So where does the water go?

Depending the amount of use the shower gets

thats why I use a solid bed trowel in wet areas Dan, to stop the water ingress running down the ribs and pooling at the bottom.

Nah I mean generally. The adhesive will still get water into it, even a solid bed. And if a family power shower is ran 3 times daily for 10 minutes say, it eventually does travel down to the bottom I guess?

the water would absorb into anything porous ie your cba and your grout or the...or absorb into the rear of the tile if it were ceramic.

if there was a section of grout missing grout, then the water ingress would be drawn back through the hole in the grout by capillary action, but again, some of the water would be absorbed into anything thats is porous..

oh and if the water was being drawn in at a rate that exceeded what the area could hold, then the pressure would build up and eventually 'pop' the tile off the wall..

^ and that ^ :lol: :lol: :lol:

When I do a shower area I tank the screed but this tanking is carried into the pot below the main stainless steel trough,




So any water that gets behind the wall tiles or through the floor would eventually hit this membrane and find its way into the drainage system.




In a house I would use something like this.. McAlpine Plumbing Supplies | Product Menu codeTSG1T6SS

Then any leaks can always be contained.

[/ATTACH]you might need to look into something like this doug called puddle flanges you install them then waterproof over the edges

Very similar to the McAlpine system Jay, I have never understood why these traps are not a building regulation requirement.

there virtually law here as doug says were does the water go now you know if you dont use them i hope your adh is suitable for swimming pools

My bathroom shower areas are tanked, but despite using the correct materials and tools, and siliconing alll the joints, water is getting through somewhere. I know this because the water find it's way out where the edge of the wall tiles meet the exposed corner of the bath on the outside. So the tanking system is working, but I'm still diagnosing where the pesky water is getting behind the tiles.

For me it will mean a whole re-grout and re-Silicon. I suspect it's seeping through the grout but it all looks sturdy and solid to me, so trial and error. There's no embedded pipework that could be leaking and it only happens when we use the shower over the bath.

GRR you using an over bath screen? If so id lay my money on the water getting through there somewhere. Sometimes they can let water through the gap between the male and female channels and through the hinge mechanism at the bottom.
Iis quite common to get a damp patch by the edge of the bath at the base of the screen, just needs drying off and some additional Silicon at the base of the hinge.

Just to add to Scottley's post any drill holes for the hinges etc, in fact all holes in tiles should be filled with Silicon.
