What Is Pressure Grouting?

pressure grouting contractor

Concrete is the most commonly used man-made building material in the world today. Among the qualities that keep it so popular are its strength, fire resistance, insulative properties relative to energy and sound, and its tremendous durability and impact resistance. The earth it’s built on, however, doesn’t share all of these merits. Not all ground is created equal, and much of it lacks the stability for building on. But built on it is. And this can often result in significant structural and foundation issues in time. Pressure grouting by a qualified and experienced pressure grouting contractor is one common solution for foundation problems in inaccessible areas.

What is Pressure Grouting?

Pressure grouting, sometimes called “jet grouting,” is a process in which a pressure grouting contractor injects grout compound into a subterranean void, weakness, or fault that would otherwise require extensive and costly excavation and construction to reach. A number of compounds and mixtures are used for pressure grouting, including cement, chemicals, resins, and combinations of these.

Common Causes of Foundation Problems

There are a broad range of causes for failing foundations. Some of the most common are:


Substrata that isn’t ideal for building or that isn’t properly prepared for building can wear, sink, and grow unstable from normal use and pressure and time. Ground that may otherwise sustain building and wear for long periods of time can be compromised more quickly when the structures that straddle it contain building or engineering errors, which are common even with the best credentialed and most experienced builders. A qualified pressure grouting contractor will be able to assess the causes and potential solutions.

Water penetrates substrata in a number of ways and can cause it to deteriorate. This can be the result of erosion, floods or excessive rain, excessive water accumulation, or improper drainage. Substrata deterioration can be more common and more severe in certain regions of the U.S. If you live in a rainy region, or close to significant bodies of water, have your structures assessed by a pressure grouting contractor regularly.

Substrata Constitution

Not all earth is inherently suitable for building. And, as it is with the weather, some regions are more vulnerable to faulty substrata than others. A pressure grouting contractor in your area will know about potential threats to your foundation.

How Pressure Grouting Solves Foundation Problems

Regardless of the catalyst for foundation problems, it is vital that they be corrected. And one of the least invasive and most cost-effective ways of correcting foundation issues that result from ground faults is pressure grouting by an experienced pressure grouting contractor. Pressure grouting and soil cement stabilization fills, reinforces, and stabilizes faults, sinkholes, and can fill concrete voids under the soil and foundation without jeopardizing the structure or resorting to invasive and costly excavating.

Pressure grouting is a common and versatile solution for dangerous foundation problems that can threaten your home but is still a specialized process that requires the training and equipment of a qualified pressure grouting contractor. Contact a pressure grouting contractor today to learn more.

What Are the Benefits of Concrete Floor Grinding?

concrete floor grinding

Whether it’s for a home or a business, everybody wants attractive and durable flooring that is low maintenance and cost-effective to install and keep up. But if your concrete floor is damaged, you might be tempted to cover it up with something else. Don’t! Keep reading to learn why you should invest in concrete floor grinding and restoration.

What is Concrete Floor Grinding?

Originally a method used by concrete service contractors in the repair of concrete, marble, and granite floors, concrete floor grinding is a process of grinding and polishing concrete floors until they have a sheen similar to that of a finished marble, hardwood, tile, or granite floor, for a fraction of the cost and a great deal less fuss. Concrete grinding service professionals employ a number of different tools and processes to produce concrete floors with varied and enticing finishes. Each of these could be a great fit for rooms and of all kinds, from garages to rec rooms to bathrooms, living rooms, and kitchens. The high durability of concrete makes it a popular alternative to other flooring options.

It’s Low Maintenance

Easy to clean and requiring minimal maintenance, floors finished with concrete grinding possess a natural shine that doesn’t depend on the regular application and reapplication of awkward waxes, polyurethane or other finishing coats. And they resist marking or staining by nearly any substance, even paints, oils, and many chemicals. They require periodic and easy cleaning with a dust mop, and intermittent deeper cleaning with standard floor mops — that’s it.

It’s Durable

Floors finished by concrete floor grinding are nearly impossible to damage and last a great deal longer than hardwoods, laminates, tile, linoleum, and other flooring choices. And the minimal cleaning they require extends their life as well, as they need almost no scrubbing, no contact with harsh detergents, and very little wet cleaning of any kind.

It’s Beautiful!

Concrete floors that have been finished by concrete grinding are not only polished and unique, they also project a professional, sanitary, and clean image. Their high sheen enhances a room’s natural light, and can brighten even dim or dark rooms that draw less natural light. The natural Earth tone of a finished concrete floor is versatile enough for almost any decor or color theme, and few decor choices bring the outside in as well as floors finished by concrete floor grinding.

FAQ About Concrete Raising

concrete services

Concrete or cement raising (also known as slab jacking) offers a cost-effective solution to damaged concrete surfaces. Although the practice has been around for nearly 100 years, many people don’t know very much about these concrete services. Let’s take a look at some of the most frequently asked questions regarding concrete raising.

How much does concrete raising cost?


Concrete raising is usually about half the cost of concrete replacement. At the end of the day, however, the cost of the process is a direct reflection of much leveling material the project will require; generally speaking, slab jacking can cost between two and five dollars per square foot. You’ll need to contact your local concrete company to find out their specific rates, but either way, you’ll be saving money by opting for raising over replacement.

What kind of material is used to raise concrete?


Polyurethane foam (in liquid form) is injected under the damaged concrete. It solidifies into a rigid foam as it raises the slab back into position; this material does not lose its density or shrink in any way, so you won’t need to worry about future issues. As a more advanced form of the traditional mudjacking material, less holes are required to use it, and the holes are smaller so the repair is virtually invisible.

How are the holes sealed?


After the concrete has been raised via mudjacking, a foam plug is inserted into the hole and then patched over with cement. The foam plugs act as shock absorbers when slabs are affected by seasonal frost. For concrete raising that uses polyurethane foam, these plugs are not required because the foam performs both functions. Although the final product will be ready for use immediately, it’s recommended to allow the patch material to set first.

What concrete can be raised?


As one of the most beneficial concrete services, any cracked concrete slabs are able to take advantage of concrete raising. However, there is a limit; slabs that are horribly cracked may be too damaged to lift. Your local concrete contractor will be able to let you know the status of your repair and whether or now it can be performed.

If you’ve got a concrete driveway or garage floor, cracks are bound to emerge. Eliminate them immediately with slab jacking concrete services.

How To Repair and Care for Your Concrete Floors

Concrete’s performance and affordable price point have led it to replace traditional flooring materials such as marble, granite, tile, and linoleum over the years.

The types of concrete flooring available for your home

There are three types of stylish concrete flooring available for your home:

  • Plain concrete
  • Stained concrete
  • Polished concrete

Concrete flooring is as functional as it is stunning

What are some other upsides of polished concrete flooring?

Concrete is incredibly durable. In fact, its average strength is about 3000 psi, meaning it can withstand more than a ton of pressure!

Pet stratches and even the pointiest of high heels are no match for this tough substance.

But enough about the perks. If you already have concrete floors installed, or are seriously thinking about it, continue reading to learn how to care for and repair them.


Concrete floors a low maintenance, so they’re perfect for the minimalistic homeowner. The first thing you want to do is opt for a sealer to help prolong the life of your concrete floor. When choosing a sealer keep in mind that there are many options to chose from. A water based sealer is non-toxic and perfect if you live with pets or small children.

Other sealers that each offer their own can add a beautiful shine to your floors include:

  • Acrylics — come in water-based formulas and a variety of different finishes
  • Epoxies
  • Polyurthanes
  • Siliconates — offer a matte finish

When it comes to cleaning your floors, the process is simple. Use a microfiber cloth when mopping and make sure to use a ph-neutral based cleaner. Avoid chemicals such as bleach and ammonia as they are too harsh and can damage your floors.

The issues and what to look out for

Though concrete is sturdy, air or water can cause small holes to appear on the surface. These are called voids or bugholes.

So now you’re probably wondering how you can fill concrete voids. They can be easily smoothed out and you only need a few things and some extra time on your hands to do the job.

How to fill concrete voids

Filling voids in concrete doesn’t have to be a difficult process.

  1. First, you’ll need to drill four holes around the indented area. The holes should be about one inch in diameter.
  2. Once you have done this, connect a slabjacking pump and hose, made to fill reparative material under the concrete slab.
  3. Next, combine one part cement to one part fly ash with two parts clean sand and mix with an expander additive. Add water until the mixture has a grout-like consistency.
  4. Set the slabjacking pup to 10psi after feeding the mixture into the machine and pump the material through the hose.
  5. Fill the void evenly and allow it to dry.

Concrete crack repair follows a slightly similar process if you’re looking to fix an unsightly crack instead. But when dealing with holes, that’s how you fill concrete voids a few steps. If you’re still struggling, don’t be afraid to call in a professional.

The takeaway

Concrete floors can compliment your home beautifully. Especially if you know how to care for them and understand how to fill concrete voids. There’s no reason they shouldn’t last you for years to come.

Caulking and why it is necessary


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.
