PVC liners are usually welded together using heat. The PVC adhesive is intended for minor repairs and shorter, straight joints. EPDM liners made of rubber, on the other hand, are glued together. For the OaseFol EPDM liner we offer you a pond construction kit with many useful aids for laying the liner. The UniFix + universal adhesive is suitable for minor work and repairs on all types of liner. It bonds particularly well, for example, a stone liner at the edge of the pond with PVC and rubber sheeting. Among other things, mounting foam stabilises loose edging stones and other design elements around the pond. Tip: always design the edge of the pond at the same height to create an effective capillary barrier.
