Let’s talk innovation. When we started our slab lifting and pressure grouting business we were one of the first doing polyurethane injection Slabjacking in the United States!  We made a commitment to be on the cutting edge in developing the systems we would use to pump the materials and with the material we would use to raise settled concrete.

For 2017 we have raised the bar, truly redefining our industry. Working with our builder and leaders in the spray foam industry we have developed what we see as the finest Slabjack rig in existence. Using the finest components and revolutionary design we now have the ability to bring the equivalent of two separate operations to a job all contained within one rig.

We have also, by partnering with our material supplier, developed two new polymers. A fast set, hydrophobic polymer for raising heavy structures and slabs and a very slow rise polymer for void filling and slab stabilization. Both with very low thermal requirements. This chemistry allows us to be working sooner and with less exotherm and provide far superior coverage under the slab. This means less resettlement, fewer holes, simply put a better job by design. No more using a “happy medium” material, we can now use the exact material needed for a given job.

Large Diameter Pipe Repair Methods,
We use two primary placement methods to repair large diameter pipes and culverts: spraying and injecting.

Spraying
We spray polyurethanes to rebuild joints that are poorly-seated, have dislodged, deflected or deteriorated. The materials we spray have excellent adhesion to all of the common large diameter pipe materials, such as concrete, HDPE, PVC, galvanized metal & aluminized metal. Sprayed systems are excellent for sealing joints before back grouting (see below) to contain the void filling material outside of the pipe to reduce waste.

Injecting
We inject plural component polyurethanes and single component polyurethanes outside of large diameter pipes to fill voids, fix sinkholes and provide stability. Injection is commonly used for leak-stopping as well.

Give is a call today for an onsite inspection and estimate for your large diameter pipe or culvert repair.

We recently had our floors refinished and while the end result was beautiful the company made the  buying experience frustrating. They took forever to send our estimate to us, didn’t follow up after the estimate, never answered their phone, kept us waiting without a callback and they left several rags on our lawn.

Bad experiences or less than satisfactory ones are very common with contractors for a variety of reasons but the most common are a result of one guy trying to do it all so calls are not answered or returned in a timely manner and communication suffers.

1-855-752-2522 has made many changes over the years to make buying from us as easy as possible, we want your business. Because of that we are continually refining our processes. Our aim is to exceed your expectations through the following;

1. A well trained, polite office staff to answer calls, make appointments and answer questions. We staff our office 8-5 Monday through Friday. No more feeling ignored and endlessly waiting for a return call.

Slabjack Geotechnical SPI 350H – vs – PolyLEVEL PL250 & PL400

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.

Deep injection grouting –

Pressure Grouting is the process of pumping a cement or chemical grout into soft or weak strata of soil or voids. The grout fills these voids, thus stabilizing and strengthening the soil. Pressure Grouting has many applications. One of these includes support for existing structures or where foundations have shifted.

1: The purpose of Pressure Grouting is to control the amount of grout going into the pipe. As the process is repeated at additional elevations, the soil is compacted.
2: The process begins with the pumping of grout at the lowest elevation. The pipes are withdrawn slightly and the grout is allowed to set.
3: The process is repeated at the next elevation. Upon completion, the pipe is again withdrawn slightly to the next elevation. The grout is allowed to set. Each level of grout pumping will push the soil upward.
4: The number of grout pumpings at these different elevations that are needed to compact the soil will vary. Once the soil is compacted, it causes lift. This lift then pushes the footing and wall upward.

Pressure grouting involves injecting a grout material into generally isolated pore or void space of which neither the configuration or volume are known, and is often referred to simply as grouting. The grout may be a cementitious, resinous, or solution chemical mixture. The greatest use of pressure grouting is to improve geomaterials (soil and rock). The purpose of grouting can be either to strengthen or reduce water flow through a formation. It is also used to correct faults in concrete and masonry structures. Since first used in the 19th century, grouting has been performed on the foundation of virtually every one of the world’s large dams, in order to reduce the amount of leakage through the rock, and sometimes to strengthen the foundation to support the weight of the overlying structure, be it of concrete, earth, or rock fill. Although very specialized, pressure grouting is an essential construction procedure that is practiced by specialist contractors and engineers around the world.

Slabjack Geotechnical specializes in polyurethane pressure grouting and permeation grouting. These methods are commonly used to solidify loose soil under foundations, under-seal and stabilize concrete slabs, culverts, tanks and other liquid storage facilities.

Chemical Grouting is another common form of Permeation Grouting that has gained popular acceptance to strengthen granular soils is the injection of chemical solution grouts that bond the individual grains together into tone like masses that are capable of carrying loads of the structures. The chemical solutions typically consist of a base material that is mixed with a hardening agent that causes the mix to harden at a predetermined rate, depending on the compounds used and length of set time desired for a particular application.

Chemical grouting is also commonly extensively used in leaking subterranean structures, to control water flow, and to limit ground movement during excavation and construction ( lagging operation), as well as for footing support, grouted tunnel support and for pit excavation below water.

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.
