up with an uneven surface that needs to be re-levelled again.

Polyurethane Driveway Leveling

In comparison, polyurethane foam, or PolyLift, uses a foam material that is injected underneath a sunken slab of concrete. The foam causes a reaction that expands the foam, hardening it within minutes and lifting the slab to fill any voids. The foam is waterproof and doesn’t break down under normal conditions, meaning it helps to level your driveway and keep it that way.

It’s an environmentally-friendly and affordable way to level a driveway without the need for future maintenance. It will protect not just your driveway, but also ensure that the foundation of your home is protected from issues like poor drainage and excess water flow. If you’re looking for a solution to your sinking driveway, don’t hesitate to give us a call today for more information. 844-765-9872 or contact us via the web.
