It turns out that there has been SBS waterproofing membrane under the cement protective layer of the balcony? If not, then look at whether there are cracks in the ground, you can use high-pressure grouting polyurethane, and then make a two-layer Henkel waterproof coating on the surface, and then paste tiles.
One is a design problem, such as the width of the balcony exceeding the design requirements; the second is the construction quality problem; The third is the problem of foundation settlement.
As long as the property allows, you can make the terrace into a sunroom.
There will be many reasons for water leakage, it will be that the waterproofing of the roof terrace is not in place, or the waterproofing of the intersection of the wall and the roof of the terrace is not in place. Check in the bud.
After the paint is dry, it can be ventilated without peculiar smell. Eighty or ninety percent of the harmful substances can be volatilized into the air after 12 hours of paint, and they can be ventilated!
