Kerakoll Aquastop Fabric Anti-Cracking Waterproof Membrane 30m Roll

Product Description: Aquastop Fabric - Polyethylene Vapor Barrier Waterproofing Membrane

Aquastop Fabric is a high-performance, polyethylene-based waterproofing membrane designed to protect damp and high-humidity environments. Coated on both sides with high-adhesion polypropylene fabric, this vapor barrier is ideal for use under ceramic tiles, porcelain, mosaics, and stone materials. It is specially formulated for environments with high vapor presence, such as showers, bathrooms, saunas, and swimming pools. Aquastop Fabric serves as an anti-cracking, waterproofing solution in areas with moderate stress, ensuring long-lasting protection against water vapor and chemical aggression.

Key Features:

• Waterproof & Vapor Barrier: Provides complete protection against water and vapor in damp or highly humid environments.
• High Adhesion: Designed for use with gel adhesives from the H40 range, creating a durable bond that withstands alkaline conditions and chemical attacks.
• Ultra-Thin & Flexible: Despite its very low thickness, Aquastop Fabric offers excellent tear resistance and high elasticity to accommodate expansion and contraction.
• Quick Installation: Reduces on-site working times by allowing for immediate foot traffic and tile installation with no waiting required after bonding.
• Anti-Fracture Protection: Its high elasticity prevents cracks and reduces stress, providing long-lasting durability.

Applications:

• Waterproofing and vapor barrier for indoor and outdoor environments, including swimming pools, showers, kitchens, bathrooms, saunas, Turkish baths, balconies, terraces, and flat roofs.
• Ideal for walls and floors before the installation of ceramic tiles, natural stone, or mosaic coatings.
• Suitable for use on a variety of substrates such as screeds, mineral plasters, cured concrete, plasterboard, wood, and fiber-cement panels.

Technical Data:

• Material: Polyethylene (PE) core with polypropylene (PP) fabric on both sides
• Thickness: Approximately 0.3 mm
• Vapor Barrier Resistance: μ > 300,000 (equivalent to an Sd diffusion layer of 122 m)
• Alkali & Chemical Resistant: Designed to withstand harsh environments
• Elasticity: High resistance to tearing and expansion
• Foot Traffic: Withstands foot traffic immediately after application

Recommended Substrates:

• Screeds, mineral plasters, cured concrete, and plasterboard
• Existing ceramic, marble, or natural stone flooring
• Fiber-cement and gypsum fiber panels

Aquastop Fabric is a versatile solution for waterproofing damp areas, providing a reliable vapor barrier that protects construction elements from damage due to moisture and water vapor. It’s the perfect choice for ensuring the long-term durability of tiles and coatings in high-stress environments.
