When it comes to tensile structures, industrial covers, and biogas balloons, leaks are the most common and costly problem. According to industry observations, approximately 70% of leaks occur due to poor welding rather than fabric quality. This often-overlooked statistic highlights why precision welding is as important as the fabric itself.

At Lucky-Tech Membranes, we combine European-quality PVC fabrics with high-precision German welding technology to ensure every seam is airtight, durable, and reliable. As the exclusive partner of Sioen Industries (Belgium), we guarantee long-lasting performance for every tensile project.

Why Poor Welding Causes Leaks

Even the strongest PVC fabric cannot compensate for inadequate welding.

Common issues include:
• Incomplete or uneven seam bonding
• Air pockets or micro-gaps in the weld
• Weak spots at corners or edges
• Thermal stress cracks due to improper heat control


These defects create leak points that compromise the structure, leading to >maintenance costs, water damage, or gas leakage in biogas applications.

High frequency & seamless Welding Reduces Risk

Proper welding ensures that every joint is airtight and consistent.
At Lucky-Tech, we use German-engineered high-frequency & seamless welding machines,

which provide:
• Uniform weld thickness
• Seamless, durable joints
• Resistance to pressure, wind, and temperature changes


Tip: Always ask your supplier about the type of welding technology used and their quality verification process.

Training and Experience Matter

Even the best machines require skilled operators. Poorly trained technicians can produce weak or inconsistent welds, increasing the risk of leaks.

Lucky-Tech Membranes employs highly trained professionals with years of experience in handling European PVC fabrics. Every weld is inspected to meet international quality standards.

Fabric Quality Alone Isn’t Enough

Many assume that strong PVC fabric is sufficient, but without high-frequency and seamless welding, leaks are inevitable.

Combining premium European fabric from Sioen Industries (Belgium) with expert welding techniques ensures that both material and workmanship work together for a leak-proof structure.

The Lucky-Tech Advantage

By addressing the root cause of 70% of leaks — poor welding

Lucky-Tech delivers:
• Durable tensile structures and biogas balloons
• Long-term performance with minimal maintenance
• Reliable, airtight seams for water and gas containment
• Peace of mind for engineers, architects, and project owners

Conclusion

Leaks don’t just damage structures — they impact project timelines, costs, and safety. Choosing a partner that combines European-quality PVC fabrics with high-frequency and seamless welding is the key to leak-free, long-lasting tensile structures.

At Lucky-Tech Membranes, we ensure that every weld is perfect, every seam is secure, and every project stands the test of time.
