With the release of new waterproofing regulations, the construction industry has stricter requirements for waterproofing materials, which has also given rise to more innovative waterproofing materials. In this context, Himei waterproof tiles are very popular as an emerging waterproofing material.
The Ministry of Housing and Urban-Rural Development issued an announcement on October 24, 2022, announcing that the “General Specifications for Waterproofing of Buildings and Municipal Engineering” has become a national standard, numbered GB55030-2022, and will be implemented from April 1, 2023.
This means that the general code will become a mandatory engineering construction code, and all relevant provisions must be strictly implemented. The issuance of this general specification aims to strengthen waterproofing measures in construction and municipal projects and ensure the quality and safety of buildings and infrastructure.
According to the provisions of the general specifications, the roofing project should not be less than 20 years, the indoor project should not be less than 25 years, and the underground project should not be less than the design service life of the engineering structure (generally 50 years). The design service life of the waterproof project should be increased. Stricter requirements have been put forward for the quality and durability of waterproof material products, which means that low-end and inferior waterproof products will be gradually phased out.
Himei waterproof tile is a product made of TPO waterproof membrane and steel plate. It combines the common advantages of TPO and steel plate. It not only has good waterproof effect, but also has a promised service life of more than 25 years.
According to the provisions of the general specifications, the irradiation energy of exposed roof waterproofing membranes should not be less than 5040KJ/(㎡·nm). Compared with ordinary roof tiles, Himei waterproof tiles can undergo more than 10,000 hours of artificial climate aging experiments.
According to the provisions in the general specifications, the waterproof requirements of three different levels have different thicknesses. The waterproof membrane thickness that Himei waterproof tiles can choose is between 0.2~1.8mm, and various grades of waterproof roof tiles can be supplied.
The lap seam is the weak link of the membrane waterproof layer, so the performance of the seam is stipulated. Himei waterproof tile has a unique patent for high peel strength. The peel strength of TPO and steel plate after composite is >5.3N/mm, exceeding the specification of 3.0N/mm.
As an innovative waterproof material that meets the requirements of new waterproofing regulations, Himei waterproof tiles have broad market prospects and development potential. With the construction industry ushering in new waterproofing regulations, choosing Himei waterproof tiles can not only meet the strict requirements of the new regulations, but also protect the roof from damage, provide anti-corrosion, heat insulation and weather resistance, providing long-term protection for the building.
