Sinnott Blacktop, Inc. is your one stop pavement maintenance professional. Serving the Northland since 1988, we offer year-round pavement maintenance services. As a business owner or manager, your asphalt pavement typically is not a major concern. Once major cracks, pot holes, or heaving occurs, then you may start to think there is need for some attention. An asphalt parking lot can begin to deteriorate within just a few years of installation without proper maintenance. To achieve a full-life expectancy from your pavement, annual maintenance shouldn't be an after thought but a priority. Studies show that by annually maintaining an asphalt surface, you can expect a 15 to 20 year life expectancy. By using our 2 to 6 year maintenance programs, we can help you get the most from your investment. Using factors, such as current asphalt condition, traffic patterns and work environment our estimators can help you design a comprehensive maintenance program specifically designed for your property.
