Commercial Slab Repair Overview

Commercial Slab Repair Overview

"Are sinking slabs or structures putting your commercial property at risk? Unlevel concrete parking lots, walkways, showroom floors, factory floors, warehouses, loading docks and more can adversely affect your property value and increase the chance of injury and costly litigation."

- From our blog post Concrete Leveling for Commercial Properties.

GCS uses the Deep Look GPR system to reveal the full extent of soil issues causing your slab or structure to sink.
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.

Repair Your Concrete to Prepare Your Home for SaleProtecting Your Property Value

One effective way to increase the value of your home, and increase the speed at which it sells, is to make some simple soil and concrete repairs.  Sinking driveways, pool decks, garage floors, front steps and foundations can be an eye sore and a safety risk.  When preparing your home for sale, it's important to make sure all of these areas have been inspected and repaired if necessary.

Soil Inspection

Groud Consolidation Services uses a wireless ground penetrating radar system to create accurate images of the area beneath your concrete structures.  This process removes 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.

How Constant Rainfall Undermines Concrete Structures

How Constant Rainfall Undermines Concrete Structures

How Constant Rainfall Undermines Concrete StructuresRainwater & Erosion

Simply put, rainfall causes erosion. Erosion occurs when rainwater removes soil or rock from a certain location and transports it to another location. Erosion ultimately destabilizes soil and in extreme cases can lead to landslides and sinkholes. Rainwater erosion can also cause smaller scale issues such as sinking slabs, voids underneath your structure, or unstable soil that may at some point become a problem.

Repairing Eroded Soil

After investing money in the construction or purchase of a building, the last thing you want is for erosion to put your investment at risk. GCS can fill voids, consolidate soil and halt water migration by permeating the soil with the highly effective Alchemy-Spetec polymer resins we use. Once the bearing capacity of the soil has been increased with this process, then the structure can be lifted if necessary.

Concrete Leveling with Polyurethane

Concrete Leveling with PolyurethanePolyurethane Concrete Leveling

As we state in our blog post Polyurethane Slab Lifting Explained...

Sunken concrete slabs can be lifted back into place with two-component polyurethane foams designed to work in wet or dry conditions. The expansion force of the concrete leveling foam coupled with the pressure of a specialized pump generate enough controlled force to lift virtually any structure back into position with 1/8” precision. Read more and watch a detailed animation explaining the process.

View footage of this process in action on an actual job in our blog post Slab Lifting Time Lapse.

Advantages Over Alternatives

Concrete leveling with polyurethane holds the following advantages over alternative options (such as leveling with cement slurry or replacing the slab)...

  • Lightweight, High-Strength Material
  • Cost Efficient Application
  • Rapid Delivery 

Read an in-depth analysis of your options and these advantages in our blog post Why Polyurethane Slab Lifting Is the Better Choice.

Concrete Slab Repair in Apartment Complexes

GCS on Aug 14, 2019 9:15:30 AM

Concrete Slab Repair in Apartment Complexes

Concrete Slab Repair in Apartment ComplexesSunken or unstable slabs are a threat to all types of apartment properties, from small multi-family units in quiet neighborhoods to busy high rise complexes.  If you own or manage an apartment complex with concrete slab issues, it's important to understand the advantages of lifting with polyurethane vs ripping out and replacing the slab.

The following points are excerpted from our blog post Four Advantages of Lifting vs Replacement...

1. No Excavation

Unlike the disruptive process of tearing out and replacing a slab, polyurethane slab lifting does not require excavation.  No one will have to dig up your drive way and get dirt all over your yard.  Instead, a friendly and professional GCS crew will inject the resin through your existing slab using holes half the size of a dime.  The concrete will be leveled and the small holes will be plugged with either a non-shrink cement grout, durable epoxy or a high strength polymer cement.

2. Clean & Environmentally Friendly

The main lifting foams we use, Alchemy-Spetec's AP Lift 430 and AP Lift 475, are NSF certified safe for contact with drinking water after they cure.  With that high level of safety certification, you don't have to worry about the long term environmental impact.  Meanwhile, what happens to torn out concrete?  Very often, it ends up in landfills.

3. No Heavy Equipment Required

Slab lifting crews are like a small SWAT team: focused, efficient and precise.  There will be no need for heavy equipment on the job, tearing up your yard or making loud noises that disturb your family and/or your neighbors.  Instead, you would have a small truck parked near the slab and a small crew running hoses out of the truck to the slab surface where they are pumping the foam. 

4. No Permitting Required in Most Cases

One last thing to keep in mind: new construction often requires permitting.  Don't want to spend hours down at your local permitting office dealing with the bureaucracy?  You most likely won't have to if you just have the slab lifted instead.

Lifting Concrete Parking Lot Slabs

GCS on Aug 9, 2019 1:59:30 PM

Lifting Concrete Parking Lot Slabs

Lifting Concrete Parking Lot SlabsConcrete parking lot slabs at convenience stores, gas stations, office parks, shopping malls, apartment complexes, schools, factories, and the ground floors of multi-level parking decks are all vulnerable to settling issues. 

If you own or manage properties with concrete parking lot slabs, you would be wise to get the soil beneath those slabs tested on a regular basis.  Ground penetrating radar and other methods can reveal dangerous voids before any problems occur. 

If any of the slabs on your property have already started sinking, make sure you understand the trip hazards and litigation risks you now face.  Injuries to customers, employees, and others from trip and fall accidents are much more likely with sunken slabs in your parking lot.  In addition, there is also the risk of vehicle damage.

Ground Consolidation Services offers free repair estimates for sunken slabs and a soil testing and imaging service for preventative measures.  Call 678-337-8374 to talk to a specialist today.

Leveling and Stabilizing Pool Deck Slabs in the Atlanta Area

GCS on Jul 31, 2019 5:12:59 PM

Leveling and Stabilizing Pool Deck Slabs in the Atlanta Area

Leveling and Stabilizing Pool Deck Slabs in the Atlanta AreaWe posted a blog article this past Spring titled Eliminate Pool Deck Trip Hazards Before the Summer.  In case you missed it, here's an excerpt...

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.

In our blog post Atlanta Area Pool Deck Repair, we describe the GCS pool deck repair process from an actual job...

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.
