Body - Pool House Foundation Void FillGeotech specialists from Ground Consolidation Services were called into a job by a general contractor in Atlanta. A property owner was restoring a very interesting pool house in an upscale neighborhood. The pool actually sits atop and in the center of the pool house itself. During the initial restoration process, they discovered voids under the pool house foundation.

Powerful Polymer

The GCS crew recommended Alchemy-Spetec's AP Lift 475, a two-component, hydrophobic, structural lifting polymer designed for airport, highway, and railroad applications. It can be used to stabilize structures, fill voids, and lift slabs supporting tremendous loads. The real beauty of this material is its ability to be traffic ready in less than one hour.

Painless Procedure

The technicians used the compact PolyBadger pump system for this job since the location was not easily accessible with a slab lifting rig. The PolyBadger, manufactured by Alchemy-Spetec, is a tough and compact mobile cart system for pumping polyurethane resin. Using this pump, the crew was able to fill the voids at a relatively quick pace.

Rapid Result

The GCS technicians were out of the way and the restoration crew was able to start backfilling the area in a few short hours.

Body - Stabilizing Student HousingRecently Atlanta-based contractor Sitemix was called in for a highly urgent remedial project at a nearby university apartment building. A plumbing break quickly evolved into a bigger issue than just fixing some pipes. The breach resulted in large voids under the foundation slab that compromised the integrity of the entire structure. Sitemix answered the call and was immediately up to the challenge. 

Powerful Polymer

Alchemy-Spetec’s AP Lift 430 was chosen for the job due to its high density, high expansion rate, high yield, and cure strength. This two-component, high-strength, high-density, hydro-insensitive structural polyurethane foam is ideal for void fill and structural stabilization and void fill in situations like the one described above. AP Lift 430 weighs 2.75 – 3.25 pounds per cubic foot.

AP Lift 430 Data

Painless Procedure

The structural polymer was injected through the slab to fill the voids and compact any compromised soil.

Rapid Result

The project was completed in a half day while most of the occupants were in class. The GC was ecstatic to have this emergency resolved quickly and painlessly.

Posted by David Park on May 26, 2022 10:00:00 AM

Banner - Lift-Sunken-Slabs-&-Stabilize-Loose-Soil

Body - Lift-Sunken-Slabs-&-Stabilize-Loose-SoilMost property owners and managers don’t realize that the greatest threat to their slabs and structures hides underneath the surface of the ground. Water is relentless, and your property is at risk if it is left unchecked. Uncontrolled water can lead to soil erosion, voids, and sometimes even sinkholes. Neglecting these types of soil issues can end up costing significant money, time, and stress.

We believe that every property owner and manager should understand how to prevent these problems from getting out of control. Water must be controlled properly, and with the right solutions. Alchemy-Spetec offers a variety of polyurethane resins for lifting sunken slabs, stabilizing soil, and filling voids underneath foundations and slabs. We are a global manufacturing company certified to ISO9001. Our polyurethane resin technology has been successfully used on a multitude of projects spanning the globe. It's also environmentally friendly (NSF certified for contact with drinking water).

Raising & Lifting Concrete

Sunken concrete slabs can be lifted back into place with our two-component polymer foams designed to work in wet or dry conditions. The expansion force of the concrete leveling foam coupled with the pressure of a specialized pump generates enough controlled force to lift virtually any structure back into position with 1/8” precision. Polyjacking (a.k.a. slab lifting and concrete lifting) can be accomplished at a fraction of the cost and time required for replacement using our AP Lift series of resins. The Deep Lift® process may be necessary if deeper soil issues are undermining the slab or structure.

What Is Polyurethane?

Posted by Brian Dalinghaus on Mar 31, 2022 10:00:00 AM

Banner - What is Polyurethane

Body - What is PolyurethaneThis post is part of the Alchemy-Spetec Contractor Lens series, featuring views, news & case studies written by our customers. This article, written by Brian Dalinghaus of Dalinghaus Construction, provides an overview of polyurethane concrete repair material. 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.com today!

Perhaps a foundation repair contractor has suggested polyurethane foam for deep injection, void fill, or slab lifting/leveling, but you’re not so sure about pumping “plastic” into the earth or underneath your home. You’re probably wondering: is polyurethane environmentally friendly? Is it effective?

If you’re concerned about the use of polyurethane for foundation repair and soil densification or just want to know more general information about PU, this article is for you.

Dalinghaus Construction Inc. has been in the foundation repair game since 2015. We have over 100 years of combined foundation repair experience and have serviced thousands of foundations in Southern California and Arizona via polyurethane-related repairs. We know everything there is to know about polyurethane and we’re here to share.

In this article, you will learn the definition of polyurethane, its history, many general uses, and how polyurethane foam is utilized in foundation repair.

What is Polyurethane?

Before you pump gallons of polyurethane foam underneath your home or into the soil around your property, you probably want to know what exactly it is.

Polyurethane Definition

Polyurethane is a synthetic resin compound comprised of carbamate/urethane groups linked to polymer units, often abbreviated as PU or PUR. In other words, polyurethane is a combination of chemicals/compounds that react to create a plastic-like substance. As a solid, polyurethane has an open-cellular structure – which is a foam.

Polyurethane foam, utilized for many purposes including insulation, sound-proofing, and foundation repair, is created by the chemical reaction of Diisocyanates and polyols (both of which are derived from organic crude oil). Because polyurethane is comprised of organic material, it is environmentally friendly and does not contribute to an increased eco-footprint.

Polyurethane is not a plastic. Technically, the elongated flexible polymer molecules that make up thermoset polyurethanes categorize this material as an elastomer (a natural or synthetic polymer having elastic properties, e.g., rubber).

Polyurethane foam is a safe, eco-friendly option to densify weak, non-load-bearing soil, void fill beneath your foundation following a lift/stabilization and relevel slabs.

History of Polyurethane

Polyurethane was invented in 1937 by the renowned German Professor Dr. Otto Bayer. Dr. Otto Bayer was an industrial chemist and worked for IG Farben – spearheading the research team that discovered polyaddition (the key to synthesis for polyurethanes by combining polyol and polyisocyanate).

Polyurethane first enjoyed widespread use in World War II as a rubber substitute. Polyurethane was utilized as airplane finishes, various coatings, and to create flame-retardant clothing. By the 1950s, Polyurethane was utilized for many different applications: couch cushion foam, rigid foams, elastomers, and adhesives.

Today, polyurethane is utilized for a wide variety of applications: mattresses, shoe soles, car seats, insulation, and even pacemakers. Polyurethane is a “behind the scenes” product, often hidden behind a layer of fabric, plastic, or other encasing material.

Due to its prevalence, in everything from car seats to pacemakers, it’s truly difficult to grasp the full scope and impact of polyurethane in everyday life – however, its importance in the foundation repair game is easy to explain.

Polyurethane and Foundation Repair

The foundation repair industry uses polyurethane foam primarily for soil densification, void fill, and lifting/leveling slabs back into place. Polyurethane foam is an injectable polyol and isocyanate resin sealant, insulation, grout which expands upon application providing void fill, structural support, and re-leveling properties.

The polyurethane foam is installed via an application gun: the polyols (a type of alcohol, containing multiple hydroxyl groups) and diisocyanate/polymeric isocyanate are pumped separately, but simultaneously. The chemicals combine and react after exiting the application gun.

The foam then expands, filling the void, densifying the soil, or lifting the slab back into place. In short, polyurethane has incredible expansive properties, allowing it to fill voids evenly and with ease – providing strength and support to the affected structure.

Here at Dalinghaus Construction Inc., we use Alchemy-Spetec's AP Lift 430 (which has been certified by Truesdail Labs to NSF/ANSI 61-5 – meaning it’s approved for contact with drinking water).

AP Lift 430 is:

  • Waterproof (Hydrophobic)
  • Noninvasive (Install Process is More Efficient and Replacing Concrete)
  • Nonpolluting (NSF Approved for Contact with Potable Water)

In addition, AP Lift 430 weighs approximately 3 pounds per cubic foot and reaches 90% compression strength in only 15 minutes. And, finally, polyurethane can hold 7,200 pounds per square foot. In short, polyurethane is a fantastic solution for foundation repair and hillside stabilization needs.

Polyurethane Foam is Safe, Effective, and Environmentally Friendly

In this article, you learned the definition of polyurethane, how it was invited by Dr. Otto Bayer, the wide spectrum of uses, and how polyurethane foam is utilized in foundation repair and construction. You also learned that polyurethane is a safe and effective product. Dalinghaus Construction has helped hundreds of homeowners and offers an array of services, including carbon fiber crack repair, steel pier underpinning, and more.
