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, available in 2.0 mm thickness. Sikadur®-31 CF Normal is used for bonding the tape in different types of applications.
