City Creek Center is an up-scale shopping mall in downtown Salt Lake City. While under construction a five-foot-wide trench, located between two underground parking garages, was back-filled with pea gravel, and then a sidewalk was built on top of it. About ten years later the gravel began to settle enough to cause underground power lines to stretch and finally tear, knocking the power out for many of the local businesses. Engineers determined that the trench could be stabilized with the installation of polyurethane grout at depths of 30 feet below the surface. PolyFoam Solutions, a local geotechnical services contractor, was called in to perform the work. 

Powerful Polymer

AP Fill 700 is a single component, water-activated, hydrophobic, low viscosity, closed-cell polyurethane injection resin. This polyurethane material was selected because it is ideal for both permeating soil and filling voids. It also provides excellent strength and stability.

Painless Procedure

An Alchemy-Spetec technical consultant worked closely with the geotech contractor to develop the injection plan, detailing exactly where each of the injection points would be located. The plan was then communicated to the engineer and approval was given to move forward with the project. The geotech crew installed 10 injection tubes 30 feet deep into the soil. They then pumped approximately 1 gallon per vertical foot of AP Fill 700, as they pulled the tubes up 1 foot at a time. The injection points were spaced about 36” apart.

Rapid Result

After only two days the site work was completed, and the general contractor was able to move forward with filling the trench and repairing the sidewalk.

One of the many joys of my job is going to all corners of North America and participating in unique projects. While I am a seasoned traveler, cement is not. Cement grout often requires heavy equipment. Shipping cement grout and related equipment can be expensive. While often not a concern for most projects, it is a driving factor for remote locations.

I have been involved with numerous projects in which cement grout would be an acceptable repair and more cost-effective than chemical grout - until the project location gets factored in. Dams are found in many remote locations. The very remote ones are often built using a temporary road that can handle heavy construction traffic. Fast forward some years and these roads no longer can support cement trucks or other heavy vehicles.

Chemical grouting equipment can easily be loaded into a pickup truck or even on the back of an ATV. While the material cost of polyurethane chemical grout is more than cementitious grout, getting polyurethane materials and equipment to a remote site can be a lot less expensive.

Lightweight polyurethane is much easier to mobilize with a small to non-existent footprint. This means it is less disruptive to sensitive sites. (Seawalls are a good example where chemical grouting can be done without tearing up the home owner’s yard with heavy cementitious grouting equipment.)

There are many factors to consider for every grouting job. It helps to have the Grout Geek and Alchemy-Spetec in your corner to help design the right plan for your project.

Loose, unstable slabs with voids underneath are often referred to as "rocking" slabs due to their movement when forklifts cross over them. Rocking slabs are a common problem in many warehouses. Left un-repaired, they can cause damage to equipment and injury to workers. Eventually, rocking slabs will require replacement if they are not repaired properly.

Rocking Slabs Can Cause:

• Slab Deterioration Over Time
• Floor Destabilization
• Damage to Material Handling Equipment & Loads
• Trip Hazards & Litigation Risk

How to Repair Rocking Slabs:

1. Inject high-strength, high-density polyurethane foam underneath the slab for lasting support.
2. The polyurethane expands to fill any voids underneath and cures to support 14,000 lbs/square foot.
3. Easily clear excess foam from the surface of the slab.
4. Repaired slabs are traffic ready in just 15 minutes!

Alchemy-Spetec products are proudly made in the U.S.A.  Manufacturing at the Tucker, GA, and Reno, NV facilities (rather than outsourcing abroad) provides three distinct advantages to you and to the country we all call home: consistent quality, reliable supply, and more American jobs.

Consistent Quality

With our industry experts overseeing the production process, products are manufactured to the exact same specs with the exact same equipment every time. Outsourcing to a rotating line-up of the lowest overseas bidders would force us to sacrifice these advantages.

Reliable Supply

Being in complete control of the facilities in which our products are made ensures a reliable supply of products (within the boundaries of raw material availability of course). Outsourcing would leave us (and you) at the mercy of overseas facilities conditions, which we have no control over. 

More American Jobs

One of Alchemy-Spetec's core company values is an appreciation for, and a desire to benefit, the United States of America. If manufacturing superior products in a controlled, reliable manner also happens to create more jobs for American citizens - all the better! That is what we call a win-win situation!

Polyurethane chemical grout injection can be a bit of a Pandora’s box at times. So, what can be done to help combat some of these uncertainties? Well, how about the easiest and most cost-effective solution first. Oakum! Not only is it amazing what you can accomplish with it, but it is vital to have on every job. YES, I SAID EVERY JOB.

There are only two things that have to happen for successful water mitigation. One, get the grout to the right location. Two, keep it there long enough to react. With tight cracks, it can be difficult to get the grout to travel in the crack, but once you get it there it is good to go. With wide cracks or high flow leaks, getting to the right place is easy, but keeping it there long enough to set up can be challenging.

You can use oakum to control grout and keep it where you want it in the crack or joint. Remember we are doing the injection work to stop the flow of water, so let’s make the least amount of holes possible in the concrete. But what does that have to do with oakum? Cracks are irregular, and often have sections that are wider in some sections. When this wider area is at the surface it can allow an easy escape path for a grout under pressure. That means you are wasting grout and not getting it where it needs to be, deep in the crack. Sure, if you have raw resin coming out of the crack you can just wait for it to cure. Once cured you cannot reinject that packer, so it is best to surface seal that crack and stop or slow down the loss of grout. This allows you to continue effective pumping into the crack or joint.

If the crack or joint is wide, grout impregnated oakum can be packed in place. While messy, this is the equivalent of finger painting with chemical grouts and is an easy process.

If you're thinking "I have rags, I don’t need oakum", think again. Oakum is stronger, can be pulled apart into just a few fibers if needed, and can be stuffed into very tiny defects where rags cannot fit.
