Filling Voids with Polyurethane Foam in Atlanta

There are many areas in which soil voids in and around structures may present a danger to the building and/or the people inhabiting the space.

Voids Caused by Soil Erosion

Sometimes these voids aren’t even noticed until damage has been done to the structure.  For example, a slab sinks after soil beneath it erodes away and forms a void.  Or a crack appears in a wall because the foundation is sinking due to voids in the soil that was once supporting it.  Pool decks can crack and large sections can sink due to voids appearing underneath.  This can cause a dangerous trip hazard for people using the pool.  Rocking slabs in a warehouse or factory floor can also be a sign of voids underneath. In all these cases, safety can be returned to the structures by filling the voids with high-strength polyurethane foam (and then lifting the slab or structure if needed).

Voids Caused by Other Factors

Soil erosion isn’t the only cause of voids that need to be filled with polyurethane. There have been cases in which floors have been in danger of collapsing due to design issues and the safest solution was to fill the crawl space void with polyurethane foam.  Sometimes contracters dig trash pits on new construction sites and fill them with debris left over from the building process.  Later on, the trash in the soil decomposes and voids appear.  Polyurethane void fill can also be an excellent solution for filling/stabilizing abandoned pipes.

Preventative Void Filling Can Save You Money!

You may even want to get your property checked by GCS for voids regardless of any danger signs.  We have advanced soil testing methods for just that purpose.  Filling voids BEFORE any damage occurs can save you a lot of money!

Deep Soil Lift Under Driveway and Garage in Atlanta

GCS recently performed  a deep soil lifting job for a homeowner in the Decatur area.  The homeowner noticed separation between the brick veneer on their garage and the surface of their driveway.  In addition, the garage door was not closing completely due to a settled driveway slab.

The GCS crew performed soil testing which revealed deep soil instability.  The top 20 feet or so of the soil beneath the garage and driveway turned out to be unstable.  This particular problem called for the Deep Lift process.  We used Alchemy-Spetec’s Deep Lift 420 to lift and compact the soil, which also leveled the slab above.

The whole procedure was performed in half a day.  The garage and driveway were immediately ready for use and the garage door was working normally again.

The GCS Advantage Part 3: Ground Penetrating Radar & Soil Testing

In this 3 part blog series, we’re taking a look at the 3 advantages to doing business with GCS vs. common alternatives you may find in the market.

These 3 advantages are:

  1. Using polyurethane vs cement.
  2. GCS best practices.
  3. Ground penetrating radar & soil testing.

In this 3rd post of the series, we’ll take a brief look at why our use of ground penetrating radar and soil testing provides you with a distinct advantage over the use of a common contracting company.

As we thoroughly explain in our previous blog post Soil Imaging & Testing, the use of ground penetrating radar and soil testing vastly improve the accuracy of the soil stabilization, void fill and slab lifting process. They also add an extra level of assurance for the property owner/manager, because imaging and testing can be done AFTER the repair process to demonstrate the extent of the work that was done underneath the surface. Take a moment to read through that previous post before proceeding. Now consider this…

Why would you use a contractor who can’t provide you with an objectively accurate picture of the problem AND the repair?  Do you want to rely on their guesswork instead?

We hope these last 3 blog posts have helped provide you with good sense of how we can make your repair process as painless and efficient as possible.

The GCS Advantage Part 2: Best Practices

In this 3 part blog series, we’re taking a look at the 3 advantages to doing business with GCS vs. common alternatives you may find in the market.

These 3 advantages are:

  1. Using polyurethane vs cement.
  2. GCS best practices.
  3. Ground penetrating radar & soil testing.

In this 2nd post of the series, we’ll take a brief look at why our best practices provide you with a distinct advantage over the use of a common contracting company.

As we thoroughly explain in our previous blog post OUR Best Practices Benefit YOUR Property, the preparation, slab lifting and wrap up procedures we follow are designed to ensure we provide the highest quality service in the industry. Take a moment to read through that previous post before proceeding. Now consider this…

Why would you use a contractor who can’t provide you in advance with a detailed description of their quality assurance procedures?

In the next post we’ll provide an overview of advantage number 3 – our use of ground penetrating radar a

 

nd soil testing.

The GCS Advantage Part 1: Polyurethane vs Cement

In the next three blog posts, we’ll take a look at the 3 advantages to doing business with GCS vs. common alternatives you may find in the market.

These 3 advantages are:

  1. Using polyurethane vs cement.
  2. GCS best practices.
  3. Ground penetrating radar & soil testing.

In this post, we’ll take a brief look at why our use of polyurethane soil stabilization, void fill and slab lifting resin is advantage for you compared to the alternative of using cement grout for soil repair (a.k.a. “mudjacking”).

As we thoroughly explain in our previous blog post Polyurethane vs. Cement for Slab Jacking, the material we use provides you with a few very significant advantages: the lighter weight of polyurethane prevents further sinking (unlike heavy cement), the polyurethane application process creates less mess, and polyurethane cures a lot faster!

Why use a mudjacking contractor who plans on applying heavy, messy, slow-curing material?

In the next post we’ll provide an overview of advantage number 2 – our best practices!

Stabilizing and Lifting Factory Floor Slabs in the Atlanta Area

Uneven, Sunken or Rocking Slabs

Uneven, sunken or rocking slabs in your factory can cause damage to vehicles/ equipment, trip hazards, worker/customer injury, liability risks, and in the worst cases – fatal accidents. They also indicate the possibility of dangerous voids or even potential sinkholes underneath the slabs. (Skeptical about sinkhole dangers? Watch this security footage of a sinkhole swallowing up cars at the National Corvette Museum.)

Your Options

You have a few options when it comes to dealing with uneven, sunken or rocking factory floor slabs. 1. Do Nothing:
The problem with doing nothing is that the situation will likely get worse the longer you wait.  And the longer you wait, the more expensive the eventual repair. 2. Replace The Slab:
Replacing the slab will likely take several days, cause a lot of down time for your business, create a mess, and very often cost more than a simple repair. 3. Stabilize and Lift with Cement Grout:
This procedure (commonly known as “mudjacking”) requires heavy equipment, large drill holes and the use of weighty cement grout (which may sink over time). 4. Stabilize and Lift with Polyurethane Foam
This procedure uses unobtrusive equipment, light (but high-strength) lifting foam, small drill holes and it is the least messy of all your repair options.

How GCS Can Help

Ground Consolidation Services lifts slabs and stabilizes soil with high-strength light weight polymer foam. The expansion force of the concrete leveling foam coupled with the pressure of a specialized pump generate enough controlled force to lift concrete slabs back into position with 1/8” precision. This can be accomplished at a fraction of the cost and time required for replacement.

Repairing a Sinking Garage Floor in the Atlanta Area

We recently repaired a sinking garage floor in the Atlanta area.  We’re going to break down the job for you in today’s blog post…

Sinking Garage Floor

There was a large void under the home owner’s garage floor.  It was 2 feet deep and 12 feet wide in some spaces.  This dangerous void was discovered when the driveway was torn out for replacement.  The garage floor itself was also sunken 3 inches in the center.

Garage Floor Repair

We repaired these problems by first injecting high strength polyurethane resin through the top of the slab to fill the entire void.  Once the void was filled and stabilized, we were able to lift the sunken slab to within a ¼ inch of its original position. The home owner was able to park their automobile in the garage within 45 minutes after the crew cleaned up and left.  Not only did this rectify a dangerous situation, but it saved them from having to replace the garage floor. The customer was very pleased and happily surprised at how far we could lift the slab. The entire job took about 8 hours.

Atlanta Area Pool Deck Repair

We recently repaired a pool deck in the Atlanta area.  We’re going to break down the job for you in today’s blog post…

Sinking Pool Deck

There was a void underneath and sinking pool deck slabs on the side of the pool opposite the house.  The slabs on the opposite side of the house often sink because soil is often added during pool construction.  The added soil on the side of the house usually doesn’t anywhere due the house wall holding it in place.  If the soil on the other side has no barrier, it can often start to wash out.  This can create voids and stability issues for your pool deck.

Pool Deck Repair

We repaired the problem by first filling the void with high strength polyurethane foam, and then leveling the sunken slabs.  The foam strengthens the soil as it cures, to prevent it from washing out.  In addition to the incredible strength of the foam, its light weight provides an advantage over alternate methods such as “mudjacking” with cementitious grout.  Heavier cement-based grouts will often sink or slide over time.

An additional advantage was the reduction of trip hazards due the leveling of the slabs.  Potential injury and litigation risks due to unlevel slabs were eliminated.

This repair took a maximum of about 6 hours.  The pool deck was ready for use 30 minutes after the crew cleaned up and left.  The customer was happy with the efficient and thorough repair job.

Stabilizing and Lifting Warehouse Slabs in the Atlanta Area

Uneven, Sunken or Rocking Slabs

Uneven, sunken or rocking slabs in your warehouse can cause damage to vehicles/ equipment, trip hazards, worker/customer injury, liability risks, and in the worst cases – fatal accidents. They also indicate the possibility of dangerous voids or even potential sinkholes underneath the slabs. (Skeptical about sinkhole dangers? Watch this security footage of a sinkhole swallowing up cars at the National Corvette Museum.)

The Importance of NSF Approval

The National Sanitation Foundation develops public health standards and certification programs that help protect the world’s food, water, consumer products and environment.

In a lot of cases, it’s very important to make sure the products a contractor uses on your property meets NSF/ANSI 61-5 standards for contact with drinking water. This testing covers all products that are usually used in or around drinking water from source to tap.

It can also be important to have NSF approval on products that don’t come into contact with drinking water, in order to be sure they’re safe for the environment in general.  Having NSF approval on the products your contractor uses can be critical.  When we evaluate a possible repair job on your property, we will take this into account and use NSF approved products when necessary.
