Shower leaking, concrete tray: any thoughts on fixing it in situ

Calahonda52 · 16-01-2021 9:43am #1

Have a leak in the shower so taking out the kitchen ceiling under its later today to see whats what: seems it has been leaking for a while from what I saw with a cheapo inspection camera that I shoved through a hole last night so need to have a good look and replace a good piece of the slab that looks very mouldy.
.
Just wondering, there are some cracks in the concrete tray so wonder are there any fixes: fibre glass, epoxy etc that folks have used.

The leak may be from around the tiles, not certain but if its the tray really don't want to have to rip it out.:(

Thanks as always

If the tray is cracked, get rid of it immediately. You will cost yourself alot more money stress and pain in the long run by doing short term fixes on it.

I'd plan on taking the bottom row of tiles out and the tray too.

In normal times I would agree but not really in the humour for all that now: new shower enclosure etc..

I had the exact same situation last year I fixed it up or so I thought then another leak developed.
Listermint is right don't mess with this. Replace it.Especially if it's an upstairs shower.

It's that or new kitchen ceiling and possibly electrical problems. Don't play with water it's never worth it.

I had to pull half a better square of tiles off from rear of shower as it was leaking for 8 months. A UK olive on Irish pipe behind the thermostatic shower valve dripping that long. Had not noticed until damp appeared on room wall next to it. Luckily bungalow with concrete floors. But still . Good bit of work . Reboard section and retile.

Might be a silly one but did you try an isolate the leak
Waste
Tray
Tile / tray junction
Shower door
Shower unit
Shower head
Might narrow it down for you
Any pics?

Thanks guys.
Its not the tray, it's the tiles, beading, in the corner?

I have most of the mouldy pb down and I can see where the water comes down so once I got that sorted I jumped up on my bike and went for a spin, too fine a day for working indoors!

Will start on the tiles tomorrow with my trusty multitool.

Sorry to hear Cal.

Can I ask what multi tool you use?

For this type of job a multi tool is invaluable with a tile head.

I've owned a Ryobi cordless it was rubbish died very quickly. Replaced. Second died quickly too.

Bought the DeWalt cordless. It just goes and goes and goes Excellent unit.

I bought the Fein corded one 240V when they first emerged from the automotive trade maybe 10 years ago

I know, ouch, when you see the cost, however it has been so useful, a recent use, cutting a strip off a T&G faced door to a press that was sticking at the bottom with the little semi-circular saw blade.
Its great for cutting out pb for switches and sockets etc
When I would be in the US, I loaded up with blades

I noticed the seal was gone on a pvc window sill in our bathroom. I pulled it off and it was mouldy. Replaced it with tiles which looks way better. Did the side of the recess where the window is because that was getting wet from showers too.

It took ages though for a few reasons. It takes time to dry, and it was easier to wait until one part was set in place and cut the next section to fit. Also I had to restart twice. First I was tiling on top of plaster which turned out to be crumbly and eater-damaged. Then I realised it sloped slightly towards the window. I changed it so it slopes slightly away from the window and was glad I did it. I also ran a dehumidifier for a couple of days before starting until the walls underneath were dry.

It was kinda horrible not being able to wash. So I suppose get everyone to wash before you start unless you have a second shower or bath.
