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!

To Raise or Replace


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.

Can water be a cause to my settling issues?- Slabjack Geotechnical


Poor compaction coupled with excess water causes virtually all the settled concrete we see.

We got a call from a homeowner that their fifty year old home was experiencing some settling on a porch and some attached brickwork. I asked, “the house is fifty years old and the settling just happened?” She replied yes but they had recently installed gutters and downspouts and she suspected that might be the cause.

A site visit showed that she was correct, the downspouts was dumping runoff right at the point of settling. An estimate was provided and the work was completed using Geo-polymer Slabjacking as well as sub grade concrete and steel bracing for the decorative brickwork.

This is so common.  Here’s how to prevent the problem;

New construction – install gutters and downspouts before concrete is poured, insuring water is directed well away from porches, walks, driveways and foundations. Where municipal codes allow, tie into storm drains, if not, dig French drains or use other methods to avoid saturating soils near concrete slabs.  Other concerns are landscape plantings too near foundations and slabs, tree roots, ponds and sprinkler systems.

Existing homes – design the gutter system with the intent to have water going somewhere other than near concrete slabs and structures. This may necessitate tunneling under walks with a drain pipe directing water well away from the home. If this is impossible a French drain can be dug, rain barrels used  or use the retracting downspout extensions that unroll to direct water away from structures when there is run off.

Take the time before settling occurs to correct deficiencies and you will avoid the problems associated with sinking concrete.

Slabjack warranties generally require the correction of the problem that created the original settling. In the vast majority of cases it means making corrections to your drainage system, eliminating plantings that require substantial water, reducing sprinklers or using drip lines instead.

Slabjack Geotechnical is a great resource when it comes to diagnosing the cause of settling and recommending corrective measures to prevent further settling. Call today,

Concrete Trips- Slabjack Geotechnical


According to the National Floor Safety Institute the average medical cost from a slip/trip fall is $22,800! The potential legal costs and jury awards are several times that amount. Rather than ignore the “little trip” have it fixed by Slabjack Geotechnical.

Whether it be a walk from your driveway, a trip on your driveway or a sidewalk by the street, you, the homeowner, not the city, are responsible for maintaining the walk and keeping it free from snow, debris and known hazards such as trips due to settled concrete.

A quick and unobtrusive process, Slabjacking raises settled concrete through the use of an expanding polymer grout. Most jobs are done in a couple of hours and the walk is available for immediate use. No waiting for forms, concrete and curing. No destruction of lawns or plant, just a quick drill, inject and patch.

Having Drainage Issues?-Slabjack Geotechnical


A big part of eliminating settled concrete is to plan your drainage system. Addressing runoff will pay dividends for years to come not only in reduced settling but in keeping your basement dry and foundation stable.

Some communities do not allow gutters to be directed into storm drains or into the municipal sewer system and therefore must be handled by French drains and simple sloping of top soils to direct runoff well away from structures.

Time spent planning where water will go and the amount anticipated is something your builder should do, if not have a conversation about getting water well away from any concrete walks, drives, porches, etc.

Time and planning spent here can save a significant amount of money and headache down the road.

If that didn’t happen and you are dealing with settled concrete give us a call, we can help.

Concrete Leveling in Washington


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

As we arrive on the job site, the first thing we do is start the equipment and 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 lifting process.

To monitor the lift we use 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.

Once the lifting and/or void filling is complete 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 Slabjack Geotechnical to raise your settled concrete, you can rely on four things; Superior Technology, Superior Polymers, Superior Training, Superior Results.

Concrete crack repair and caulking – SlabJack Geotechnical


Cracks in concrete are a common complaint, unfortunately concrete is guaranteed to do two things; get hard and crack.

I read a statement that made me chuckle, it said that every load of concrete comes with four cracks – where they happen depends on the concrete contractor.

There is a lot of truth in that statement. Without the proper placement and depth of control joints, cracks can happen just about anywhere on the concrete slab. In addition, failure to prepare the surface and pour concrete on compacted gravel along with reinforcement such as rebar or welded wire mesh and the odds of slab fractures and displacement go up dramatically.

When concrete does fracture what should you do? The answer has to do with what you intend on doing with the concrete afterwards. If it is a crack in a sidewalk or driveway the best solution is usually to caulk it with a good quality concrete caulk then attempt to blend in with the color with the addition of sand it that closely matches your concrete whether it be broom finished or exposed aggregate.

If your intent is to do a concrete coating or paint afterwards a more rigid repair is called for. Companies like Roadware or Emecole manufacture rigid polyurethane or epoxy crack repair material that do a relatively good job of at least closing the crack which enables the coating or paint to perform much better.

For caulking if you’re comfortable with a non-sag caulk and the tools needed to apply it we prefer high-tech silicone concrete caulking from Silicone Depot. The beauty of silicone caulk is they do not weather like polyurethanes and have roughly 4 times the flexibility of polyurethanes so they are better suited for exterior applications. Another benefit of silicone is it doesn’t have a tendency to bubble like polyurethane caulks do. A quality caulk should last many years if you can avoid pressuring washing at a close range.

While it is not a fun job caulking cracks and joints will pay many dividends. Will reduce erosion and thus more slab cracking will reduce concrete settling and it will stop weed growth and burrowing insects. All in all a lot of benefit from not a lot of money.

What do you do it yourself or hire a local company it’s money well spent.
