The Dangers of Neglecting Sunken Slabs

The Dangers of Neglecting Sunken SlabsAs a property owner or manager, the last thing you want to do when faced with sinking concrete is to ignore the problem.  At there very least, you should get a ground penetrating radar scan to get a sense of the extent of the soil issues.  In this post, we'll review the dangers of neglecting sunken slabs.

Damage to vehicles/equipment.

Unlevel concrete in driveways, factories and warehouses can cause damage to automobiles, fork lifts and other equipment.  Why risk expensive car and/or equipment repairs when you can take care of the cause instead?  Sometimes you're looking at wear and tear over time.  Sometimes you're looking at sudden damage or an accident.  Either way, neglecting the problem is not worth the risk.

Possibility of catastrophic
sinkholes.

Sinking concrete could be a sign of a sinkhole beneath your slab or structure.  Not convinced?  Watch this incredible security cam footage of a sinkhole taking out an entire showroom floor at the National Corvette Museum.  The truth is, you have NO way of knowing what lurks beneath your valuable slabs and structures until you get a professional to evaluate the situation.

Trip hazards, injury and liability risks.

For a thorough overview of these subjects, see our blog post Concrete Leveling to Prevent Trip Hazards and Litigation Risks...

Concrete 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, death, and/or a lawsuit. Read more...

Ground Consolidation Services: What We Do

GCS on Jun 12, 2019 2:58:55 PM
Ground Consolidation Services: What We Do
Ground Consolidation Services: What We DoGround Consolidation Services lifts slabs, stabilizes soil, and fills voids with efficient and durable high-strength 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.

Concrete Leveling

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.

Stabilizing Soil

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.

Pressure Grouting

Unstable soil is a constant threat to structures and slabs that depend on a solid foundation. Some problems require compaction grouting (solid columns of grout), while other problems require permeation grouting (grout mixed in with the soil). Both types of pressure grouting provide lasting support for your valuable buildings and infrastructure.

Filling Voids

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.

Soil Scanning with Radar

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.

Loading Dock and Ramp Repair for Sinking or Unstable Slabs

Loading Dock and Ramp Repair for Sinking or Unstable Slabs

Loading Dock and Ramp Repair for Sinking or Unstable Slabs

Loading docks and ramps are often the most actively used parts of a warehouse. With heavy equipment and cargo traversing those areas on a regular basis, it's not uncommon to see slab issues. Rocking slabs, cracked slabs and sunken slabs are common signs of soil and support problems. Ground Consolidation Services can detect dangerous voids or unstable soil beneath your loading dock and ramp slabs. Once detected, we can stabilize and/or lift the slabs as needed.

Completely replacing your slabs is an alternative approach but repairing with polyurethane is generally more efficient and requires less downtime. Why make a mess and put your dock or ramp out of service for many days when you can have them ready to use 15 minutes after a quick, surgical repair?

Generally speaking, polyurethane repair works with slabs that are still intact or have a few cracks at most. A completely shattered slab will most likely need to be replaced. If you have questions about your slab, call GCS at 678-337-8374 today!

Stabilizing Showroom Floor Slabs

GCS on Apr 30, 2019 1:41:34 PM

Stabilizing Showroom Floor Slabs

Stabilizing Showroom Floor SlabsDo you own or manage a business with concrete showroom floors? Auto dealers, large wholesale stores, convention centers and other businesses need strong and floor slabs to function properly. Unstable slabs can put merchandise, customers and even ownership at risk.  See our two-part blog series on trip hazards and litigation risk...

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

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

Aside from trip hazards there is the larger danger of complete slab collapse if the voids underneath your floor are large enough. See this security cam footage from the National Corvette Museum for an example in action. Ownership was completely unaware of the large voids that eventually caused this showroom floor to collapse, taking all those Corvettes with it.

Ground Consolidation Services can level and stabilize sunken or rocking slabs, significantly reducing your risk. Even if you aren't noticing any immediate problems, it may be worth getting your slabs tested for dangerous voids lurking beneath.

How Sinking Slabs Damage Structures

GCS on Apr 26, 2019 10:05:01 AM
How Sinking Slabs Damage Structures
How Sinking Slabs Damage StructuresSinking slabs can damage your valuable structure in a number of ways. We'll take a look at five of the most common threats that unstable soil can pose to your building. (It's important to understand that weak soil and dangerous voids beneath your foundation can be detected BEFORE any of this damage occurs. For more on that subject, see our blog post on soil imaging and testing.)
 

1. Warped and/or Broken Floors

 
Unreliable soil beneath a foundation can cause it to shift. Even small shifts can make the floors buckle or even crack. How much would it cost you to replace the floors in your structure?
 

2. Cracked Walls

 
A slipping foundation can also damage sheet-rock or concrete walls. Your walls are not strong enough to keep the foundation from moving. It's the other way around, unfortunately.
 

3. Stuck or Scraping Doors

 
Your door frames are also at risk. The minute the wall or floor starts to shift, the door frames can warp and make the doors difficult or even impossible to open and close.
 

4. Dislodged Molding

 
Perfectly installed moldings really add character to a room. Once they start getting dislodged and sticking out here and there, however, they can become a black eye (and a sign of deeper foundation issues that could have been prevented).
 

5. Unstable Trees, Flagpoles, Lamp Posts, etc.

 
If you have any large trees, flag poles or lamp posts that could hit your house if they fell down, you have one more reason to get your soil tested. Unreliable soil can undermine these objects as well.
 

It May Not Be Too Late

 
The good news is that, even if you are already seeing some of these types of damage on your property, GCS may still be able to repair your soil and level your slab or structure with high strength polyurethane foam.

Commercial, Industrial & Warehouse Concrete Floor Leveling

Commercial, Industrial & Warehouse Concrete Floor Leveling (3)

GCS Commercial-Industrial Slab Lifting

We spelled it out very clearly in our recent blog post Stabilizing and Lifting Factory Floor 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.)"

If you didn't watch that sinkhole footage the first time we posted the link, watch it now! Ignorance about the state of the soil underneath your slabs can be extremely costly.

GCS Warehouse Slab Repair

Rocking warehouse slabs can damage forklifts, which puts merchandise and even your employees at risk.  They are also a sign that dangerous voids may exist.  Sometimes rocking is caused by slabs curing incorrectly (a.k.a. "curling slabs"). We can fix that too. Read more about our solutions for rocking warehouse slabs.

Expose Hidden Soil Dangers with  Imaging and Testing

A couple of things that set us apart from other slab lifting contractors (aside from our highly skilled technicians and the top shelf lifting resin we use) are the soil imaging and testing services we offer. Why settle for guesswork about what's going on underneath your slab or structure when we can verify the facts for you before we do any lifting work? Read more about our soil imaging and testing services.

Permanent & Durable Slab Repair with Polyurethane Foam

When light-weight material is being installed beneath your slab, you need the confidence that it is strong enough for the application. How strong is strong enough? This is a commonly asked question by property owners or managers that are new to slab jacking with polyurethane. The structural foams we use only need to be as strong as dirt, but they're actually stronger than crystalline bedrock. Read more about the strength of the foam we use.

Eliminate Pool Deck Trip Hazards Before the Summer

GCS on Apr 22, 2019 2:09:34 PM

Copy of Eliminate Pool Deck Trip Hazards Before the Summer (1)

Eliminate Pool Deck Trip Hazards Before the Summer Summer is fast approaching. If you have a pool on your property (or if you manage a public pool), it won't be long until people are walking all over your pool deck. 

There are a couple very common causes for the soil washout that creates the environment for a sinking pool deck slab:

  1. Cracks in the pool structure leaking water into and soil and washing it out.

  2. Loose back-fill on sloping properties.

The first cause is pretty self explanatory.  The second cause may need a little elaboration. Basically, if a pool is built on sloping property, the construction team will back-fill soil onto the side of the pool that needs it. If this soil is not compacted properly, it can start to washout over time.

Regardless of the cause, soil washout removes support from the pool deck slab and creates the condition for sinking.

As we explained in this two-part blog series...

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

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

...tripping hazards can be extremely costly, both from a legal perspective and more importantly from the perspective of basic human safety.

Ground Consolidation Services can test your pool deck for underlying soil washout (even before your slab sinks), fill the voids and lift the slabs if needed.

After your soil is repaired, you will want to get any cracks sealed that may be leaking water into soil and washing it out in order to prevent future trip hazards.

Excessive Rain Creates Dangerous Voids Under Slabs & Structures

GCS on Apr 19, 2019 4:38:06 PM

Excessive Rain Creates Dangerous Voids Under Slabs & Structures

Excessive Rain Creates Dangerous Voids Under Slabs & StructuresThe Atlanta area, where GCS is headquartered, has seen record rainfall in the last 6 months.  Excessive rain can often lead to soil washout underneath slabs and structures.  The voids created by soil washout can lead to sinking or, in some cases, dangerous collapse of the slab or even the structure itself.

Properties with healthy and adequate drainage systems (French drains, catch basins, etc) are the least likely to be affected by heavy rainfall.  However, clogged drainage systems, improperly designed systems, or in the worst case - properties with NO drainage system, all pose a significant risk during periods of excessive rain.  If you have any doubts about your drainage system, contact GCS at 678-337-8374 and ask about our soil testing & imaging offerings so we can look for dangerous voids.

If we find significant voids, we can fill them with high strength hydrophobic polyurethane foam.  Hydrophobic foam pushes water out of the void and cures into place with a density similar to crystalline bedrock.  We can also use polyurethane foam to lift your slab or structure back into place if it has already begun to sink.

If your soil problems are caused by faulty or non-existent drainage, you will still have to correct that issue to prevent future instances of soil washout in other areas on your property.  But the areas we repair should be fine, as the cured polyurethane we use is extremely durable is not eroded by rainwater.
