Damaged waterproofing - can it be repaired?

Question

Hi. We are renovating our bathroom with a tiled walk in shower but the tiler has placed the drain totally crooked. He now tried to remove and change it but damaged the waterproofing during this process. Can this be fixed in just the area where it got damaged or do we need to remove all tiles (floor and up the wall) and replace it entirely? What is the best solution please? 🙁

Hello  there.  Having  a long  time  experience on bathrooms  and shower rooms  can you trust  me  and  do what  I say.  Best option  is to remove  the floor  tiles  place correctly  the drain make the  water  tanking  and do the  new  floor.

Unfortunately if the enough of the tiles can not be removed around the drain
Without damaging the waterproof membrane
To re position the drain 
Then you will need to replace the whole wet room floor to ensure a water tight floor

Depending on the original type of waterproofing applied, I would purchase the mapie wps waterproof kit from screwfix and ‘paint’ the damaged area with it.. it is a rubberised paint so will dry fully waterproof. 
Hope this helps

Hi, It is possible to repair the damaged area with a liquid tanking sealer which is brushed on. More than one coat may be required and it must be left to dry fully before refitting the drain. Good luck !

Hi you can repair.You just need to clean it well and do it again

Martyn · Answer

It would need only be replaced on the floor but the complete floor.

The area can be patched if you use a water proof adhesive, cut a square and stick directly over but make sure the glue is evenly spread and allow to dry before replacing tiles.

Yes can be repaired as long as he uses right staff, like Mapei guard, or tanking kit.
