What is the application if we lay impact flooring over existing low carpet? How does it stay in place?

When installing our 8mm Impact Rolls - Designer Series rolls over low pile carpet, you can honestly loose lay the rubber rolls over the carpet and it will stay in place. If for some reason when performing certain exercises the rolls were to me, which is very rare as these rolls are pretty heavy, you could add some double-sided tape under the rolls to keep them in place.
