Insutech CF1
Insutech CF1
Insutech CF1 system is a specialized, integrated engineering solution designed for the waterproofing of Concrete Retaining Walls and underground vertical structures.
The CF1 System is characterized by its high adhesion to vertical surfaces and resistance to lateral soil pressure:
Concrete Wall Surface: Must be clean, smooth, and free from any tie-rod holes or protrusions.
Insucoat Primer: A high-penetration bituminous primer that prepares the substrate and ensures a monolithic bond between the wall and the membrane.
Vertical Bitumen Membrane (Insuultra / Insuprene): A 4mm thick, polymer-modified bitumen membrane (APP or SBS) torch-applied vertically with a minimum overlap of 10 cm.
Protection Board: A 4mm thick, high-density bituminous board fixed over the membrane to safeguard it from mechanical damage during soil backfilling or stone placement.
Consultants prioritize the CF1 system in the following structural scenarios:
Basement Walls: To prevent "weeping" or dampness inside underground parking garages and storage facilities.
Underground Water Tanks: Applied as an external layer to protect the tank structure from external groundwater and soil salts.
Retaining Walls: In areas with high irrigation water levels or heavy seasonal rainfall.
Integrated Raft Connection: Used in conjunction with the IF2 system (Raft Waterproofing) to ensure a continuous "waterproofing envelope" from the base to the sidewalk level.
Vertical Stability: The membranes are formulated to resist sagging or sliding during application, even in high ambient temperatures.
Mechanical Resistance: Provides a durable shield against Lateral Earth Pressure and potential damage from backfill materials.
Detailing Ease: Simplifies technical detailing at corners (Internal/External), pipe penetrations, and joints.
Certified Compliance: Fully compliant with the 2026 Egyptian Code and international ASTM/EN waterproofing standards.
