Stadium parking structures present some of the most challenging waterproofing conditions in the industry. Multi-level garages adjacent to stadiums experience extreme vehicular traffic concentrated in short event windows, exposure to tire wear debris, de-icing chemicals, automotive fluids, and constant moisture from rain and snowmelt. Our specialized parking structure waterproofing systems are engineered to withstand these demanding conditions for 15 to 20 years between major maintenance cycles.
The Unique Challenges of Stadium Parking Structures
Stadium parking garages differ from typical commercial parking structures in several important ways. Traffic loads are highly concentrated — a 50,000-seat stadium may see 10,000 vehicles arrive and depart within a two-hour window. This concentrated loading creates dynamic stress on deck waterproofing systems that steady-state conditions do not replicate. Additionally, the urgency of game-day operations means maintenance access is severely restricted, making system durability even more critical.
Our Parking Structure Waterproofing Systems
Vehicular Traffic Membrane Systems
Our primary system for stadium parking decks is a vehicular-traffic-rated, reinforced membrane system. These systems typically consist of an epoxy or urethane primer, a reinforced polyurethane or polyurea membrane, and a broadcast aggregate wearing course that provides the slip resistance required for both pedestrian and vehicular use. Systems are designed to meet ASTM C957 and ASTM C836 standards for traffic-bearing waterproofing membranes.
Crystalline Waterproofing for Below-Grade Levels
Below-grade parking levels in stadium structures are subject to hydrostatic pressure from groundwater as well as surface drainage. For these applications, we frequently specify crystalline waterproofing treatments applied to the concrete substrate. Crystalline chemistry penetrates the concrete matrix and forms insoluble crystals within the capillary pores, providing a permanent, self-sealing waterproof barrier that becomes part of the structure itself.
Drainage Systems and Slope Correction
Effective waterproofing in parking structures requires proper drainage design. Ponding water is the enemy of every waterproofing system. We assess existing drainage patterns, identify low points and drain blockage issues, and install slope correction overlays and supplemental drainage systems as needed to ensure rapid water removal from all deck surfaces.
Installation During Off-Season Windows
We specialize in completing parking structure waterproofing projects within compressed off-season schedules. Our crews work extended hours and deploy multiple application teams simultaneously to maximize productivity within your available window. We have successfully completed multi-level parking structure waterproofing on NFL, NBA, and MLB venues within 6 to 10 week off-season programs.
Long-Term Maintenance Programs
All of our parking structure waterproofing installations include a recommended maintenance protocol that specifies inspection intervals, cleaning requirements, and minor repair procedures to maximize system longevity. We offer ongoing maintenance contracts that include annual inspections, minor crack and joint repairs, and surface renewal treatments to keep your system performing at its best between major restoration cycles.
