What you should know about seal coat
before hiring a paving contractor...
|
Condition If your surface is rough, oxidized (faded to grey) or suffering intermittent cracking it is likely that sealcoat is the correct application to improve and extend the life of your asphalt surface. Sealcoat should only be applied to asphalt surfaces that have maintained their integrity. It will not correct failures nor improve grade and drainage issues. If there are structural or design problems with your asphalt surface, we can correct these issues and follow with a sealcoat to protect the existing and new pavement as well as provide you with a uniform appearance.
Sealcoat provides a new driving/wear surface to protect the large investment you have made in your asphalt. In Multi-Residential and Retail we often find excessive “oil spots” in the parking stalls and while sealcoat does not cure this problem it will improve the appearance and provide limited protection. |
Correction Preparation of the existing asphalt surface is a very important process in seal coating your parking lot. Calvac Paving will spend the time necessary to clean and prepare your asphalt to assure a durable and attractive product. We will remove all vegetation, and apply herbicide if appropriate. We will use Power blowers, scrapers, wire brushes and brooms to thoroughly clean the existing asphalt. This preparation may also include Mobile Sweepers, water trucks or buggies and vacuum trucks. We will burn, scrape and carefully clean the oil spots and apply an oil spot sealer with sand. We will mask utility covers and other structures to protect against coverage. We will apply hot rubberized or cold pour emulsion crack filler as directed. The consistency of the asphalt sealer is also very important to the durability of your sealcoat project. The addition of water is necessary for the application and actually improves the bonding of sealcoat to the existing asphalt surface. Calvac Paving will never exceed the manufacturer’s recommendations for dilution. Our 35 years of experience has shown us that the addition of latex and sand to the asphalt sealer extends the life of the sealer, and we include these admixtures in over 90% of our sealcoat projects. The combination of organized phasing, timely notification, effective barricading and traffic control with superior craftsmanship and products will provide you with the best result with the least impact upon you and your tenants. |

Cause Age, UV exposure, traffic and water intrusion are the typical factors that cause your asphalt surface to require Sealcoat. Cracking is also an issue with asphalt surfaces and if you choose to Crack fill your property it is likely that the entire asphalt surface should be seal coated to retard the appearance of additional cracking. The choice of a Sealcoat is often made in High Profile and Retail Properties for aesthetic reasons, i.e., curb appeal. |
