Building waterproofing engineering is an important part of building engineering.
Building waterproofing technology is a sub-project and special measures to ensure that buildings and structures are not corroded by water and the internal space is not harmed.
The waterproof coating is mainly used in the housing construction industry and civil engineering construction industry, and the application amount in the construction installation industry, building decoration, decoration and other construction industries is relatively small.
Generally speaking, waterproof coatings can be widely used in indoor kitchens, bathrooms, balconies, roofs, basements, exterior walls, roof gardens, swimming pools, reservoirs, drinking pools, roads, bridges, tunnels, culverts and underground spaces of buildings.
High-speed railways, highways, subways, urban rails, airports, diversion canals, reservoirs, dams, hydroelectric power stations and water treatment buildings.
At present, the problem of building leakage is a common problem with prominent quality of buildings, and it is also a problem reported by users.
Leakage not only disrupts people’s normal life, work, and production order, but may directly affect the use of the entire building.
life.
It can be seen that the quality of the waterproofing effect is very important to the quality of the building, so the waterproofing project occupies a very important position in the construction project.
Completion area of houses of real estate development enterprises refers to the total construction area of all houses that have been completed in accordance with the design requirements during the reporting period, meet the occupancy and use conditions, pass the acceptance appraisal or meet the completion acceptance criteria, and can be officially handed over to use.
From 2003 to 2014, the completed floor space of real estate development enterprises in my country has shown a fluctuating upward trend.
After 2014, due to the oversupply of housing in many cities, the newly-started area of houses has decreased, and the area of completed houses has begun to fluctuate and decline.
In 2018, the floor space of buildings completed by real estate development enterprises was 935.
5 million square meters, a decrease of 7.
8%, a decrease of 4.
5 percentage points from January to November, and an increase of 3.
4 percentage points from the previous year.
Among them, the completed residential area was 660.
16 million square meters, a decrease of 8.
1%.
In the first half of 2019, the floor space completed by real estate development enterprises was 324.
26 million square meters, down 12.
7%, and the rate of decline expanded by 0.
3 percentage points.
Among them, the completed residential area was 229.
29 million square meters, down 11.
7%.
Building waterproof coatings are currently mainly used in the housing construction industry in the construction of new buildings and the renovation of existing buildings.
Calculated according to the thickness of the waterproof coating film per square meter of 1.
5 mm, the average consumption of the film per square meter is 2 kilograms, assuming a house renovation cycle of 10 years, combined with the calculation of the completed area of the real estate development enterprise house in 2003-2019H1, 2018 The total demand for waterproof coatings for completed buildings in China is 3.
041 million tons, of which the demand for waterproof coatings for new buildings is 1.
8710 million tons, and the demand for waterproof coatings for refurbished buildings is 1.
170 million tons; China's completed building waterproof coatings for the first half of 2019 The demand is 1.
0624 million tons, of which the demand for waterproof coatings for new buildings is 648,500 tons, and the demand for waterproof coatings for refurbished buildings is 413,800 tons.
According to relevant national plans, in 2015, the national housing sales increased by 18% year-on-year, but the inventory is still large.
Housing destocking is an important task in the early period of the "13th Five-Year Plan", which determines the slowdown in the growth rate of newly-started housing area; However, urbanization and the increasing refurbishment of old houses have provided a huge market space for the development of architectural coatings.
At the same time, since 2009, many ministries and commissions in my country have successively issued a number of policies to raise industry thresholds and guide small businesses from multiple perspectives such as issuing product standards, eliminating outdated production capacity, issuing production licenses, and publishing industry access conditions.
Enterprises withdraw from competition, thereby improving the competitive environment.
With the trend of consumption upgrades, downstream large real estate developers have become more stringent in controlling the quality of building waterproofing.
Branded, high-quality building waterproofing products and construction services will be favored by the market.
Based on this, it is expected that the demand for waterproof coatings for housing construction in my country will rise moderately in the future.
In 2020, the demand for waterproof coatings for housing construction in China will reach 3.
42 million tons, and the demand for waterproof coatings for housing construction in my country will exceed 4.
3 million tons in 2024.
