About Asphalt Sealcoating
When you are considering sealcoating your home, you need to decide how much the service will cost and what benefits it will offer. Here are some of the advantages and disadvantages of using tar-based sealants, and the requirements for sealcoating. Continue reading to learn more! You can also learn about the different types of sealants and how they can benefit your home. But before you decide to get your home sealed, you should know what it takes to make your house look great afterward.
Costs of sealcoating
Cost of sealcoating differs according to the type and amount of surface it is applied to. Residential properties typically require a single coat of sealcoating to protect them from the elements. Commercial properties, on the other hand, may require more than one coat. Commercial properties include office buildings, shopping centers, corporate campuses, industrial parks, self-storage facilities, trucking facilities, and retirement communities. Homeowners associations, apartments, and hospitality properties can also benefit from sealcoating.
Sealcoating requires proper preparation and materials. Unlike painting, sealcoating involves a little bit of equipment. While you can hire a professional sealcoating company, the average homeowner cannot afford to hire a sealcoat professional. The cheapest tool is an industrial push broom. You can also use a power blower to remove debris, which can cost more than $1500. Once you've found a reliable sealcoating contractor, it's time to get to work!
When it comes to materials, the cost of sealcoat depends on the amount of surface area it covers. The larger the surface area, the more expensive the sealant and labor. The table below outlines the materials, equipment, and labor costs of sealcoating projects. Each category has its own breakdown. If you're unsure of the exact amount you'll spend, contact a sealcoat contractor in your area and ask them to provide an estimate.
In addition to saving on labor costs, DIY sealcoating is a fun way to spend quality time with family and friends. While DIY sealcoating is a great way to save money, it requires poor-quality tools, trial and error, and can even cause you to ruin clothes and skin. For these reasons, hiring a sealcoating company is still a smart idea. If you're considering starting a sealcoating business, consider the costs and profit potential to get started.
The average cost for sealcoating a parking lot is approximately 40 cents per square foot. But that cost can be considerably higher depending on the type of equipment and sealant you choose. Low-end sealants cost anywhere from six to nine cents per square foot and will cover up to 400 square feet. Top-grade sealants will cost as much as $25 per pail. There are many factors that determine the total cost for sealcoating a parking lot.
Benefits of sealcoating
Besides its aesthetic benefits, sealcoating also helps extend the life of pavements. Its non-porous surface makes cleaning easier, while its superior sun blocking properties prevent fading of colors. Moreover, the process of sealcoating is more cost-effective than overlaying the entire pavement. And the savings are significant since sealcoating requires minimal maintenance and reduces repair costs. Therefore, it is beneficial for business owners to invest in sealcoating services.
Besides providing an extra layer of protection, sealcoating can also prevent cracks. Water will seep into untreated asphalt, spreading cracks and weakening its integrity. However, sealcoating prevents such damages by creating a protective layer on top of the asphalt. As a result, the pavement looks newer and lasts longer. In addition to this, pavement problems will be less frequent and will only show up if the sealcoating process is not followed.
Another benefit of sealcoating is that it helps accelerate the melting of snow. When applied, sealcoating also protects against rain, frost, and water penetration. However, you should make sure that the temperature of the pavement and the surrounding air are above 55 degrees Fahrenheit. Before applying the seal coat, make sure that the surface is free from dust and debris. If you need to cover a large area with sealcoating, you can also use a sprayer.
Apart from being more cost-effective, sealcoating can improve the appearance of your parking lot. For example, if your parking lot is in good shape, your customers will feel safer when they park their vehicles. In addition to this, sealcoating prevents potholes and asphalt cracks, which make parking lots look slick and safe. And if your parking lot looks old and shabby, potential customers will be repelled by it.
Similarly, asphalt pavements are susceptible to cracks and oxidation. Moreover, the expansion of water as ice can weaken the surface of the asphalt. And in some cases, the asphalt will completely wash out, destroying the gravel base beneath it. However, sealcoating can significantly extend the lifespan of an asphalt surface. And if you're wondering whether asphalt pavements need to be sealed, here's what you need to know.
Disadvantages of tar-based sealants
Many cities are hesitant to use coal tar products in new pavement. This is largely because of the carcinogenic risk of the substance, which is readily absorbed through the skin. In addition to this, coal tar-based sealants are not as long-lasting as asphalt alternatives. Therefore, customers might simply give up on resealing their pavement. This, in turn, could lead to a higher rate of resealing.
The environmental problems caused by coal tar-based sealants have prompted bans in 10 states and the District of Columbia. While research on trends in PAHs indicates that the pollution from coal tar-based sealants is not the main cause of PAHs, it may reduce their concentrations in urban water bodies. For example, a study by the University of New Hampshire found elevated levels of these chemicals in areas adjacent to coal tar. Additionally, officials in Austin, Texas, found high levels of PAHs in their waterways, which were attributed to coal tar-based sealants.
Another disadvantage of tar-based sealants is the high cost. Coal tar is expensive and not durable enough for commercial applications. In addition, it has been linked to increased traffic wearout, a condition known as raveling. DOT inspectors usually notice this problem when they come to inspect your pavement. There are no approved alternatives to coal tar emulsions. But coal tar has several advantages.
In addition to the high cost, it also contributes to pollution in the air. Children living near sealed parking lots ingest up to fourteen times more PAHs than children who don't live near these parking lots. Also, the dust generated by sealcoat abrading can lead to higher levels of PAHs than the concentrations in the air around a car. And if you're a sealcoat applicator, your skin is exposed to a higher dose of this toxic substance than you would inhale.
A study from 2009 suggests that coal-tar-based sealcoat contributes to greater PAHs than any other source. According to this study, coal-tar-based sealcoat contributed to 58 percent of the PAHs in Lady Bird Lake, a reservoir on the Colorado River in Austin. Since then, other cities have followed Austin's lead. In addition to imposing a fine, violating companies may face jail time.
Requirements for sealcoating
The initial application of sealcoat is important, but proper mix design and application rates are also important. Using a proper mix design procedure and Materials Inspection is essential to the success of any seal coat application. Once the binder is applied to the roadbed, the cover aggregate shall be removed by a rotary power broom. Then, pneumatic tire rollers will embed the cover aggregate. The inflation pressure for the rollers must be at least 80 psi. In this process, the contractor must adhere to a uniform spread pattern.
A proper cure time for sealcoats depends on weather conditions. The sealcoat material needs direct sunlight for the majority of its drying time. A mostly cloudy surface prevents proper drying and can significantly reduce the quality of the finished coating. If the surface is not fully dry, the application may be delayed or abandoned. For best results, the surface must be dry and free of water and dust before the final application. Then, the coating should cure for at least eight hours before it is opened to traffic.
The correct mix of a sealer is necessary to achieve a satisfactory result. The manufacturer of the sealer should recommend any additives that will enhance the performance of the sealer. If they are not supplied by the same manufacturer, it is advisable to consult the producer and manufacturer before making changes to the mix. Additionally, it is necessary to strictly follow the instructions on application and drying time. If the application process is not properly performed, the sealer may not be effective and may cause premature wear.
A good surface is essential for the proper application of a seal coat or chip seal. For instance, a surface that is subject to heavy traffic must be level before applying the seal coat or chip seal. This will prevent bleeding or the asphalt being tracked or failing due to excessive traffic. When the surface is unstable, a leveling course can be used before applying the seal coat or chip seal. When the surface is stable, the marking process can follow.
About Schaumburg, IL
Landkreis Schaumburg was created on August 1, 1977 within the framework of the Kreisreform (district reform) of Lower Saxony by combining the former districts of Schaumburg-Lippe and Grafschaft Schaumburg. The town of Hessisch Oldendorf was reallocated to Landkreis Hameln-Pyrmont. The communities of Großenheidorn, Idensermoor-Niengraben and Steinhude had already been allocated to the community of Wunsdorf and thereby became part of Landkreis Hanover.
The Landkreis Schaumburg essentially duplicates the borders of Schaumburg at the time of the Middle Ages. Schaumburg was a medieval county, which was founded at the beginning of the 12th century. Shortly after, the Holy Roman Emperor appointed the counts of Schaumburg to become counts of Holstein as well.
During the Thirty Years' War the House of Schaumburg had no male heir, and the county was divided into Schaumburg (which became part of Hesse-Kassel) and the County of Schaumburg-Lippe (1640). As a member of the Confederation of the Rhine, Schaumburg-Lippe raised itself to a principality. In 1815, Schaumburg-Lippe joined the German Confederation, and in 1871 the German Empire. In 1918, it became a republic. The tiny Free State of Schaumburg-Lippe existed until 1946, when it became an administrative area within Lower Saxony. Schaumburg-Lippe had an area of 340 km², and a population of 51,000 (as of 1934).
Hessian Schaumburg was annexed to Prussia along with the rest of Hesse-Kassel in 1866. After World War II, Schaumburg and Schaumburg-Lippe became districts within the state of Lower Saxony, until they were merged again in 1977.
The district (Landkreis) of Schaumburg has its northern half located in the North German Plain and the southern half in the Weser Uplands (Weserbergland). The Weser Uplands consist of hilly ridges and include the Wesergebirge, Harrl, Süntel, Bückeberg and Deister. The Schaumburg Forest is a continuous strip of woods running in a direction of approximately 60 degrees along the northern border of the district. Just beyond the northern border of the district is Lake Steinhude a 29,1 km shallow lake that is the largest in Northern Germany. The river Weser flows westward along the south of the Wiehengebirge through a broad valley and the town of Rinteln. The landscape is bordered to the west by the River Weser which is in the neighbouring district of Minden-Lübbecke. It flows north through the Westphalian Gap towards the city of Bremen and the North Sea. In the flat North German Plain to the east of Schaumburg district lies Hanover, the capital city of Lower Saxony.
