The Challenge: Aesthetic, Durable and Easy-Care Pool Liners

Overlap welding is the traditional standard for joining pool liners. However, this process leaves visible welding seams that are difficult to clean on the pool floor and detract from the appearance of the pool. Butt welding, on the other hand, creates almost invisible seams – ideal for modern pools where design, comfort and easy cleaning play a key role.

The Solution: Innovative Welding Technologies

Modern welding processes have revolutionized the installation of pool liners. In our expertise, Leister Product Manager Silvan Horand presents two central welding methods for pool construction:

  • Overlap welding: fast and efficient, but with visible seams.
  • Butt welding with seam tape: ensures an aesthetically pleasing, seamless appearance – perfect for printed or textured pool liners.

Find out which welding method is best for your application and how semi-automatic welding machines mean greater precision and less labor.
