The Problem with Standing Water in Parking Lots

When it rains, you might end up with a lot of standing water in your parking lot, which creates a safety hazard for the people who use it. If you’re a driver, your tires might have trouble engaging the pavement and stopping your car. If you’re a pedestrian, you might discover the usual “pedestrian refuges,” like medians, are flooded. And that forces you into harm’s way. 

But the water isn’t just an issue for the people who use your parking lot. It’s also an issue for the parking lot itself. Water can weaken the constitution of your pavement and, over time, that can lead to cracking and breakage. Then, once your pavement is compromised, water can seep into those cracks and erode the foundation down below. That leads to potholes and expensive repairs over the long haul. 

Creating Parking Lot Drainage

You don’t have to live with standing water in your parking lot. You simply have to create a system of drainage that’s really, really effective. But creating that drainage has quite a few moving parts, including: 

1. Your Parking Lot Needs to Have a Slope.

You might think your parking lot should be completely level. But that actually creates a problem: it invites all of the standing water to stick around. So, the idea is to give your parking lot a bit of a slope, which encourages the water to leave. Here’s the key, though—you don’t want that slope to be so extreme that it interferes with the usability of your parking lot. You want that slope to be subtle. So, the rule-of-thumb is that your parking lot should have a 1-5% gradient.

2. Your Parking Lot Needs Curbs and Gutters.

As you’ve just read, the slope of your pavement ushers the water away from your parking lot. But where is all of that water headed? You want to route it all towards a drain, and the best way to achieve that is with a system of gutters (curb and gutter, valley gutter). You’re basically directing water to the place it needs to go…the storm drain system. 

3. Your Parking Lot Needs to Have a Drain.

Okay, so this is where the magic happens. You need to have a drain that allows the stormwater to exit your parking lot. And the main consideration is the capacity of that drain. How much rainfall do you get? Is the water being routed towards a single drain? Or will multiple drains be sharing the workload? These are all important factors, because if you overload your drain you create a “traffic jam,” and you end up with standing water all over again.

4. You Need to Keep Your Drains Clear.

Not everyone makes this a priority, but maybe they should. Because if your drains are obstructed, they can’t really do their job. Take a broom or a rake and be sure to clear away any leaves, trash, and other obstructions. While you’re at it, give the rest of your parking lot a once over, too. Even if the debris is far from your drain, the second the wind picks up or it starts to rain, that junk funnels right back to your drain and creates a clog. In extreme cases, it may be necessary to clean the drainage pipes with a high pressure water jet.

When your parking lot has standing water, it creates a hazard for people and for the parking-lot itself. So, be sure to give your parking lot a slope, a system of gutters, and a high-capacity drain…because those puddles create a lot of headaches.

Black Diamond: More Than Just Paving

At Black Diamond, when someone asks for our elevator pitch, we just say we’re the best paving and concrete company in California. But we’re not in an elevator right now. We’re on a blog. And that means we have a lot more room to elaborate. So, here’s a detailed look at everything we do: 

We Install Asphalt and Concrete

When we say we’re in the pavement biz, that isn’t the actual material we work with. The actual material is primarily asphalt or concrete. And before we get started, our customers need to decide which of those two materials they’d like us to use for their project. That can be a fairly complex decision. Do they want to go with asphalt because it’s less money up front? Do they want concrete because it lasts longer? And how does the local weather and the property’s traffic patterns play into this? We’re here to walk you through all of this and more. And then we go to work installing your new pavement. 

We Work with Specialty Materials

Above, we mentioned that we “primarily” work with asphalt and concrete—that was a careful choice of words, because we also work with a few lesser-known materials. One of those materials is a fairly new technology called “plastic road.” That’s when plastic is recycled, melted down into a binding agent, and used to make an eco-friendly form of asphalt. 

We “Love2Pave”

We are experts in pavement maintenance, and we specialize in commercial, retail, industrial, multi-family residential properties (HOAs and apartment communities), and health care facilities. So, if you run a nonprofit, a commercial space, or a residential community, let’s pave. 

We Do Preventive Maintenance

Preventive maintenance generally refers to both crack sealing and sealcoating. Sealing cracks doesn’t make them disappear (you’ll still see them) but it does prevent water from eroding the base and weakening your pavement. Sealcoating is when we add a thin, protective layer to the top of your pavement to protect it from the elements. The goal with crack sealing and sealcoating is to get in front of problems before they get out of control. We can help with that. 

We Do ADA Upgrades

The Americans with Disabilities Act was passed in 1990 and was an important step towards creating equal access to buildings for everyone. If you’re a business, it’s really important that you comply with those regulations—not only to create a welcoming space for people of all abilities, but also to avoid some pretty hefty penalties. Do you have ramps in the right places? Are your walkways wide enough? How many handicapped parking spaces do you have? We know all the ins and outs of the confusing world of ADA compliance, and we’re here to help get you up to code.

We Educate

Asphalt and concrete jobs can last for decades, which means you’ll be living with your decision for an awfully long time. It’s best to get it right the first time…and we’re happy to walk you through the whole process. We host free “Lunch and Learn” seminars where we teach you about a wide range of paving topics. We do personalized consultations that are tailored to your needs. And we post reference materials on our website. So, whether you have a few questions about the job itself, or you need to do some financial forecasting, we’re always ready to engage. 

Our web address may say “Black Diamond Paving,” but we do so much more. We do all of the preventive maintenance. We help with financial forecasting. And we go out of our way to share everything we’ve learned in our decades of experience. So, if you’re interested in talking further, schedule a lunch and learn seminar today.

Seasonal Effects on Asphalt

The seasons are changing, and so is your asphalt. What do those changes look like? That’s a great question. And this article has all the answers.                   

The Hot and Cold Seasons

Your Asphalt Might Expand and Crack

Extreme temperatures tend to wreak havoc on pavement. Consider the following two scenarios:

  • Scenario #1 – You live in a warm-weather climate, like San Diego or Los Angeles. Those summer months can be tough on your asphalt. That’s because extreme heat causes your pavement to expand and, eventually, crack. 
  • Scenario #2 – You live in a cold-weather climate, like Lake Tahoe, Mammoth Lakes, or Big Bear. Those harsh winters can be equally tough on your asphalt. That’s because water can seep into the asphalt and freeze. And when that water freezes, it expands and, similarly, causes your asphalt to crack.

But there’s no need to worry; these changes usually happen slowly over time. Asphalt is a flexible pavement surface, so as long as you’re keeping up with regular maintenance, you’ll get the most out of your pavement investment. 

You Might See Waves and Soft Spots

Not only can the heat create cracks in your asphalt, it can also lead to depressions and soft spots. That’s because your asphalt is getting hammered with something called “solar radiation,” a force that causes your asphalt to change shape and weaken. These soft spots are most likely to come about during the summer season when the heat is strong and the days are long.

Your Striping Can Start to Fade

Whether you have a parking lot or roadway on your property, your asphalt probably has a bit of striping. Maybe it communicates that an aisle is “one way,” or maybe it defines the boundaries of each parking spot. You rely on that striping to communicate important information to drivers. During the summer months, the UV rays from the sun are stronger (and the sun beats on your pavement for more hours during the day) and can cause that striping to fade. If you see this happening, you can usually just touch up paint. But if the fading is extreme, it creates a potentially dangerous situation, and you’ll want to have the striping redone.         

The Rainy and Dry Seasons

You Might See Some Potholes

Rains can really take a toll on your asphalt. Let’s say a couple of cracks formed in your asphalt over the summer. Those cracks allow water to seep into the ground, and that seepage can wash away your asphalt’s foundation, weaken the surface, and create the perfect conditions for potholes to form. 

Your Asphalt Might Get Slippery

While slippery pavement is typically associated with snow and ice during the winter, warm, dry conditions can create slippery pavement, too. Without heavy rain to give your pavement a periodic wash, dirt and oil can build up—especially on a surface that’s not properly maintained. So when you get a drizzle of rain, that little bit of moisture combines with the oil and debris to create a grimey film that can actually be pretty slick. And this can be even more dangerous because motorists aren’t expecting slippery conditions.

Black Diamond Can Help with Seasonal Wear and Tear

Asphalt, just like anything else, will naturally degrade over time. But here’s the good news: There’s something that you can do to significantly slow down that process. You can hire Black Diamond. We’ll come out to seal the cracks, do the preventive maintenance and all of the sealcoating. Call Black Diamond today to protect your asphalt against the seasonal extremes. 

Crack Sealing 101

Everyone knows it’s bad when your pavement cracks. But very few people understand why. Here are three main reasons:

  1. Cracking leads to more cracking; if it goes untreated, the problem escalates.
  2. Water makes its way through those cracks, which can lead to potholes. These are objectively worse than cracks.
  3. Cracks are just so dang ugly.

So, here’s how to seal the cracking in your pavement, protect your surface, and preserve your curb appeal.

You Can Only Seal “The Right Type of Crack”

This is a bit of an oversimplification. But speaking broadly, we seal the cracks that look like a straight or crooked line. If you’re interested in the technical terms, those are usually called transverse cracks and longitudinal cracks. But cracking that looks more like a spider web—called “alligator cracking”—isn’t right for sealing. Neither is cracking that looks like an elaborate sequence of alien crop circles.

Try to Catch the Cracking Early

Cracking is like any other problem; it gets worse over time. For example, when the temperature fluctuates, your pavement expands and contracts. That’s normal. But when you have cracking in your pavement, that expansion and contraction will make the cracking even worse. Once the crack is wider than 1.5 inches, it’s not right for sealing and has to go through a different, more complicated (more expensive) process. So, you always want to jump on these things early. (Or call Black Diamond and we’ll jump on it for you.)

Cleaning the Crack

The first step we do is to make sure the crack is completely free of debris. That cleanliness creates an ideal surface for the sealant to stick to.

The Hot Air Lance

As we’ve mentioned above, the sealant has trouble bonding to wet surfaces. But it’s not just water we need to worry about. Asphalt has a natural presence of oils, and we have to blast the crack with a hot-air lance that burns those oils away. These things can get up to 2,000 or 3,000 degrees, so it’s important this is done by a true professional. There’s a delicate balance between burning away the oils and using so much heat you damage the remaining pavement.

Selecting the Right Sealant

We’re almost ready to seal the crack, but there are different types of sealants we could use. Some are more flexible. Others are more rigid. When we take a look at your pavement, we assess many factors, such as the climate in your location, the amount of traffic your pavement gets, and the overall scope of the project. Like most things, crack sealing isn’t a one-size-fits-all job.

Sealing the Crack

Now it’s time to seal the crack. And for that, we need to bring out our trusty “pour pot.” As the name suggests, this helps us pour the sealant over the crack. Then we even it out with an asphalt squeegee. And after the sealant cures, traffic can get back on the surface. Keep in mind that you will still see the cracks but they will be sealed.

For all you #satisfying fans, we have a video where you can see our crack sealing process in action. Or give us a call to watch us fix up your pavement in real life—which is more than #satisfying. It’s just good sense.
