Thor Helical USA is a supplier at 340 W Passaic St in Rochelle Park, New Jersey. Its website sells helical wall ties, crack stitching bars and related masonry repair products, not helical piles for foundations.
The catalog covers retrofit wall ties, grout ties, strap ties, crack stitching kits and bars, plus grout and mortar. Listed applications include replacing cavity wall ties, tying facades to interior walls, stabilizing bulging walls, repairing brick lintels and pinning masonry arches. The word helical refers to the twisted shape of its stainless steel bars.
This appears to be a mis-categorized listing for a foundation pile directory. Masonry contractors can request a quote or order online through the site, or call 201-880-8819. Homeowners and engineers looking for helical pile installers should use other listings in the directory instead, since this company sells masonry repair hardware for brick and block walls.
