A parking deck can be the first and last impression visitors have with your property. A clean, safe and attractive structure can say so much about you, while a rundown and unkept structure can show indifference. The most important part of a quality parking deck is the foundation. The flooring in your parking deck is the biggest factor to safety, longevity and the overall appeal of your facility.

Selecting the proper flooring material for a parking deck is not just a decision based on appearance alone. It’s a decision that requires you to evaluate your individual needs, environment and long-term objectives. This comprehensive guide is designed to walk you through the critical factors to consider, the most popular materials and the best practices for making an informed choice to protect your investment for years to come.

Why the Right Flooring is so Important

Parking garage flooring sees one of the harshest daily environments of any floor in existence. Between the everyday weight of cars, and the heavy foot traffic in an industrial building like this, not to mention exposure to the elements and all kinds of chemical spills, the surface needs to be strong. A good flooring system is important for a few very good reasons.

Durability and Longevity

Above all, parking deck flooring is meant to protect the concrete slab on which it is installed. Water, de-icing salts and automotive fluids all attack unprotected concrete, corroding the steel reinforcement, causing cracks and creating structural decay. A quality flooring system provides a seamless, waterproof barrier that keeps those destructive forces from causing expensive and hazardous structural damage, lengthening the life of the entire structure and keeping you from having to pay for major structural repairs.

Safety of Drivers and Pedestrians

Safety should be a major concern in your parking deck. Wet or oily spots can be dangerously slippery for cars and pedestrians alike. The safest flooring options feature slip-resistant textures that provide additional traction, even when wet. Bright, reflective coatings can also help improve visibility, making it easier for drivers to maneuver and see pedestrians. Clear markings for driving lanes, parking spaces, and pedestrian walkways are also important for keeping traffic flowing smoothly and safely.

Appearance and Property Value

In addition to being safe, your parking deck should also be a pleasant place for drivers and visitors. A dirty, dingy, and poorly maintained parking deck reflects badly on your property. Cracks, stains, and faded lane markings create an impression that the rest of the building may be similarly substandard. Luckily, today’s flooring systems are available in a wide range of colors and finishes. By choosing an attractive and professional-looking surface, you can also boost your curb appeal and property value.

The Most Popular Deck Flooring Systems

There are a variety of different flooring systems that can be used for parking decks. Each comes with its own set of advantages and disadvantages. The three most popular choices are epoxy coatings, polyurethane membrane systems, and sealed concrete.

1. Epoxy Coatings

Epoxy coatings are a two-part system consisting of a resin and a hardener. When mixed, they create a chemical reaction that results in a rigid, durable, and high-gloss finish. Epoxy is a popular choice for its protective qualities and aesthetic versatility.

Pros:

• High Durability: Creates a hard, abrasion-resistant surface that stands up well to heavy traffic.
• Chemical Resistance: Excellent at resisting damage from oil, gasoline, and other common automotive chemicals.
• Aesthetic Appeal: Available in a wide range of colors and can be finished with a high gloss, improving brightness and visibility.
• Easy to Clean: The seamless, non-porous surface makes cleaning up spills simple.

Cons:

• Brittle: Tends to be rigid and can crack if the concrete slab underneath moves or cracks.
• Susceptible to UV Damage: Standard epoxy may yellow or degrade over time when exposed to sunlight, making it a poor choice for top layers or decks that are exposed to direct sunlight unless a UV-stable topcoat is used.
• Slippery When Wet: Unless aggregates or anti-slip additives are added, it can be very slippery when wet, requiring careful consideration of traction.

2. Polyurethane Traffic Membranes

Polyurethane (PU) traffic coating systems are multi-layered solutions designed specifically for parking structures. They typically consist of a primer, a waterproof polyurethane membrane, and a durable, wear-resistant topcoat.

Pros:

• Flexibility and Crack-Bridging: PU is more flexible than epoxy and can stretch and move with the concrete. This “crack-bridging” ability makes it great at preventing water from reaching the concrete slab through hairline cracks.
• UV Stability: Polyurethane is naturally UV-stable and therefore well-suited for areas with direct sunlight.
• Superior Waterproofing: The flexible membrane offers exceptional protection against water intrusion, the leading cause of concrete deterioration.

Cons:

• Higher Cost: These systems are typically more expensive than epoxy systems due to the multi-layer application and material costs.
• Longer Curing Time: May have a longer curing period, resulting in more downtime for the parking area.
• Strong Odor During Application: The application process can emit strong odors, which may be a concern in occupied buildings.

3. Sealed and Polished Concrete

If you are looking for a more budget-conscious alternative, you can seal the concrete. Penetrating sealers are a high-quality sealer that will penetrate into the concrete slab and create a barrier to moisture and chemicals. Polishing the concrete will also harden and improve the surface appearance.

Pros:

• Inexpensive: This is the least expensive option and can work well for large areas.
• Natural Look: If you like the industrial appearance of concrete, this option will allow you to have it.
• Breathable: This method will allow moisture vapor to escape the slab, which can be helpful under the right conditions.

Cons:

• Limited Protection: It will not offer the same level of protection from heavy abrasion or chemicals that coatings do.
• Will Not Bridge Cracks: It will not stop water or other liquids from penetrating existing or future cracks in the slab.
• Susceptible to Staining: Oil and other fluids can still stain concrete even if sealed.

Parking Decks: Key Factors to Consider When Choosing

Selecting the appropriate system is based on an analysis of your specific needs. Below are some of the key considerations to make before you choose.

• Traffic Volume: High traffic area? In an area where you will have heavy foot traffic or machines, you’ll need a system that can hold up against the punishment such as a heavy-duty polyurethane membrane or a high solids epoxy.
• Exposure to the Elements: Covered or exposed deck? If your deck is in direct sunlight, you’ll need a UV stable system such as a polyurethane system. In climates where you will experience freeze/thaw cycles, you will want to choose a flexible and waterproof membrane, so water cannot seep into cracks and then freeze which can cause major damage.
• Maintenance Needs: How much time and effort can you put into maintenance? Epoxy and polyurethane coatings require very little maintenance (generally just regular cleaning). Sealed concrete typically requires more maintenance, as it may need to be resealed more often.
• Budget: While budget is always a consideration, you should also consider the total value. Choosing the lowest up-front cost system might mean you spend more money in the long run on repair and replacement. It is often best to invest in a system that will last longer and provide a greater return.

Installation and Long-Term Maintenance

The success of any floor system is entirely dependent on its installation. First and foremost, the surface preparation is key. The concrete must be clean, dry, and free of any contaminants. This usually requires some form of shot blasting or diamond grinding to provide a suitable profile for the coating to key into.

Maintenance Tips to Maximize Lifespan:

• Regular Cleaning: Keep the floor clean by removing dirt, salt, and other debris that can act as abrasives. It helps to set up a regular cleaning schedule for the floor.
• Prompt Spill Cleanup: Address any spills of oil, gasoline, or other chemicals promptly. Use a quality detergent to break down these substances and avoid staining the coating.
• Periodic Inspections: Conduct regular inspections of the floor to look for any signs of damage or delamination. Fixing minor issues can help avoid larger, more expensive problems in the future.
• Re-coating as Needed: The topcoat will eventually wear down and will need periodic replacement to restore the system’s protective qualities and aesthetic appeal.
