In the field of building waterproofing, a profound conceptual transformation is reshaping the design and construction logic of roofing systems. Traditional "built-up roofing" adopts a "heavy" approach of stacking multiple layers of asphalt and felt, attempting to achieve waterproofing through material accumulation. In contrast, the "single-ply roofing system," represented by TPO and PVC membranes, achieves a fundamental shift from "quantity" to "quality" and from "layering" to "integration" with its lightweight yet multifunctional single-layer membrane.
Single-ply roofing refers to a roofing system that uses a single layer of flexible waterproofing membrane as the primary waterproofing component, working in conjunction with insulation layers, vapor retarders, and other components. Introduced to China in 1999, after more than two decades of development, it has become widely adopted in industrial plants, stadiums, airports, large commercial buildings, and other venues, emerging as a mai

Whether it's waterproofing and renovation of a residential roof or waterproofing construction of concrete roofs for shops and factories, the PVC mechanical fixing solution for concrete roofs has become a highly popular choice in recent years due to its advantages of high efficiency, strong stability, and wide adaptability among many waterproofing solutions.
What is mechanical fastening? How does it differ from traditional adhesive methods? Why is it suitable for concrete roofs? Can it be used on my own roof? Canlon will explain it all for you today.

Nongfu Spring's Dujiangyan Production Base is a comprehensive production base invested and constructed by Nongfu Spring in Dujiangyan City, Chengdu, Sichuan Province. Located in the Qingcheng Mountain Tourism Equipment Industrial Functional Zone, it covers an area of 446.7 acres and has a total investment of 1.35 billion yuan. The base adopts automated and digital production technologies and integrates industrial tourism functions, mainly producing drinking natural water and aseptic beverages.
This project is a core project of the "Tianfu Good Water" industrial cluster in Dujiangyan City. As a high-quality case of Canlon, it was honored to be selected as the Jinyu Award — Gold Award for Metal Enclosure System Engineering in 2025.

In recent years, China has been actively promoting the construction of new infrastructure, new energy and new industries in countries along the "Belt and Road". It has used "Chinese strength" to empower the infrastructure construction of Southeast Asia, Central Asia and even African countries. The export of building materials has become a major market hotspot. Canlon has also gone abroad through a "combination punch" of general trade and foreign aid projects, exporting "international quality at Chinese prices" and winning market share and reputation in foreign lands. Today, Canlon presents the latest "combined edition" of overseas projects.
