Comparison between Uretek Method and Mud-Jacking


FROM THE FIELD
A corner of our basement was dropping substantially. I hired a mud-jacker. It is a messy process, and very loud. They drilled 3" holes in my slate floors. Not even a year later the basement was sinking again. I hired a more expensive mud jacking company. They repeated the messy process and lifted again.

The next year I noticed sinking again! An engineer recommended CST and their Uretek product. CST performed tests to know how deep to inject. Their holes were so small (1/2") they could drill between the slate tiles—you cannot see them unless you really look. There was little or no mess. They put their material under the foundation at deeper levels. It expands and hardens.

Over a year later, I am happy to report that I have no sinking. I would not hesitate to recommend CST and their Uretek treatment. They dealt with me fairly and honestly and they stand behind their work. It was more expensive than mud jacking, but now I won't have to do this every 12 months.

The least destructive and post practical method to fill voids beneath slabs, stabilize underlying soils, and lift slabs is to inject polymer material such as Uretek beneath. CST can complete this locally.

– Zack S., Engineer, Gypsum, CO

Thank you for the high quality work you did on the water control project for our client. The job was completed in a timely manner at a fair price. Your crew was organized and showed expertise in this matter. Our client is happy, and we are able to stay on schedule with our project.

– Nate T., Contractor, Park City, UT

The professionalism, knowledge and patented process convinced us. You never failed to do what you promised. Your estimate was timely, and your crew showed up as scheduled. CST finished the job in less time than estimated. The garage floor was lifted 5? inches. We parked 3 vehicles in it that night! Not only that—my husband has no complains, which says it all!

– Carolyn M., Littleton, CO

CST went the extra mile to do the best possible job. The crew were the best, and the results proved it. I would use them again!!!

– S.M., Leadville, CO

I thank you for the professional was our work has been handled. We are certainly pleased with the outcome. It's refreshing to deal with a company that stands behind their name and product when problems do arise. This is a rare commodity in today's market.

We are quite impressed with your technology and would not hesitate to give a glowing recommendation to anyone in need of concrete lifting.

– Barbara P., Lakewood, CO

I am impressed and satisfied with the service you completed for one of my clients. Your crew are talented and professional tradesmen. They were efficient and delightful to work with. Knowing how your system and product work, I don't know why anyone would use anything else.

– Marc E., Contractor, Centennial, CO

We have had two opportunities to compare removal and replacement to CST's ability to restore settled concrete panels. The rip and replace method took 3 days while we waited for concrete to gain strength for traffic loads. The closure resulted in phone calls from businesses, distressed motorists, and concerned citizens.

With CST's repairs, traffic was back to normal in a few hours. We repaired 3 locations in two days, and the actual cost was less than estimated.

Comments on the Uretek Process
  1. Unlike light-duty foams used for insulation or dry void fill, our material is a heavy-duty (industrial strength) material that is impervious to water. Light-duty foams become spongy and weak in the presence of water.
  2. The State Department of Transportation (true in all states we serve) uses this exact technology to repair bridge approaches where long-term performance is essential.
  3. The material is injected through a tiny hole about the size of a penny. When we're done, we fill that hole with non-shrink grout, so the repairs are almost imperceptible.
  4. The two-part material at the time of injection is in a liquid form at about the consistency of motor oil. Therefore, it flows very easily into a wide pancake underneath the slab.
  5. As the two-parts mix together, they form a creamy-foamy state that has enough expansive power to fill voids and fissures beneath the slab. This gives better support to the slab than with older technologies.
  6. The Uretek Deep Injection® method also addresses the main reason for settlement in the first place—the density and bearing strength of the soil beneath. Where needed, we literally use the powerful expansive characteristics to compact the soil beneath the slab.
  7. The Uretek Deep Injection method can also be used to stabilize foundations, repair soils, divert water, and fix leaks. This often can be a substitute for piers.
  8. CST is the region's most experienced expansive polyurethane contractor having completed thousands of successful jobs for homeowners, commercial properties, industrial and warehouses, truck stops, schools, colleges, universities, airports, municipalities, counties, and state and federal government agencies.
  9. We also offer Helical /Push Piering, Water control, leak mitigation, expansive clay stabilization, and other technologies.
  10. CST is one of the region's most reliable specialty contractors. We utilize the most effective high-tech solutions available. We are committed to quality work, true customer satisfaction, and the promise that we will get the job done right!

Problems with Other Contractors:
  1. Small contractors are here today, gone tomorrow. CST has been providing quality services for over 13 years.
  2. Other contractors charge you for a job evaluation. CST provides that service at no additional charge.
  3. Most would-be poly-lift contractors have very little experience with these high-tech solutions. The key to a quality job is well-trained, experienced technicians. Our senior techs have over 13 years field experience. We know what to do and how to do it.
  4. We have the full backing of the Uretek brand—internationally known and recognized leader in polyurethane injection, with unique processes and methods that are protected by patent. We're the only contractor in the region with the Uretek license.
  5. Most engineers today recognize the limitations of mud-jacking, and do not recommend it over polyurethane lifting technology.
  6. Older technology (cementitious grout) has four main problems. First, the mix consistency during injection is hard to control thus has potential for inconsistent performance. Second, virtually all CG utilizes water, which tends to exacerbate existing soil settlement problems due to weight and shrinkage. Third, attempts to utilize less water in a CG mix often makes the mixture hard to inject and move under slabs. This causes point-loading. Fourth, the method of CG injection is via hydraulic power which can often threaten footings, foundations, and retaining walls.

Environmental Issues
Is our formulation of HD polyurethane safe for the environment?
Yes. All materials are 100% environmentally friendly. There is no pollution of the environment or surrounding groundwater. In its cured state, our material is completely non-toxic and inert. That's why this technology is approved for use by the U.S. Forest Service, BLM, State and Federal Parks, and recreation districts throughout the United States. This new technology is also preferred because tearing out existing concrete often increases landfill waste. The process saves fuel consumption because of speed and non-disruption. There is less noise pollution and drastically less airborne debris using this process.

What's the Difference Between the URETEK Deep Injection Method and Mud-Jacking?

PROBLEMS WITH MUD-JACKING
Concrete lifting and soil stabilization problems are often addressed using high-pressure grout systems. These older technologies can be less desirable to the URETEK Deep Injection Method. Here's why:
  1. Grout (mud-jacking) uses water, even those claiming to be non-shrink. Water can increase settlement problems.
  2. Injecting water-laden grout into the soil increases potential for future erosion. It also shrinks as it dehydrates.
  3. Grout enters the ground under high pressure. This can potentially cause damage to retaining walls or irrigation.
  4. Cure time for grout can be up to 30 days or longer. This can inhibit use of repaired areas.
  5. Injection holes drilled in the concrete can be from 1-1/2 to 2-1/4 inches wide—not aesthetically pleasing and potentially damaging to structural elements.
  6. Usually, because grout quality is variable, no material guarantee exists.
  7. No soil stabilization beneath the slabs is addressed.
Our new, patented URETEK Deep Injection Method is a much better solution—Success in over 75,000 installations!
  1. We use no water—therefore no additional soil problems are created.
  2. URETEK® material is a closed-cell formulation—water resistant—t under-seals concrete from water!
  3. URETEK expanding polyurethane material cures very quickly—your concrete is usable in 15 minutes!
  4. The URETEK Method causes virtually no disruption and leaves no mess.
  5. Our method is very fast. Many slab-lifting jobs can be completed in 1 day or less.
  6. We drill a very small injection hole (5/8" – size of a penny). When completed, you can hardly tell we've been there.
  7. We also address soil issues by injecting through probes to increase the soil bearing capacity.
  8. Our material is guaranteed for 10 years. When cured it's completely inert and environmentally friendly.
Last of all, the URETEK Deep Injection Method offers greater long-term value. Compared to poorer grouting methods with a 2-3 year life, our method is designed to last! So your cost per year could be 30-40% less! When you consider speed and low-disruption factors, we're definitely the right choice.

With so many advantages, the URETEK Injection Method has now become the preferred solution for concrete-lifting problems for real estate management professionals, businesses, schools, municipalities, and even homeowners.
