Durable Waterproofing and Coating for High-Traffic Areas
System Solutions for Parking Decks, Parking Garages, and Underground Parking Garages
Parking decks and underground parking garages are exposed to severe mechanical and chemical stresses. Triflex systems provide long-term protection for concrete surfaces and offer durable solutions for upper decks, intermediate decks, and ramps.
Reliable waterproofing and long-lasting protection for parking decks and underground parking garages
Parking decks and underground parking garages are among the most heavily stressed components of a building. Vehicles, weather conditions, and de-icing salts subject them to constant high mechanical and chemical stresses.
Triflex waterproofing and coating systems based on PMMA liquid polymers reliably protect parking areas from moisture, chloride ingress, and mechanical stress. Thanks to their fast curing, new construction and renovation projects can be completed with exceptionally short closure periods.
This is particularly important for parking decks and underground garages:
- Reliable protection against moisture and chlorides
- Dynamic crack bridging during structural movement
- High mechanical load-bearing capacity for vehicular traffic and maneuvering
- Short closure periods for new construction and renovation
- Secure waterproofing of complex details and connections
System solutions for parking garages and underground parking structures. Designed for heavy loads, short construction times, and long-lasting, reliable protection.

The Right Solution for Every Area
Multistory parking garages consist of areas subject to varying levels of stress. Triflex offers specially developed system solutions for top decks, intermediate decks, underground parking garages, as well as ramps and access roads—tailored to mechanical loads, weather conditions, and chemical exposure.
Topdecks
Top decks are particularly exposed to the elements, temperature fluctuations, and de-icing salts. Triflex waterproofing systems provide long-lasting protection for these surfaces and ensure high mechanical strength and long-term watertightness.
The systems are seamless, durable, and specifically designed for heavily used parking areas.
Key features:
- UV- and weather-resistant
- High wear resistance
- Permanent protection against moisture and chlorides
- Suitable for high mechanical loads
- Seamless sealing of details and connections
Mezzanines and underground parking garages
Indoor parking areas are constantly exposed to high mechanical stresses as well as chemical effects from fuels, oils, and de-icing salts. Triflex coating systems reliably protect these areas and ensure durable, slip-resistant, and low-maintenance surfaces for daily use.
Key Properties:
- Chemically resistant to fuels, oils, and de-icing salts
- Slip-resistant surfaces for safe use
- High mechanical durability during daily use
- Color-coded design for better orientation and traffic guidance
Ramps, Spindles, and Access Roads
Ramps and access roads are among the most heavily used areas of a parking garage. Acceleration, braking, and steering forces constantly act on the surface here. Triflex systems can withstand high mechanical loads, and their rapid curing allows for particularly short closure periods during new construction and renovation projects.
Key Features:
- High mechanical strength under braking and steering forces
- Slip-resistant surfaces for safe vehicle handling
- Short closure times due to rapid curing
- Seamless waterproofing of joints and transitions
Mechanical Processing for Large Parking Deck Areas
Triflex SAM technology allows waterproofing and coating systems to be applied particularly efficiently and evenly. Machine application enables large areas to be coated quickly and ensures a consistently high quality of workmanship—ideal for parking decks and underground parking garages with expansive traffic areas.
Advantages of machine application with SAM:
• Rapid coating of large areas
Ideal for parking decks and underground garages with extensive traffic areas.
• Uniform film thicknesses and consistent quality
Machine application ensures reproducible results.
• High application throughput on the job site
Large areas can be coated economically and efficiently.
• Optimal complement to manual detail work
Machine-applied surface treatment combined with precise handwork on joints and details.
FAQ – Waterproofing and Renovation of Parking Decks
Renovation becomes necessary when damage occurs that compromises the durability or traffic safety of the surface. Typical signs include cracks in the concrete, spalling, moisture penetration, wear on the surface coating, or visible corrosion damage to the reinforcement. If rehabilitation is carried out early, consequential damage and significantly higher repair costs can be avoided.
Not all areas of a parking deck are subject to the same level of stress. The following areas are subject to particularly high stress:
- Top decks, due to weather and temperature fluctuations
- Ramps and spindles due to high shear and braking forces
- Entrances and exits due to heavy mechanical stress
- Joints and connections due to structural movement
Specially tailored waterproofing and coating systems are often used for these areas.
The choice of system depends on several factors:
- Use of the area (top deck, intermediate deck, ramp)
- Existing damage to the concrete
- Crack movement in the structure
- Mechanical traffic loads
- Requirements regarding construction time and closure periods
Based on this, a system is selected that meets the required system class and durability.

In Germany, coating systems for parking decks are often classified according to OS system classes (surface protection systems) in accordance with the DAfStb guideline. Typical classes include:
- OS 8 for traffic-bearing surfaces subject to high mechanical stress
- OS 11a / OS 11b for crack-bridging systems on areas subject to vehicle traffic
- OS 10 for waterproofing systems under mastic asphalt
The selection of the appropriate system class depends on the structural element, its intended use, and the existing damage patterns.
The duration of a parking garage renovation depends on several factors, such as:
- Size of the area
- Condition of the substrate
- The chosen waterproofing system
- Weather conditions
Thanks to their fast curing times, modern PMMA systems often allow for a significantly shorter construction period than traditional systems, which can reduce the duration of closures.
Yes, in many cases, renovation can be carried out in sections. This involves working on individual areas one after another, while other areas can continue to be used. Fast-curing waterproofing and coating systems allow for short closure periods and help minimize disruption to parking garage operations.
Substrate preparation is a critical step for ensuring the long-term durability of the waterproofing. Contaminants, loose particles, and damaged concrete areas must be removed before the new system is applied. Typical methods include milling, shot blasting, or grinding. Only a sound and properly prepared substrate ensures reliable adhesion of the system.
Service life depends on several factors, including the quality of workmanship, traffic volume, and regular maintenance. High-quality waterproofing and coating systems can function reliably for many years when installed properly and provide long-term protection for the structure.
