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.

Raising sinking concrete slabs,

When we entered the concrete raising business in 2011 we made a commitment to be on the cutting edge of the industry in order to provide the best value to our clients.

In addition to embracing technology both in our estimating software and with our truck and trailer metering equipment we determined to use the best polymers we could find.

What determines “best”?

1.  Superior lifting ability; After testing Both Polylevel PL250 and PL400 against SPI 350H we found the following differences; The SPI 350H has a much more vigorous expansion. The quick reaction time has a huge advantage; the ability to raise very heavy structures (concrete) without needing massive amounts of material. According to the literature provided with the materials, PolyLevel PL400 and even PL250 do not lift with the aggressiveness of the SPI’s 350H

2. Superior control; With a much faster setting polymer comes much greater control over the lift. This is especially important with smaller slabs such as sidewalks or slabs leaning against a foundation. Simply put the other guys polymers don’t cut it when lifting small slabs, the material migrates to places not desired and the lift is not forceful enough to localize lift to areas desired. Even on larger slabs such as driveways the other polymers create undesirable lift.

3. SPI has formulated 350H exclusively for 1-855-752-2522 the 350H (hydrophobic) is super fast reacting at very low temperatures which provides less off gassing, less chance of charing and superior control.

I could go on, there really is no comparison between the three polymers, the polylevel foam is more like void filling foam and not really up to the task of raising concrete. They are advertised as four pound foams but comparing them side by side they appears to be about half the density of SPI’s polymer. One is structural the other literally breaks apart or crumbles under foot.

You have a choice, Slabjack Geotechnical or some other guys.

What causes concrete settlement?

18557522522
1-855-752-2522

Sinking concrete, settling concrete and slumping concrete. All terms used to try and explain what is happening when concrete is settling in soil.

Because concrete is so heavy it is prone to settling if site preparation was ignored. What is quality site preparation?

Compaction, soil barrier, drainage.

Simply put when soil is not compacted adequately it will compact over time and with added moisture.  A failure to compact will always result in settling.

A soil barrier is generally compacted gravel. Some soil types, primarily clay, will expand and then contract as it up-takes and releases water, by using a 4 to 6 inch layer of compacted gravel between the soil and the slab expansion and contraction will not be as prevalent or do as much damage to the concrete. In addition if your area is prone to clay soils using a concrete sealer will greatly reduce the propensity for clay soil’s to expand and contract.

Drainage also plays a critical role in keeping your concrete slabs stable. When homes don’t have gutters or have miss placed downspouts that concentration of water along foundations can cause porches and walks to settle. A mis-placed downspout near a sidewalk will always result in a sidewalk settling so correcting these problems is a key to eliminating settling.

If you are dealing with settling concrete you likely have one or more of the above problems. Give the concrete raising and leveling professionals a call today and we will get you taken care of.

The many causes of concrete settlement

18557522522

It’s unsightly, it’s dangerous, it’s a potential liability but it’s easy to fix.

Concrete settlement is a very common problem affecting not only residential neighborhoods but municipalities commercial enterprises and industrial facilities. What causes concrete to settle?

1. Failure to prepare the site. If soil was disturbed during construction was it re-compacted? Was there a 4-6″ layer of compacted gravel placed under the slab? These two primary issues are the cause of much of the settling commonly found in new construction.

2. The next most common cause of concrete settlement is excess water. Dealing with water runoff is generally not on a builders mind at the start of construction, it should be. Trying to figure out where you were going to put downspouts, sprinklers and  water features after sidewalks porches and driveways have been poured is poor planning and asking for concrete settlement. Having a place for your run off to drain such as french drains well away from structures or into municipal water supplies if allowed in your jurisdiction will help your concrete remain stable.

3. Another cause of concrete settlement is the breakdown of organic material in your soil. As roots, debris and other organic material breaks down is creates void space that contributes to settlement. Water migrating through the soils takes with it small amounts of soil and sand and these also contribute to the gradual settling of soil.

4. Finally ground water migration can play a role in settlement in some instances particularly if you have a high water table. We did a municipal job where groundwater migration had created a six-inch avoid behind a municipal pool. While there is little you can do about a high water table you can fill voids as quickly as possible so the supporting soils are capable of carrying the load above.

In addition to the above, the type of soil that is predominate in your area plays a role in its ability to support structures. Whether it be sand, clay or silt each has advantages and disadvantages depending on its use. Some soils don’t drain well others are prone to wash out, still others will actually expand as much as 10% with water!

If someone failed in the planning phase and you are dealing with concrete settlement give the concrete raising of leveling professionals a call today.

What can be done about voids under concrete?

Voids under concrete eventually lead to cracking and/or settling concrete. Voids are created when concrete is partially supported by base soils or through the use of anchors or rebar to foundation walls or through the use of Sonotubes. As the soil settles or is carried away by other means a gap opens up between the soil and the bottom of the concrete slab resulting in a loss of support.

Un-compacted fill dirt, erosion, burrowing rodents, decaying organic material even a loss of moisture in the soil can create voids. Once there, voids are difficult to fill. Smaller slabs such as walks can be packed with gravel or sand to fill voids but this is not practical for larger slabs such as driveways or patios. These need a method that supports but doesn’t lift the slab. Using an expansive polymer is the ideal material for void filling for several reasons such as;

Polyurethane can travel several feet in every direction to fill voids, fissures and holes. It has the ability to consolidate organic material, sand and loose rock. If properly monitored Polymer injection can provide support without excessively lifting or stressing the slab which causes fractures.

A typical void fill application for a residential job would be under a front entry. These are often “pinned” to the foundation wall with rebar. Because fill dirt is often used around the foundation and again because gutters are often not installed on new construction or downspouts are mis-placed, the fill dirt becomes saturated with water this often results in some dramatic settling. If the entry was not pinned to the foundation it will begin to settle. If it was pinned to the foundation a void will open up under the entry. Given enough time, even the entry pinned to the foundation will settle because the rebar will either bend or in time rust and break.

The question with new construction is what should I do? Settling of soil in new construction can go on as long as 10 years so the question becomes do you live with it and replace your broken up concrete at some later time or do you try and preserve it knowing that you may have someone out 2, 3 or 4 times in the next decade to shore up what should’ve been taken care of during initial construction. Immediate replacement of settled concrete or concrete with voids is not a good choice as settling is not yet complete.

Geo-polymer void filling is the best method we currently have for void filling but it cannot affect deeper layers of un-compacted fill so you are left with supporting and densifying through polymer injection.

There are other materials namely soil stabilizers that can be used to solidify deeper layers of soil however due to their cost are impractical for residential work and are primarily used in municipal or commercial applications.

Dealing with voids whether they be stable or dynamic is an important part of maintaining your concrete slabs whether they be residential, commercial, industrial or municipal.

If you see a void opening up under your concrete slabs give the concrete raising and leveling professionals a call we will get you taken care of.

What can be done about a settling foundation?

 

Slabjack Geotechnical is now a certified installer of Pier Tech helical piers and we are excited to offer this service rather than refer it to a company hundreds of miles away.

What can be done about a settling  foundation? 

If you are dealing with the nightmare of a settling foundation here is what you need to know;

-In most cases it is repairable. While not an inexpensive repair, doing nothing is usually not an option unless you plan on walking away from the home. Here’s how to proceed;

First determine that foundation settling is the issue and not simply an interior slab settling. Slabjack Geotechnical is equipped to handle either problem but one requires a building and a geological engineering report the other doesn’t.

Once the determination is made that the foundation is settling the property owner hires the engineers, they will determine the position and the number of piers to be used. The soils engineer will be on site during the repair process in case obstructions such as large boulders are met to makes recommendations and/or approve changes in the placement of piers.

Most piering jobs are completed in a few days.

The cost for the pre-work reports runs about $4-7,000 with an additional $1850-$2150 per pier depending on depth and obstructions encountered. An average foundation repair job runs in the neighborhood of $15,000, not an insignificant amount.

If you have seen the tell-tale signs of settling; cracks in brick and stucco or sheet rock separation call us today, we can help.
