Carolina Foundation Solutions, LCC completed a highway widening project over I-85 South near Blacksburg, SC installing a series of temporary shoring walls at exits 100, 102 and 104. Approximately 80 soil screws were installed at exit 100, 100 soil screws were installed at exit 102 and 70 soil screws were installed at exit 104. The general contractor made 5 ft cuts along the
length of the shored area (the lift) and soils screws were installed every 5 ft.
by Carolina Foundation Solutions.
The wall was then covered with a welded wire fabric and 4 inches of shotcrete.

Carolina Foundation Solutions, LLC installed the InvisiBeam System by InvisiBeam System that included the installation of 7 carbon fiber reinforcement straps along a basement wall in a residence in Winston Salem, NC. The basement wall was bowing and showing horizontal cracking due to hydrostatic pressure from soils outside of the wall. The Invisibeam System is ICC approved and includes a top anchor that is bolted to the rim joist, a carbon fiber strap that is mechanically bonded to the wall using epoxy rivet technology and has a minimum tensile strength of 234,700 psi, and a bottom anchor that is secured into the basement floor. The Invisibeam system provides a permanent solution and prevents any further movement and settlement in the wall.

Carolina Foundation Solutions installed deep foundation systems as part of the construction of a townhome community in Raleigh, NC. CFS installed 162 helical piles and drilled 23 micro-piles, which were the perfect solution for this site that required deep foundations due to poor soil conditions. The installed piles will be integrated into the grade beam and column footings for 3 new buildings.

A stretch of newly constructed highway was showing signs of settlement due to poor subgrade conditions. CFS injected polyurethane foam into the uncompacted fill and stiffened the soil to provide support to the asphalt roadway above. First 5/8” holes were drilled into the asphalt then pipe was driven down into the subgrade approximately 3-9 ft below grade. CFS injected a predetermined amount of AP440 foam into the fill dirt at the base depth and then lifted the pipe in 3 ft increments and injected additional foam. The roadway was monitored during the injection process with lasers for any lift of the asphalt. Lastly, the pipe from the injection hole was removed and asphalt was patched by others. CFS injected approximately 4,000 lbs of polyurethane foam. This proved to be a significant cost savings compared to the option of removing the existing asphalt and uncompacted material and replacing
with new, compacted structural fill.
