Recently, the Ministry of Housing and Urban-Rural Development organized multi-unit drafting of the national standard "technical specifications for roofing works (partial revision of the draft provisions for public comment)", for public comment. The document adds the requirement that the durability of the material should be compatible with the service life of the project waterproofing, which has aroused widespread concern in the industry, among which, the  service life of the roofing design is not less than 20 years has become a hot spot of concern.

 Roofing design service life

In fact,It has been mentioned in the consultation draft of the Residential Project Planning in 2019 that the service life of roof waterproofing design should be increased to 20 years, underground waterproofing not less than the designed service life of building structure, and the toilet waterproofing should not less than 15 years. The specifications are clear and detailed, and the standards have been significantly improved compared with the past. The draft of this "Technical Specification for Roofing Engineering" specifies the practices and performance of roofing waterproofing materials in more detail.

 Roofing design service life

Due to the long-standing lack of attention from users, the current national standards for waterproofing products have not changed significantly in the past 10 years. National standards can be seen as the industry access threshold, which has not been significantly increased for a long time, so the revision of the national mandatory standard is of great significance to the waterproof material industry.

The development of polymer membrane in my country is relatively lagging behind, and the overall technical level is low. It is necessary to implement a complete system supply in order to meet the diversified needs of the market. In recent years, Canlon has launched MBP HDPE pre applied waterproof membrane and PVC /TPO roofing membrane to meet the needs of different centralized procurement projects. There are various widths, thicknesses and even subdivisions of different construction schemes, which are gradually enhancing the Canlon's strategic depth.

The development of polymer membrane

Since the roof waterproofing design period has been increased to 20 years, the polymer single-ply roofing system represented by PVC and TPO roofing membrne may become the biggest beneficiary. As the most successful polymer membrane used in Europe, the biggest advantage of PVC waterproofing membrane is that the seams can be welded with longer service life, and the ecological effect is better than EPDM, TPO, modified asphalt and laminated asphalt membrane. The PVC waterproofing membrane in Europe has a successful record of 40 years, and the average lifespan of the PVC waterproofing roof in the United States is more than 30 years.The laboratory data of CANLON PVC has basically reached the average level of Europe and the United States.

planted roofing

durability requirements

Today, planted roofing is also on the increase, with the main drivers of growth shifting from novelty and environmental beauty to rainwater harvesting, limiting the heat island effect and saving energy. Countries such as Germany and Japan also implement subsidy and incentive policies for planting roofs.

The product standard upgrade of the waterproof material industry is led by the national implementation of the mandatory engineering construction specification system in the field of construction. The continuous improvement of the durability requirements of construction-related materials shows that the domestic emphasis on building quality is constantly increasing, which will promote the waterproof material industry to embark on the road of high-quality development.

We have been pursuing innovation and diversification since CANLON was established. At the same time, we have pursued the requirements of modernisation and construction sustainability, and all our products are designed and manufactured in strict accordance with national production standards. Today CANLON has created proud results in many fields.
