Sikadur-Combiflex® SG System

High performance joint sealing system

The Sikadur-Combiflex® SG System is a versatile, high performance, joint and crack sealing system for construction joints, movement (expansion) joints, connection joints or cracks. The system allows variable and high levels of movement in one or more directions, whilst maintaining a watertight seal.  
The Sikadur-Combiflex® SG System consists of a waterproofing tape based on modified flexible Polyolefin (FPO) with advanced adhesion properties and available in 1,0 mm and 2,0 mm thicknesses. For bonding the tape, a range of different special Sikadur® epoxy adhesives for use in different types of applications and conditions are available.
