Discover Gwell's premium industrial machinery designed for advanced solar encap, waterproofing membranes, and high-performance casting lines.
In modern civil engineering, basement waterproofing represents one of the most critical challenges to structural durability. Traditional asphaltic and bitumen-based membranes are increasingly failing to meet the rigorous lifespans demanded by high-profile infrastructure projects, tunnels, and deep-foundation basements. The rise of polymer-based waterproofing solutions—specifically Ethylene Vinyl Acetate (EVA) and modified polyethylene alloys—has revolutionized how factories and waterproofing companies approach moisture barrier design.
EVA waterproof sheets possess unique morphological properties. By copolymerizing ethylene with vinyl acetate, the material achieves a molecular matrix that combines the mechanical toughness of semi-crystalline polyethylene with the elastomeric flexibility of vinyl acetate. Unlike rigid PVC, EVA does not rely on plasticizers, which inevitably migrate over time, leading to embrittlement, stress cracking, and eventual barrier failure. Gwell's custom EVA waterproof sheet extrusion equipment is meticulously engineered to process these high-viscosity, shear-sensitive copolymers, allowing waterproofing manufacturers to produce sheets with optimized tensile strength, outstanding elongation, and unmatched puncture resistance.
For basement waterproofing factories and infrastructure development companies, investing in custom extrusion equipment is not merely a capital upgrade; it is a strategic maneuver to control raw material quality, customize chemical additives (such as UV stabilizers, flame retardants, and root-barrier agents), and dramatically lower the cost per square meter of finished membrane.
The global demand for high-performance waterproofing systems is experiencing a strong compound annual growth rate (CAGR), driven by rapid urbanization, massive public transit projects, and tightening building regulations. Regions prone to high rainfall, coastal rise, or seismic activity are mandating thick, self-healing polymer membranes for all municipal projects.

The extrusion of Ethylene Vinyl Acetate (EVA) requires absolute control over melt temperature, shear rate, and residence time. If the temperature exceeds critical limits, EVA begins to degrade thermally, releasing acetic acid. This acid is highly corrosive to machine steel and ruins the physical properties of the sheet. Gwell’s engineering team has optimized our custom extrusion machinery with key proprietary technologies:
For factories that manufacture pre-applied waterproofing membranes (which adhere physically and chemically to concrete), our lines feature integrated compounding stations. These feed non-woven fabrics, release liners, or adhesive layers directly into the calender nip, creating a composite membrane in a single pass. This dramatically reduces handling steps and lowers operational overhead.
Waterproofing requirements vary widely depending on regional geology, regulatory codes, and construction methods. A factory exporting membranes to North America faces different requirements than one supplying infrastructure projects in East Asia or Western Europe.
North America (ASTM Standards): Focuses heavily on vapor barriers for crawlspaces and commercial foundations. Specifications call for thick sheets (up to 2.0mm or 80 mil) with extreme puncture resistance (ASTM D1709). Gwell’s custom extrusion lines allow manufacturers to easily adjust raw material blends to incorporate metallocene PE or plastomers, yielding high dart-impact resistance.
Western Europe (EN 13967 / DIN 18533): Demands highly reliable, multi-layer co-extruded membranes with signal layers to identify installation damage. Europe’s green building regulations also require minimum recycled content, which requires extrusion screws capable of processing post-consumer recyclate without sacrificing barrier integrity.
Asia-Pacific (High-Speed Rail & Metro Tunnels): Requires exceptionally wide sheets (typically 3 to 4 meters) to reduce the number of welded joints in tunnel arches. Gwell specializes in manufacturing wide-format T-dies up to 4000mm, with automatic winders and inline slitting units that guarantee consistent roll winding tension.

As industrial manufacturing moves toward Industry 4.0, Gwell is leading the development of smart, connected polymer extrusion equipment. The engineering roadmap for our custom EVA waterproofing membrane lines focuses on three core pillars:
By pairing non-contact radiometric or ultrasonic thickness sensors with thermal expansion bolts in the T-die, our systems automatically adjust the local die lip gap. If the sensor detects a thin section, the control computer adjusts the heating power in the corresponding die bolt, expanding or contracting it to regulate plastic flow. This system limits thickness variance to less than 1% across the entire width of the sheet.
To produce high-quality EVA sheets, base polymer resins must be blended with carbon black, antioxidants, UV absorbers, and process stabilizers. Gwell’s lines utilize continuous loss-in-weight gravimetric dosing units to ensure that feed rates remain consistent, even if the bulk density of recycled materials or masterbatches varies during production.
Extruding large quantities of polymer requires significant energy. Gwell utilizes high-efficiency water-cooled AC motors, ceramic heater bands with integrated air cooling, and energy-recovery heat exchangers in the calender tempering loop. These design improvements reduce energy consumption (kWh per ton of product) by up to 20% compared to legacy designs.
