Why Slab Lifting?

Slab lifting is an economical alternative to complete concrete replacement, be it a simple sidewalk repair or providing a cost-effective remedy for an entire building foundation.

If you want to corner the market in this potentially profitable business, begin by scoping out a specialized area, such as residential, commercial, or civic/municipal.

Next, make a simple short written list of the assets you absolutely must have to get started. Do you need a full sized slab lifting rig to get rolling? Or maybe just the portable PolyBadger lifting system? (Review both options here.) Are there any special licenses or certifications required for operation? Do you have a good relationship with an equipment and materials supplier? Having the right slab lifting equipment, top-of-line materials, vendor support, and deep expertise in this unique industry are the first keys to success for startup companies.

Do You Have a Business & Marketing Plan?

If someone asked you to drive to Seattle, would you get in your car and take off, or would you look at a map first? A business and marketing plan is the roadmap for your slab lifting/concrete leveling business. It will help you define and stay true to your path, and it’s a tool you will need to attain startup financing. In it, you should define your target market segments, project revenues and milestones for the first 3 to 5 years in business, define fixed and variable costs, and outline how you plan to get the word out among potential customers.

Do You Have Vendor Support in Place?

Whether your goal is to launch a slab lifting venture that caters to home or business owners, you will need a dependable, knowledgeable supplier who will not only sell you slab lifting pumps, guns and foams - but also serve as a trusted advisor.

How Polyurethane Grout Injection Works for Stormwater Infiltration Prevention

During a period of heavy flooding, stormwater systems become more susceptible to erosion and the infiltration of polluted water. For municipalities, infiltration of polluted stormwater means costly treatment of water and infrastructure repairs to damaged pipes.

The Stormwater Infiltration Issue

• Ground water rising and falling puts hydrostatic pressure on pipe and manhole joints causing them to fail.
• Water flowing in and around catch basins and roadways causes soil to erode.
• Water flowing into failed joints erodes soil from around the infrastructure causing potholes, cave-ins, and loss of structural integrity of the storm water system. Pipes can become misaligned causing much more expansive problems. 

The Solution: Polyurethane Grout Injection

• Point grouting is a method of driving injection pipes to the points of failure and injecting a resin such as Spetec PUR H200.
• The resin expands and cures quickly to seal off the leaks and fill voids in the soil.

The Favorable Outcome

• Sealing the joints prevents further soil erosion.
• Filling the voids with a resin like Spetec PUR H200 reduces the hydrostatic pressure on the joints.
• The resin also permeates the soil and increases the load bearing capacity which can prevent future misalignment of the pipes.

Alchemy-Spetec is already known for providing the most powerful polymers and painless procedures contractors need to achieve the rapid results their projects demand.

However, on construction projects of almost any scope and size, ensuring the safety of public drinking water is also mission-critical. That's why the following Alchemy-Spetec' polyurethane resin products have received the official NSF seal of approval for contact with drinking water: 

AP Lift 430

AP Lift 475

AP Soil 600

AP Fill 700

Spetec PUR H100

Spetec PUR H200

Spetec PUR F400

Spetec PUR GT500

Spetec PUR HighFoamer

Spetec AG200

This single designation ensures compliance with the Safe Water Drinking Act (SDWA) and guarantees peace of mind for in-the-field stakeholders on construction projects of almost any scope and size.

The SDWA helps ensure the water we drink, bathe in, cook with, and use in myriad other ways in daily life is safe for consumption. The federal law was put in place to maintain public health standards for drinking water systems. It defines what is considered a contaminant – both man-made and naturally occurring; and outlines the agencies responsible for regulating, monitoring, and enforcing adherence to the law, primarily the Environmental Protection Agency.

The SDWA gives the EPA latitude to impose criminal and civil penalties on industries not in compliance. In 2014 enforcement efforts policing clean water netted $163 million in penalties and fines, 155 combined years of incarceration for sentenced defendants, and $16 million in court-ordered project clean-ups.

Because so many of those defined contaminants are pertinent to even the most basic construction projects – turbidity from soil runoff, leaching from PVC pipes, potentially harmful and corrosive chemicals, and more – understanding and adhering to the law is particularly important for industry stakeholders. Contractors and engineers must be able to confidently choose vendors whose products and services won’t become the source or cause of drinking water contamination either in the short or long-term. NSF certification offers assurance that such problems won’t occur or will, at a minimum, be addressed.

“NSF, an independent, private, not-for-profit, third-party certification organization founded in 1944, has developed numerous health-based certification programs and consensus standards including those that relate to drinking water,” reads an NSF compliance brief. “The purpose of its certification program is to promote public health and enrich the quality of life. Through its Council of Public Health and Health Advisory Board, which includes EPA health professionals, it obtains guidance in developing and maintaining programs and standards. NSF also partners with code councils to ensure ongoing compliance.”

The products Alchemy-Spetec offers that can help net the most reliable and cost-effective results for contractors. NSF-certified products and materials are evaluated and lab-tested, and production facilities such as our own are inspected and annually audited for re-testing to maintain certification.

Alchemy-Spetec voluntarily undergoing such a rigorous certification process is invaluable to customers because it provides assurance that, at the end of the day, our arsenal of products are not only the top-performers in the market, but also protectors of the environment.  Powerful polymers, painless procedures, rapid results!

Whether the culprit is poorly compacted or eroding soils, excess moisture from leaking HVAC systems, too little moisture brought on by drought, or just a sinkhole no one knew about until it opened its gaping maw, concrete slab settlement is a fact of both life in general and the construction industry in particular. And one that has to be addressed before it creates bigger, more costly issues.

Concrete slab lifting is a unique solution to this age-old problem. In a process also known as slab jacking, sinking concrete slabs are lifted and leveled, most frequently these days with the aid of a high-density polyurethane foam.

Though simple enough in theory, slab lifting is a fairly remarkable feat that allows residential and commercial property owners the option of repair versus a total rebuild. Below is a timeline of the early foundations of concrete, and how slab lifting has come to be a reliable, cost-saving means of putting sinking concrete slabs back on solid ground.

Historical Timeline of Concrete Slab Lifting

• 600 BC – The Greeks discover that volcanic ash, a natural pozzolan material, develops hydraulic properties when mixed with slaked lime. When stored underwater, the mixture’s strength increases.
• 200 BC – Romans “borrow” (sound familiar?) the cementious mix from the Greeks and continue to perfect it, adding gravel, sand, ground pottery shards – even animal products to the mix.
• 126 AD – Under the auspices of Emperor Hadrian Pantheon, the Romans complete the Pantheon, a circular temple of worship commissioned by Marcus Agrippa during the reign of Augustus. The pozzolana concrete and stone aggregate are used to construct the thick walls and 142-ft domed roof. The building still stands and the dome remains the largest unreinforced concrete dome in the world. However, time, settling soils, a few earthquakes, and other natural disasters have taken their toll and have caused cracking throughout.
• 1793 – John Smeaton is tasked with building a lighthouse on Eddystone Rocks in England. He tinkers with different mortar mixtures and discovers that the best ones are made from calcined lime containing a goodly amount of clay minerals. It’s the first time clay is mixed with lime for hydraulic-setting cement.
• 1824 – Inventor Joseph Aspdin mixes, experiments, scratches his head, then voila, creates and patents Portland cement – the basic ingredient of concrete. By 1897, Sears Roebuck is selling Portland cement in 50-gallon drums and urban settings evolve into so-called “concrete jungles”.
• 1900 – When the shifting sands and soils of terra firma meet the unbudgeable weight and heft of concrete, the laws of science and physics say the heavy always wins. By the turn of the century, “mudjacking” is the standardized means of leveling the playing field, as it were. Hydraulic pressure is used to lift concrete slabs and fill in the void areas with a mix of mud, limestone, and often, additional cement. Over time, this “solution” compounds the problem because it too sinks into degrading or shifting soils.
• Today – A slab-jacking technique using polyurethane foam affords big results with a small footprint. The foam is used to support sagging concrete, and application is relatively minor in terms of downtime. In most applications, the repair site is traffic -ready in about 15 minutes.

Concrete restoration and waterproofing contractors see so many different kinds of leaks out in the field that categorizing them into basic groups is not an easy task.  However, that’s what we’re going to try and do.  The reason for this is to demonstrate how just two products in your arsenal can accomplish 90% of leak sealing tasks.

Alchemy-Spetec manufactures a range of polyurethane resins for Sealing Leaks, Stabilizing Soil, and Lifting Slabs.  Today we’ll focus on Spetec PUR GT500 and Spetec PUR H200 to demonstrate the versatility and scope of leak sealing that can be accomplished with these two products.  To be clear, the leaks we are addressing today are leaks through concrete, below grade structures, and through the soil.

Leaks through concrete are generally going to be through cracks, joints, and honeycomb (areas in poured concrete of mainly course aggregate with voids in between).  Depending on water volume and pressure, and the size of the joint or crack, you are going to encounter weeping leaks, steady leaks, and gushing leaks.  And of course there are also the “sometimes it leaks” types of situations.  All of these can be stopped permanently with Spetec PUR GT500, Spetec PUR H200, or a combination of both.

Spetec PUR GT500

This flexible hydrophilic injection resin is very low in viscosity and is excellent for injecting into hairline cracks and standard cracks and joints up to 3/8” wide.  It bonds aggressively to concrete and handles any movement within the crack because of its flexibility.  Spetec PUR GT500 is a single component resin designed to penetrate deep into the cracks, react with the water, and seal the leaks.  Its reaction time is slowed down somewhat in order to allow it to migrate throughout the crack.  On larger cracks which are actively leaking, a little oakum or backer rod can be wedged into the crack to prevent the resin from running out before it sets up.

Spetec PUR H200

Because the rapid expansive properties of this semi-rigid hydrophobic resin make it great for filling voids, it’s also excellent for shutting down strong and gushing leaks up to thousands of gallons per minute.  The low viscosity of this product allows it to be injected into hairline and smaller cracks as well, but it is mainly used for stopping the big ones.  Use Spetec PUR H200 with an accelerator to adjust the set time according the conditions of the leak. 

Spetec PUR H200 is also an excellent product for the process known as “curtain grouting”.  For instance, earthen dams and ponds often have water migrating through the soil creating voids, water loss, and potential failure.  Grouting into the soil in a grid pattern can seal off this water migration.  The resin expands into the ground and penetrates through the fines, and then bonds well with the surrounding earth.

Spetec PUR GT500 & Spetec PUR H200

Sometimes a leak requires a combination of both products.  Here is an example from an actual job:

There was a below grade utility vault that housed valves for two sewer force mains.  There were 24” and 18” ductile iron pipes penetrating the vault to connect to the valves.  Around the pipe penetrations, a previous contractor had used clay and mortar to try and seal it, but the water table was about 10’ above the penetrations and it had blown out the seals.  The entire vault (14’L x 12’W x 20’H) would fill up with water within a few hours.

Once again, these basic products were all that was needed to stop the leak.  The new contractor punched holes into the side of the vault near the pipe penetrations and installed injection ports.  Spetec PUR H200 with the standard catalyst was pumped through the ports and the hydrostatic pressure of the water forced the reacting resin back through the pipe penetrations slowing the leak and then quickly sealing it off.  Because there is some vibration in a pipe, Spetec PUR GT500 was then injected in a circle around the penetration creating a flexible seal and shutting down any trickles.  In this case the water table was so high that as the polyurethane expanded and reacted with the water, it literally travelled up the exterior of the vault and came in through some unseen cracks and poorly sealed joints, sealing those issues off as well.

It's is easy to go into a product catalog and become overwhelmed by the array of choices.  But don’t over think it!  Two products, or a combination of both, may be all you need to get the job done.

Alchemy-Spetec products will now officially be promoted under the Leak Seal and Geotech lines.  As holds true with most mergers (Alchemy Polymers and Spetec formed Alchemy-Spetec in 2017), the integration of products and services can take time.  This rebrand will be reflected in two separate product catalogs.  One for Leak Seal products and one for Geotech products. We are confident that the two-catalog offering is the best solution for our partners and customers. 

Both product types are now easily discernible by the Spetec or AP nomenclature in which Spetec represents Leak Seal, and AP represents Geotech. 

The Geotech line encompasses all two-part rigid polyurethanes used for void filling, slab lifting, permeation grouting, and soil stabilization; as well as acrylic grout used for permeation grouting, and all associated pumping equipment and accessories. Due to the technical support requirements of geotechnical applications in terms of equipment use, accessory setup, and application technique, this line will remain a direct sale to contractors performing slab lifting and soil modification applications.  

Conversely, the Leak Seal line remains a distributor sale through our continued support of distribution partners.  The Leak Seal line encompasses all water-activated grouts, acrylic grouts, waterstop products, mechanical packers and ports, and all associated dispensing equipment.   Since structural repair products are also sold through distribution, they are included in the Leak Seal catalog.

If you have any questions about the Alchemy-Spetec Leak Seal or Geotech product lines, please contact Jim Spiegel at jspiegel@alchemy-spetec.com for further assistance.

As we move toward a more clear definition of the Spetec and AP product lines representing our Leak Seal and Geotech product lines respectively, we're making a couple of product branding adjustments effective this week (or as soon as current stock is depleted).

AP Seal 500 will be rebranded as Spetec PUR GT500.  We are also introducing a water-activated semi-rigid polyurethane foam injection resin to the leak seal line which will be known as Spetec PUR H200.  Both of these products feature NSF/ANSI 61-5 approval for contact with drinking water. 

Spetec PUR GT500 is the exact same AP Seal 500 product you know and love, but rebranded to fit in with the Spetec leak seal product line.  This single component, low viscosity, flexible hydrophilic polyurethane injection resin is optimal for sealing hairline cracks, pipe penetrations, and joints in concrete structures.

Spetec PUR H200 is a single component, water activated, hydrophobic, low viscosity, closed cell polyurethane injection resin. Because it expands twice as much and (with the right catalyst) sets up 2.5 times as fast as the Spetec PUR H100, it's an ideal leak seal solution for quickly cutting off high-flow, underground leaks.
