Help. Drywaller screwed concrete board through new shower pan liner.
I am currently remodeling my basement and hired out the drywall installation. Yesterday, I noticed screws at the bottom of the concrete board similar to the installation of drywall. The pan liner goes up the wall 6", and the screws are 1/4 off the floor in the shower.
I am concerned the shower pan liner will no longer be effective and water will leak out over time. How can this issue be resolved?
