Tanking and travertine weight

[j3ff]

Hi all, first question following a short intro over at the intro page.

I'm just about to start fitting out an en-suite and bathroom in the extension I'm just completing at my place. Anyway, I've committed THE cardinal sin of changing my mind (or more accurately having my mind changed for me by the boss (missus).

In the e-suite I've aquapaneled the shower cubicle. Will house a 1200x800 stone tray with thermo mixer fed by a unistor pressurised tank.

Original plan was to tank this with wp1 or weber equiv. then tile with ceramics- all well within the 32kg limit for tanked aquapanel (paint on method).

Problem now is that missus has TOLD me we're having travertine so being the loving partner that I am I've duly complied and bought in 460x300
travs. However, these are probably over the weight limit (have no bathroom scales) but at just over 7 tiles per m2 my guesstimate is about 35kg - certainly heavier than a bag of cement.

As I definately want to tank the area (seen too many rotten floors etc) I am wondering what the best option is. Seems to me like the way to go would be to use a physical membrane rather than a paint on but I've not used these before and I'm not sure of the weight bearing limits for them.

Any opinions are most welcome


many thanks for indulging me

Hi jeff, Aqua panel should hold around 40kg plus....so if you use a membrane tanking rather than a solution kit then the weight you can hang does not change.

Thanks Dave,

any recommendations on the membrane? I've used the liquid type but not the physical barrier before so I'm all ears on that front.

many thanks
