Polyurethane Lifting vs Mudjacking

Polyurethane Lifting vs Mudjacking

Polyurethane Lifting vs MudjackingIf you have a sunken slab on your property, you have a few options:

  1. Do nothing. If you choose this option, the problem will likely grow. And the longer you wait, the more expensive the repair.

  2. Replace the slab. The process will take a minimum of several days, is often messy, and is typically more expensive than repair.

  3. Lift the slab with cement grout. This procedure (known as "mudjacking”) requires heavy equipment, large drill holes and the use of weighty cement grout which may sink over time.

  4. Lift with high-strength polyurethane foam. This procedure uses light equipment and material, small drill holes and makes less of a mess.

So as far as repair choices go, you are looking at polyurethane lifting vs mudjacking.  Here at GCS, we use industry leading AP Lift Foam for a durable and lasting repair.  Here's an overview of the differences between AP Lift Foam and the cement grout used in mudjacking:

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.

Concrete Stabilization and Leveling on School/University Properties

GCS on Oct 8, 2019 10:00:00 AM

Concrete Stabilization and Leveling on School_University Properties

Concrete Stabilization and Leveling on School_University PropertiesWatch this recent video from a Brazilian news site.  Luckily, no one was seriously injured when a school floor collapsed beneath a room full of students.

The students and school administrators were lucky in this case, since everyone escaped unscathed for the most part.  Will you be as lucky if a similar incident occurs on your property?

On the "not-quite-so-urgent" front, we were recently contacted by a school in a nice Atlanta suburb. They were having issues with trip hazards on walkways throughout their campus due to sunken slabs. This issue still made the school vulnerable to lawsuits.

We used high-strength polyurethane foam to level all of these dangerous liability/injury risks.  It took us about two days to repair all the trip hazards on campus.

Do you have any similar issues on your property? Contact us at 678-337-8374 for a free repair estimate today!

Filling Voids Under Slabs with Polyurethane

GCS on Oct 1, 2019 4:00:07 PM

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.

Concrete Lifting to Prevent Trip Hazards in Neighborhood Pools

GCS on Sep 25, 2019 11:10:29 AM

Concrete Lifting to Prevent Trip Hazards in Neighborhood Pools

Concrete Lifting to Prevent Trip Hazards in Neighborhood PoolsIf you own or operate a neighborhood pool, it is critical that you understand the risks associated with sunken pool deck slabs.

This past Spring, we published the blog article Eliminate Pool Deck Trip Hazards Before the Summer containing the following essential info on this issue...

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.

Seawall Repair on Lake Oconee and Robin Lake

GCS on Sep 20, 2019 10:28:26 AM

Seawall Repair on Lake Oconee and Robin Lake

Seawall Repair on Lake Oconee and Robin Lake

Lake Oconee and Robin Lake at Callaway Gardens are two of the most significant bodies of water in close proximity to the greater Atlanta area. Do you own or manage property on either of these lakes? If you have a seawall on your property, you may want to check for the following:

  • Settled soil near the wall (a sign of water leaking through the wall and eroding the soil on the land side).
  • Soil deposits near the seams on the water side of the wall (a sign of water leaks bringing soil through the seams into the lake).
  • Visible rust colored cracks or stains in the wall (a sign of water leaking through cracks in the wall and rusting the rebar inside).

These could all be indications that your seawall is leaking and in need of repair.  Polyurethane seawall repair is less expensive and more efficient than tearing out the wall and replacing it completely.

At GCS we use Alchemy-Spetec’s AP Fill 700 high-strength polyurethane foam on our seawall repair jobs.

Proven Strength

Impermeable to water once in place, this foam decreases the likelihood of future erosion versus refilling the void with soil or other material.

Originally developed over 30 years ago, and continuously improved since, this technology has one of the longest histories of success in the field among repair uses of polyurethane foams.

Environmentally Safe

AP Fill 700 has been approved for contact with drinking water (NSF 61-5) by Truesdail Laboratories. While no one will likely be drinking out of the lake water, this extra level of precaution means that the cured resin has no adverse effect on water quality.

Efficient Installation

Results are immediately clear due to the visible exiting of water when the foam is injected.  The foam rapidly sets in less than 10 minutes.  No heavy equipment is needed, as the foam is simply injected through pipes directly into voids and loose soil using a small single component pump.
