About Seal Coating
Asphalt Sealing, or seal coating, is simply laying a thin protective layer over asphalt-based pavement to give it a protective layer of protection against the elements: oil, water, and U.V. The positive effects of asphalt sealing have long been debated. Some claim that asphalt sealing increases the lifespan of the pavement, but again, there’s no evidence that backs up those claims. Asphalt sealing can damage the pavement by creating cracks. The excessive water and oil that can be soaked into the asphalt also weaken its structural integrity. And the chemical fumes emitted during asphalt sealing can also be harmful to humans.
With all of that in mind, it’s not surprising that many business owners, when they set out to perform asphalt sealing, opt to go the non-per square foot route. The costs are much lower, often no more than a few cents per square foot. And the benefits of lower cost and improved performance are well-known. After all, if you want to save money, you want to reduce your operation costs.
But that brings us to our next question: Are asphalt sealing pads a good solution for parking lots, blacktop driveways, or other paved surfaces? As with any typical maintenance procedure, regular maintenance is the best way to reduce the cost of asphalt sealing. Sealing at least annually will help keep dust, pollen, and other pollutants from making their way onto your paved surfaces. It will also help protect your driveway from water damage, as well as mold and algae growth, both of which cause a lot of problems to homeowners.
Now let’s look at how often you should reseal your asphalt surfaces, especially if you’re going to go the non-per square foot route. The key, again, is regular maintenance. And as it turns out, the best time to perform asphalt sealing and resealing are during the cold winter months. There’s even been some recent evidence suggesting that the best time for asphalt sealing and resealing is during the fall when temperatures are quite low.
Why is that? Fall is when most asphalt-based park finishes and protective coatings need to be applied. Asphalt-based park finishes are very weather-resistant, but that doesn’t mean that they’re impervious to the elements. The rainy spring weather can still cause problems, as can heavy snow, ice, and even dew. So, by applying the protective coatings only during the wet winter months, you’ll be doing your park and business no favors, and in the end, your asphalt sealing and resealing efforts will be wasted.
Here’s why: Asphalt seal coats are extremely dense. Think about asphalt sealing and resealing – it’s the same product, just in a different form. And that means that you have to apply a lot less of it to achieve the same degree of protection. That’s why a lot of asphalt maintenance and repair companies (which specialize in asphalt sealing and resealing) will advise you to apply a minimum of three or four gallons of asphalt-based protectant per square foot of paved area. In other words, if you have a parking lot of ten thousand square feet, you’d want to apply three gallons per every twenty-five feet of the paved area.
If you were to apply that kind of service to your asphalt driveway, you could expect to pay anywhere from three to five dollars per square foot. Now consider that the average cost of asphalt sealing and resealing is only about two or three dollars per square foot. Multiply those two by the number of feet of asphalt you’re going to need to cover (per your parking lot, for example), and you quickly come to understand how much asphalt sealing and resealing would cost you. Applying the service yourself would cost you at least a thousand dollars or more. Not very appealing, I’d say.
But, don’t give up just yet – there are other ways to protect your asphalt driveway seal coating and resealing investment, and they won’t cost you nearly as much, so don’t rule them out just yet. One of those ways is called flashings, which are like raised bumps along the edge of your driveway that will serve as an additional traction aid when you drive over it. The average cost of installing these would be about two hundred dollars, with the total installed cost running into the thousands. Another less expensive alternative is a thin film of asphalt seal coating that has a plastic protective layer between it and the ground, as opposed to flashing. It’s about as thick as standard asphalt, which would then have to be applied to your asphalt driveway seal coating and resurfacing project in much the same way.
About Chesterfield, Missouri
Chesterfield is a city in St. Louis County, Missouri, United States. It is a western suburb of St. Louis. As of the 2020 census, the population was 49,999, making it the state's fourteenth-largest city. The broader valley of Chesterfield was originally referred to as "Gumbo Flats", derived from its soil, which though very rich and silty, resembled gumbo when wet.
Present-day Chesterfield is known to have been a site of Native American inhabitation for thousands of years. A site in western Chesterfield containing artwork and carvings has been dated as 4,000 years old. A Mississippian site, dated to around the year 1000, containing the remains of what have been identified as a market and ceremonial center, is also located in modern Chesterfield.
The present-day city of Chesterfield is made up of several smaller historical communities, including:
On January 24, 1967, a violent F4 tornado ripped a 21-mile (34 km) path of destruction across St. Louis County. It was the fourth-worst tornado to hit the St. Louis metro area and the most recent F4 tornado to hit the city. The tornado developed near the Chesterfield Manor nursing home and then moved through River Bend Estates and across northeast St. Louis County.
The name "Chesterfield" was given by landowner Justus Post who arrived in Missouri in 1815 and began amassing an estate in the location of the present-day city. Post had grown up in Vermont, not far from the town of Chesterfield, New Hampshire, which sits on the border between New Hampshire and Vermont. Although Post eventually left Missouri and moved to Illinois, his chosen placename of "Chesterfield" stuck.
For many years, "Chesterfield" was an all-inclusive place-name for a vast, unincorporated sub-region of western St. Louis County (called "West County" by metro area residents) containing the unincorporated historical communities listed above, plus areas now incorporated as cities of their own (e.g., Ballwin). Police and fire protection in the community were fragmented and sporadic, the former provided by St. Louis County. As the population grew, Chesterfield Mall and other retail and commercial real estate developments sprang up; however, many residents were concerned about the lack of quality public services, and that the municipal sales tax benefited the county instead of the community.
An organization was formed calling itself the "Chesterfield Incorporation Study Committee." Headed by its president, John A. Nuetzel (himself a former president of the River Bend Association, a zoning watchdog group), the members "passed the hat" at neighborhood meetings, engaged legal help, drew up metes and bounds, and forced several failed public votes for incorporation. After a number of years, in 1988, The City of Chesterfield was finally established by its residents, and has thrived as perhaps West County's premier residential, business, retail, and transportation center.
On July 30, 1993, the levee that protected Gumbo Flats (now known as the Chesterfield Valley) from the Missouri River failed. This was the first time the levee had failed since 1935. The town was told to evacuate, and the whole area of Gumbo Flats was flooded by feet of water. Today, the area has become the Chesterfield Commons retail area.
Chesterfield is located approximately 25 miles (40 km) west of St. Louis. According to the United States Census Bureau, the city has a total area of 33.52 square miles (86.82 km), of which 31.78 square miles (82.31 km2) is land and 1.74 square miles (4.51 km) is water.
Portions of Chesterfield are located in the floodplain of the Missouri River, now known as Chesterfield Valley, formerly as Gumbo Flats. Here several small creeks empty into the Missouri River (Caulks Creek and Bonhomme Creek). This area was submerged during the Great Flood of 1993; higher levees built since then have led to extensive commercial development in the valley. Chesterfield Valley is the location of Spirit of St. Louis Airport, used for corporate aviation, as well as the longest outdoor strip mall in America.
