This post is part of the Alchemy-Spetec Contractor Lens series, featuring views, news & case studies written by our customers.  This article, written by Robin Smith of Dalinghaus Construction, contrasts the methods of polyurethane slab lifting vs mudjacking.  If you're an Alchemy-Spetec customer and you'd like to discuss writing content for our blog, please send an email to marketing@alchemy-spetec today!

Have a sinking slab you need to lift? Here at Dalinghaus we offer Polyurethane Slab Leveling, but we often get calls from customers asking for something called “Mudjacking”. If you follow us online, you have gotten an opportunity to learn a lot about Poly, but might not know anything about mudjacking. We are going to break down some of the basic differences between them! You do have options! So let’s take a look at Poly VS Mudjacking, and see what looks better to you.

What is Mudjacking???

Mudjacking is the process of lifting a building, driveway, or any slab of concrete by pumping a mixture of concrete and water (known as mud to people who work with it) underneath a sunken slab raise it back to a level or a predetermined lift. The process of mudjacking settled concrete has been around for over 60 years, and as such, the issues with the process have been well documented. Some of those issues include:

  • Weight Of Material: The weight of the “mud” material can be as much as 100lbs per cubic foot! (Compare that to Polyurethane that comes in at about 2-4lbs per cubic foot!) Typically a slab starts sinking in the first place because the soil around it has been compromised. The added weight of the concrete can cause further settlement. Why fix a problem with something that potentially adds to the problem?
  • Big Holes In Your Concrete: Mudjacking requires drilling a 2-3” hole through your slab to pump the thick material through. The number of holes needed is dependant upon the condition of the concrete. (Compare that to Poly that only requires a ⅝” hole to inject material!) These holes then need to be patched, and they tend to stick out like a sore thumb. 
  • Curing Time: The concrete that is pumped under the slab isn’t exposed to the sun, it takes longer to cure. It can take days to a week to dry! (Our Polyurethane sets up in just seconds! Check out this project that we completed at the Orange County Transit Authority. Our technology was able to keep the bus schedule on track without missing a beat!)

When it comes to Poly VS Mudjacking, Poly makes WAY more sense to us! If you want to learn more about how we can help you, give us a call!

Banner-How to Add Slab Lifting Capability to a Spray Foam Rig

Body-How to Add Slab Lifting Capability to a Spray Foam RigWe often get calls from spray foam insulation installers who are interested in adding slab lifting capability to their rig set up. If you're reading this article, you yourself may be looking for info on the matter. If so, we have good news for you. With just four additional pieces of equipment and one set of material, you can quickly and easily add slab lifting to your service offerings. Let’s take a look at exactly what additional equipment and material you'll need to get started...

Slab Lifting Equipment

MixMaster Pro Slab Lifting Gun
The MixMaster Pro is a two-component resin injection gun manufactured specifically for lifting concrete slabs, designed to handle back-pressure. 

Titan Impact 440 (Modified) Pump with Flush Hose
The Titan Impact 440 (Modified) pump is used for flushing the MixMaster Pro gun in between foam injections. (It's also used for pumping one-component material in soil stabilization and seawall repair applications.)

3/8” MixMaster Ports
These heavy duty ports create an airtight seal for injecting foam into drill holes. 

Dial Indicator Crane
This precision tool is used to measure the lift of the slab within 1/10” of an inch.

Polyurethane Slab Lifting Material

AP Lift 430, AP Lift 440, or AP Lift 475 (100 Gallon Unit)
Sunken concrete slabs can be lifted back into place with these two-component polymer foams designed to work in wet or dry conditions. The expansion force of these concrete leveling foams coupled with the pressure of a specialized pump generate enough controlled force to lift virtually any structure back into position with 1/8” precision.

Develop Your Competitive Edge

Posted by Michael Binyaminov on Apr 16, 2020 10:00:00 AM

Banner-Develop Your Competitive Edge

Body-Develop Your Competitive EdgeWhenever I talk to contractors who are in the market for a polyurethane materials provider, I always find myself discussing the same set of important points.  In a nutshell, I end up sharing my appreciation for the unique ways in which we can help contractors develop a competitive edge. In order to make this info available to a wider audience, I've decided to write it all up in a brief blog post.

Polyurethane – Quality and Selection

Alchemy-Spetec offers one of the most technologically advanced grout product lines currently on the market, including our unique, highly-effective Spetec PUR HighFoamer. Known in the industry for its expansive properties, this product is the only one in its class that can shut down gushing leaks and fill voids as quickly and effectively as it does. We offer a wide variety of materials, including slab lifting foams, deep-soil lifting foams, soil stabilization foams, injection resins for crack leak seal, foams for curtain grouting leak seal, acrylic injection resins that penetrate thin cracks and saturate soil, epoxy resins for structural repair and preventative waterstop products. The superior quality of these materials guarantees fewer callbacks from your customers. Many of these products are also certified for contact with potable water, making them safer for the environment.

Equipment and Accessories Selection

We’re a one-stop shop for all things polyurethane concrete repair, with one of the most versatile equipment and accessory product lines in the industry. Once you’ve picked out the product that best fits your needs, we can provide it all: pumps, hoses, packers/ports, and specialty accessories.

Tech Support – Experience and Dedication

Do you need technical support? You’re in luck—we’re home to the industry’s premier technical support squad. Averaging decades of experience, we also pride ourselves in being incredibly responsive. For example, our team was recently called on to assist with a large metro project in the Western United States. The customer informed us at 4pm on Monday evening that assistance was needed at 9am the very next day! Our Technical Services Director Charlie Lerman, Vice President Jim Spiegel, and Western Regional Sales Manager (that's me!) traveled to the site Monday evening to help diagnose the location of the leaks and develop an action plan. Our Technical Services Manager Charlie remained on site for two more days to ensure that the project was successful. Depending on the size and scope of the project, response time and participating team members may vary, but this story serves to illustrate the lengths we will go to assist customers.

Training and Education

We offer the industry's most thorough training and education for both Leak Seal and Geotech polyurethane infrastructure repair. We conduct training workshops at distributor locations, consult with contractors on job sites, and hold intensive programs twice a year at our headquarters in Tucker, GA. We also offer in-depth online training videos to current customers.

Marketing Support

Our Marketing Department provides qualified customers with product application illustrations and photos for use on websites, customized brochure PDFs for printing, and truck signage graphics. We also offer the use of our educational videos and animations. Lastly, we’re available for guidance on everything from online lead capture strategies to internet advertising, and more.

We’re Committed to Your Success

The overriding theme here is our commitment to your success. Obviously, this is not totally altruistic in nature.  The more successful you are, the more materials and equipment you buy.  But it is 100% genuine.  Our entire team understands the relationship between YOUR success and OUR success.  This point of view is thoroughly ingrained in our company culture.

Case Study – Leveling Sunken Slabs in a Pole Barn

Posted by Erik Prinzing on Mar 31, 2020 10:00:00 AM

Banner - Leveling-Sunken-Slabs-in-a-Pole-Barn

Body - Leveling-Sunken-Slabs-in-a-Pole-BarnI'd like to share a case study from a recent job that I consulted on with one of our contractor customers, ETRU Spray Foam and Coatings and Coatings in Southern Illinois.

A 25’ x 40’ residential pole barn in Carbondale, Illinois was built on a 6” floating concrete slab on grade. The concrete was poured into four 10’x 25’ sections. Each section had multiple cracks and breaks throughout, and in some cases, the broken sections had a drop of up to 3”. During the inspection, it was discovered that the pole barn 4 corner beams were driven into the ground and the concrete poured around them. The front of the property was pitched towards the pole barn and it showed no signs of ever having gutters and downspouts attached. After drilling an injection hole, we inserted a probe to check the depth of the void and the stability of the ground. In some areas the void was 6” and the probe was hand driven to a depth of 3’ before hitting hard ground. ETRU Spray Foam and Coatings was hired to stabilize the ground and level as much of the concrete as they could. The homeowner plans to utilize the space as a game room.

Powerful Polymer

Among the most dependable products for geotech applications, AP Lift 430 structural foam provides an exceptional DOT grade solution for these types of situations. This 3 lb. density, high-strength, hydro-insensitive structural polyurethane foam is perfect for densifying soil and lifting concrete slabs.

Painless Procedure

The ETru crew and I walked the project with both property owners. We pointed out how waterlogged the ground was and that they needed to add gutters and downspouts, as well as pitch the ground water away from the pole barn. We also talked about possible blowout from under the slab during the injection process and how to handle it. I worked with ETRU to draw up a plan, indicating exactly where the injection points would be located (knowing that the plan might change due to the ground moisture and the number of voids to be filled). All injections were completed from inside the pole barn with a crew member on the outside to alert us when product broke through the ground. First, we injected in the back corner which had the 3” drop. The plan was to establish a base slab height on the side with the most soil problems and then level everything else to that slab. Spacing between injection points was approximately 3-4 feet, with 38 total injection locations.

Rapid Result

The ETRU Spray Foam and Coatings crew achieved a three-inch lift and was able to bring all the other slabs within 1/8” from the adjoining slab. The customer was extremely happy with the results.

The MixMaster Pro slab lifting gun was designed based on years of feedback from slab lifting contractors working in the field. Every known point of frustration and difficulty has been addressed in this sturdy, single-purpose gun. Further benefits include a lower cost of consumables (you can reuse ports with this gun), beefy check valves designed to handle the back pressure, and a short 10-minutes or less breakdown/cleaning session at the end of each day.

This gun is also is a production BEAST - no leaky port connections, no fumbling with clamps. Watch your man hours on each project shrink accordingly. Did we mention you’ll have less replacement part orders? There are only a few inexpensive replacement parts on this gun - PERIOD.

Ask about the quick 10-minutes or less breakdown/cleaning session on the MixMaster Pro at our World of Concrete 2020!  Drop by to see us at our Geotech Exhibit Space - # O40551 in the Silver Lots (same location we were in last year). 

There will be a LOT to see and do at our Geotech space this year:
