Waterproofing floor plan for a typical residential unit in a luxury building. It covers all the main wet areas like the kitchen, service area, the four suites, & the large balcony. Shows specific ‘Type 4’ waterproofing specs for flexible poolymer mortar with callouts for the regularization layers (usually 2.5cm to 4.0cm thick). I’ve marked all the slope directions and drainage points clearly with arrows and levels. The drawing is at 1:50 scale and uses metric units. Good reference for MEP or plumbing detailing on high-rise residential projects. Projeto detalhado de impermeabilização e caimentos.
