Product Specification:
It can be produced according to different requirements of customers.
Product Applications:
Foundation Drainage – Drains water, blocks capillary rise, shortens drainage paths, and extends road lifespan by allowing finer sub-base materials.
Sub-Base Stabilization – Isolates fine materials, restricts lateral movement, and reinforces foundations with high tensile strength.
Surface Drainage – Collects moisture beneath pavement, prevents infiltration, improves drainage efficiency, and enhances concrete curing.
Frost Protection – Reduces frost heave by blocking capillary water, replaces frost-prone materials, and minimizes spring thaw damage.
