Choosing the Right Waterproofing System for Your Parking Facility.
8/5/2024. Written By Joshua D. Bennett.
Parking facilities face a constant barrage of wear and tear. From vehicular traffic and harsh weather conditions to chemical spills and the natural aging process, protecting your structure from water damage is crucial. Waterproofing is not a one-size-fits-all solution, so understanding the different methods and their respective strengths and weaknesses is key to making the right choice for your parking facility. Let's delve into the most common options:

1. Liquid Membranes:
Liquid membranes offer a seamless, flexible waterproofing barrier that adheres to various substrates. They are typically spray- or roller-applied, making them ideal for complex surfaces and intricate details.
Pros:
Seamless: Eliminates risk of leaks at joints or seams.
Flexibility: Accommodates structural movements and thermal expansion/contraction.
Versatility: Suitable for various substrates, including concrete, metal, and wood.
Ease of application: Can be applied quickly and efficiently with minimal disruption.
Cons:
Weather dependence: Application can be affected by rain, humidity, and temperature.
Cure time: Requires specific drying times before traffic or further construction can proceed.
Popular brands and products:
BASF MasterSeal Traffic Systems: Offers a range of liquid-applied waterproofing solutions for vehicular and pedestrian traffic areas.
Sika Sikalastic range: Provides various liquid membranes for different applications and performance requirements.
2. Sheet Membranes:
Sheet membranes are prefabricated rolls of waterproofing material that are applied to the substrate using adhesives or mechanical fasteners. They offer excellent durability and resistance to punctures and tears.
Pros:
Durability: Highly resistant to punctures, tears, and abrasion.
Fast installation: Can be installed quickly with minimal downtime.
Variety of materials: Available in various materials, including PVC, TPO, and EPDM, to suit specific needs.
Cons:
Seams: Potential for leaks at seams if not properly sealed.
Limited flexibility: May not be suitable for complex geometries or areas with high movement.
Popular brands and products:
Carlisle SynTec Systems: Offers a wide range of sheet membrane solutions for roofing and waterproofing applications.
Firestone Building Products: Provides various EPDM and TPO sheet membranes for commercial roofing and waterproofing.
3. Cementitious Coatings:
Cementitious coatings are rigid, mineral-based waterproofing solutions that are applied as a slurry or paste. They form a hard, durable layer that provides excellent protection against water penetration and chemical attack.
Pros:
Durability: Highly resistant to abrasion, chemicals, and UV radiation.
Breathability: Allows water vapor to escape, preventing moisture buildup.
Cost-effective: Generally, more affordable than liquid or sheet membranes.
Cons:
Limited flexibility: Susceptible to cracking under movement or stress.
Surface preparation: Requires meticulous surface preparation for proper adhesion.
Popular brands and products:
Kryton Krystol Internal Membrane (KIM): A crystalline waterproofing admixture that integrates into concrete, providing permanent protection.
Xypex Concentrate: A cementitious capillary waterproofing slurry that reacts with concrete to form a crystalline barrier.
Choosing the Right System:
Several factors influence the selection of a suitable waterproofing system for your parking facility:
Budget: Cementitious coatings are generally the most cost-effective option, followed by liquid membranes and then sheet membranes.
Performance requirements: Consider factors like traffic volume, exposure to chemicals, and desired lifespan.
Substrate type: Choose a system compatible with the existing substrate of your parking structure.
Complexity of the structure: For complex geometries or intricate details, liquid membranes offer greater flexibility.
Installation time: Sheet membranes typically offer the fastest installation time.
Protecting your parking facility with a reliable waterproofing system is an investment that pays off in the long run. By understanding the various options available and their respective pros and cons, you can make an informed decision that ensures the longevity and functionality of your structure.
