Hi Gary. RaceDeck is one of the two most premiere manufacturers of interlocking tiles. SwissTrax is the other.

Hi Mary. You ask a great question! Typically, metal or plastic that is dragged across the tiles will not scratch them as long as they don’t have sharp edges.

Hello Don. When you installed the PVC tiles did you allow a minimum 1/2″ clearance from all walls and immovable objects (cabinets, support poles, etc.)? Secondly, did you install the tiles in the winter or cooler months? The tiles will expand and contract based on the overall difference in temperatures. How hot or cold it may get is not as important. If you allowed for the minimum 1/2″ clearance, then our guess is that the tiles were installed when it was much cooler. The initial clearance may have not been enough and the tiles are running out of room to expand.

The best way to fix the issue with buckling is to recheck the clearance of the tiles when the weather begins warming up just before you begin to encounter the buckling issue. Make sure there are not any vehicles or heavy objects on the tile at the time. If you are less than 1/2″ clearance required at that point, retrimming will generally fix the issue.

However as soon as the seasons started to change, the frustration began. The floor lies flat during winter months, but starts buckling during the summer due to warmer weather. Very frustrating. It doesn’t matter whether the garage door is open or not, the floor is buckled in several spots for 4 – 5 months. North facing garage door, west coast of Canada, so its not like its subject to scorching Arizona heat around here. Its been 3 years of this, its become such an eyesore that i’m ready to toss the entire floor in the garbage.

I find it curious to read that the PVC flooring needs to be able to expand / contract, yet how’s it supposed to do that with a couple 3500 lb cars sitting on it ? Seems like the change in temperatures combined with all that weight on it is the cause of buckling. Disappointing.
