Debunking Myths About Lifting Slabs With Foam

Body - Debunking Myths About Lifting Slabs with FoamWhen parts of a concrete surface sink due to erosion and poor compaction, the resulting trip hazard can be dangerous. If left unrepaired, liability and safety issues linger. Although concrete is tough and durable, unstable soil can cause it to crack and sink. Fortunately, a reliable solution for lifting concrete has been developed and proven over the past few decades. High-strength expansive polyurethane foam is injected underneath the slab to bring it back to level. This method has been used in a wide variety of commercial and residential applications with long-lasting results.

Despite consistently reliable results, some myths about polyurethane slab lifting have cropped up over the years.

Myth #1: Polyurethane Foam is a Temporary Fix

People who assume that polyurethane slab lifting is a temporary fix typically have a general lack of knowledge, understanding, and experience with the process. Common misperceptions supporting this myth include:

  • The incorrect assumption that foam will be susceptible to moisture and degrade under the concrete.
  • The incorrect assumption that the process typically leaves large voids underneath the slab, leading to resettlement.

Water does not cause lifting foams to degrade underneath the slab. In addition, a factory-trained contractor will not leave gaps underneath the slab that would lead to resettlement.

Myth #2: Polyurethane Foam Cannot Support Heavy Loads

Another common misconception is that polyurethane foam is weak and does not have the load-bearing capacity to support slabs with heavy traffic or large structures.

Common misperceptions supporting this myth include:

  • The incorrect assumption that lifting foam is the same stuff used by the insulation guys.
  • The incorrect assumption that because it expands easily, it must collapse easily.
  • The incorrect assumption that the expansion rate is uncontrollable and leads to unpredictable results.

All lifting and stabilization polyurethane foams formulated and manufactured by Alchemy-Spetec are designed specifically for Geotechnical applications. Once cured, Alchemy-Spetec lifting foams are incredibly strong and durable. Easy expansion does not equal easy collapse. Factory-trained contractors can control the final lift level of a slab to within 1/8th of an inch.

Myth #3: Polyurethane Foam is too Expensive

When faced with the dilemma of a sunken slab, you have three options aside from polyurethane slab lifting:

  1. Doing Nothing: If you do nothing, the problem will grow. The longer you wait, the more expensive the repair.
  2. Replacing the Slab: This process will take several days, is often messy, and is typically more expensive than lifting with polyurethane.
  3. Lifting with Cement Grout: This procedure (known as “mudjacking”) requires heavy equipment, large drill holes, and the use of weighty cement grout which often sinks over time. When the cement grout sinks over time, you have to get it lifted again. Eventually, even this process becomes more expensive.

Atlanta Contractors Lift It Rite Featured in Spray Foam Magazine

Banner - Lift It Rite Featured in Spray Foam Magazine

Body - Lift It Rite Featured in Spray Foam MagazineAlchemy-Spetec customers Matt Chittick and Travis Germick of Lift It Rite LLC were recently featured in a Spray Foam Magazine article. SprayFoam Magazine is an industry-leading publication in the spray foam insulation sector. Because so many spray foam insulation professionals are adding slab lifting to their service offerings, the magazine is now covering this technology as well. The article featuring Lift It Rite is a profile of a sidewalk lifting job that was done in order to save an old tree in Winder, Georgia. The roots were disrupting the pavement. Here's an excerpt from the article...

Cities often hire a third party to take care of sidewalks, potholes, and wastewater management issues and it was this third party who contacted Travis Germick and Matt Chittick. They are the owners of Lift it Right LLC, and they were asked if they could help save Winder’s sidewalks.

Germick and Chittick went to Winder to review the situation and noted that several of the sidewalks around the town were obviously sunken. One of them was next to a very old tree and the roots were impacting the sidewalk. This had happened to another tree in the area, and the town took out the concrete and cut some of the roots of the tree. Once a tree’s roots are cut the tree will eventually die so they cut down the entire tree. After the tree was cut down, the residents of the town clubbed together and had a memorial for the tree. After that unhappiness, cutting down more trees in the future was not an option. There had to be another solution to save the additional old tree. Read more at SprayFoam.com!

Banner - Effective Water Treatment Facility Repairs

Body - Effective Water Treatment Facility RepairsThis post is part of the Alchemy-Spetec Contractor Lens series, featuring views, news & case studies written by our customers.  This article, written by Morgan Helms of Helms Polyfoam, is an overview of void filling with polyurethane foam.  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!

Water and wastewater treatment facilities are essential for communities and municipalities. They supply drinking water to communities and treat wastewater before it is discharged into lakes or rivers. Many water and wastewater treatment facilities are aging and badly in need of repairs and maintenance.

Concrete is one of the most common building materials for water treatment facilities. Whether part of new construction or an older structure, concrete can be susceptible to leaks. Leaks through concrete are generally going to be through cracks, joints, and honeycomb (areas in poured concrete of mainly coarse aggregate with voids in between). Depending on water volume and pressure, and the size of the joint or crack, you may encounter weeping leaks, steady leaks, and gushing leaks.

What’s the solution? Helms Polyfoam! With any aging concrete structure in which moisture is present, the need for maintenance is inevitable. When it comes down to dollars spent on water treatment, maintaining water leaks is paramount. Helms Polyfoam can repair and effectively seal leaks in water treatment facilities also while staying within budget.

The Alchemy-Spetec polyurethane leak seal resins we use are pumped into cracks in walls and water holding tanks to fill and seal them, both now and in the future. Anywhere water can go, these polyurethane resins can follow. Polyurethane crack injection repairs and prevents leaks by filling cracks in concrete tanks and pipes. Polyurethane concrete crack injection repair is waterproof and non-toxic. There is no need to worry about dangerous chemicals seeping into the ground or contaminating the water.

Helms is your Mississippi area expert on all structural, polyurethane resin repairs. Our repairs can be completed quickly without shutting down operations or taking anything offline for long periods. Plus, our repairs are much more affordable than other alternatives, such as replacing pipes or tanks altogether.

We implement a repair plan that doesn’t require you to shut down operations or leave you with a big mess. It requires no excavation. This means a smaller footprint on your job site or facility and minimum downtime.

And you know what is even better? ARPA!

The American Rescue Plan Act (ARPA) includes in the Fiscal Recovery Funds (FRF) one of the largest fiscal advances to state and local government budgets in recent history. ARPA federal funding now makes it possible to address infrastructure and structural repairs – just like these water and wastewater treatment facility repairs – that are an ongoing challenge in our state.

Helms Polyfoam has water treatment facility repair experience using polyurethane concrete crack injections to seal off leaks. And now, you can use ARPA funds to help you cover these costs! Call us at 601-966-7821 or click here to fill out our contact form.

Lift Sunken Slabs & Stabilize Loose Soil Caused by Uncontrolled Water

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.

Classic Sewer Failure (Guidance from the Grout Geek)

Posted by Charlie Lerman on May 24, 2022 10:00:00 AM

Banner - Classic Sewer Failure

Body - Classic Sewer FailureRead through this list:

  • Manholes
  • Catch basins
  • Drop inlets
  • Wet wells
  • The Grand Canyon

This is not a game of which one doesn't belong, as they all channel water and can cause erosion. The Grand Canyon is breathtaking. Likewise, washouts or sinkholes caused by leaking and neglected infrastructure are breathtaking - but in a completely different way. They're breathtaking in regard to the high costs of emergency repairs and the potential damage they cause.

This quote, from an article on KCCI.com, sums it up nicely...

“At first, crews resurfacing the pavement thought a large piece of machinery had fallen into a sinkhole 10 feet deep… It turns out an original clay storm sewer pipe had disconnected, leaking water for what appears to be a long time, eroding the earth around it.”

There is no downside to fixing these common infrastructure issues before they get out of control. Any repair costs are quickly offset by the reduction of sewer water requiring treatment. Who is not for lower sewer rates, a healthier environment, longer-lasting infrastructure, and fewer manmade washouts/sinkholes?

So why don’t we address infiltration more? It is as simple as the old adage "out of sight out of mind". Infiltration is a preventable and treatable sewage collection system problem. We have neglected our infrastructure for too long and we need to raise public awareness of the issue.

We at Alchemy-Spetec not only manufacture quality polyurethane chemical grouts for these types of repairs, but we also provide top-notch training and support for leak seal crews. Call 404-618-0438 and let us know how we can assist you in raising awareness about or repairing infiltration. We are all in this together.
