Mount Qomolangma Cultural Park Project

Background

Located in Shigatse City, Tibet, the Mount Qomolangma Cultural and Creative Industrial Park is China’s highest-altitude cultural park and serves as a key showcase for Tibetan culture. With a total land area of nearly 10,000 mu, the park underwent a comprehensive transformation and opened around July 2022. As a key project for the Tibet Autonomous Region, construction faced extreme environmental challenges including high altitude, intense UV radiation, large diurnal temperature variations, and fragile ecology. The waterproofing of features like the artificial lake and plaza systems demanded high material durability, construction precision, and environmental performance.

Solution

The roof and underground works primarily used KINJOYA FM PLAIN SBS waterproofing membrane. For the high-altitude, intense UV environment, the membrane used a 3mm-thick high-density carrier and a modified asphalt formulation with enhanced weather resistance. Third-party tests showed UV aging performance exceeding national standards by 30%. To handle diurnal temperature variations of up to 25°C, the membrane’s low-temperature flexibility reaches -30°C. For the artificial lake, a composite system using the SBS membrane and bentonite waterproofing blanket was used. Joints were heat-welded with a minimum 10mm seam width. The plaza used a three-layer system: concrete base + SBS membrane + rigid protection layer. An innovative “segmented preheating, stepped overlapping” technique was developed to solve adhesion issues under low-temperature, high-altitude conditions. Construction waste was 100% recycled, and the process was solvent-free, complying with Tibet’s environmental protection regulations.

Outcomes

Two years after completion, the project has withstood extreme conditions including -28°C cold, 8-grade winds, and intense UV radiation. The roof and underground structures are leak-free, and the artificial lake water level remains stable. The SBS membrane surface shows no cracking or blistering, with over 90% tensile strength retention at seams. The plaza surface has endured heavy foot traffic without damage. The project’s success established a replicable technical standard for waterproofing large-scale cultural tourism projects at high altitudes and was awarded “Green Building Demonstration Project of the Tibet Autonomous Region.”
