Wht areas are you discussing tanking with the customers - is it around the bath or shower enclosures?
With proper substrate preparation,correct materials,good tiling and silicone use your work will last the life of the average bathroom. At least in the time I've been tiling most areas were never tanked.
However as technical developments occur we have to take on board these improvements to our trade and pass our knowledge onto the end user. Not all will embrace this additional cost as you have found so its through initiating them that the market will improve.
I have just taken out a shower tiled on plaster board and it was perfect. The tiling wasnt great and the grouting was shocking.
However the plasterboard was dry and no black marks at all, and it was 25 years old. In my opinion for every shower that we take out thats black and soggy there are a high percentage that are dry.
For all the failures that i have replaced, and there are many from my days of rental property work, the failures are down to the 4 things; poor quality of tiling, grouting, siliconing and tubbed adhesive.
However with the shower technology we have seen introduced over the last ten years with ever more powerful showers then need for extra protection has increased massively.
Most customers relate to tanking as something which is done to cellars as that propbaly the only place the have ever heard of it being carried out and usually expensive!
