apartments built by famous construction companies, water leaks from the ceiling of the house when it rains. It's been a while since the problem came out, but some houses haven't been renovated yet, and some are leaking. During this rainy season, residents were not alone in pain.

Rainwater dripping from the bedroom ceiling wets the bed.

It flows down through the door.

This has happened to some households right after moving in last July, but this summer, the situation is getting worse during the long rainy season.

Water tanks were supported around the leak from the apartment hallway to the bedroom.

The lower house has a trash can in the middle of the living room to catch the dripping water.

The ceiling and walls were also covered with mold.

[Apartment residents: Since it's old, there are lots of bugs on the ceiling. Since there are so many cracks, I am very worried that the watered ceiling will sink... .]

This apartment in Osan, Gyeonggi-do was built by POSCO E&C.

Of the total 2,400 households, 95 reported leak damage.

The construction company promised to do the repair work until February only last January, but some houses have not yet been renovated, and others have leaked water again after the repair work.

POSCO E&C said that water leaks from small cracks in the roof of the apartment at the time of construction, and that it will take fundamental waterproof measures after identifying the cause by generation.

Residents who had to experience a record rainy season amid construction and post-response not like a large-scale construction company are experiencing resentment.
