Did the property help the owner to release water before the balcony decoration?

If no one at home releases water to the property, it will cause unpredictable losses, so the owners will handle it themselves.

Before balcony decoration, the most important thing is drainage. The first waterproof refers to the waterproof in the balcony sliding door. Waterproofing refers to the waterproofing of the balcony floor. The third waterproof is to keep the balcony floor drain unobstructed.
