CHANGFENG Cement Blanket for Canal Lining
PROJECT OVERVIEW
Location: Central Luzon, Philippines
Application: Irrigation Canal Lining & Seepage Control
Product: CHANGFENG Cement Blanket
Scope: 8,500 m²
1.THE DIFFICULTY
The aged earthen canal had significant bank erosion and water loss, which resulted in:
High Seepage: Before reaching crops, more than 35% of irrigation water was lost.
Logistical Restrictions: Conventional concrete mixers were unavailable due to the remote location.
Time Pressure: Before the monsoon season, repairs have to be finished.
2.THE CHANGFENG SOLUTION
The CHANGFENG Cement Blanket provided a “concrete on a roll” solution that eliminated the need for heavy machinery:
Rapid Laying: Rolled out manually to conform to the canal’s irregular shape.
Easy Hydration: Hardened into a high-strength concrete layer within 24 hours of adding water.
Instant Armor: Created a durable, waterproof surface to prevent erosion and leaks.
3.KEY BENEFITS
Speed: Installation was 10 times faster than traditional poured concrete.
Water Saving: Reduced water seepage by 95%.
Cost-Effective: Minimal labor and zero heavy equipment required.
4.THE OUTCOME
The project was completed ahead of schedule, ensuring a stable water supply for local agriculture with:
Zero Seepage: PVC backing and a 100% waterproof lining.
Low Maintenance: Exceptionally resistant to pesticides, UV rays, and root penetration.
Long Life: Built to last for more than 50 years.
PRODUCTS USED
CHANGFENG Cement Blanket
Rapid Hardening: A flexible geosynthetic filled with concrete that, when hydrated, solidifies into a layer of waterproof concrete.
3D Fiber Matrix: High tensile strength under water flow is ensured and breaking is prevented by internal reinforcement.
Integrated PVC Backing: An impermeable, long-lasting barrier against seepage is provided.
Simplified Logistics: Concrete trucks are replaced with manageable rolls to minimize the site’s footprint.
CHANGFENG: MANUFACTURING TO SERVICE
We manufacture high-performance geosynthetics to solve the world’s toughest engineering challenges. Quality without compromise, from factory to site.
