Leno compound base mats are woven reinforcement fabrics widely used as base layers in waterproofing membranes (SBS/APP modified bitumen) and other construction-related products. Their performance depends largely on the weight, strength, and fiber composition selected for a given application.
Key Specifications
Material Composition
Usually made from fiberglass or a cotton–fiberglass blend, providing high strength, dimensional stability, and resistance to heat and chemical exposure.
Unit Weight
Available in a broad range—from 70 g/m² to 180 g/m²—with lighter mats used for flexible membranes and heavier mats for high-strength applications.
Tensile Strength
Performance varies by weight grade:
-
Light mats (≈70–90 g/m²): ~300–400 N/5 cm (longitudinal), 100–200 N/5 cm (transversal)
-
Heavy mats (≈180 g/m²): up to ~1000 N/5 cm in both directions
Moisture Content: ≤ 0.5%
Shrinkage at 200°C: ≤ 0.5%
Roll Dimensions: Typically 1 m wide, 1000–1400 m long.
Customization: Weight, tensile strength, width, and roll length can all be tailored for specific performance requirements.
Primary Applications
Waterproofing Membranes
Used as reinforcement layers in SBS/APP modified bitumen membranes, providing mechanical strength, dimensional stability, and improved waterproofing durability.
Construction & Roofing
Acts as a structural fabric in roofing sheets and construction membranes, boosting tear resistance and long-term mechanical performance.
Backing & Decoupling Layers
Serves as the backing fabric for dimpled sheets, nonwoven mats, and similar multilayer construction products.
Composite Laminates
Used as reinforcement for technical laminates and composite materials requiring added strength and stability.
Packaging & Industrial Papers
Enhances tear resistance and structure in specialty papers and industrial packaging.
Agriculture & Tarpaulins
Reinforces tarpaulin systems, livestock curtains, and other flexible agricultural fabrics.
Conclusion
Leno compound base mats are engineered to balance flexibility and mechanical reinforcement through variations in weight and tensile strength. Their primary value lies in enhancing durability, stability, and waterproofing performance in roofing membranes and construction materials—while also offering reliable reinforcement for packaging, composites, and agricultural textiles.
