Applications and Best-Fit Scenarios
Swimming pools and water features - chlorine-resistant Aquastop Nanoflex for permanent submersion
Terraces and balconies - breathable Aquastop Green handles thermal movement and ponding water
Bathroom wet areas - seamless membrane protection before tile installation
Renovation over existing tiles - apply Aquastop directly on old ceramic without demolition
Green building projects - GreenBuilding certified products for LEED and sustainability requirements
Cracked substrates - Aquastop Green anti-cracking membrane bridges substrate defects
How to Choose the Right Kerakoll Waterproofing System
Evaluate substrate breathability needs - breathable membranes prevent trapped moisture on cementitious substrates
Check chemical exposure - pools and water features need chlorine-resistant Aquastop Nanoflex
Consider substrate condition - cracked supports require Aquastop Green anti-cracking formula
Identify renovation scenarios - existing ceramic coverings can be waterproofed directly without removal
Match to sustainability goals - GreenBuilding certification supports green building documentation
Select component system - single-component for convenience, two-component for maximum performance
Assess vapor pressure risk - substrates with potential vapor pressure need specialized treatment
Common Mistakes to Avoid
- Using non-breathable membranes on cementitious substrates - trapped moisture causes delamination and failure
- Skipping anti-cracking treatment on compromised supports - substrate cracks telegraph through standard membranes
- Applying over damp substrates without vapor management - moisture must be addressed before waterproofing
- Insufficient overlap at sheet joints - membrane continuity is essential for watertight performance
- Ignoring alkaline substrate conditions - pools and new concrete need anti-alkali formulations

Frequently Asked Questions
Aquastop membranes are mineral-based and allow water vapor to pass through while blocking liquid water. This prevents moisture from becoming trapped between the membrane and substrate, which causes delamination, efflorescence, and premature failure in conventional non-breathable systems.
Yes. Aquastop membranes can be applied directly over existing dimensionally stable ceramic and marble tiles, eliminating the need for costly and time-consuming demolition. This is particularly valuable for renovation projects where minimizing disruption is important.
Aquastop membranes are recyclable as inert material at end of life. Unlike petroleum-based waterproofing that becomes construction waste, Kerakoll membranes can be processed and recycled, supporting circular economy principles and reducing landfill impact.
Aquastop Nanoflex is the recommended choice for swimming pools. It is anti-alkali and chlorine-resistant, handles permanent water submersion, and bonds effectively to pool substrates. The breathable formula is compatible with typical pool construction methods.
Aquastop Green is specifically formulated as an anti-cracking waterproof membrane. It bridges existing substrate cracks and accommodates future movement without transferring cracks to the tile surface. This makes it suitable for imperfectly cured supports or substrates with existing damage.
Aquastop Nanoflex is a single-component membrane with anti-alkali and chlorine resistance, ideal for pools and chemically demanding environments. Aquastop Flex is a two-component system offering maximum flexibility and adhesion for high-performance applications on terraces and balconies.
Aquastop products carry GreenBuilding ideal certification with documented low VOC emissions and low CO2 manufacturing footprint. Technical data sheets provide the environmental credentials required for LEED and other green building certification submissions.
Aquastop Green is designed for substrates that might contain vapor pressure from imperfect curing or rising damp conditions. The breathable membrane allows vapor to escape while maintaining waterproof protection against liquid water intrusion.
Breathable Membrane Technology
Conventional waterproofing membranes create a vapor barrier that traps moisture between the membrane and substrate. This trapped moisture causes efflorescence, delamination, and premature system failure. Kerakoll Aquastop membranes are breathable - they block liquid water while allowing water vapor to escape. This critical difference ensures long-term performance on cementitious substrates.
Aquastop Nanoflex Single-Component
Aquastop Nanoflex is a certified, eco-friendly, breathable mineral membrane for flexible waterproofing. The single-component formula simplifies application while delivering anti-alkali and chlorine resistance for demanding environments. Low CO2 emissions and very low VOC content make it the sustainable choice for green building projects.
Aquastop Flex Two-Component System
For maximum performance on terraces, balconies, and swimming pools, Aquastop Flex delivers two-component waterproofing with exceptional adhesion and flexibility. The system creates water-resistant barriers before ceramic tile installation, even over existing coverings, eliminating the need for costly demolition work.
Aquastop Green Anti-Cracking Formula
Substrates with existing cracks, imperfect curing, or potential vapor pressure require specialized treatment. Aquastop Green is an anti-cracking waterproof membrane that bridges substrate defects and accommodates movement. It creates watertight protection even on compromised supports that would defeat standard membranes.
End-of-Life Environmental Responsibility
Sustainability extends beyond installation to end-of-life disposal. Aquastop membranes are recyclable as inert material, unlike petroleum-based alternatives that become permanent construction waste. This circular economy approach reflects Kerakoll commitment to genuine environmental responsibility throughout the product lifecycle.
Renovation Without Demolition
Bathroom and kitchen renovations traditionally require demolishing existing tile coverings before waterproofing. Aquastop membranes can be applied directly over existing ceramic and marble tiles, dramatically reducing renovation time, cost, and construction waste. This overlay capability transforms the economics of waterproofing upgrades.
