Ground Consolidation Services was recently called in to seal off a rain-induced ceiling leak in a new construction high rise penthouse suite in Buckhead. Sealing off the water intrusion from the roof above was not an option, due to the rooftop swimming pool directly above the penthouse. So, we had to get into the ceiling from the interior of the suite and inject from the underside.
We injected Spetec PUR F400, a water-reactive, hydrophobic, flexible, single component polyurethane resin. This product is ideal for sealing off active leaks in cracks. In this case, the leak was shut down in less than two minutes. This all went down literally right before the new tenant was scheduled to begin moving in. (No pressure there!)
We are constantly amazed by the wide variety of scenarios in which we’re able to utilize these products. No two days are the same and they’re definitely never dull!

Recently 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!
