Coastal structures, exposed to saltwater and high humidity, require polymer waterproof membranes with superior corrosion resistance. Weifang Luyang’s modified bitumen membranes, blended with corrosion inhibitors, protect concrete piers and seawalls from chloride-induced deterioration. A port expansion in Indonesia’s Sunda Strait utilized our membranes to waterproof storage tanks, preventing leaks that could contaminate marine ecosystems. The membranes’ self-healing properties, activated by heat, sealed minor punctures automatically, reducing maintenance frequency. Our import/export authority ensures timely delivery of bulk orders to remote project sites.
