Leak Seal and Void Fill of Detention Pond Pipes in Duluth, GA

Leak Seal and Void Fill of Detention Pond Pipes in Duluth, GARecently we got a call from the President of a home owners association in Duluth, GA.  The bottom of a large culvert pipe in a detention pond had decayed to the point that it was leaking massive amounts of water into the surrounding soil.  A critically important standpipe was then threatened by a soil void caused by this water leak.

Ground Consolidation Services injected Alchemy-Spetec's AP Lift 430 high strength polyurethane foam through the bottom of the pipe (see photo included with this article) to form a leak seal barrier and return the culvert to its full functionality.  We then injected the foam into the void around the standpipe.  Filling this void and compacting the surrounding soil created a solid impermeable mass that will support the standpipe for years to come.

This waterway leads to the Chattahoochee river, so we made sure to use a foam that was NSF approved for contact with drinking water.  Environmental safety is a top priority for GCS.

The home owners association President was thrilled that this repair was accomplished without large machinery and/or the full replacement of the pipes.  GCS saved them lots of time and money!

Garage Floor Depression Leveled in Acworth, GA

Garage Floor Depression Leveled in Acworth, GAUnstable 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.

Leveling Sunken Driveway Slabs in Atlanta

Leveling Sunken Driveway Slabs in AtlantaIn most cases, sunken concrete driveway slabs should be repaired the moment you notice them. Settled concrete creates trip hazards for you and your family.  Sunken driveway concrete can damage your valuable vehicles.

Any time you notice these issues on your property, it's important to consider the possibility that deeper soil issues exist.  Sometimes settled concrete is a sign of dangerous voids underneath the slab.  In rare cases, a slab can cave in or completely collapse.

Ground Consolidation Services can perform extensive soil testing to determine the condition of the soil beneath your valuable structures.  When problems are found, we can fill dangerous voids, stabilize soil, and level slabs as needed with high-strength polyurethane foam.

Repairing Sunken Slabs in Convenience Store Parking Lots

Repairing Sunken Slabs in Convenience Store Parking LotsSunken Slabs Pose a Threat

Sunken slabs in convenience store parking lots create the dual risk of damage to vehicles and injury to pedestrians. The last thing any convenience store owner wants is litigation due to neglect of a dangerous situation.

GCS Can Eliminate This Risk

Fortunately, if your parking lot is concrete (as opposed to asphalt), GCS can very likely eliminate these hazards quickly and efficiently. Concrete leveling with high-strength polyurethane foam is a fast, precise procedure that requires less downtime and less mess than the alternative repair methods of mudjacking or slab replacement. "Mudjacking" with cement grout requires heavy equipment and creates quite a mess compared to efficient polyurethane foam injection. Ripping out and replacing the concrete requires heavy equipment and lots of downtime.

Filling Voids Under Slabs with Polyurethane

Filling Voids Under Slabs with PolyurethaneSilent Threat

Voids underneath slabs are a silent threat.  As you can see in the photo included with this blog post, soil can erode underneath a slab to the point where significant gaps occur.  If the void is visible, like the one in the picture, property owners and managers will become aware of it pretty quickly.  If the void happens to be at the center of the slab, or underneath an inside slab, it may not be so easy to notice. 

Void Detection

Ground Consolidation Services offers void detection with the Deep Look ground penetrating radar system.  We can provide images of the area beneath your slabs to 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 and lasting repairs.

Void Repair

Dangerous voids can be filled with high-strength polyurethane foam (and then the slab can be lifted if needed).  Ground Consolidation Services lifts slabs, stabilizes soil, and fills voids with the most efficient and durable polyurethane on the market.

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.

Concrete Leveling

Sunken structures create trip hazards, liability risks and are often a sign of further damage to come. But 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.

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.
