Stabilizing a Pool Deck and Wall with Spetec PUR H200

Today’s guest blogger is Bill Stivers, an experienced salesman at Alchemy-Spetec distributor Sunshine Supply.

As a Salesman at Sunshine Supply, I’ve dealt with a lot of leak seal products over the years.  But I don’t often get the chance to try them out on my own property.  I recently, however, had an issue with a leaking swimming pool in my own back yard.  Water was draining through the seams between the slabs of my pool deck and causing erosion.  In addition, ground squirrels and rabbits had been digging around the area over the years, causing further issues with soil displacement.  The pool deck was destabilized along with the wall surrounding the pool.  They had both slipped about a half an inch down a small hill on one side.  Some bricks around the pool had settled about 2 inches.  My extensive experience in this field told me that this was just the beginning of a much more serious problem.  The leaking water had to be contained and the soil around the structures had to be stabilized immediately.

Due to my position at Sunshine Supply, I am familiar with a wide range of leak seal products, and there was one that I knew would be ideal for this job: Spetec PUR H200.  We injected deep into the soil on the hillside via 6-foot injection pipes.  We used an F-Valve to simultaneously inject water along with the resin to jump-start the reaction process.  (The wet soil would have caused the resin to react anyways, but the added water kick started the reaction process for a quicker install of the material.)  This process prevents the wall and pool deck from further slippage by stopping the seeping water and stabilizing the supporting soil.

If you live in any of the following areas and want to buy your leak seal supplies from distributors with expert knowledge of the products, make sure you contact Sunshine Supply at any of the following locations:

Alchemy-Spetec Geotech Resources

Posted by Andy Powell on May 17, 2019 3:25:43 PM

Alchemy-Spetec Geotech Resources

Alchemy-Spetec Geotech ResourcesSinking slabs and soil issues can cause both safety and property value problems. Alchemy-Spetec offers solutions for unlevel concrete and unstable soil.

Concrete Leveling

A structure is only as good as the foundation it’s built on. And regardless of how well-constructed a structure may be, most foundations settle. That’s just a fact of life. Erosion, shifting soil, compaction, and many other environmental conditions tend to cause settling. Sometimes structures settle gradually, and in other cases they’re swallowed up in minutes. These situations create problems for property owners and opportunities for the contractors who know how to fix them.

Alchemy-Spetec manufactures high-strength polyurethane lifting foams for slab jacking. Among the most dependable products for jacking and leveling concrete slabs, these two-component, high-strength, hydro-insensitive structural foams serve as an extremely effective solution for contractors.

Deep Lift Structure Leveling

Poor compaction, water erosion, broken pipes, and organic material in the soil can all lead to
settling of a foundation or a roadway. Traditional slab lifting can bring concrete and structures
back into place but it doesn’t necessarily address the underlying issue or guarantee a long
term fix. Other methods of addressing deep soil issues require heavy equipment, extended
down time, and collateral property damage. These situations create problems for property
owners as well as opportunities for the elite contractors that know how to fix them.

Alchemy-Spetec offers a unique combination of high-strength polyurethane structural lifting foams along with the equipment and training needed to address deep soil issues. Now you can achieve soil densification and lifting on large projects with the smallest footprint and least amount of heavy equipment required.  The Deep Lift™ process is powerful, painless, and rapid. Deep Lift™ gets to the root of the problems in the soil, it brings the structure back to level, and accomplishes this with minimal imposition or downtime to the property owner.

Soil Stabilization

Unstable soil can be defined as soil that will not stay in place on its own, and therefore requires
extra support. It should be noted that unstable soil can threaten the stability, security,
and safety of infrastructure and can damage, degrade, and even destroy a number of structures,
such as buildings, bridges, and roads. There are a variety of factors that can cause unstable
soil including erosion, poor compaction, freeze/thaw cycles and decomposition.

Soil can be stabilized high strength polyurethane stabilization foams.  Once the bearing capacity of the
soil has been increased with this process, then the structure can be lifted if necessary.

Advantages of AP Lift 430 and AP Lift 475

Posted by Andy Powell on Apr 17, 2019 2:37:31 PM

Advantages of AP Lift 430 and AP Lift 475

Advantages of AP Lift 430 and AP Lift 475Everyone claims their lifting foam is "the best" on the market (unless they're claiming theirs is the cheapest - which is a red flag to look into the quality ASAP).  As a quality leader in the industry, we provide more than vague statements and marketing slogans on this issue.

Here's a detailed list of the advantages you'll enjoy with Alchemy-Spetec's AP Lift 430 and AP Lift 475 lifting foams:

No Recycled Materials

The products are made of virgin raw materials only. They are consistent and clean, with no particulates floating around.

Water Blown Formula

Your drum set of material will be consistent from top to bottom. Whether you pump it all in one day or all in one month. No mixing will be required.

Lower Exotherm

You'll be able to fill voids, stabilize soil and lift slabs faster.  In addition, unlike some other foams out there, these foams have no history of smoke or charring.

Cured Foam is Safe for Contact with Drinking Water

These foams are certified To NSF 61-5.  That means that the cured foam is safe for contact with potable water.  Most of the time your foam won't ever come into contact with drinking water, but this certification assures your customers that once the foam cures it will not pose any kind of environmental or health hazard.

Consistent Quality

You won't have to worry about your foam setting up one way this month and another way next month.  The NSF certification and the ISO 9001 certification require the exact same formula for every single drum set.  We have both certifications.

DOT Grade Polyurethane Foam

DOT grade foams cure faster, work in wet conditions, and are traffic ready in 45 minutes.  Use less material and get less call-backs with foams that meet the standards for Department of Transportation work.

Stabilizing Slabs to Prevent Sinking Before It Starts

Posted by Andy Powell on Apr 1, 2019 2:05:52 PM

Stabilizing Slabs to Prevent Sinking Before It Starts

Stabilizing Slabs to Prevent Sinking Before It StartsSlab stabilization and structural void filling can actually be even more valuable than slab lifting. Why wait for a slab to sink, settle, or break, when it can be stopped. Preventative slab stabilization and underslab recompaction (I'm making up words now) is a great way to protect the investment that is the foundation of any home or business.

A good contractor should know how to: spot the signs indicating a possible problem, verify whether a problem exists or not, and repair an unsupported slab that’s in danger of sinking.

How to Spot a Slab That May Be in Danger of Sinking

The most obvious slabs at risk are the ones where a void can be seen from the side. In these instances, the soil on the side has washed away along with significant soil underneath. (See the photo included with this blog post for an example.) Other situations to look out for are slabs on a hill or at the bottom of a hill. Concrete in these locations is likely to have rain water washing under it and eroding the soil. Slabs on level ground aren’t immune from this problem either. Check for gutter downspouts placed very close by, or adjacent structures with no gutter system at all. If a rain water management system wasn’t set up to direct water AWAY from the slab, there may be an issue. Another red flag would be cracks in the concrete.

How to Be SURE a Slab’s in Danger of Sinking

There are many ways to check for voids underneath a slab. Some people tap the slab with a metal tool, or even a golf club. (Others use golf balls, which they bounce off the slab). Whatever the tool, the point is to listen for a hollow ring. This tactic may take some practice at first, but many people use it. Another approach is to drill a small hole, and then check the soil underneath with a soil probe or a penetrometer. I find that the 4’ long fiberglass driveway markers make a nice probe.  Endoscope cameras are small enough to stick down through the drill hole and have a look around. On larger jobs, some have arranged for the use of ground penetrating radar.

How to Stabilize a Level Slab in Danger of Sinking

On a void fill/stabilization job, the contractor should set up an even grid pattern across the entire slab. This approach allows for the even distribution of material, as needed. Unlike a lifting job, there’s no need to emphasize one side of the slab versus the other. Instead, the contractor injects the appropriate amount of resin into each hole of the even grid pattern. It’s important to monitor every injection with a zip level or dial indicator and stop at the first sign of any movement. If ANY slight movement happens it’s time to move on to the next hole. These tools allow for the detection of movement as small as 100th of inch, which isn’t a visible lift to the naked eye. For more on stabilizing slabs, see the blog post Slab Void Fill with Polyurethane Foam.

Wrap Up

No property owner should assume that their slab is safe just because it isn’t sinking yet. It’s better to know the danger signs and call a qualified professional to check it out. In addition, contactors should always keep an eye out for concrete in vulnerable situations. Remember: just because it’s level doesn’t mean it’s safe.

Concrete Leveling to Prevent Trip Hazards & Litigation Risks - Part 2

Posted by Andy Powell on Mar 22, 2019 10:00:00 AM

Concrete Leveling to Prevent Trip Hazards & Litigation Risks - Part 2

Concrete Leveling to Prevent Trip Hazards & Litigation Risks - Part 2In the previous installment of this two-part series, we looked at common slab settlement danger zones, causes of sinking slabs, and the many risks of neglecting a known trip hazard. This time around we’ll review the two most common non-polyurethane repair options, and then explore the three most common types of polyurethane slab repairs.

Non-Polyurethane Repair Options

Aside from polyurethane repair, the property owner has two other options: replacing the slab or mudjacking it with cement grout.  There are drawbacks for both.

Tear Out and Replace

Ripping out a slab and putting in a new one has three main disadvantages.  Namely, the process is…

  • Environmentally unfriendly (landfill bound?).
  • Messy (requiring heavy equipment and possibly damaging the surrounding area).
  • Time consuming.

Mudjack with Cement Grout

Concrete Leveling - Cement vs PolyurethaneMudjacking may be less expensive than replacement, but the property owner is still facing a number of issues.

  • It’s still a messy process.
  • Cement grout washes out.
  • The grout is heavy and can sink over time.
  • The grout can crack and shrink over time.
  • Not an impermeable water tight solution.

Structural Polyurethane Repair

Polyurethane repair has distinct advantages over replacement and mudjacking.

  • Very clean installation process.
  • Lighter than cement mudjacking grout and won’t sink over time.
  • Will not shrink.
  • Closed cell structure makes it water impermeable.
  • Typically less expensive than replacement.
  • Less time consuming to apply than a mudjacking or replacement solution, and ready for traffic 45 minutes after application.

Not to mention the strength of these polymers. For more on that subject, see our blog post Slab Jacking with Polyurethane Foam - How Strong is Strong Enough?

Trip hazard repair with polyurethane resin can require one or a combination of the following three approaches: lifting, soil stabilization and void fill.  Let’s take a close look at all three…


Sunken concrete slabs can be lifted back into place with a-two component structural polymer foam designed to work in wet or dry conditions. The expansion force of the foam coupled with the pressure of a PMC proportioner pump can generate enough controlled force to lift virtually any structure back into position within 1/10” of the intended level.

Soil Stabilization

Unstable, eroded, or loose soil below infrastructure can result in settlement, damage to the structure above, and of course – trip hazards. Voids can be filled, soil consolidated, and water migration halted by permeating the soil with one of our ultra low viscosity polymer resins. Once the bearing capacity of the soil has been increased with this process (soil has been stabilized), then the structure can be lifted with our slab lifting process.

Void Fill

Water erosion beneath slabs can cause voids to form that weaken the structural integrity and allow higher water pressure to develop. Filling these voids with rapidly expanding foam that is designed to react in the presence of water will return the integrity to the structure and prevent trip hazards. We have polyurethane resins designed specifically for this type of application.

Whether you’re a property owner looking for a professional to repair trip hazards on your property, or a contractor looking for material and/or technical assistance – Alchemy-Spetec is at your service.  Give us a call at 404-618-0438 to discuss your trip hazard concerns.
