A-Type Deep Plastic Drainage Belt | Shengyuan Wick Drain

Jianhu Shengyuan Soft Base Material Co., Ltd. produces this board at its plant in Jianhu, Jiangsu, as a member of the China Geosynthetics Engineering Association. The design targets deep insertion: a rigid core holds the drainage channel open along the full board length, while the filter jacket keeps its position as the board passes through several soft soil strata, so filtration stays steady and the passage does not collapse under load at depth.

Production capacity. Eight plastic drainage board lines run at a combined 600,000 meters per day, and integral hot-melt board lines add a further 500,000 meters per day. Bulk orders for large sites are scheduled from the same base in Jianhu.

Installation backup. Supply does not stop at the factory gate. A fleet of 50 drainage board and sand-wick rigs, 33 deep mixing pile machines and three one-metre stone column rigs can be moved to site, so board and installation come from one team.

Project record. The board has served airport, port and reclamation works, including Shenzhen Airport, Shanghai Pudong Airport Phase III, Ningbo Beilun Port Phase III, the Hangzhou Bay Bridge approach lines, Yangshan container terminal land formation and deep foundation works, Huanghua Port reclamation phases, and overseas reclamation at Sihanoukville in Cambodia and Pasay in the Philippines.

Every board is made in our own factory, and export enquiries are welcome.
