• Excellent mechanical properties.
• High resistance to impact, puncture, and tear.
• Cold applied: Easy and fast application without torching, increasing site safety.
• Self-adhering: Easy peel and stick method without the need for complicated tools.
• Self-healing: The polymerized bitumen compound has self-sealing property against minor punctures.
• Excellent chemical resistance: Withstands corrosive conditions of ground water, chlorides, and sulphates in soil.

iStik 250R is a 2.1mm thick high-performance self-adhesive protection membrane manufactured with a blend of high grade SBS polymers, selected additives, and bitumen. The polymer-modified bitumen compound is laminated onto a tough, rot-proof Polyester fleece. Due to the high mechanical and puncture resistant properties of the fleece, iStik 250R is ideally suitable for application as protection membrane for waterproofing membranes and coatings in below ground concrete structures. Being highly flexible, the protection membrane can be easily applied over curved profiles and other critical details. iStick 250R conforms to the requirements of BS 8102 standards

Used as protection membrane on waterproofing membranes and coatings applied to:

• Underpasses and tunnels
• Concrete basements and foundations, rafts and retaining walls
• Manholes
• Bridge Piers and Viaducts
• Other buried concrete structures
• As DPC layer under block work for mitigating rising dampness
• Also can be used as membrane cum protection board for non- critical structures
