Fixing Concrete Voids Before They Cause Massive Damage

raise the garage floor

Perhaps you are looking to raise the garage floor. Or maybe you just suspect that there is trouble around the corner with your concrete driveway. Regardless what type of concrete raising or concrete service you are looking to perform, it is important to know how to recognize when you have a potential void in your concrete that would require filling.

What is a Concrete Void?

The first thing to understand is that voids in concrete are not visible. Unlike traditional crack repair (which is very visible), a void in the concrete can build up over time, eventually causing massive damage to the surface of the concrete, requiring large repairs. One of the reasons voids are not detectable by surface damage at first is that concrete is very strong. Average concrete can withstand about 3000 psi (pounds per square inch), and some concrete has a strength of over 20,000 psi. Because of this, the concrete will withstand enormous amounts of pressure and stress, until eventually the entire slab just cracks. When it does crack, the crack is usually massive.

The most high-tech solution is to use a GPR, or ground penetrating radar. GPRs are used by contractors to detect voids or holes under a concrete slab. If you are looking to raise the garage floor, it could be because you have a void in your concrete. Garage floor voids are difficult to detect without a GPR. Without a GPR, you might be able to detect a void by driving into your garage and listening to see if you can hear a shallow or hollow sound as you drive over the concrete. Sometimes there will also be tiny cracks throughout the concrete, or sometimes you will be able to detect a shift or tremor in the concrete. All of these are signs that you should look to raise the garage floor and fill the void.

How to Fill Concrete Voids

Filling concrete voids can be tricky. Because the void typically isn’t accessible through a visible crack (yet), there are only a couple of options. For small slabs, such as a sidewalk, it is possible to pack under the slab with gravel or some other material to keep the void from damaging the concrete. For larger slabs, such as a patio or garage, this isn’t usually an option.

One of the best methods for large slabs is to use some sort of expanding polymer substance, such as Polyurethane. Polyurethane can travel several feet through openings on the side of your slab to find and fill the voids underneath. This can sometimes be enough to prevent any further damage to the slab, even if you are looking to raise the garage floor.

When to Hire a Professional

Concrete can be expensive, and so is fixing it. Sometimes, because of the nature of a slab (especially in a garage), it can be difficult to access places where you can easily fill a void using Polyurethane or another expanding substance. Even if you want to raise the garage floor, you will need to fill the voids underneath in order to ensure good concrete strength and durability. There are plenty of options for slab jacking and soil cement stabilization that can be done professionally to ensure that your concrete is secure and solid for years to come.

Before you sell – Fix the foundation, before the inspector fixes your pocket book!

Are you getting ready to put your home on the market, but worried about what they might find during the foundation inspection? Potential home buyers want to make sure that they are buying a property that is built on a strong and lasting foundation. If you know that your foundation has structural or cosmetic damage, now is the time to take action and hire pressure grouting contractors.

Pressure grouting contractors can maintain or improve your home’s value by repairing foundation issues that are small or large. Pressure grouting is a shoring method that fills, solidifies and lifts target areas in the soil beneath your home.

This concrete raising process improves the load bearing capacity of your foundation. It will lift up and level out any uneven or sunken concrete slabs. The soil cement stabilization process protects your foundation against future problems from shifting or moving earth.

Concrete raising is not a new process. Originally called slabjacking, this minimally evasive technique has been used for almost 100 years. In addition to leveling your foundation. it can be used to fill concrete voids in driveways, for crack repair and to raise the garage floor.

Pressure grouting is very versatile. It can be used for new construction as well as existing construction. It can be used to fix an existing problem or to prevent a future problem. Concrete professionals consider pressure grouting as a very cost effective measure.

The reason you are experiencing foundation issues, may have nothing to do with the home itself or previous maintenance. There are certain geographic regions that are known to have softer, more loosely packed soils. When soil structures are weak, the earth can shift and cause structural problems.

There are many reputable and experienced pressure grouting contractors available to help you. These concrete service professionals will visit your home, complete their own detailed inspection, and then recommend the right repairs for your unique problems.

When you put your home on the market you can show buyers a copy of your work order to prove that you resolved any existing issues. This will give potential home buyers piece of mind.

Caulking and why it is necessary

1-855-752-2522

A question we get often is “Can you seal my cracks and joints on my concrete?” and yes, the answer is yes!

There are many different reasons why you would want to make sure the joints of either your driveway, walkway or patio is sealed up. First reason we recommend caulking those joints are to make sure there is no water from either rain fall or sprinklers that can get down through those cracks and or joints to cause erosion which then leads to voids under your slabs leaving the concrete unstable and vulnerable to crack due to pressure and more likely to settled.

Another reason our estimators would recommend caulking these areas would be it gives the concrete a nice finished look. (some before and after photos attached at end)

There are many benefits from caulking the joints and cracks of your concrete but by giving us a call at Slabjack Geotechnical we can point you in the right direction to get your concrete in the best shape!

Raise Or Replace? How To Deal With Damaged Concrete

concrete leveling

Although concrete is an exceptionally durable material, it can still incur damage. From cracks and chips to uneven slabs, you may be wondering whether it’s worth the repair, or whether you should just rip it out and replace the entire slab. Though it may sound easier, replacement always costs more — in both time and money — to do; concrete raising is often the better choice. Let’s find out why.

  • It’s more affordable. Concrete slabs need to be utterly destroyed before they can be replaced. This means that a crew must be hired to demolish, remove, and discard the old pieces before moving on to stabilize the foundation below and, finally, repour and let cure the new cement. As you can guess, this process takes a lot of time, manpower, and materials — all of which you’ll be forced to foot the bill for. Additionally, new concrete takes two to seven days before it can be walked upon; raised concrete can be used immediately. By relying on concrete raising, you can lower your overall costs and save a remarkable amount of time.
  • It has a minimal impact on the surroundings. Large and heavy equipment is often required to demolish and repour the slab. If work is being performed in your place of business (such as a warehouse or a factory), this can disrupt your daily operations and potential harm the landscape surrounding the slab. Conversely, concrete leveling equipment is parked offsite, and can get to hard-to-reach places without changing your busy schedule; you don’t work around the crew, they work around you.
  • It is safer. If the work is being performed in a commercial building, concrete replacement creates a lot of time for employees, tenants, and any passersby to fall subject to injury. Because the concrete leveling process is so quick (generally between two to three hours, depending on the severity of the problem), these people — yourself included — the risk of injury is greatly reduced.

Concrete raising (originally known as slab jacking or mud jacking) can turn a multi-day replacement job into a lazy afternoon. When you compare the resources and risks, there is simply no competition: whether you’re looking to raise the garage floor or fix the sidewalk in front of your office building, concrete leveling is the only way to go.

4 Reasons Why You Should Consider Concrete Floors

concrete grinding

Concrete is used more than any other manmade material in the world, and for good reason. A surprising number of our roads, buildings, and varying structure rely on the sturdy combination of cement and aggregates to hold their shape and form in a wide variety of conditions. Whether you’re installing a driveway or a showroom floor, you’ll want a material that can stand up to heavy loads, varying temperatures, and constant traffic. Let’s take a look at four reasons why concrete is the perfect material for the job.

 

    • Cost: Sealed concrete is remarkably affordable, and can cost just a few dollars per square foot installed. Even the long-term costs are lower than traditional flooring options; as a simple surface — which can be polished to the Nines thanks to concrete grinding services — it is easy to clean and care for, especially when compared to other options such as tile or stone.

 

    • Durability: The average concrete strength is around 3,000 psi, but some concrete can reach strengths of over 20,000 psi. If you know that big, heavy vehicles will frequently be traveling across your floors, you want to guarantee that your flooring isn’t going to fracture under the weight. At the same time, concrete grinding can be followed with sealants that keep out oils, fluids, and any other spills that may occur.

 

    • Maintenance: That being said, no flooring material is impervious to damage. With concrete, you have options beyond the expensive replacement of entire slabs; concrete crack repair can be performed through concrete leveling (also known as slab jacking). As the name suggests, this technique can also be used if your slabs have settled and become uneven.

 

  • Appearance: Concrete may not be the most expensive flooring option available, but that doesn’t mean it won’t look high class. Concrete grinding and polishing can contribute to a modern aesthetic without the added costs generally associated with modern design.

 

Concrete is simple. When you choose a simple type of flooring, you reap the benefits of its affordability, durability, and ease of care. Whether you’re showing off your collection of sports cars or just want to install a clean and uncomplicated walkway leading up to your home, concrete has you covered.

Why Should You Consider Concrete Floor Grinding?

concrete floor grinding

Everybody appreciates quality flooring. Unfortunately, many flooring options (such as marble, granite, and tile) can be more expensive than they’re worth. When you add in the time, money, and effort that goes into caring and cleaning these options the costs can become extreme. Because of this, homeowners and business owners have turned to a convenient solution; rather than shell out thousands of dollars for flooring that needs to be delicately cared for, they’ve begun to use concrete floor grinding.

With so many tools and attachments at their disposal, concrete companies and contractors are able to utilize concrete grinding beyond its original repair purposes. Now, concrete floors can be polished until they’re as shiny as marble — only much more durable. Let’s take a look at why you should be interested in concrete floor grinding.

  • Attractive look: In addition to projecting a clean and professional appearance, polished concrete floors are excellent at reflecting light. Garages, lobbies, and even restaurants are all interested in brightening up their buildings, and concrete floor polishing is the easiest way to see a huge result.
  • Longer maintenance life: Polished floors are exceptionally easy to clean as they only require the occasional damp mopping. Because they get their shiny and reflective appearance through the grinding of the concrete beneath, the need for expensive and messy waxes or coatings is eliminated. This saves you both on the materials and the labor required to apply them. Best of all, polished concrete floors are so durable that they can resist staining from oil and chemical spills.
  • Resistant to foot traffic: Concrete can withstand, on average, 3000 psi of pressure. The combination of this fact and its low-maintenance requirements means that your business could be booming and you wouldn’t need to take the time to shut aisles or sections down to seek out repairs. At the same time, you won’t need to move anything around in order to wax and strip the floor!

There are a number of concrete services that may improve the look of your home and business (such as concrete raising and slab jacking), but polished concrete floors offer more than just a pleasing aesthetic. If you’re looking to upgrade your garage, office, or other professional space, turn to concrete floor grinding; you won’t be disappointed.

How Can I Tell If I Need Concrete Raising?

Concrete is a fickle material. Despite the fact that it can last for thousands of years and withstand pressures of up to 20,000 psi (pounds per square inch), it is also quite susceptible to damage given the right conditions. Water can be incredibly destructive if it is able to get into the concrete structure, and concrete repair and replacement can be exceedingly costly. However, in certain cases, slab jacking provides a more efficient and affordable solution.

Slab jacking is the original name for the process of concrete raising. Rather than focus on concrete crack repair or replacing the entire slab, a certain type of foam is inserted under the slabs to slowly raise them back to their original height; this can also minimize and seal any cracks that may be present, eliminating the need for a total slab replacement. If you’ve noticed the following signs in your home, you may be eligible for slab jacking.

  • Cracks: Cracks allow water to breach the barrier of concrete and get into its interior, which will cause further damage. Since the process of slab jacking is oftentimes very straightforward, it is a good option for fixing cracks and ensuring they don’t return.
  • Separation: If you notice that your walls are beginning to separate from your floors or ceiling, concrete leveling can get them back to their original positions. This also goes for porches and chimneys which may be pulling away from the home and its walls.
  • Water Pooling: When water pools up on flat surfaces such as driveways, sidewalks, and patios, it generally means that the soil beneath your slabs has become compacted. In short, the ground that your slabs were originally placed on has changed and shifted, so the concrete is no longer laying at an even angle; as a result, rainwater tends to collect at the lowest points. Since we know water is bad for concrete, rectifying this problem by raising the slab should prevent future issues from occurring.

Leaving your damaged concrete as is could end up seriously costing you in the long run, not to mention the fact that it definitely doesn’t look very good. By electing to have your concrete raised, you can save both time and money in the end.

Cracked Concrete? Slabjack Geotechnical

Have a new or old driveway, sidewalks or patio with cracks? The vast majority of concrete will crack. The cause is usually shrinkage initially, but settling takes its toll over time.

To avoid further settling and cracking, it is important to stop water penetration through the crack and into the base soils below creating voids.

While concrete mortar can make an acceptable patch if properly applied, it is not suitable for cracks that may act as an expansion joint. Mortar will simply crack and flake out over time as the concrete heats and cools with the change of seasons and even the temperature difference between day and night.

At Slabjack Geotechnical we use a commercial grade silicone concrete caulk to seal up cracks and joints on your driveway, in your garage or even around your pool. This silicone caulk will eliminate water making its way below the soil creating voids and settling.

“Should I just wait until my concrete has settled all the way?” or “I’ll just wait until it’s fully settled.” are things we hear often here at Slabjack Geotechnical.

The answer is generally “no” because as slabs settle further, damage will often result. Cracking, pulling away from the building and/or draining water to the foundation.

While no one likes to spend money on concrete repair it’s important to realize it only gets worse from today. More expensive, less athletically pleasing and greater potential for cracks.

Let Slabjack Geotechnical provide a detailed proposal about what’s going on, how we are going to fix it and what it’s going to cost. We are professional, knowledgeable and fair. Call today for your sunken and settling concrete solution.

The big question, once you have decided to do something about your settled concrete do you replace it or raise it?

This big question generally comes down to cost and if that is the only criteria then raising will be less costly in virtually every case. There are many advantages in raising rather than replacing, raising maintains the consistent look of the surrounding concrete, there is little or no damage to landscape and it will be available immediately.

What are the advantages of pouring new? It will look bright and new and the shape can be altered if desired. If there are fractures (cracks) especially several of them, we generally recommend replacement because raising the concrete will often open up the cracks further making them more noticeable.

You can count on Slabjack Geotechnical to deal honestly with you so your decision is the best choice for you. There is a time for raising and a time for replacement, we will present options so you can make the best choice for your unique situation.
