Existing waterproof layers are handled differently depending on the condition
Homepage Frequently Asked Questions advises constructing the existing waterproofing without removing it if it is not too exciting. If the floor is bumped or excited, just remove the area, perform gradient work, and construct the waterproof panel.
The reason for the
excitation is that the waterproof layer holds the east wave, which repeatedly freezes and melts during the four seasons. The moisture under the panel is discharged by the built-in degassing base (air vent) .
It is instructed that the floor will be raised about 2cm after
construction. It's also a good idea to check the threshold of the rooftop entrance or the height around the drain.
construction period by area and consultation preparation
The construction period described in the
FAQ is 2 days based on 20-30 pyeong, 3-4 days based on 100 pyeong, and 7 days based on 200-300 pyeong. Actual schedule will vary depending on site conditions and weather.
