    I work in the concrete frame business and would only reccommend Preprufe by Grace for tanking.

    There are only two products ever really used in basement tanking in apartment complexes in ireland and they are:

    Preprufe by Grace (sold via Brooks group or direct)

    Voltex by ceto (sold in heiton buckleys)

    I have used it and have had no probelms with it. Be aware that this only goes on the horizontal surfaces and that the proofex 3000 or 3000MR if methane and radon resistance is required. However, the choice of waterproofing membrane is dependant on the soil conditions and water table level. A bit more info would be great!

    Is the basement going to be habitable???

    Yes, the basement will be part of the living area, you can get an idea of the plans at the link below, go back a couple of months...

    watergate-house.blogspot.com

    The basement is above the water table and the ground does not appear to be water sodden in any way, however there is a little runoff from the surrounding ground. I am tanking 30 odd meters of vertical wall which will be all underground. In addition I am considering placing 60mm of Xtratherm in front of the tanking to protect it and to provide some level of insulation...

    Looking at the detail on your blog, it looks like you will have a cold bridge at the ground floor/external wall junction. Secondly your cavity does not extend beyond the ground floor slab, which isn't ideal either.

    Don't read too much into that diagram, the first thing is that the ground floor slab will be insulated as will the first floor slab. Second thing is that there will likely be a cavity of some description around the basement. I am still looking at options for this...

    I guess I can add a 40mm cavity and 100mm dense block in addition to the tanking and 60mm insulation.

    What you would recommend ?

    Interresting approach, generally I always detail the waterproofing on the outside of the concrete, but that leaves membrane on the edges of the foundations exposed to damage. what will the internal finish be? can you plaster over the membrane? if its to be insulated and slabbed then youll be puncturing the membrane every fixing you put in.
