About Heavy Rain Damage

Continuing from yesterday, we will talk about heavy rain. First of all, we pray for your safety. Depending on the area, river flooding, underfloor inundation, overfloor inundation, and landslides have occurred, and damage to buildings has reached the management company.

In our case, there was a leak in the basement of a five-story building with a basement floor. The damage was not terrible, but it requires future repairs. This time, we were contacted via a renter and we were informed that there is a water leak in part of the underground tenant area. There are 2 places, 1 is place where we go downstairs to the basement, and 2nd is place of wall where we open 2 doors and go into the inside.

First of all, for those with little damage, it was found that rain leaks occurred via the refrigerant pipe of the outdoor unit of the air conditioner. An outdoor unit for an air conditioner is installed above the entrance to the underground tenant, and a refrigerant pipe is connected by drilling a hole in the slab of the building. Perhaps a gap was created in a part of this hole, and when a large amount of rain exceeded the drainage capacity, a part that overflowed was entering the room through this gap. As a repair method, use putty for filling holes, which is used for air conditioner piping. It is a case that can be repaired without using special occasions or equipment.

The other part of the damage was rainwater that accumulated on the side of the building, the neighboring building on the west side, and the site between the buildings, overcoming the waterproof level and flowing into the interior of the building. Perhaps over the years, the tarpaulin has deteriorated and waterproofing is not working. In this case, the repair method is expensive. It is possible to repair by reattaching the waterproof sheet from the start of the foundation, including the waterproofing of the wall surface. Alternatively, we can install eaves on the wall, install a gutter, and let the rainwater escape to another.

Since this is a repair that involves costs, we will discuss with the owner, the construction company, and our company, and we will proceed with measures so that the lessee is not disturbed.

 There was also a leak report in another apartment. This is a 1R apartment, which has been repaired 7-8 years ago. However, at the time of the initial renovation, the roof was not changed, so the damage occurred this time.
At the water leak point, water drops from the gap between the fluorescent lights on the kitchen. Perhaps some of the roof tiles are damaged or misaligned causing rainwater to enter. Here too, we will have the construction company respond promptly and investigate the roof.

As a management company, we will rush to carry out restoration activities, considering first whether the tenants are not harmed or the building is not damaged. Until now, such damage was rare in the rainy season, but it is unknown in the future. By the time the typhoon season comes, we will repair the building and manage it so that damage will not occur.
