Sika - Sikadur Combiflex SG-20 M expansion joint sealing tape

Sealing tape for expansion and moving joints. It is waterproof, flexible, made of modified, flexible polyolefins (FPO) with increased adhesion to the substrate. The tape on one side has a red stripe in the center for easy installation.

Features

• increased traction
• very high flexibility
• good chemical resistance
• good aging resistance
• resistance to UV radiation
• root resistance
• preservation of properties in a wide temperature range
• does not contain plasticizer in
• hot air welded
• can be used in contact with drinking water
• is part of the Sikadur Combiflex SG System

Application

The tape is used to seal gaps, gaps and scratches in many types of structures, including tunnels and culverts, wastewater treatment plants, hydropower plants, underground structures, as well as water tanks (including drinking water). Used for sealing expansion and moving gaps, construction joints, pipe penetrations, cracks and structures with expected uneven settlement.
