Hello, We have major renovation work when buying our house (we should not even talk about renovation given that everything is redone with the exception of stone exterior walls). As such we had a shower (classic, not an Italian) with a shower tray relatively flat (4/5 cm). This shower is surrounded by faience glued on plastered brick partitions. I specify that all the work was done by professionals in late 2009. But now, we find that behind the walls of this shower there is water infiltration not beautiful at all and inspecting the shower more closely we noticed many cracks in the joints of the faience or even places where the seal was gone / was absent. Especially at the connection with the shower tray. The consequences: beautiful water infiltration in the wall and painting on the other side of the wall that starts to blister and another partition that shows beautiful traces of moisture I want to know the possible remedies with the company tiling. I contacted the latter a week ago and she had to contact me again (I'm waiting...), the person I got on the phone just directly incriminated me by telling me that I had to redo my silicone joints ( that I had not thought about it, but to make a joint on a joint of faience absent, is this normal?). To complete this information: I was told about the mandatory implementation of a SPEC, but I see nothing of the kind on the quote or the invoice of my tiler (apart from a mention "shower blocking" ), it would have been able to avoid the infiltration (a priori no, but one never knows). In the other bathroom I had redone, the tiler (another) used sealing rods, it would not have been more judicious than the small silicone seal?

At the description of the facts, the company probably did not perform the work properly. Theabsence of joints promotes infiltration, but you must know that it is neither earthenware nor jointsseal the showerbut at the support: brick, plaster tile, plaster, plasterboard, etc.
In concrete terms, the company should, before laying the tiles, apply a sealing coating on the floor and the walls concerned by the splashing water. This primordial action is unfortunately sometimes "forgotten" by some professionals.
At the current stage of the damage noted, only one solution is required: remove all the faience and resume work "in the rules of art"
The works dating from 2009, the company should re-intervene under the ten-year warranty, although it is an equipment and not the main work. Put it in default to carry out a resumption of work under the defective and the contractual guarantee. Refuse one-off repairs that would save the company time and (possibly) end the warranty.
If the company denies the facts, then you will have to initiate legal proceedings with the Court of Instance, with expertise to the key.
