Direct supply of high-torque, smart-controlled extrusion lines engineered for the most rigorous structural and environmental waterproofing requirements in Switzerland.
An authoritative industry whitepaper outlining performance standards, localized configurations, and global supply efficiency.
In Switzerland, structural waterproofing is governed by demanding standards such as the SIA 272 guidelines (Waterproofing of Buildings below Ground Level) and SIA 271 (Waterproofing of Roofs). The Swiss alpine climate presents unique challenges: extreme temperature fluctuations, high hydrostatic pressure in valleys, and shifting mountain rocks in major tunnels like the Gotthard Base Tunnel.
Underground railway structures, road tunnels, and civil infrastructure demand membrane systems with a design life of over 100 years. This has led to a massive shift from traditional bituminous sheets to advanced thermoplastic polymer sheets:
Globally, the polymer waterproofing membrane market is experiencing a projected compound annual growth rate (CAGR) of over 5.8%. The transition from energy-heavy bituminous melting to heat-welded synthetic sheets represents a milestone in green construction. Modern extrusion lines are now complex co-extrusion setups capable of producing 3-layer or 5-layer sheets, incorporating internal reinforcement grids (such as glass fiber or polyester fleece) to guarantee dimensional stability under mechanical stress.
While Switzerland remains the center of structural engineering precision, China GWELL Machinery bridges the gap by offering unparalleled factory efficiency and manufacturing scale. By operating three advanced manufacturing bases covering over 866,000 square meters, GWELL optimizes the entire mechanical value chain:

Direct technical answers addressing the procurement, engineering, and maintenance of polymer waterproofing sheet extrusion lines.
TPO (Thermoplastic Polyolefin) lines require precise temperature control and dynamic mixing screw profiles due to TPO's narrow processing window and tendency to shear-degrade. PVC lines require specialized anti-corrosive treatments (such as chrome-plated die heads and special screw alloys) to prevent hydrochloric acid degradation. HDPE lines prioritize high-output, deep-channel melt pumps and longer cooling/calendering configurations to handle crystallization and prevent thermal stress buckling in heavy-gauge geomembranes.
SIA 272 demands absolute uniform thickness and specific mechanical tensile elongation properties. Gwell machines integrate automated T-dies connected directly to dynamic radiometric thickness control loops. This automated process measures and adjusts the die lips in real-time, achieving thickness variation tolerances below ±1%, ensuring the structural integrity of the co-extruded signal layer for leak detection.
The three-roll or four-roll calender system controls the cooling rate, surface texturing, and sheet embossing. For civil engineering membranes, texturing (embossing) is essential to provide anti-slip characteristics on steep tunnel walls and roofs. Gwell uses high-rigidity calender rolls with internal spiral water circulation, maintaining precise surface temperature uniformity within ±0.5°C to avoid internal stress accumulation.
Yes. Gwell co-extrusion lines are routinely configured with multi-manifold structures. This layout allows for a 3-layer configuration where the core layer comprises up to 50% to 70% recycled materials, while the top and bottom outer layers utilize virgin polymer layers to maintain essential physical resistance and weathering qualities.
Gwell utilizes energy-efficient components, including electromagnetic heaters, permanent magnet synchronous motors (PMSM), and advanced Siemens PLC power management systems. This combination reduces net power consumption by 15% to 25% compared to traditional single-screw or low-efficiency heating setups.
We provide remote diagnostics coupled with on-site engineering services. In critical sectors like Europe, Gwell works with local technical agents to execute mechanical installation, PLC calibration, and staff commissioning training. Additionally, all machinery components use global brands (e.g., ABB, Siemens, Omron) to ensure easy local parts availability.
Our lines can feature dedicated laminating modules designed to incorporate polyester fleece, glass fiber grids, or aluminum foils. This integration occurs directly at the calender roll nip point, creating a unified compound sheet without requiring secondary processing steps.
Standard engineering, assembly, and testing of a custom waterproofing sheet line take between 120 and 150 days. All lines come with a comprehensive 12-month mechanical warranty, lifetime remote support, and pre-shipment FAT (Factory Acceptance Testing) validation.
