Application

Drykos® PO PVC Joint must be installed internally within the concrete pour, positioning the profile between two successive pours at the joint. The central bulb must be correctly aligned with the movement zone of the joint to allow for the absorption of structural deformations. The lateral fins must be completely embedded in the concrete. The profile should be secured using metal clips or ties to the reinforcement, ensuring stability during the pouring and vibration phases of the concrete. Connections between profiles must be made by heat welding, ensuring the perfect continuity of the waterproofing system.
