Can this tile withstand hydraulic floor jacks and/or jack stands? Will water be trapped below, causing fungus growth?

We don't recommend placing floor jacks or stands directly on our Solid Tiles w/ Raised Squares as they will damage the tiles. If you wanted to use either on these tiles, we recommend placing a piece of plywood or a steel plate under them to keep from damaging the flooring. These tiles are mold and mildew resistant and are resistant to fungal growth, so if water does collect under the tiles, you will not have to worry about any issues.
