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.

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.

The problem with pools.


Pools, what a great way to spend a lazy summer day. Kids and Grand Kids enjoying the water, friends over for a pool party as you BBQ Ribs or Burgers, or just a relaxing evening enjoying the crystal clear water as the sun goes down. Having your own pool is a dream come true for many families, one that can build unity and be a gathering spot for family and friends for years, even generations to come.

Then there is the cost and hassle of chemicals and maintenance, all of which pales compared to the nightmare of settling pool decks. At 1-855-752-2522 we’ve about seen it all. Here are some things to know about settled pool slabs;

How we approach settled concrete slabs around pools varies with the type of pool, be it Gunite, Fiberglass or Vinyl.

Let’s first discuss Concrete or Gunite Pools;  these pools have the most robust construction of the three and are considered the safest to work on, having been constructed of a special concrete reinforced with rebar.

Typical deck construction on Gunite pools is to lay the deck over the top of the vertical wall of the pool, which is then caulked with waterproof pool caulking. This method leaves a very clean look with no bullnose tile to be found, though for aesthetics they can be used.

Settling occurs two ways. First, over time the caulking seal fails, allowing water penetration which leads to the compaction of fill dirt under the deck and along the walls of the pool, which over time, caves the soil in toward the pool and gradually leads to “pivoting” of the concrete deck.

The second area is on the outer side of the deck, where the deck meets grass. This settles slightly as water saturates the soils along the edge of the deck and grass junction. As this settles ever so slightly the slab pivots, opening up the caulk line allowing water to again, penetrate and further saturate and compact soils.

We have two good views and a video of a pool deck “pivoting” at in the before and after pictures section as well as in the video section.

The diagnosis – if we were to completely lift the slab off the side of the pool you would find large voids along the pool, with the largest at the edge of the pool, even though the settling appears to be on the opposite, or grass side of the deck.

The cure – while the safest of the three, due to its robust construction, Slabjacking can exert tremendous pressures, thousands of pounds per square foot in some circumstances, not something we wish to have against the side of a pool. 1-855-752-2522 uses a hydrophobic Polymer (waterproof) that is injected and allowed to flow into the voids along the pool, consolidating loose soils and filling voids. This Polymer is very light, only four pounds per cubic foot but extremely dense so it is much safer than pumping a slurry which weighs between 100-140lbs per cubic foot against your pool. After these voids are filled any settling is taken care of on the opposite side of the slab.

Fiberglass and Vinyl pools are much less robust and as such, are approached much differently than concrete/Gunite pools. Due to the flexible nature of Fiberglass, and especially Vinyl pools, we do not attempt to fill voids along the vertical walls, doing so could bulge the pool walls and there would be nothing we could do about it after the fact. We will raise decks settled toward these pools only after extensive testing and then only with a disclaimer in the contract. Decks settled away from these pools are generally safe to raise and pose minimal risk of damage to the pool itself.

When it comes time to raise your pool deck call the concrete raising and leveling professionals 1-855-752-2522. Whether a Residential, Commercial or a Municipal pool, Slabjack Geotechnical is the right call – superior Equipment, superior Polymers, superior training, produces superior results.

Tips for builders


Home builders, do you want to avoid dissatisfied clients with regard to sunken and settled concrete? Here’s how.

Follow industry guidelines for compaction. Yes I know these are not enforced but they are a sure way to nearly eliminate all settling. It costs to do compaction according to industry standards, it costs to take the tests and document the results, however by doing this you insure the end user, the homeowner a superior product. Advertise it, let potential clients know you provide a service that virtually no one else does. Quality sells.

Do not pour concrete on unprepared top soil. All concrete should be poured over at least four inches of compacted gravel. Concrete is porous, water moves through it fairly quickly, if all it has is soil to drain into, and that soil is clay (which is expansive) the slabs will heave with the moisture and crack. Compacted gravel allows water to drain safely away.

Don’t saw cut control joints, form them into the concrete. We have found virtually all control joints which are saw cut, are not of sufficient depth to work as intended. Conversely, we have found formed control joints nearly always perform as intended.

Use rebar. In most cases concrete will crack, whether due to shrinkage, thermal (expansive soils) or dynamic loads. Rebar allows concrete to crack without causing the slab to dislocate vertically or horizontally. A cracked slab with rebar can always be Slabjacked, without rebar it is much trickier to align the slabs perfectly.

Pin horizontal slabs to vertical walls with 5/8″ rebar when possible. Driveways to garage foundations. Patios to foundation walls. Garage floors to foundation walls. Yes it is more work, but when coupled with proper compaction, provides an added element of stability for the slabs.

Provide a foundation or at a minimum, Sonotubes, under all entries which are more than a simple 4″ to 6″slab. Blueprints rarely specify the type of entry, rather this is dictated by slop of the land and personal preference, as a result the architect does not draw a foundation for this section of the house. We recommend all concrete entries have a foundation or at a minimum, Sonotubes of ample size, tied into the entry with rebar to support the weight anticipated.

All step up entries, all entries with columns, or those that act as support for any superstructure need to be extremely stable, in addition to the above we also recommend pinning with 5/8″ rebar every three feet to the foundation wall.

Backfill all slabs which will be in excess of 8″. A small entry of six by seven with two steps, if poured without backfill will weigh in excess of five tons and requires over three cubic yards of concrete. Poorly compacted fill simply cannot support this load and will settle until sufficient bearing loads are reached. This may be one inch, it may be a foot.

Don’t make the addition of gutters and down spouts an option, install them on every house you build. Plan for the elimination of water away from foundations walls at least five feet and slope soils well away from foundations, this will not only keep any basements dry but will greatly reduce settling concrete slabs.

Giving back.


One of the best things you can do for yourself is to do something for someone else. There is something about serving others that makes us happier with life.

Welcome a new neighbor with a plate of cookies, donate some time at a homeless shelter, visit an elderly neighbor, befriend a lonely child. “In as much as ye have done it unto one of the least of these my brethren ye have done it unto me” whether you are Christian or not, living the golden rule is a key to a well lived life.

I’m sure a lot of you had or have Parents like I did. Growing up in the 1920’s and ’30’s like they did, service was expected of everyone in the community, and kids were taught at a early age to not only work, but to be good neighbors too.

I don’t think my Father could have heard a better compliment of one of his seven children than “your kids know how to work” I think that said as much about him as us. Early in his life my Dad owned a full service Dairy. He milked the herd, pasteurized the milk and then delivered It.  Because of the nature of such a profession he worked for seven years straight, without a single day off!

My folks grew up during the depression, as a child I was expected to “finish my plate” and “turn off the lights” my older brother jokes that Dad may have invented copper wire because he could stretch a penny so far. My Mom wasn’t going to be outdone, she bought the “special today” meat, and once tried to pass off sour milk, concealed, as it was, as chocolate. (Failed miserably)  Overall though, I had great parents and have been richly blessed by the lessons and values they instilled in me.

At 1-855-752-2522 concrete raising, we love the communities in which we work. We live here, we shop here and we want to give back to those who have made us a success.

For the 2014 year we are donating two free concrete lifting jobs.

The first is a drawing open to anyone who attends one of the home shows we are in this year, for dates go to (go to events to find when the show dates are for your area) Spokane, Tri-Cities, Wenatchee and Yakima. (Value up to $500) Drawing to be held 4/15/2014

The second is open to Non-profit organizations and Veterans. (Value up to $750) if you know a Veteran, or you yourself are one and need your concrete leveled, please fill our the bid request form on our web site noting you are a Veteran, and forward this blog to other Vets you know. This drawing will be held 7/30/2014

Commit to doing a random act of kindness this week, then get out of your comfort zone and volunteer, you will not regret it.
