Looking for waterproofing advice

[Lisak1]

Thanks @brokensword !

If these guys will do it, it's definitely worth trying. This is inside their showroom/warehouse so I'm sure they wanted to make sure it was leakproof.

EPDM LINER is the most common type used in ponds today. Not sure why your local feels that way but if i was to do a window a rubber liner would be far in the way of my choice as it is used as washers for many uses and thats what your trying to do create a seal

I would treat it like a shower and cover it with Ditra, then cover it with a rubber membrane such as the stuff they sell at the Home Depot in the tile area. Tile can be applied to the rubber membrane with thinset and Ditra is meant to be applied with thinset I would guess that the thinset would stick to your existing rubber base. Look at Youtube on how Ditra fabric is applied.

If your referring to a Mudd job thin set doesn't stick very well to the rubber its more a encapsulation layer that keeps water from getting to the substrate. generally a thicker layer is placed within the tub that just fills the area gets locked in more then it is stuck to the base/rubber. Does thin set grab to rubber yes but flex it and watch it pop off.

I just recently watched a tv show with the king of concrete jungle pools. Not my Favorite that's for sure he usually builds way over the top concrete monsters with fake palm trees etc. Not my style ... However they were using a spray on liner that was 4 x flexible and came in different colors i have no idea who what where to find the stuff but i would definitely fix your issues. the spray was not from a can or a sall compressor. it was more like a gunnite spray system
