Wavin Ekoplastik PPR fittings

In construction, expansion joints mean deliberately created gaps between two buildings or structural elements. Separated parts work more efficiently and have freedom of deformation. However, expansion joints require filling. A special building material is used for this task (and not only for this purpose) - expansion tape. Made of polyethylene foam, it is strong and resistant to chemicals used in construction, and at the same time flexible, soft, light and easy to use.
