PE 3D Drainage Composite Production Line

What the Tongjia drainage composite line produces

The Tongjia PE 3D drainage composite production line makes a composite geonet by extruding the core structure from polyethylene plastic, with non-woven fabric automatically bonded to both sides in the same production run. The core has one thick vertical rib plus two diagonal ribs on the top and bottom surface, which creates multiple pathways for groundwater to flow away from buried structures. The non-woven fabric layers act as a filter, blocking fine soil particles from entering the drainage core while allowing water to pass through freely.

Buyers know this material by several names depending on the context. Drainage engineers and civil contractors call it a 3D drainage composite, composite geonet, drainage geocomposite, or geonet sandwich. Traders and manufacturers call it PE drainage composite, 3D geonet, non-woven faced geonet, or simply composite drainage mat. If you searched for any of those terms, this is the machine that makes it.

Built for manufacturers who want to make drainage composites in-house

This production line suits companies that want to produce and sell drainage composites rather than import finished panels: geosynthetics manufacturers adding drainage composites to an existing range, non-woven fabric processors who want to move into geo-textiles, and civil contractors or civil works suppliers who currently source finished composites from traders or distributors. The four model sizes give a clear range: the TJ-SWW90 and TJ-SWW135 for mid-scale production (2,500 to 3,000 mm width), and the TJ-SWW150 and TJ-SWW180 for larger footprints and higher throughput (4,000 to 6,000 mm).

Drainage composites vs stone/gravel and plain geonet

Drainage composites with integrated non-woven facing solve two problems that plain geonet and stone drainage cannot:

• Filter function without clogging: The non-woven facing blocks fine soil particles from entering the drainage core, which keeps the core's pore system open over decades instead of clogging with silt. Stone and gravel drainage paths become progressively blocked under load.
• Combined drainage and reinforcement: The ribbed core provides both rapid water discharge AND lateral earth reinforcement in the same layer, reducing the number of material types needed on a foundation or embankment project.
• Lightweight and fast to install: Composite panels are light, roll on-site and unfold into place quickly. Stone and gravel layers require heavy equipment, multiple passes and significant labour time.
• Stable under high load: The non-woven fabric keeps the drainage core from being crushed or distorted by settlement on soft ground, preserving water flow for the design life of the structure.

Industries that use drainage composites in India

Drainage composites made on this line serve India's civil, infrastructure and building construction sector:

• Highway and expressway construction: Pavement and subbase drainage layers under new road construction and highway widening projects.
• Railways and metro rail: Trackbed and embankment drainage under railway and metro projects.
• Building foundations: Sub-slab drainage and waterproofing under residential and commercial building foundations on wet or clay soil.
• Embankment and slope reinforcement: Drainage and lateral confinement on steep slopes, embankment faces and canalbanks.
• Soft ground improvement: Horizontal drainage and reinforcement layers on compressible soil to reduce settlement.
• Retaining structures and abutments: Drainage and reinforcement behind earth walls and bridge abutments.
• Dams and water control: Seepage control and stability layers in earth dams and water-retention structures.
