Do you need to cover the geotextile?
Do not need, bathroom waterproof can choose a professional kitchen and toilet waterproof paste, or K11 waterproof slurry, water and electricity transformation, as long as the direct brushing on the base surface can be done until the waterproof layer can do 48 to 72 hours Of the closed water experiment, no problems can be posted after the brick.
Generally less than geotextile, I am specializing in the production of geotechnical materials
