A parking structure is a massive investment, and unlike a standard surface lot, it faces a unique set of structural challenges. Here in Green Bay, WI, those challenges are amplified by our harsh climate. Between the heavy loads of parked vehicles and the relentless freeze-thaw weather cycle, your parking deck is under constant stress.
Ignoring maintenance on a parking structure isn’t just an aesthetic issue—it’s a safety hazard and a financial liability waiting to happen. Concrete spalling, water infiltration, and rusting reinforcement steel can compromise the integrity of the entire building if left unchecked.
At American Pavement Solutions, we know that a little proactive care goes a long way. Whether you manage a multi-level garage or a smaller concrete deck, this guide will help you keep your structure safe, functional, and visually appealing for years to come.
1. Water Management: The First Line of Defense
Water is the number one enemy of parking structures. When water sits on concrete, it eventually finds a way in. Once inside, it can rust the steel rebar (which expands and cracks the concrete) or freeze and expand, causing surface damage.
- Check Your Drainage: Ensure that water flows freely to drains and doesn’t pool in corners or driving lanes. Clogged drains are a recipe for disaster. Regular inspections should ensure catch basins are clear of debris.
- Waterproofing and Sealants: Concrete is naturally porous. Applying a high-quality breathable concrete sealer or traffic coating blocks water and deicing chemicals from penetrating the slab. This is essential for protecting the steel reinforcement within the deck.
2. Address Concrete Spalling Immediately
Have you noticed areas where the concrete surface has chipped, flaked, or broken away? That is called spalling, and it is a common sight in Green Bay parking decks due to our winters.+1
Spalling often begins small—perhaps as a pitted surface or a shallow crater—but it spreads quickly. It creates tripping hazards for pedestrians and allows even more water to reach the structural steel inside.
How we handle it:
- Surface Cleaning: We remove loose debris and deteriorated concrete.
- Edge Cutting & Prep: We saw-cut a clean perimeter around the damage and roughen the surface to ensure a strong bond.
- Patching: We use high-strength repair mortars specifically designed to withstand traffic and weather conditions.
Don’t wait for “chunks” to go missing before calling a professional. Timely repair is critical for long-term durability.
3. Joint and Crack Maintenance
Parking structures are built with expansion joints to allow the concrete to expand and contract without breaking. Over time, the sealant in these joints can dry out or fail.
- Seal the Cracks: Small cracks should be sealed as soon as they appear to prevent moisture from seeping deep into the slab.
- Maintain Expansion Joints: These joints are vital. If the joint filler is damaged or missing, water (and salt) will pour directly through to the levels below, causing damage to the cars parked underneath and the structure itself.
4. Routine Cleaning and Winter Prep
It might seem simple, but keeping your deck clean is one of the best ways to extend its life.
- Sweep and Power Wash: Dirt, gravel, and trash hold moisture against the concrete. Regular sweeping prevents this buildup. A thorough power wash (ideally twice a year) reveals hidden cracks and removes oil stains that can degrade the surface.+1
- Manage Deicing Chemicals: In Wisconsin, we need to melt ice, but harsh salts can chemically attack concrete.+1
- Tip: Limit the use of harsh rock salt. Opt for sand for traction or non-corrosive ice melts that are safer for concrete surfaces.
- Tip: Wash the deck in the spring to remove any salt residue that accumulated over the winter.
5. Security and Lighting Checks
Maintenance isn’t just about the floor; it’s about the entire user experience. A well-maintained structure is a safe one.
- Lighting: Regularly check that all fixtures are working. Poor lighting can hide tripping hazards and reduce security.
- Bollards and Barriers: Inspect protective bollards near ticket booths, elevators, or corners. These safeguards protect your infrastructure from accidental vehicle impacts.
