Market share of "non-standard" waterproof products in some regions reached 80%

The rainy season of the year is approaching, and the helplessness of “five bedrooms and nine leaks” will be staged again. The problem of building waterproofing has been plagued by people for a long time. When will the industry chaos be able to end? The reporter recently learned that misuse of inferior materials, Layered subcontracting and other industry issues have made waterproofing the weakest link in the "thousands of miles" of construction projects.

Poor waterproof products ramp up the market

Since last year, the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) has built waterproofing products as one of the 10 key products for quality improvement. This year, it also listed building waterproofing materials as one of the top 8 key quality improvement products. However, according to the results of the “three surveys” of the quality of building waterproofing membranes in the country, some critical and safety indicators still have hidden risks.

“In some regions, the market share of 'non-standard' waterproof products reached 80%.” On April 10th, Wang Xu, Director of the Information Department of the China Building Waterproofing Association, confessed in an interview with this reporter that “no It is very common for companies to produce waterproof products and “certified companies to produce unlicensed products”.

In recent years, I reported that reporters made unannounced visits to the market for waterproof materials every year. Through a follow-up survey of Fengjia District's Wujiacun Waterproof Building Materials Street, Sihuiqiao Building Materials Wholesale Market, and Jiuxianqiao Building Materials Decoration Market, it was found that "Three orders and five applications", but "non-standard" and poor quality waterproof products have been banned for many times. On April 10th, the reporter linked several waterproof products to the company's name “Buy Waterproof Materials for Site Renovation” and found that the problem of this year's waterproof market is still a lot. The price of waterproof products of the same brand and the same specifications and the prices of different merchants Can be two to three times worse, the quality gap behind this disparity price is also inevitable.

As for the reasons why "non-standard" waterproof products are popular, Wang Xu analyzed that this has a direct bearing on the low degree of concentration in the waterproofing industry. According to statistics from the China Construction Waterproofing Association, in 2012, the total output value of the waterproof industry exceeded 100 billion yuan, but there were only 10 companies with sales revenue exceeding 500 million yuan in the industry, and the top 50 companies’ market share was still less than the market. Two percent of the total. "This can easily lead to vicious competition in the industry. The direct result is the proliferation of inferior products."

“Some companies have turned a blind eye to standards because they are chasing profits.” Wang Xu said that “protocol products” that were originally higher in foreign countries because of special requirements and standards were turned into high-profit companies in pursuit of low prices and standards The poor quality custom products. Even in Zhejiang and other regions, there have been “Oolong” incidents where corporate standards are lower than national standards.

“At present, only the products related to construction safety implement production license management, and waterproof materials are one of them.” Wang Xu said that the impact of waterproofing on building safety is very important. However, with the decentralization of the country's management license for production licenses, the number of manufacturers of waterproof materials has soared in recent years.

Wang Xu said that these companies have spotted the rapid increase in water-proof market demand and are ready to “get a hand”, including companies that have coils, paint, glue, dry powder and chemical products, as well as building construction units. There are even unqualified “mud legs”. It is difficult for these “Halfway” production companies to guarantee professional technical standards, and the products and related services they produce are also uneven, so there is no guarantee whatsoever.

Then, what kind of harm will be brought to these construction projects when waterproof products with poor quality are applied to the construction project? Zhu Zhiyuan, member of the Suzhou Waterproofing Institute and Expert Committee, said that the role of waterproofing projects in construction is not merely a sense Waterproofing also protects the reinforced concrete structure of the main building.

Zhu Zhiyuan said that if there is a problem with the waterproofing project, the steel structure in the main structure of the building will be corroded and charred, and the life span of the construction project will be greatly shortened. The "non-standard" waterproof material in the market is difficult to achieve the 10-year service life in the technical requirements, which seriously restricts the life cycle of buildings.

Shang Huasheng, the head of the China Construction Waterproofing Association’s industry department, told reporters that if there is a problem with the waterproofing during the first pass of the construction process, the insulation layer of the building will also follow problems, and the cost of renovating is very large, which is equivalent to re-doing Roofing.

Shang Huasheng gave reporters an example of his personal experiences. “Pitch-grade composites that had been used for at least 10 years of service life have been powdered in less than two years. This material is finally seriously corroded like loess. Construction safety has brought about hidden dangers and is also a waste of social resources."

How low price people have to do

It is understood that in the construction industry this industry chain, the waterproof industry is the bottom and the bottom of the ring. “Professional waterproofing market is extremely chaotic. There are people who do low prices.” According to Wang Xu, the waterproof material market is chaotic and it cannot be attributed to the manufacturer. Because after the industry's first layer of subcontracting to reduce the price, to the waterproof link, the rest of the profits have been very few, and often even the normal cost price can not guarantee, the company desperation, can only choose to cut corners.

At present, the average construction cost of construction waterproofing projects in the world accounts for about 8% of the total construction cost. However, this figure only accounts for 1% to 3% in China. Therefore, construction waterproofing prices have only been operating at low levels for a long time. The difficulty can be imagined.

According to reports, the waterproof project usually uses the "total package system", that is, the total package of the developer to the civil total contracting unit, and then subcontracted by the total package unit to the waterproof professional company. Ye Linbiao, deputy director of the China Architectural Society's Waterproofing Experts Committee, once cited an example of a project he has participated in in a national investment project. His waterproof project budget is 150 yuan per square meter. The money arrived at the place and was first deducted by 20% of the management fee, and was issued to the general package at a price of 120 yuan per square meter, and the total package was finally issued to the construction party at a price of 60 yuan per square meter.

“The opening of this hole opens the door, and the effects of the back layers will show up.” Wang Xu said that the total package units often do not have the qualification for waterproof construction, so they subcontract out waterproof and decorative professional processes while keeping prices down. To make a profit. The subcontracting companies often subcontract the construction projects to other manufacturers with lower asking prices and divide them into “cups”, which directly leads to the massive application of the last inferior products in waterproof construction.
