The world's green roofs has a history of 4000 years.  From the ancient castles and temples of the lower Euphrates to the sky gardens of the Babylonian kingdoms, from the ancient city walls of Nanjing in the Ming Dynasty and the ancient Great Wall in Shanxi to the flowers and trees planted on the stone platforms of the Zongmiao temples in Chengde, all show the historical footprints of the development of green roofs.

Modern green roofs in China began to develop in the early 1980s and have been widely valued and adopted with the promotion of green buildings. In view of the actual need for greening in domestic buildings, the JGJ 155-2007 Technical Regulations for Planted Roofing Projects, promulgated in 2007, required the use of root-puncture resistant waterproofing membranes to prevent leakage caused by plant roots puncturing the building's waterproofing layer. Over time, the development and implementation of the "Root Puncture Resistant Waterproofing Membrane for Planted Roofs" National Standard (GB/T 35468-2017) has further promoted the use of root puncture resistant waterproofing rolls on green roof projects.


Root puncture resistance experiments are carried out in experimental chambers for a period of up to two years, with the test pieces of the experimental membrane installed in six experimental chambers, and the final results compared through six sets of repetitions, with each chamber containing several specified joints (four standing corner joints, two bottom edge joints, and one central T-joint) in which the experimental root puncture-resistant membrane is placed underneath the roots under specified conditions. Two additional control boxes without the experimental membrane were set up in order to compare the growth efficiency of the plants throughout the experimental period.

After two years of planting tests, mid-term observations, and final open-box verification, the MBBAC root-puncture resistant waterproofing membrane, MBBAC self-adhesive polymer modified bitumen waterproofing membrane (root resistant type), and MBP-ZZ thermoplastic polyolefin (TPO) root-puncture resistant waterproofing membrane sent by CANLON to the Weifang Quality Inspection Branch of China Building Materials Inspection & Certification Group Suzhou Co Ltd successfully passed the GB/T35468-2017 standard root-puncture resistance test.


Weifang Quality Inspection Branch of China Building Materials Inspection & Certification Group Suzhou Co., Ltd. is the third laboratory in China after Beijing and Guangzhou for root penetration resistance of plants. Previously, CANLON's MBP Pro Pre-applied Waterproofing Membrane, PVC Roofing Membrane and SBS Modified Bitumen Membrane passed the root penetration resistance test conducted by the Beijing Institute of Landscape Architecture, covering both chemical and physical root resistant types, achieving diversity and comprehensiveness in construction methods and application scope, meeting the waterproofing needs of different occasions and providing comprehensive waterproofing protection for the construction of green cities and sponge cities.
