When Is It Time To Consider Cement Raising?

cement raising

Many homes generally have concrete in some part of their structure, whether in the basement, garage, or elsewhere. In fact, it’s used so frequently in construction that concrete is used more than any other manmade material in the world. While concrete is a great choice to use in construction due to its durability and strength, it needs maintenance and repair like any other material used in your home. If you’ve got concrete in your home, here area few signs you might be in need of cement raising or concrete leveling services.

Cracks In The Structure

Whether they’re in the concrete itself or elsewhere in your house, cracks can be a sign that your concrete isn’t entirely level. These tend to show up over time as your home settles following construction, so you might not necessarily notice them right away. Check your exterior walls, around windows and door frames, and in the concrete itself if the concrete is visible. While you can use concrete crack repair services, it may be a temporary fix; you may need cement raising to really solve the problem.

Warping Floors

While floors can naturally settle and adjust over time, serious warping might be a sign that the concrete foundation underneath is cracking or otherwise uneven. A foundation that isn’t level might look perfectly fine, but on further inspection can have slight imperfections that warp your floors.

Walls Or Floors Pulling Away

Sometimes, the cracks that normally occur along window frames or in places where you can otherwise see them end up in locations that are extremely hard to notice. When this happens, they tend to worsen and cause further damage in your home. This sometimes can result in walls, floors, patios, or other structures seeming to pull away from the surrounding walls. These can create serious safety hazards when left unchecked, and you’ll want to look into cement raising to address this as soon as possible.

Damage to the concrete foundation of your home can be a serious issue that puts the overall structural integrity of your home at risk. For more information on cement raising and how it can help prevent damage in your home, contact Slabjack Geotechnical today.

Top 3 Mistakes You Could Be Making When Grinding Concrete

concrete grinding services

Concrete, of all things, is used more than any other man-made material in the world. Which means you should probably know how to take care of it. Surface preparation is a pretty competitive industry. Making sure you’re choosing the right concrete grinding services is vital if you want a quality outcome. Maybe you are experienced and feel confident in your own ability to prepare your garage floor, for example. Either way, here are three common mistakes that you want to avoid whether you’re a professional or not when you get down to the concrete grinding phase in your construction or home improvement projects.


1. Ignoring Scratches


When concrete grinding, you’ll want to keep an eye on the finish that is being produced as you go. If you are seeing faint scratches appearing, you have to remove them as soon as possible. Hoping the little nicks and scratches will go away on their own will only contribute to continued manifestation as you polish your concrete floor. If you start to see scratches after using your first resin, you should never assume that your second step in the process will “fix it”. Basically, do not leave the cracks and hope they go away because, inevitably, they won’t, and as a result, your final product will suffer.


2. Grinding Too Fast


A common mistake that operators make is running the grinder too fast. All commercial concrete grinding services should know not to do this. However, this tends to happen when the operator wants to produce results faster, so they will turn up the speed of the grinder in an effort to get more done in a shorter amount of time. However, the increased speed can overheat and glaze over your diamonds. This happens more often than not on harder concrete. This glazing over prevents them from cutting properly. Of course, finding the right speed is important but speed on its own doesn’t equal better production rates. At the end of the day, greater downward pressure equals faster grinding. A heavier machine will obviously allow for more head pressure. The opposite is true of larger machines where a double segment offers better performance due to the fact that it is grinding a larger space at one time. Concrete floor grinding is a competitive industry as well as being something of an art. Knowing that you’re choosing the best concrete grinding service, or being fully informed when doing it yourself is what is most important for a great outcome.


3. Not Inspecting Beforehand


While it sounds silly and probably seems impossible, you would be surprised how easy it is to look at a surface and assume the process. Especially if you work for professional concrete grinding services. You’ve pretty much seen it all before. However, that is not an excuse to not examine the surface you’re working with before you do anything to it. You need to inspect the floors for anything above grade and cut it off, hand grind it so it’s level, or hammer it to below grade. Address any crack repair you may need, and once you’ve eliminated any and all above grade issues, you can begin grinding it with the concrete, which results in an interesting detail which can add personality to the floor. If you DON’T inspect the floor and address the above grade parts before you start, you will almost surely damage your machine. Concrete floor grinding is probably a task that is best left to the professionals, call local concrete grinding services to get quotes and expert advice.

Sinking concrete? The options, the straight scoop. Slabjack Geotechnical


Sinking Concrete Replacement
Sinking Concrete Replacement


When you first notice your concrete settling it is a concern, when someone trips and falls it becomes a liability.

In addition to a potential lawsuit, settling concrete can create wet basements, foundation settlement and frozen puddles. Fixing theses issues starts to make financial sense when compared to lawsuits and structural problems down the road.

So, what are the options?

Do nothing – sometimes ignoring the problem is an acceptable solution. If the settlement is less than 1/2″ (1/4″ for businesses) it generally doesn’t require repair.

Replace it – you can expect to pay between $8-12 a square foot for standard broom finished concrete. This large range of price is due to several factors, both of the removal and the replacement. Was there rebar? How thick was the slab? Are there recycling facilities for the old slab? Is the new slab going to have structural reinforcement? How thick will the new slab be? How is the access to the site? And many more. Generally figure $10 for rip and replace and you won’t be far off. Of course replacement has a few drawbacks beside being the most costly option. You won’t be able to use your concrete for a week or two while the concrete is placed and then given ample time to cure. You can expect some landscape damage from the forms, concrete trucks and general worksite related issues and it can be a several day operation.

Mudjack it – A method going back to the 1930’s Mudjacking pumps a mud slurry through a hole drilled in your slab to hydraulically raise the concrete. This method is a perfectly acceptable method to raise settled concrete. The primary complaint about this method is the large holes needed, 1-2″ diameter and the large number of them since the material doesn’t flow very far from the pumping location. Price is typically half or less of replacement.

Slabjack it – With polyurethane injection. This is basically Mudjacking brought into the twenty first century. Better methods, better material, better end result. Material injected through a much smaller 5/8″ hole and far fewer of them leaves a much better appearance when completed. Material can be formulated for incredible lift for very heavy porches and structures or formulated for filling voids with little lift generated. The ability to have materials available for a wide range of uses is incredibly advantageous compared to Mudjacking. Cost is comparable to Mudjacking due to the efficiency of the method even though the material is more costly.

When should I replace and when to raise? As a general rule if your slabs are in good condition you should raise them. If your slabs have many cracks or if the top of the concrete is spalling replacement is probably your best option.

Here at Slabjack Geotechnical we have a motto- a job needs to meet three criteria, first it needs to be doable, second it needs to be profitable and third IT NEEDS TO BE IN THE CUSTOMERS BEST INTEREST. We will not do a job, no matter the profit to us, if it is not in our customers best interest to do so.

We are so confident in our service we offer a limited five year warranty.

Tools used to raise settled concrete


Modern concrete raising has gone from my messy, muddy operation to one that is relatively quick, sanitary and cost-effective. Still, many common construction tools are used in addition to state-of-the-art metering and pumping equipment. So what are the tools and what are they used for?

Hammer drill – used to drill 5/8″ holes for the injection ports as a means to get material under the slab.

Concrete saw – used to separate concrete slabs to reduce binding and slab breakage.

Ports – are plastic or metal valves placed in the concrete they allow material to be injected under the slab.

Impingement gun – injection gun that mixes two materials as it places material under the concrete.

Resin and isocyanate – materials that combine to form polyurethane foam used in Slabjacking.

Other small tools include heavy-duty jacks when needed, pry bars, tools to clean out ports, dial gauges, levels, hammers, sockets and more.

Trailer or truck mounted equipment includes generators, air compressors, pumping equipment and hoses to get to where the settled concrete is and sufficient storage for material used in the process.

Slabjack Geotechnical is your Polylevel authorized dealer


As the leading polyurethane Slabjack company in Washington state and northern Idaho we are approached by various companies to carry their product.

One of these has been Polylevel. Polylevel manufactures polyurethane for the Slabjack industry and does a pretty good job educating the public about the benefits of polyurethane over other materials such as mud or concrete slurry.

Polylevel is a brand of material just like Kleenex is a brand of facial tissue. Occasionally we are asked the question “how long does polylevel last” polyurethane used for raising concrete will last at least decades if not much longer. Accelerated aging tests done on polyurethane foam show a life expectancy of centuries so any concern about premature failures are unwarranted.

Since The 1970s polyurethane has become the preferred method of raising concrete for municipalities as well as industrial and commercial applications and of course residential benefits from these advances as well.
