High-Efficiency Drainage Board Production Line

Product Overview

The High Efficiency Drainage Board Production Line is an advanced manufacturing system engineered to produce high-performance drainage boards for civil engineering, construction, and environmental protection projects. Integrating extrusion, embossing, and geotextile lamination technologies, this line delivers a continuous production workflow capable of manufacturing dimpled drainage boards with exceptional water flow capacity and structural durability. With a maximum production speed of 8 meters per minute and daily output of 2,000 square meters, it meets the demands of large-scale infrastructure projects requiring efficient water management solutions. The line produces boards with a compressive strength exceeding 15,000 lbs/sqft, ensuring long-term performance in heavy-load environments such as underground parking lots and green roof systems.

Product Features

Superior Water Flow Capacity

Equipped with precision-engineered dimple forming rollers, the line produces drainage boards with a water flow rate of 18 gal/min/ft of width, significantly reducing hydrostatic pressure behind retaining walls and building foundations. The 10mm standard dimple height can be adjusted to 5–15mm based on project requirements.

Multi-Layer Composite Structure

The production process bonds a high-strength polypropylene core with non-woven geotextile fabrics on both sides, enhancing filtration efficiency while preventing soil particle migration. This composite structure achieves a filtration rating of 90% particle retention for particles ≥0.075mm.

Energy-Efficient Operation

Integrated with a variable frequency drive (VFD) system and heat recovery technology, the line reduces energy consumption by 22% compared to conventional models. The main extruder (75kW) operates at optimal efficiency through intelligent temperature control (180–220°C).

Continuous Quality Monitoring

An online thickness gauge and ultrasonic flaw detector inspect every linear meter of production, ensuring dimensional tolerance within ±0.2mm and detecting material defects with 99.8% accuracy, minimizing post-production waste.

Applications

This high-efficiency production line serves diverse infrastructure needs:

Civil Engineering: Subsurface drainage for roadways, railways, and tunnel systems.

Building Construction: Foundation waterproofing and basement drainage systems.

Green Building: Vegetated roof drainage and vertical garden water management.

Environmental Engineering: Landfill leachate collection and contaminated site remediation.

FAQ

What materials are used in production?

The line processes virgin polypropylene (PP) granules and recycled PP (up to 30% content) with melt flow index (MFI) of 2–5 g/10min (230°C/2.16kg) for optimal forming.

What is the standard board size?

Standard width ranges from 1m to 3m with length customizable up to 30m per roll. Special widths up to 4m are available with custom die configurations.

How long is the production cycle for a full order?

For a typical order of 10,000 square meters, the line completes production in 5 working days including quality inspection.

Does the line meet international standards?

Yes, produced drainage boards comply with ASTM D5101 and EN 13598 standards, with CE certification available for European markets.
