Zhengtai Waterproofing materials company was established in 2001 year with the registered capital of 1 billion , covering area of 60000 square meter .

An EPDM Rubber Waterproofing Membrane is susceptible to damage from both human activities and environmental factors. Human-related damage can occur through wear and tear from cutting and drilling, exposure to chemicals, improper installation, and inadequate maintenance. Common environmental factors that may harm EPDM membranes include ultraviolet (UV) radiation, significant temperature fluctuations, strong winds, excessive rainfall, and increased water pressure.

The wear and tear resulting from cutting and drilling can lead to punctures or tears in the EPDM membrane, making it vulnerable to leaks. Exposure to harsh chemicals can also degrade the integrity of the EPDM Rubber Waterproofing Membrane. Additionally, improper installation can compromise the seams and joints of the membrane, leading to potential damage over time. Insufficient maintenance of the waterproofing membrane can result in severe leaks and further deterioration.

UV radiation can degrade EPDM membranes when they are exposed to sunlight for extended periods. Significant thermal fluctuations can cause material fatigue, which may ultimately damage the membrane over time. Furthermore, strong winds can tear aging EPDM membranes, while heavy rainfall can elevate underground water pressure, contributing to wear and tear on the membrane layer.
