KUNEX® puddle flanges are used to seal flat and round earthing strips and pipelines that penetrate building components made of watertight concrete. The puddle flange is made of thermoplastic elastomer (TPE) and is tested and resistant to a wide range of chemical substances. It is simple to install and can be combined with all common pipe materials and diameters making the system a flexible, safe and economical solution. It only requires the ground pipe or earthing strip installed on site to have a smooth, clean and damage-free surface. The system comes ready to install with all the required materials.
