Hi,
I've specified concrete floors in the bathroom/laundry. The builder protested using a admix in the slab, so he poured most of the slab, laid a waterproofing membrane, then poured the topping.
The PCA now says he won't certify the waterproofing because of where the edge of the shower recess meets the frame - the standard waterproofing membrane isn't present there.
I'm meeting the builder tomorrow morning. Please let me know; what are my options here?
