Working with a smile


Someone once said, “find something you love to do, make that your career, and you will never work a day in your life”

When you love doing something, you are driven to excellence without exterior motivation.

We all want to find fulfillment in life, our employment is a big part of that. As a restaurateur for thirty-five years, nearly twenty-five as the owner, I can relate to those who are unfulfilled or dissatisfied with their chosen profession or who have lost their zest for life.

One of the things you will notice when 1-855-752-2522 arrives on site to raise your settle concrete is we enjoy what we do. Nearly every job has something about it that makes it different from the last job we did. We rarely have a monotonous day where it’s the same old thing.

The first job of the day may be a settled porch, the next job is a driveway that has settled, then we take care of a large void under a basement floor and we finish the day by leveling a pool deck.

Each job has unique issues that need to be evaluated in order to correctly address the problems associated with the settlement and  to prevent damage to adjacent structures.

Some of the concerns are obvious such as adjacent slabs and landscaping, other issues are not as obvious such as concrete reinforced with post tension cables, where a wrong move could damage the structure, or even cause serious bodily harm, to a pool deck where the potential for damage can run into the ten thousand dollar range.

We are problem solvers. Our clients hire us to solve their various problems. From our state of the art estimating software to the modern equipment we use, to the superior polymers we select to raise and level your concrete, the entire structure of our company is directed to one objective; leveling your concrete with surgical precision, through a process that is affordable, fast, safe and permanent.

If you have sunken, settled, sluffing, sinking, tipping, tilting, falling or dropping concrete, call the concrete raising and leveling professionals – 1-855-752-2522

Property Management Firms hire Slabjack Geotechnical


Property Managers deal with a multitude of challenges, from rent collection, to employment issues,  to facility maintenance and ultimately satisfying the property owner(s) through managing a property which offers a good return on investment.

Each property owner has a different philosophy on how a property should be operated and maintained.

Some want to improve and then continually maintain their properties to the highest standard in order to maximize the rents that can be charged. Another owners philosophy may be to target the low-income renter and are therefore not as concerned about providing the latest amenities, a pool for example, or as high of standard of maintenance.   Others target federally subsidized renters which demands an additional layer of administrative oversight.  All understand that a simple 1/2″ sidewalk trip hazard could cost them tens of thousands of dollars in potential liability.

Because of this, each owner or ownership, has different requirements of the property management firm they employ.

One of the things 1-855-752-2522 provides property management firms is an understanding of this reality along with the equipment and materials to address the reality of different budgets for effective solutions to all types of concrete maintenance needs.

As a business owner myself for over twenty-five years I know that what works for one owner and facility may not work for another owner and facility just down the street.

Whether you are managing a single four-plex, a three hundred unit townhouse complex or a condominium association, we are capable of handling all your concrete raising and leveling needs.

A.D.A. Compliance for federally subsidized properties, trip remediation for the reduction of liability, concrete grinding, pool deck leveling, structural concrete crack repair and more.

We have worked for property management firms from Spokane to Walla Walla, from Wenatchee to Sunnyside, from Ellensburg to Yakima to the Tri-Cities and Northern Idaho and more.

Contact us today for a no cost, no pressure evaluation of your facility to see if we may be of assistance in the elimination of liability, A.D.A. Compliance, and improvements to the aesthetics and integrity of your facility.

Getting a written estimate by phone?


As our concrete leveling business at 1-855-752-2522 has grown, a big concern has been to maintain the same, or better level of service to our customers. We strive to be the easiest concrete raising company in the industry to do business with but with growth, this makes getting to estimates in a timely manner especially challenging, particularly in the spring when we are at our busiest.

In order to meet our customers expectations of timely estimating we have added a phone estimate option. 1-855-752-2522 uses the latest generation estimating software which uses simple dimensions to generate the estimate. By using a mathematical formula we can be accurate and consistent with all of our clients.

The way it works is this; a potential client calls us with the dimensions of the slab needing to be lifted (length and width) and how far it has settled, if they can email or text a picture of the slab in addition, that’s even better. With the software we have, we simply enter those figures into the program which then generates an estimate for the job.

We have found that as long as the dimensions provide by the client are correct, the estimate is nearly always accurate. When the estimate is complete we email or print a copy and send it to the customer for approval. The turn around on a phone estimate can be as little as ten minutes.

When we come on site to do the work, we will make an inspection of the slab to be lifted to make sure the estimate is accurate and if so, proceed with the job. If we find a problem with the estimate or the slab is not a good candidate for raising we will inform the client of the reasons and the options they have.

Our goal at Slabjack Geotechnical is to have the estimate done within a week of the initial request. By having the option of a phone estimate we can meet this goal and better serve our large geographic area.

For many people a phone estimate is just what they want. Phone estimates give timely, accurate estimates that allow for an immediate approval if they so desire, and a quicker turn around on the job being completed.

If you would like a phone estimate to have your settle concrete slabs back to level, jot down the dimensions of your settled concrete along with how far it has settled and give us a call. We’ll have you taken care of in no time.

Traditional Mudjacking -vs- Slabjack Geotechnicals Polymer injection


Geo-Polymer injection concrete leveling is the Great Leap Forward in the Slabjackers arsenal. For years those with settled concrete had few options; live with it, replace it or deal with the drawbacks of mudjacking; the huge holes, the mess, the shoddy appearance after the job was done and more.

Today, 1-855-752-2522 uses state of the art Polymer injection to raise your settled concrete.

While producing virtually the same end result, raised concrete, Polymer injection overcomes the drawbacks of mudjacking:

– Hole size; 1″ to 2″ verses 5/8″. Much easier to conceal, doesn’t weaken the slab.
– Mess; mudjacking uses…well…mud. Requiring the hosing off of the work site after the job. People complain about the mess left after Mudjacking is done as the equipment is often hosed off at the job site.
– Appearance; concealing large holes is just more difficult. Most Mudjackers use a 1.5″ hole compared to the 5/8″ hole we drill. Mudjackings hole is FIVE times as large! On top of the smaller hole we have two different mortars, light and dark, and five different colors to match your unique concrete, whether it be a plain broom finish, exposed aggregate or stamped and stained.

Give us a call, we provide no cost, no pressure estimates.

The concrete raising process


For those who are unfamiliar with the concrete raising process, it’s a fascinating thing to watch concrete rise out of the ground, we never tire of it.

When we come to your site we are bringing $100,000 worth of concrete leveling equipment, tools and material, along with the experience of having raised thousands of settled concrete slabs.

As we arrive on the job site, the first thing we do is start the equipment that heats the Geo-Polymer to 130 degrees. While the material warms, we determine the best location for the injection valves and drill 5/8″ holes at those locations. For very narrow slabs settled on their side, jacks may be used to position the slab prior to the Slabjack process.

The number of holes we drill is determined by the size of slab and direction of the settling. Steel valves with a plastic collar are screwed into the concrete and the injection gun is attached to the valve with a special clamp.

Once the materials are heated, which takes fifteen to thirty minutes, the lift can begin.  Prior to the initial injection, the gauge that measures material usage is “zeroed” or reset.  The material is then injected at pressures as high as 1300psi but it is the expansion of the Polymer under the concrete that creates lift, not the injection pressure.

To monitor the lift, extremely sensitive gauges are used that measure 1000ths of an inch. This is important so we don’t over lift the slab. Those gauges are also critical when void filling where lift is not desired. We can see within a thousandth of an inch when the void is full, much sooner than we could with the naked eye.   Over filling void space creates unwanted lift and potentially cracks the slab.

When the proper elevation is reached, the support holes are injected to ensure the stability of the slab.  One of the real benefits of Polymer injection over Mudjacking , is the small holes and a material that flows much better than a mud slurry which often pyramids under the concrete, so requires many more holes than does Polymer injection.

Prior to turning off the equipment, the poundage used for the lift is recorded and compared against the estimate.

After putting away the hose and other tools used during the process, the holes are patched with quick-setting mortar, tinted and colored, if necessary, to match your concrete and the job site is swept clean.

When we leave, your are free to use your concrete. We use quick set mortar that is hard after about half an hour, but you will want to avoid direct water pressure for a day.

When you hire 1-855-752-2522 to raise your settled concrete, you can rely on four things; Superior Technology, Superior Polymers, Superior Training, Superior Results.

Concrete Crack Repair Basics


I just had a new driveway/patio/porch poured and it already has a crack!

The vast majority of concrete will crack. The cause is usually shrinkage initially, but settling takes its toll over time.

Shrinkage cracks are typically small with virtually no discernible opening. These type of surface cracks can generally be ignored. Once they open up or settling causes a height differential, it is time to act.

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

Fortunately, there are many over the counter products on the market today to patch or seal cracks in concrete, from simple flexible caulking, to two part Epoxies and Polyurethane systems.

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.

For inexpensive crack repairs, non-sag and self-leveling Polyurethane caulk is acceptable for sealing out water, some even come in a variety of colors to blend with stained concrete. The least expensive Polyurethanes caulks, available in grey, can be found at Home Depot, Lowes and Ace hardware stores. For colored concrete, Sonolastic NP1 comes in a variety of colors to closely match any  concrete color you might have.

For more of a structural repair, the two part Epoxies and Polyurethane systems are excellent choices but are much more expensive, and some are not available without a contractors license. One of the advantages of these type of repairs is they can often be blended to more closely match the surrounding concrete, somewhat like a mortar repair but with much better durability.

Why wait? Have your concrete raised!


Concrete raising and leveling is quick, non destructive, preserves the look of existing concrete and is much less costly than replacement. So why wait?

Of those who call 1-855-752-2522 for an estimate most have us make the repair, but of the jobs we do, we see ten others in the same neighborhood that never call, why?

Many people have never heard about Slabjacking. This process has been in existence since the nineteen thirties where they pumped a mud slurry under the concrete to hydraulically lift the slab. While most in the industry still use this method, 1-855-752-2522 uses superior equipment, materials and methods. Today’s Slabjacking is so superior to mudjacking that you may not even be able to tell we were there with the exception of your concrete being level.

People may think their landscaping may be destroyed. With superior equipment and materials comes better methods. Unlike mudjackings large mixing trucks and heavy hoppers, 1-855-752-2522 simply brings a self-contained trailer to your site and pulls a hose from the trailer to inject material under the concrete.

People may think the concrete will look bad if holes are drilled in their concrete. For those who have had mudjacking done and were not happy with the 2″ holes and poorly matching material used for patching those huge holes, 1-855-752-2522 has great news, we drill far fewer holes and the holes we drill are 5/8″ about the size of a penny. We also have two different tints and match color for those with colored concrete. We also match, almost perfectly, exposed aggregate.

Finally, people think they can’t afford it. While everyone has to determine for themselves what they can afford, Slabjacking is typically 1/4 to 1/2 the cost of replacement. We also offer free, no pressure estimates and let you decide if it is right for you.

1-855-752-2522 wants to be the easiest company to do business with. We accept Visa, Master Card, Checks and do short-term financing in-house.

Considering the purchase of a home with settled concrete?


One of the things we do is raise settled concrete for folks preparing to sell their home.

Why homeowners wait to raise their settled concrete will be the next topic I discuss in this blog.

If you are in the market for a new home, one of the deficiencies you may come across is sunken or settled concrete. Having this concrete raised prior to your purchase should be something you demand as a condition of purchasing the property, when you have leverage.

In most cases raising settled concrete is a quick, fairly inexpensive job. There are some areas that are more technical and challenging, such as around pool decks or large entries with columns or superstructures built on top of concrete slabs, but for most walks and patios it’s a two or three hour job

The last thing you want to find out after the fact, is that the pool deck is beyond repair and needs to be replaced at a cost of $5-$10,000 so ask the listing agent to call the concrete raising and leveling professionals 1-855-752-2522, and we will raise the settled concrete BEFORE you buy your new home.

Expansive soils equals settled concrete

Slabjack Geotechnical

Do you have slabs that seem to rise and fall with the seasons?  Then you are likely dealing with expansive soils, in our area, generally clay. Much of the United States has expansive clays to a greater or lesser degree.

In a typical year in the United States, expansive soils cause a greater financial loss than earthquakes, floods, hurricanes and tornadoes combined.

Clay in and of itself isn’t the problem, the problem is the change in moisture content.  If the moisture content stays the same no swelling or shrinkage will happen.  In Washington State, and in particular Easter Washington, we have four seasons where we can expect cold wet winters followed by warm dry summers.

When we combine expansive soils and wet winters followed by dry, hot summers, heaving and settling are to be expected.

I personally have one section of my driveway that magically rises from the ground about 3/4″ each spring and as the ground dries, settles back down.  Not surprisingly it is on bare soil with no gravel bed.

Some people call to tell us their slabs used to rise and fall, but now they are staying up, why?  First let’s try to eliminate the issue.  In my case the section that rises and falls is the lowest of six driveway panels, water seeps between the expansion joint when it rains or snow melts, (I really should seal that joint) saturating the underling soils causing expansion.  As the summer heat comes on, the soils dry allowing the slab to settle.  To reduce heaving and settling, seal all expansion joints on your concrete. A good, inexpensive product is Sika brand (Home Depot) or Quickrete brand (Lowes) polyurethane caulking.

If slabs are not resettling as they used to, then two issues may be in play;  first, debris washes under slabs which cause the slab to remain high, this is very common. Second, you may be over watering your soil keeping it saturated and swollen.

When expansive soils shrink, fissures can open up which allow water to run off and carry away soils, causing settled concrete slabs along with cracked and damaged driveways, porches and patios.

The key to building on these type of soils is to insulate concrete as much as possible from the soils. Gravel should be used as a foundation in the construction of driveways and walks.  Caulking along seams and  joints and along foundation walls minimizes water penetration under slabs and, especially important to basements, making sure concrete slabs are not settling toward foundation walls draining water along the basement walls.

If you have sunken and settled concrete call the concrete raising and leveling professionals 1-855-752-2522, for a no cost, no pressure estimate to have your damaged concrete raised back to proper grade, using state of the art Geo-Polymer injection technology.
