Had a mason here who has recast our balcony slab. The thing is, now a new waterproofing layer needs to be applied. What should be used? It seems like a whole jungle out there. And I'm getting nervous now with the heavy rain that the concrete will absorb a lot of water.
The house is a 50s building and there are steel studs in the house wall that hold up the balcony. Had to remove the upper part of the old slab as it was in terrible condition and cast anew. The old felt that was between the concrete layers has been removed.
