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.

Voids beneath warehouse floors can be filled with AP Lift 475 foam. This product is great for slabs that rock and warehouse floors that have begun to sink. The video below shows an example of the product in action. Inside this warehouse, the floors have begun to rock and are unleveled - which can speed up wear and tear on valuable equipment. With this powerful polymer and its painless application procedures, unlevel slabs can be repaired at a rapid pace. Take a look for yourself!

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…

Lifting

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.

Concrete Leveling to Prevent Trip Hazards & Litigation Risks - Part 1

Posted by Andy Powell on Mar 20, 2019 10:00:00 AM

Concrete Leveling to Prevent Trip Hazards & Litigation Risks - Part 1

Concrete Leveling to Prevent Trip Hazards & Litigation Risks - Part 1Concrete slabs sink for a variety of reasons.  The result is an eyesore and possibly a trip hazard that could - in a worst case scenario - result in a serious injury, a law suit and/or death.  Lifting slabs with polyurethane foam is safe, fast, and economical. 

Property owners and managers should learn how to deal with these liability issues NOW with the latest concrete repair techniques and preventative measures. If you’re a contractor, you need this information because it’s critical for YOUR customer – the property owner.

Common Danger Zones

Since an ounce of prevention is worth a pound of cure, it’s helpful to know where to look for potential sunken slabs, especially if you own or manage a large variety of properties.  As a contractor you’ll want to focus on these types of sites when looking for potential customers.  The three main property categories that tend to have slab settling issues are:

  • Residential (single and multi-family).
  • Commercial and industrial.
  • Warehouse and logistical.

Residential sites can often have driveway, sidewalk, patio, or garage floor issues.  Commercial and industrial sites often contain showroom or factory floors made of concrete slab.  Warehouse and logistical centers can contain huge floors with massive square footage.  Because warehouse floors are often raised off the ground to incorporate a loading dock, they are particularly vulnerable to the formation of dangerous voids underneath.

Causes of Slab Settlement

Let’s take a look at why slabs sink in the first place. There are at least six main reasons:

  • Equipment on surface putting too much weight on slabs.
  • Erosion due to natural causes.
  • Leaking drain pipes and water mains.
  • Improper site drainage or poor water management from downspouts and gutters.
  • Poor soil consolidation/compaction.
  • Old trash pits from the original construction phase that were too close to the structure.

Familiarity with these common causes of slab settling can help a lot when attempting to diagnose the exact cause at a specific location.  For more, see our blog post series The Causes of Unstable Soil.

Results of Neglect

After becoming aware of a slab issue, the property owner has a critical choice to make.  To repair or not to repair – that is the question.  Neglecting a repair can have huge implications.  Here are a few possible results of neglect:

  • Damage to vehicles and equipment.
  • Unlevel racking and storage.
  • Personal property damage.
  • Sinkholes.
  • Trip hazards.
  • Employee injuries.
  • Limitless liability issues.

Read that list a few times and seriously consider the very real possibility that one or more of these events may occur when a property owner neglects a slab repair.  As experts with many years in the industry, we’ve seen every one of these events unfold after a problem was ignored.

In the next installment of this two-part series, we’ll review the two most common methods for repairing a trip hazard aside from polyurethane, and then we’ll review the three most common types of slab repair with polyurethane: slab lifting, soil stabilization and void fill.
