I appear to have a leak in the bathroom floor. The room was created seven years ago to provide a wet shower area using an Impey aquadec former and the dry area to include Warmup UFH. The wet area is covered in 25 mm square mosaic.
A crack was discovered in one of the dry area tiles after about a month. The repair involved relaying another area of tiles on top of all the existing ones.
Recently, I have noticed that water appears to rise through the grouting in the dry area when you put exaggerated foot pressure on certain areas of the floor. Also, water has entered through cracks in the mosaic grouting (water rises up through the grout when standing in certain positions in the wet area). This is usually in the opposite side to where the shower head is.
In addition, one of the wall tiles in the corner below the shower sounds hollow when tapped and it is evident that there is a gap around the grouting.
An under floor inspection shows some of the support noggins are wet with fungal growth. This is the noggin supporting the floor directly underneath the shower. However, one of the floorboards running the length of the floor in the "dry" area is also black and mouldy.
The photo showing the Tilesafe membrane, has the junction between tanked and non tanked area corresponding with the line of this damp floorboard.
There is ingress of water from the corner wall tile, but also through all the cracked grouting in the mosaics. It appears, that no tanking was laid up the first course of wall tiles.
Can this situation be repaired without gutting the whole floor area and starting from scratch? I’m concerned about repairing the damp floor boards in the dry area. If water has managed to find its way up through two layers of tiles, how much damage is there on the plywood that is hidden from view.?
