I have just moved into my new house about 3 months ago. We noticed a
bit of mold on the side of the shower. The builder came and took down
some gyprock. Behind the shower there is a black membrane. I found
about 6 inches of water behind that membrane. When I say 6 inches I
mean 6 inches high in water. The builder is trying to tell me that
that is normal to have water in the membrane. I told him that having 6
inches of water after 3 months is beyond ridiculous. He thought the
leak was coming from the shower door, I'm thinking its leaking through
the grout in the shower. The entire shower is in ceramics.

Does anyone have experience with shower leaks ? Does anyone know if
the membrane is suppose to have water in it ? I thought the membrane
was for if the shower leaks it will catch it. Not to actually collect
water regularly.

Any info would help.
Tks.

No, there should be no water there. Your contractor is jerking you off
(they tend to do this).

Look very closely (I mean very closely) at the grout joints!

Your absolutely correct in telling the builder that it is beyond
ridiculous. As a home improvement contractor, I have never seen 6" of
water in any shower liner in 35+ yrs.

If you see no cracks in the grout, then I would have to supect the
shower diverter or the shower head pipe connection. If you can remove
the access panel to the diverter, you should be able to check for
leaks. Water being in the pan/liner tells me that the water source is
at a higher elevation (diverter?).

Grout is not waterproof - water goes through it. It is supposed to then
"flow" through the backerboard behind the tile down into the shower
pan concrete, where it continues down to the weep holes at the drain.
Normally, this should be small amounts of water. The amount you are
seeing suggests to me either no path to the weep holes, or a significant
leak of water somewhere.

You can reduce water through the grout by sealing the grout, but water
will still get through it in small amounts.

If you have gyprock behind the tile in a shower, you have a problem.
Normally, concrete backerboard or some such material is used.
Normal drywall, or even "greenboard" won't hold up to the
moisture in a shower.

For what it's worth, I had a somewhat similar situation. My cause was a
pinhole leak in the water supply lines ... copper. But this was after
several years in the house.
