Saudi Arabia Jizan Project Case

Initiated in 2013, the Jazan Economic City (JEC) is a flagship development by the Saudi Arabian government. Located approximately 80 kilometers from Jazan city, the planned city spans 103 square kilometers with an 11-kilometer coastline and a total investment of USD 25 billion. As a key project under China's Belt and Road Initiative in the Middle East, JEC integrates oil refining, power generation, shipping, administrative and residential zones. It is planned to host a refinery with a daily capacity of 400,000 barrels of standard oil, along with a supporting power plant, making it a pivotal driver of economic growth along Saudi Arabia’s Red Sea coast.

This project utilizes high-strength, UV-resistant geotextile tubes filled with dredged sand, which are stacked in layers to form perimeter dikes. These structures are further reinforced with rubble stone masonry to provide permanent coastal protection. The reclaimed land area is then backfilled with the dredged sand. The geotextile material must be able to withstand the following site conditions: 10-12 hours of daily UV exposure and surface temperatures ranging from 50°C to 80°C.
The properties that geotube bags need to have:

• High tensile strength
• Excellent elongation performance
• Superior anti-aging capability

In 2017, our company supplied geosynthetic materials to CHEC for this project:

• Material: UV-resistant woven geotextile for geo tube fabrication
• Specification: 200 g/m²
• Tensile Strength: ≥ 44 KN/m (MD/CD)
• Quantity Supplied: Approx. 1,300,000 square meters

Throughout the project, all mechanical properties of our woven geo tubes met the design requirements. The materials successfully withstood the harsh climate conditions at the site and received high recognition from both China Harbour Engineering Company and the project owner.
