ELI5: What keeps a bowling lane from getting warped from thrown balls?

You always see those bowling ball videos of people punching through the ceiling and it coming back down, and you can hear it occasionally in public lanes where the release isn't really on point, so what keeps the wooden lane from getting warped, dinged, or dented?

Wood lanes are shaved down usually every 2 years. Also the lanes are not 1 continuous piece of wood. There are sections. The front part of the lane (where balls land) are made of a harder wood.

 Most lanes today are made of a synthetic material. Also in sections that can be replaced.
