The water has been leaking through the damaged tiles over a long period of time.
So, lets get to work and see what the damage is under the tiles. Having removed the rotten board l’m left with solid timber to build up the platform.
I need to add a 19mm thick board to bring the level up to and ready for the new tiles.
Now l’m ready to tile this area but l’ve decided to use large tiles instead of the mosaic to cover a larger area.
After the tile adhesive is dry time to grout and add silicone to the edges.
Job done and water tight!
