summerrr 0 Report post Posted January 5, 2020 Hi guys, renovated my BTO flat 2 years back. so back then i did an overlay of the floor tiles over the hdb tiles. however i recently realised that there is a corner of the toilet where there is ponding during to floor gradient problem. So now i am considering to re-do my bathroom floor ties to solve the ponding issue. is it possible to just hack the overlay tiles and keep the original hdb tiles intact? will my waterproofing membrane be affected? or if i were to really re-do my flooring i have tp hack everything away, re-do the waterproofing as well? anyone done this before?
