• Case Study: Pool deck repair with Precision Lift®

  Pool deck repair with Precision Lift ®

   

  

  A senior living facility in Tennessee had uneven concrete slabs in its courtyard as a result of settling and tree root growth. The business was originally built in the 1960's and has a courtyard, complete with a swimming pool, surrounding by the building on all four sides. This contributed to drainage issues which allowed for wash-out underneath the slabs.

  The sinking of the concrete panels was drastic. The drop-off was as much as 4.5" in some areas. For any business, this would be a problem needing a quick solution for customer (in this case, residents) safety. Being that this is a retirement home and many use walkers for mobility, the need for a quick resolution was magnified.

  Those that did suggest the 'tear out & replace' method gave quotes in the area of $100,000. Even without factoring in the incredibly expensive price tag, this would be a prolonged repair process and would likely take weeks. 

  Precision Lift from Prime Resins, was able to repair all areas at a fraction of the cost in a much smaller time frame than replacement. Over 1,200 lbs. of Precision Lift 4.0 was used in total on the 50 x 100’ area. All slabs with trip hazards were raised and any voids that were created underneath the slabs were filled. One simple quote from the owner of the property sums it up nicely – “everything turned out much better than I ever expected”.​

   

   

   

• Case Study: Leveling Concrete Panels Around a Pool

  Problem:  A leaking 135’ seawall on the Intracoastal Waterway in Delray Beach, Florida, needed extensive repair to reverse the damage caused by years of erosion. Some of that erosion was under the adjacent pool deck, causing it to begin collapsing in areas. The job involved sealing leaks, extensive void filling, soil stabilization and slab lifting.

   

  

   

  Solution: All the grouting work was completed with just two Prime Resins products:

  • Prime Flex 920 for filling the voids, stabilizing the soil and sealing the leaking seawall
    (This product has been independently tested and verified to meet NSF/ANSI Standard 61 for contact with potable water, an important designation for this job on the Intracoastal Waterway.)
  • Precision Lift 2135 to lift the pool deck slabs back into position

  The construction company owner and his colleague attended two days of training at Prime Resins headquarters in June in preparation for this job, but also engaged Prime Resins’ on-site technical assistance. “Having David Dingler on site was invaluable,” said the foreman. “We learned a lot at the training, but there’s only so much you can absorb. Plus David trained our third guy on the spot who now knows as much as we do. 

  

  Having such a big job for their first grouting experience was a bit of trial by fire, but the contractor is glad it turned out that way. “I wouldn’t have it any other way,” he said. “I’m glad it was a big job. We ran into every snag imaginable, and David was there to help us work through them, so it was a great learning experience. The technical support was the most valuable part of the job. Learning the most important aspects of grouting—void filling, sealing leaks, soil stabilization and slab lifting—all in one job was great.”

   

  

   

   

  Alternative options:
   The homeowner had two other options: excavation and replacement. Quotes for excavation repair of the seawall ran around $150,000, which didn’t even include backfill. Plus half the small backyard would have been destroyed. As for replacement, price wasn’t the only consideration. Given the property’s location on the Intracoastal Waterway, six to eight months of permitting would have been required prior to work beginning. The owner would be looking at a year before he could dock his boat. And the cost? Anywhere from $350,000 – 500,000. The grouting was about two thirds the cost of excavation repair.

   

  Outcome: 
  The grouting was successful on all counts. Ultimately, two properties were saved: the leaks were so extensive that grout migration ended up grouting part of the neighbor’s seawall as well. The contractor will build the owner a 70’ dock with a lift off the seawall for the owner’s yacht. The chemical grouting sufficiently reinforced the wall so that no further strengthening is needed prior to dock construction; a strength test approved the seawall’s ability to support the dock. In some places behind the seawall they injected grout as deep as 12 to 13 feet through probes. The voids beneath the pool deck were filled and the slabs lifted. The lightweight polyurethane foam is the perfect solution in this scenario. Cementitious grouting, i.e. mudjacking, was not possible with the limited access and with the erosion issues. Cement slurry is too heavy for that situation.

   

  What was the biggest challenge?

  “The fact that it was our first grouting job and the scope of everything we had to do. The amount of natural obstacles—trees and shrubbery—was also a challenge. Plus the amount of water rushing under the pool deck was eroding so much soil,” said the contractor.

   

   

  “We are very, very pleased with the support we got from Prime Resins. It was invaluable. You sharing your expertise helps us and helps everybody who uses your products.”
