After CrossFit Mania, a Repair or Full Replacement?

The Problem



I was commissioned by an insurance company to determine if a gym floor was able to be repaired and refinished or if the entire floor required replacement. The claim was a "subrogation" issue, which is when a claimant's insurance company contacts another insurance company for reimbursement. Most often http://hometime.com/Howto/projects/flooring/floor_6.htm in subrogation claims, the purpose of the inspection is to confirm cause and determine extent of the damage, as the reason for the damage is not always in dispute.

What Happened

This case involved a wood basketball court of 214-inch maple strip nailed to a wood substrate. It was located in a school gym that had been rented out for a CrossFit competition. Mats had been placed over the floor where the weightlifting competition was held. The weights were lifted overhead and often dropped on the floor, breaking boards. The school system had replacement coverage, but the renters had a repair policy. I was asked to address whether there was enough wood left to resand the entire floor if the broken boards were replaced. The floor was approximately 40 years old and, according to building maintenance staff, had been refinished, although they were unsure how many times.

The Inspection

The cause of the problem wasn't in disputethe flooring clearly had damage from the impact of the competition weights. The flooring had open areas at the time of the inspection, so both overall thickness of the flooring as well as the remaining wear layer (over the top of the tongue) could be easily measured. I found there was a full inch of wood left in the wear layer. On inspection of the perimeter of the room, I found old finish under the bleachers. The change was abrupt and consistent with sander marks, indicating the bleachers were not removed for refinishing. There was also some water damage around the water fountain and patch repairs throughout, so it was clear the floor had been repaired previously.

How to Fix the Floor

The measurements of the wood throughout the floor and at the perimeter indicated there was sufficient wood remaining above the tongue to sand and refinish the floor. I determined that repair was possible; it would require board replacement, including inspection of the substrate to determine the extent of the damage. After the repairs, the entire gym would have to be sanded, remarked and finished. The insurance company for the event organizer was able to negotiate a settlement with the insurance company for the school district.



In the Future

Use of the floor should be restricted to the purpose it was designed for. Sport courts are complicated floors designed to offer some cushion while running and are not able to withstand this sort of impact.
