Sealing profiles, swelling in contact with water. The offer includes homogeneous profiles - smooth swelling profiles, red, with a high swelling index, as well as hybrid profiles - full or hollow, where the outer red part is a material with a high swelling index, and the inner black part is a swelling material.

Features

• water-resistant material
• ready to use immediately after installation
• does not require welding
• universality of use to solve many problems on the construction site
• the offer includes various types of profiles with different cross-sections
• quick and easy application
• application possible on various surfaces

Application

Sealing:

• contact in working conditions
• contact in between tunnel elements
• contact in working in cable channels
• pipes and conduits passing through concrete elements
• element in prefabricated
