32-Person Hot Tub Gets Lift

32-Person Hot Tub Gets Lift

A New Mexico mountain resort recently unveiled their new fitness complex which featured a large indoor swimming pool and 32 person spa. Built on the side of a mountain, on side of the spa structure sits on top of approximately 12.0’ of fill material. When the spa and portions of the deck began to show telltale signs of settlement, the spa was drained and taken out of service, and an investigation was conducted. This investigation revealed a large plumbing leak which had occurred under the pool/spa deck, causing compaction and consolidation of the supporting fill materials. The general contractor on the job broke out a section of the pool deck to make the plumbing repair, and then turned to URETEK ICR for the remediation of the settlement issues.

Management was pleased that the process meant no disruption for their guests. URETEK’s solution was less than 20% of the cost of replacement of the structure.
