Tensile structures are visually striking, functional, and versatile. However, improper design can lead to common problems such as ponding (water accumulation) and undesirable curvature, which compromise structural integrity, aesthetics, and longevity.

At Lucky-Tech Membranes, we provide European-quality PVC fabrics in partnership with Sioen Industries (Belgium). Our expertise ensures that every tensile structure is designed and executed with precision, minimizing risks of ponding and deformation.

Correct Slope and Tension

Proper slope is crucial to ensure effective water drainage.
• Insufficient slope can result in water pooling, increasing stress on the fabric.
• Uneven tension causes wrinkles and irregular curvature, weakening the structure.


Tip: During the design phase, calculate slopes carefully and plan tension distribution to prevent static water accumulation.

Strategic Anchor Placement

Anchor points define the shape and stability of the structure. Poorly positioned anchors can create stress concentrations that lead to curvature and sagging. Considerations:
• Use anchors that allow adjustable tensioning
• Position anchors to distribute load evenly across the membrane


Lucky-Tech ensures that anchor planning is optimized for both function and aesthetics, providing a safe, balanced structure.

Fabric Selection and Pre-Stretching

Not all fabrics perform the same under tension. Choosing the right PVC fabric and pre-stretching it correctly reduces sagging and curvature. Tips:
• Select fabrics with high tensile strength and low elongation
• Pre-stretch to minimize post-installation deformation


Lucky-Tech Membranes provides European-quality PVC fabrics that are engineered to retain shape and resist ponding, ensuring a smooth, wrinkle-free surface.

Structural Reinforcement and Geometry

The overall geometry of the tensile structure directly affects water drainage and tension distribution.

• Incorporate curves and folds strategically to guide water flow
• Use reinforced edges and seams to handle localized stress


By combining expert structural design with high-quality materials, Lucky-Tech ensures that the tensile structure remains both functional and visually appealing.

Conclusion

Preventing ponding and curvature starts at the design table, not after installation. By focusing on slope, anchors, fabric selection, and geometry, engineers and architects can create tensile structures that are durable, safe, and beautiful.

With Lucky-Tech Membranes, you get European-quality PVC fabrics, technical expertise, and precision engineering to ensure your tensile projects are long-lasting and problem-free.
