Tanking Tape Install Help

[Stevev]

The trouble is Steve that all back grounds are normally gypsum which suck water up like a sponge, in 84 we rendered shower areas which were block based for the London underground in the lower areas of the office block which was being refurbed and they were for the engineers to have a shower and tiled with Quarry tiles.

Solid as you like.

so are you saying always tank OR use a hardi-backer type background and tank the seams?

What I'm saying is the materials used now for building are all dri lined for a speed construction and the general public want wet rooms which dos'nt allow gypsum to be used, yes they need tanking now due to the amount of water that gets pumped into a shower area.

Whatever system is used works for them and yourself.

Water-resistant materials are not watertight. The tanking of water-resistant material makes them watertight. There are many different shower wall substrate materials in the market. Some are not water resistant, some are water resistant and some are watertight. Don't use non-water resistant materials, tank water resistant materials and at least tape watertight materials.

Just a thought.....if you get asked to re-tile the walls round a bath that has a shower over it...and the walls turn out to be render and plaster or even if it is dry-lined....bearing in mind the BS....would I need to take out bath and put water-resistant/tight backing up, tank put bath back..then seal the edge and then tile.?? seems a lot of bother and expense to re-tile...??

You don't have to do anything. Most people wouldn't go to that length, although it's the best way to do it
