Deep Lift

Leveling and Stabilizing a Factory Floor

Body - Leveling & Stabilizing a Factory Floor

Recently Ground Consolidation Services was contacted by a South Carolina engineering and contracting firm for some help at an industrial food grade production plant. Due to poor compaction of the soils under the slab, cracking and settlement occurred. This was especially problematic because large injection mold machines sit atop this area and have to be level to work properly. Obviously having machines of this nature not running is quite costly to a production facility.

It was determined that soft unstable soils existed as far as 5 feet below the surface. GCS performed a series of deep soil injections using Alchemy-Spetec's AP Lift 475, a high- strength hydro-insensitive polyurethane foam capable of supporting 14,000 lbs per square foot. The deep soil injection process used in this application is a form of compaction grouting designed to squeeze the loose soils in a confined space. Once the soil was stabilized, we injected directly through the slabs in order to lift them back to their original level position.

The facility engineers and managers were thrilled to get the machines back online, not to mention all this was done by lunchtime! These issues are all too common and unfortunately, a lot of people don’t know that these less invasive, less costly, and less time-consuming repair options are available. The alternative to our method would have been removal and replacement of the concrete. Could you just imagine the time, cost, and mess (especially in a food-grade facility)? If you see signs of concrete settlement, such as cracking or uneven joints, give us a call for a free evaluation!

Garage Floor Depression Leveled in Acworth, GA

Unstable Garage Slabs = Danger

The weight of the average automobile is currently around 4,000 pounds.  When dangerous voids or unstable soil undermine your garage floor slab, you are parking that two ton machine on a surface that could possibly collapse.

Lest you think we're exaggerating, take a look at this 5th anniversary video of the floor collapse at the National Corvette Museum.  The video contains a recording of the 911 emergency call, juxtaposed against security cam footage of the concrete slab collapsing - taking some Corvettes with it.

Polyurethane Slab Repair

A homeowner in Acworth, GA recently noticed that his garage floor was depressed in the middle - bowing down towards the center of the garage.  He wisely called Ground Consolidation Services.  Our crews used Alchemy-Spetec's AP Lift 430 polyurethane foam to stabilize the soil deep beneath the slab and also to lift it back into place.

See the before and after photos: The string was secured at either end of the garage - revealing the 1.75" depression in the middle of the slab before the repair AND the almost non-existent depression after the repair.

Lifting & Stabilizing a House Foundation in Dunwoody, GA

A family in Dunwoody, GA recently began the process of refinishing their basement. The contractor they hired quickly noticed that the corner of the house was sinking into unstable soil. He wisely recommended that they find a deep soil lifting contractor, and they ended up contacting GCS.

When major structural elements are sinking, the repair procedure is different from your standard slab lift process in which high-strength polyurethane foam is injected just beneath the sunken slab. The deep structure lifting procedure consists of injecting high-strength polyurethane foam deep into the soil beneath the structure, solidifying and lifting the substrate - and leveling the structure in the process.

In this case, the GCS crew drove four temporary injection pipes eight feet down into the supporting soil (two injection pipes on each side of the sunken corner). They injected Alchemy-Spetec's AP Lift 430 beneath the foundation and raised it back into place. The owners were glad to be back on track with their basement renovation project.

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. 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...

Soil Stabilization in the Atlanta Area

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.

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.

Lifting Slabs, Stabilizing Soil, Filling Voids & More…

Ground Consolidation Services lifts slabs, stabilizes soil, and fills voids with efficient and durable polyurethane resin. Prior to the soil repair process, GCS uses the Deep Look GPR system to reveal the full extent of sub-surface problems endangering your slab or structure.

Sinking slabs, unstable soil, and underground voids can eventually cause serious injury, costly litigation, and even death. GCS takes these issues very seriously. We, therefore, employ only seasoned experts with decades of experience using the latest in state-of-the-art technology.

Slab Lifting

Sunken slabs or structures create trip hazards, liability risks and are often a sign of further damage to come if the problem is left unaddressed. Fortunately, they can be leveled with high strength polyurethane resin. In optimal conditions, slabs and structures can often be lifted to within 1/8” of their original level. Polyurethane slab lifting is much more efficient and a lot less expensive than demolishing and replacing the slab or structure.

Common structures lifted include:

  • Driveways
  • Patios
  • Garage Floors
  • Pool Decks
  • Stoops
  • Steps

Soil Stabilization

Unstable soil often causes structural cracking, cave-ins, and sinkholes. Fortunately, soil can be stabilized and water infiltration stopped with polyurethane resins. Once the soil has been consolidated and strengthened, any slabs or structures resting on it can be leveled if needed.

Filling Voids & Deep Lifting

Undetected voids are a silent threat that can cause slabs and structures to sink or collapse without warning. Neglect can result in serious injury, litigation and even death. GCS can protect your property and assets from these possibilities with the latest void detection and repair technologies. When required, slabs and structures can be lifted from deep within the soil.

Ground Penetrating Radar & Soil Testing

The Deep Look™ wireless ground penetrating radar system uses a patent pending unique triple frequency antenna design to create the most accurate image possible of the area beneath your valuable structures. Conventional single frequency antenna GPR systems cannot deliver the same level of clarity. Ground Consolidation Services will use the Deep Look GPR to take remove all uncertainty and take the guesswork out of the diagnostic process. A crystal clear understanding of the problem provides the best foundation for accurate, durable and lasting repairs.

GCS also has tools for probing the ground's soil density up to 40 feet deep.  Used separately or in combination with the Deep Look™ GPR system, the soil probing process provides additional valuable information about the conditions of the ground you depend on to support your valuable structures.

Ground Penetrating Radar and Void Fill Underneath a Gymnasium in Georgia

Not too long ago, we were contacted about a slab issue at a gymnasium in a children’s home in north Georgia.  The slab in the center of the gymnasium was unstable and rocking back and forth whenever someone walked on it.

We scanned the soil beneath the slab with the Deep Look Ground Penetrating Radar.  The scans revealed large voids underneath the slab.  To stabilize and level the slab, we used Alchemy-Spetec's AP Lift 430 polyurethane foam.  The whole project only took half a day to complete.

The slab was back in use 30 minutes after the job was done.  The administrators at the children's home, needless to say, were very happy.
