"The problem is too serious, you can come to the scene and see it."
The owner of the Kapok Garden Community on Ocean Flower Island No. 3 revealed that in January this year, some owners in the community found that there were serious quality problems in the underground car inventory near the unfinished building "No. 421", the surface of the load-bearing column and load-bearing wall was bulging and cracking, the concrete was large and fell off, and some areas were even in a pulverized state.

According to the pictures and video information provided by the owner, the reporter observed that with a slight kick on the tip of his toes, the concrete of the load-bearing columns and load-bearing walls in many places in the basement will fall off in large pieces, revealing rusty steel bars. When the owner shot the video, he pointed out that "when the foot of the load-bearing wall of the basement of Building 428 was kicked, a large piece fell down, and the steel bars inside had been seriously corroded." ”

Ocean Flower Island Underground Garage "Out of Danger"
The owners of Ocean Flower Island said that the columns and load-bearing walls of the underground garage have been cracked in a large area, the concrete has been pulverized and peeled off, and the steel bars are exposed and severely corroded.

In view of the supporting role of the load-bearing columns and load-bearing walls of the basement for the entire high-rise building, the owners are worried that the continuous deterioration of these "dangerous conditions" may have a serious impact on the structural safety of the high-rise building, thus bringing a huge threat to the personal and property safety of the residents.
What is even more puzzling to the owners is that some of the load-bearing walls also have regular or irregular brown dots on the surface, which is suspected to be caused by the seepage of water outward after the rust and corrosion of the steel bars. These brown dots are full of brown powder inside, and some areas are accompanied by water seepage.

The aging of the walls is not accidental
It is no accident that the house is aging and all kinds of stubborn diseases. In addition to the use of materials, it also has a lot to do with the environment in which the house is located.
Ocean Flower Island is close to the sea and has a warm climate, if the exterior walls of the houses are not specially treated, the salt and moisture in the air will slowly enter the concrete, corrode the interior walls and steel bars, and accelerate the aging of the houses.
Ocean Flower Island is not alone, and most houses will have various problems after reaching a certain age limit.
The problem of leakage on the roof and wall of old houses has always been a "heart disease" for many residents. Some residents reported that the materials used in some buildings are very poor, and they will naturally age after about 10 years of use, and they need to be renovated and repaired.
In the 40 years of reform and opening up, the real estate industry has developed rapidly, and a series of buildings lacking safety and security have become the hot spots of major media exposure, and the increasingly prominent contradiction between owners and property companies has become one of the main contradictions in society.
In recent years, there have been many accidents in old houses across the country, which has also become a hot spot for complaints and feedback from residents around the country.
Relevant data show that at present, more than 170,000 old urban communities have been reported to need to be renovated, involving hundreds of millions of residents. However, due to the problem of capital operation, the renovation of old communities in some places is slow.

There is a lot of room for repairs
At present, the development of the housing repair market is facing problems such as large demand, imperfect market supervision system and non-standard market order.
According to the "2020-2025 Housing Repair Industry Market Survey Analysis and Development Trend Forecast Research Report" released by the China Research Industry Research Institute, the current market size of China's housing repair industry has reached 3.54 trillion, with a compound growth rate of 11.1% from 2015 to 2020; Among them, the home improvement and building materials market is 1.06 trillion, with a compound growth rate of 5.5%; the home improvement soft decoration market is 1.59 trillion yuan, with a compound growth rate of 15.5%; The home improvement service market was 0.88 trillion yuan, with a compound growth rate of 11.1%.
At the current growth rate, it is expected that by 2025, the overall housing repair industry in mainland China will reach 6 trillion yuan.
At present, there are many companies in the market that have played the sign of "repair", but they often only focus on specific areas, such as waterproofing, leakage, etc., and cannot solve a variety of building quality problems. If we can provide customers with one-stop professional services from inspection, identification, repair to maintenance, this will be another scene in the construction industry.
