Vanke is a renowned in China for its real estate developments, including shopping centers, residential towers, ski resorts, and more. Many of the world's top architectural firms are involved in these projects.


One of the signature elements of the new Vanke Nantong Fei Cui Xin Lake - the 25,000m2 artificial lake - utilizes a Bentofix® X2 polyethylene coated geosynthetic clay liner (GCL) for superior sealing performance. The site is in the lush, green countryside near Nancheng. Fei Cui Xin Lake is the centrepiece of the real estate. The area is home to a unique reshwater jellyfish. With its presence and with a focus on environmental protection in the region, the housing development required significant water resource conservation and cleanliness protections.

Naue’s Bentofix® X2 GCL was specified to provide a high-quality environmental barrier for the artificial lake.

The Bentofix® X series features multi-component GCLs. These needle-punched, reinforced composites combine two durable geotextile outer layers and a uniform core of high-swelling powder sodium bentonite clay, as used in other Bentofix® products; but, with one key difference: an additional polyethylene coating is extruded onto the woven component side.

The coating enhances the material’s internal shear resistance and barrier performance. It guards against desiccation and serves as a root barrier. It also provides protection against any possible effects to the sealing bentonite layer and prevents any bentonite piping due to high hydraulic gradients.

For Fei Cui Xin Lake, a Bentofix® X2 multi-component GCL was precisely what the developer needed to ensure that the community’s new residents would have a clean, idyllic water body to build their lives around. Another interesting part about this project is that the Craspedacusta, which has not been seen in the Yangtze River basin for many years, has extremely high water quality requirements, reappears in the artificial lake.
