Segmented Floating Cover System

Installation and Adaptability Made Easy

When deployed, LET’s segmented floating cover system discs distribute themselves across the water surface to easily accommodate any basin equipment, piping, or water fluctuations. This system is exceptionally quick and easy to install, with self-leveling and self-positioning discs that can be installed in both full and empty basins. Once the floating segmented cover has installed itself across the water surface, the system then adjusts for any irregularities, delivering up to 99% surface coverage.
