From the manufacturer: “Superior Walls panels are bolted together at the top and the bottom of each panel and a one-part polyurethane sealant is used to seal the panel joints of the foundation system. This one-part polyurethane sealant is specifically manufactured for use with precast concrete products.”
Backfill of the foundation walls and getting ready for rough underfloor plumbing. This was also done by others as my wheeled equipment in this beach sand is not very effective.
Rough plumbing in and ready for inspection. I hired out plumbing. Had to pick battles as I do not have enough time to do everything. I am working full time while building this project.
