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.
In 2020, Canlon successfully won the bid for the construction and management materials (bridge waterproofing layer materials) of the new Aksu-Alar Railway, thanks to its excellent product quality, technical service advantages and outstanding cost performance. It provides reliable waterproofing materials to safeguard the railway construction. Canlon Waterproofing Co., Ltd., with its waterproofing quality and supply services adapted to China's high-speed rail and "China Speed," has won recognition for this key western development project and is a source of great pride in contributing to national infrastructure construction!
Recently, the bidding results for the 2026-2027 waterproofing engineering subcontracting framework agreement of the Urban Construction Branch of China Railway Wuhan Electrification Bureau Group have been announced. Canlon Construction Engineering Co., Ltd., a subsidiary of Canlon, was successfully selected and will work with the Urban Construction Branch of China Railway Wuhan Electrification Bureau Group to provide systematic waterproofing solutions and high-quality waterproofing materials for key urban infrastructure, rail transit, and municipal engineering projects, jointly safeguarding the high-quality construction of urban infrastructure.
Currently, many homeowners are experiencing problems with dampness, efflorescence, mold, and damp walls and floors in their basements. Even after repeated grouting, painting, and application of roofing materials, these issues persist. The core reason is that continuous "passive water blocking" can only address surface water and cannot solve the problem of gaseous water and capillary water that continuously seep into the pores of the concrete. Electro-osmosis moisture-proofing (electro-osmosis solution) is currently the mainstream and mature technology in the renovation industry for addressing persistent dampness in basements. Unlike traditional sealing methods, it provides a long-term solution to dampness problems at the structural level. Today, Karen Renovation will break down its principles in layman's terms, clearly explaining its applicable scenarios, practical effects, and advantages and disadvantages.
The siphon phenomenon is a natural phenomenon in fluid mechanics. It utilizes the weight and pressure difference of the liquid itself to easily draw the liquid from a high place to a low place without the aid of an external pump. Canlon's siphon roof drainage system relies on Bernoulli's fluid dynamics equations and is equipped with self-developed hydraulic calculation software to accurately match pipe diameter and number of ducts, ensuring stable siphon activation during extreme rainfall and forming full pipe flow. This is different from traditional gravity semi-pipe drainage and achieves rapid drainage.
In high-end industrial sectors such as new energy, precision manufacturing, and biopharmaceuticals, buildings are no longer mere shelters from wind and rain. A lithium battery plant workshop must strictly maintain temperatures below 25°C and humidity below 30%; otherwise, battery performance and yield rates are directly affected. If air quality fluctuates in a semiconductor cleanroom, the entire production line may face shutdown. In such scenarios, the roofing system is no longer just a waterproofing layer, but a "Super Shield" that safeguards production safety, product quality, and operational efficiency. Polymer waterproofing membranes represented by TPO, with their comprehensive properties of weatherability, energy-saving high reflectivity, chemical corrosion resistance, and wind uplift resistance, are becoming the preferred choice for high-end industrial plant roofing projects.
The Phase II Expansion Project of Asia Pulp & Paper (Shandong) Co., Ltd., for its household paper products, is located in Rizhao Economic Development Zone. It is a key industrial expansion project of the province and city, with a total investment of RMB 1.2 billion and a total construction area of approximately 92,000 square meters. The project mainly involves the construction of a new paper-making plant, a deep processing workshop, an intelligent automated warehouse, and supporting public and environmental protection facilities. It will also build six new high-end household paper production lines. After completion, the company's total household paper production capacity will reach 300,000 tons/year, with an annual increase in output value of over RMB 2.2 billion. This will further strengthen the regional pulp and paper industry cluster and bring significant economic and social benefits.
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.
On January 27, 2026, the signing ceremony of the annual strategic agreement between Canlon and Central Asia Canlon (CCA) was successfully held in the Polymer Industrial Park, marking the official start of a new cycle of cooperation between the two parties and further enhancing Canlon's brand influence in Central Asia. In the future, Canlon Group will continue to uphold the spirit of innovation, cultivate the Central Asian market, and make the brand influence of "International Canlon" stronger and stronger, contributing more "Canlon power" to the global waterproofing industry!
