Why Slabjack Geotechnical?

Having your settled concrete raised by Slabjack Geotechnical offers several advantages over our competitors.

First, we have successfully completed over a thousand jobs since our founding. From simple sidewalks to municipal pool decks to warehouse floors and void fill and stabilization. Some of our “competitors” are really insulation or basement waterproofing companies looking for a quick buck. This is not what you deserve and it isn’t the experience you should be looking for.

Second, we are large enough to handle large municipal and industrial projects. In 2017 we will have three rigs in operation each carrying thirty yards or more of polymer. While commercial work is important to us residential work is our bread and butter.

Third, our warranty now extends up to five years! Far longer than our competitors one year offering.

Finally, with experience comes knowledge. We offer as our daily use polymer a custom formulation 3.5lb hydrophobic foam. We also have the experience to offer specialty polymers to meet the needs of our customers. Need a void fill foam? We have it. Need trench break foam? We have that too. Whatever the application we have the product you need. And we will NEVER use a flimsy insulation foam.

Give us a call today we’ll get you taken care of.

Chemical grouting – Slabjack Geotechnical

Slabjack Geotechnical has been an industry leader in chemical grouting since 2011.

The injection of high density, structural polyurethane is a fairly recent phenomenon that has many applications. Some of the most common are;

Slabjacking – where high density foam is injected underneath the slab to “float” the slab back to the proper grade. Chemical injection has several advantages over the older method of mud jacking. The ability to consolidate loose and organic materials is one of them. Because it is injected as a liquid it has a tendency to follow voids and fissures in the soil, once the reaction occurs this loose material is consolidated in the polyurethane foam.

Foundation waterproofing – injectable hydrophobic or hydrophilic polyurethane foam is injected through the foundation which creates a curtain wall on the soil side of the slab sealing out moisture. If cracks in the foundation are present holes are drilled at a 45° angle through these cracks. When the chemical is injected it completely seals the crack in addition to forming a curtain wall on the soil side of the foundation.

Void filling – Due to its relative light weight, injectable polyurethane is an ideal material for void filling and vessel decommissioning. Many formulations are available from very light polymers to polymers that are fairly heavy, as much is 40 pounds a cubic foot. For typical void filling under a concrete basement floor or a warehouse floor a good choice would be a structural polyurethane in the range of 3 to 4 pounds per square foot. These typically have compressive strength in the 60 to 100 psi range. Enough to support loads up to 5 tons per square foot.

Trench breaks – typical trench breaks are made of sand bags. While effective there are several drawbacks in the use of sandbags such as; someone needs to be in the trench, which is a dangerous place to be. It can take a significant amount of time to stack up sandbags in the trench and it can be fairly costly. Today there is a better method. Polyurethane trench break foam can be applied quickly and economically without getting in the trench. In addition the same trench break foam can be sprayed over the pipe in the trench as a “rock guard” to protect the pipe.

Through the miracle of modern chemistry, better methods and materials provide more economical and longer lasting repairs to our infrastructure. Let Slabjack Geotechnical be part of your project today.

Will concrete crack when raised?

One of the questions we are asked is “will raising our concrete damage it?” With over a thousand jobs under our belt and thousands of slabs raised the answer is generally no but it is something that is hard to predict. Some of the most gentle lifting on minor settling may generate a crack whereas a huge lift may not. Why?

  1. Concrete of a thickness of less than 5″ is more prone to cracking, unfortunately this includes nearly all the poured slabs out there. Slabs 4″ thick are twice as resistant to fractures (heavy loads from above as well as lifting from below) than are 3″ slabs. The problem is slabs may be 5″ thick in one area and 2 1/2″ in another. Because we can’t know where a thin spot may be we may attempt to lift from the weakest spot on the whole slab which may generate a crack.
  2. Occasionally a slab may bind on something such as a foundation wall or another slab which can cause a crack. Most of the time slabs bound on other slabs are simply cut free of each other which eliminates the problem. Slabs bound against foundations generally can’t be cut free and if stuck cannot be raised without risking cracking.
  3. Finally, there are often cracks that are invisible to the untrained eye already in your slab. These cracks are often in areas that have settled slightly and pinched the crack together or the slab hasn’t been thoroughly cleaned and the cracks are filled with dirt or sand which conceals the fractures. Either way when raised the cracks will open up to some degree when leveled or raised.

In the end the consumer accepts the risk of a cracked slab either when hiring a replacement concrete contractor or someone to raise their concrete. By hiring the most experienced contractor whether replacement or repair you have less chance of a cracked slab when complete. For concrete raising that contractor is Slabjack Geotechnical.
