On June 5, 2026, Canlon was granted an invention patent, "A Test Device for a Siphon Drainage System of a Membrane Metal Roofing", patent number ZL202311789137.5. This marks the formal integration of "active drainage" into the core capability of the membrane metal roofing (Fusion® integrated panel) system, in addition to "waterproofing"—the "integrated waterproofing and drainage" concept has moved from a theoretical concept to a testable and verifiable engineering practice.
The National Building Standard Design Atlas 25J950, "Building Waterproofing," is an important guide for professionals in the building waterproofing industry. It provides detailed descriptions of waterproofing projects for metal roof panels and polymer membrane metal composite profiled sheet roofs, offering a unified and scientific technical reference for the Chinese building waterproofing industry. In the compilation of this national standard atlas, Canlon not only contributed its waterproofing expertise as a participating unit, but the technical standards for its representative innovative product—the polymer membrane metal composite profiled sheet system—were also included in Chapter 10. Let's take a look at the relevant content.
In 2021, CCTV's "News Broadcast" featured a special report on a benchmark urban renewal project—the Taizhou Old City Renovation Project in Zhejiang Province. The video showcased the Taizhou Jiaojiang Bridge East Project, constructed by Greentown Leju, as a model, demonstrating how the living environment of residents in the old city area has been improved. This project is one of Canlon's representative works in the "urban renewal" journey. Taizhou's old city area suffers from numerous dilapidated and unsafe buildings, prompting residents to yearn for relocation to new homes. Taizhou City Development Group, Greentown Construction Management, and Fangyuan Construction, the general contractor, all possess high-quality resources from front-end planning and design to back-end property management. Supported by robust product and management standards, they have accumulated extensive resources covering the entire industry chain.
The roof is the part of the building envelope most directly affected by the external environment. The design of its waterproofing and insulation system directly determines the building's durability and energy efficiency. Based on the relative positions of the waterproofing layer and the insulation layer, flat roof projects can be divided into three basic types: upright, inverted, and sandwich. Understanding the principles and applicable conditions of these three structural systems is fundamental to roof project design.
Recently, Typhoon "White Dolphin," the 11th typhoon of the year, made landfall twice along the coast of Zhejiang Province, bringing torrential rains and gale-force winds as it moved northward. Its impact extended across Zhejiang, Shanghai, Jiangsu, Anhui, Hubei, Henan, Hebei, and beyond. Meteorological forecasts indicate that after its remnant system combines with cold air, the Beijing-Tianjin-Hebei region and Liaoning will also experience significant rainfall. Typhoons test not only a city's drainage infrastructure but also push building roofing systems to their limits. Intense rainfall combined with instantaneous gale-force winds subjects roofs to immense water pressure and powerful wind uplift forces equivalent to a Category 17 super typhoon—any weak link can lead to leakage or even structural failure. In this extreme weather challenge, Canlon's polymer waterproofing systems delivered a performance that stands up to scrutiny.
Canlon is one of the first building material manufacturers in China to apply waterproofing products to nuclear power projects, contributing to numerous high-quality projects such as the Rongcheng Nuclear Power Plant in Shandong, the Sanmen Nuclear Power Plant in Zhejiang, the Xiapu Nuclear Power Plant in Fujian, and the Fuqing Nuclear Power Plant. The Fuqing Nuclear Power Plant unit project, in particular, won the National Excellent Project Award (Gold Award). Canlon's flagship product, MBP-P polymer self-adhesive waterproof membrane, passed the supplier certification of China National Nuclear Corporation (CNNC) and was also awarded the "Jiangsu Excellent Product" certification at the 2nd Jiangsu Quality Conference.
In 2021, based on the principles of "in-situ regeneration, gradual renewal, and respect for history" and combined with the renovation needs of the century-old school, Canlon tailored a flooring project for Nanqiao College in Fengxian District, Shanghai. In high-traffic areas, accidents such as falls and slips are common, necessitating protective and slip-resistant features. Simultaneously, the reality of frequent foot traffic creates an objective conflict with the ideal of a quiet teaching environment, easily disrupting normal teaching. Canlon Flooring 's products, possessing high strength, wear resistance, chemical resistance, and environmental friendliness, offer a variety of system solutions tailored to different needs in various settings, perfectly solving this problem.
Water damage below ground can ruin a building’s foundation. How do you protect these vulnerable areas? Below-Grade Waterproofing is essential to stop water infiltration and preserve structural integrity. In this post, you’ll learn what below-grade waterproofing is, common challenges, and how differe
Structural Waterproofing is essential for protecting concrete structures from water ingress, hydrostatic pressure, and long-term deterioration. This guide explains the causes of structural water damage, compares Type A, Type B, and Type C waterproofing systems, and outlines key selection criteria based on soil conditions, environmental grades, and building requirements. It also covers quality control, testing methods, and common installation challenges, helping engineers, architects, and contractors choose reliable waterproofing solutions that improve structural durability, reduce maintenance costs, and extend building service life.
