Newly tiled shower/bath is leaking

[faithhealer]

I once tanked the walls correctly, lipped onto bath (or so I thought) Floorboards had a bit of give and moved. had to remove bottom row of tiles and re do!

Its more likeley that when the Silicon seal is the problem, I would suggest that when you are squirting water directly at the Silicon its not leaking becuase of the angle your squirting at at, when your squirting it at the tiles the water is running down the wall to the top of the Silicon, the seal is probably leaking at the very top of the Silicon down the back of it, when its running down the wall its hitting this point and leaking through, when your spraying the Silicon directly its hitting it at an angle and running off.

Strip the Silicon off and redo it, why didnt your tiler do the siliconing??

was the bath full of water when it was siliconed and also was it left full for 12 hours ?

I've just done some more tests taking into consideration what everyone has said.

Spraying the shower head directly onto (from above aswell) the silcone there's no leaks at all. The leaks only start when I spray the around the first horizontal grout line so I'm pretty sure that's where it's getting in. If I spray there it leaks, if I stop spraying there and move down a inch or 2, it stops leaking. There's no visible cracks. I can only assume it's the grout itself that's of poor quality and is letting in water.

Tiler didn't do the final Silicon because I needed to install the shower screen and thought it best I do it all in one go rather than let him do a bit, then me do a bit later. Plus I'm 200% positive it's not the Silicon that's the problem as I take my time doing it, use only the best Silicon and do it well.

Silicon was left 24hrs+ before using the bath or shower also.

He's coming back tomorrow to have a look. And FWIW I didn't knock him down in price a penny, he was the most expensive quote but I'd seen his work previous and it was good and I wanted a good job.

My feeling is that he's used poor quality grout. It's not flexible as there's a big crack already down another section of wall away from the shower. He wasn't using a BAL or Mapei product, that's for sure but it was powdered grout from the tile chain 'Al Murad'. You know, as a customer it's difficult to insist that a tradesman use a certain product. I mean, he's tiled hundreds of bathrooms time and time again so what do I know type thing. Tradesman do not like customers telling them what to do do they?

Bill you've done the right thing by getting him back to have a look at the problem, and as a customer, you expect to get a professional in who knows what they are doing and what the best materials are for the job. The Tiler has a duty to fix any problems that have arisen, particularly if you have already paid him for the work done. Unfortunately, most expensive doesn't necessarily mean best quality.

But a tradesman should keep up to date on what the best materials are and for which purpose. Product development will be highly competitive between the major adhesive and grout manufacturers because each one wants to be a tilers first choice.

Good luck and let us know how you get on

 

[billhicks]

Yea, I know. When you get quotes for a job it's usually a letterhead and a price so can be pot luck if it's not a recommendation.

If I could offer any advise to any tradesman it would be to take the time to specify on your written quote that you will use the very best materials and do the job to the highest standard. Thus when I'm looking through the written quotes I've received yours is not just a price and a name/number like all the others...

How much water is getting through, if its alot then there must be a hole in the grout, and the tiles cant be fixed very well, considering that the grout is not only passing through the grout, then the adhesive that (should be) behind however many courses of tiles high the leak is. Im sorry but I cant envisige drips of water passing through the grout and the adhesive that much that quickly if the jobs been done right.

How long is it from spraying the water to the drip appearing, and how long does it drip for after you stop spraying?

 

[DHTiling]

I was just thinking that Oli...if water can pass and stop that quick then he has hollowness behind the tiles...

I thinkt he bottom row needs removing and check how much adhesive coverage there is..

It's a constant drip, one every 2 seconds at least. It takes a few seconds for it to start dripping (10-15) and literally stops dripping about 2 seconds after shower head is moved away from the place that leaks. Like I said previous, it's quite hard to believe from looking at it as there's no cracks or holes anywhere to be seen.

Tilers been back to have a look and he couldn't quite believe it either but the leak is evident. Plan is to seal the grout, Silicon up the corner and try and get some more Silicon under the bath where it meets the wall. If that doesn't work he says he'll take some tiles off.

Im sorry mate but I just cant see how water could be passing through the grout and the adhesive that quickly and consistantly, behind the tiles should be a bed of adhesive, Id be very interested to hear the results after the grout has been sealed, ask him if he dot and dabbed the tiles.

I cant believe that water could soak through the grout then adhesive in such a way, water soaking through in this manner usually takes a very long time to notice, and you usually only notice when tiles fall off or grout falls out of the joints, have you tried pressing something like a nail into the grout to see if its hard?

Im trying to make the best suggestion as to the problem it might sound like im having a go but im not, i really do think your barking up the wrong tree pointing the finger at the grout, my money would be on the plumbing leaking, perhaps water running down the shower hose or something when its on based on the frequency, I know you say you've isolated that and checked it all ready but I just cant see water passing through the grout and addy so quickly.

If water is passing through the grout and addy you should be able to pop the tile off easily, although id expect them to be falling off by now, what the surface under the adhesive?

Well, everything I've said has been 100% true so not much else I can say really. It's not the plumbing..

The mixer is an exposed bar mixer. Both the hose connection and the 3/4" connections are outside the wall on view. I'd be able to see the leak easily and the internal plumbing isn't leaking as if it were, it would be leaking whether the shower was on or not. If the internal compression fittings were leaking, the water would run down the hep2o pipe, not between the bath and the wall.

He didn't dot and dab but perhaps there is a gap where there's no adhesive where the leak is? It's behind the taps so perhaps it was awkward to get the trowel in? I dunno but the water is getting through the grout line, running down the tanked wall and out under the bath. Perhaps he used the trowel vertical in that area? and thus makes it easier for the water to run down the wall? I dunno again but I kid you not what I describe is exactly what's happening. Guess it just goes to show that grout really isn't waterproof and tanking is absolutely necessary. If it were just tiled straight on plasterboard I imagine the plasterboard would just soak up the leak and you'd never ever know about it.

The grout was 'Al Murad' branded stuff. Read: Mega cheap

I managed to get some more Silicon up under the bath between the edges of the bath and the wall. I'm hopeful that this + grout sealing + Silicon vertical corner will fix it.

 

[Olz]

I hope you get it sorted mate please let us know what the problem was and how it was rectified.

It shouldnt matter which was he used the trowel, I think your meaning that the troughs in the adhesive when its combed with the trowel and running vertically instead of horizontally, but this shouldnt matter as they compress when the tile is pushed into placed, the peaks collapse into the troughs making one flat bed of ashesive, like the jam in a sandwich, I suspect he must have dot and dabbed or left the area behind the taps with no adhesive behind.

Sealing the grout may solve the problem if the grout is the cause, but bear in mind the sealer wont last forever and is going to need resealing to prevent further leaking periodically, you should try and make sure there is no water left behind the tiles aswell or your going to trap it behind the tiles.

Id be insisting as a customer that the effected area's tiles be removed and refixed properly. If a jobs worth doing its worth doing right and all that.

Al Murad grout is palace rebranded I think, was it branded Al Murad or was it Granfix, Ive used both and there usually OK, although i had some problems with granfix cracking recently, but that was the gray one and seems to have been a bad batch at my suppliers.

 

[billhicks]

It wasn't granfix, I used that before when I tiled our floor. It was Al Murad branded, yellow bag and inside I think you get a few clear plastic bags of white grout.

Adhesive was Al Murad branded as well, white tub.

 

[Olz]

Im almost certain that the al murad tubbed adhesive is palace rebranded, although im not sure its suitable for use in shower areas.

What size are the tiles?

Edit: I've just looked at your pics, I would say that the tiles are too big for a tubbed adhesive, the fact that it may not have set may explain how the waters passing through it so quickly, is the water dirty when it drips through?

 

[billhicks]

Tiles are 300x450x10. Water is clean as a whistle.

All I remember from the tub was that it was white with green/yellow al murad logo and it said non-slip on it.
