Cracks are an inevitable part of asphalt pavements. If left untreated they will continue to expand and eventually turn into a pothole. Cracks also allow water to infiltrate into rock bases, which can cause more pavement damage. We offer two popular methods of filling and maintaining cracks. There are generally two accepted methods for filling cracks. This first method involves using inexpensive cold, liquid crack filler. Using this type of crack filler is usually reserved for residential surfaces. The second method involves pre-treating the crack and applying a hot rubberized product to effectively control further damage.
Creve Coeur Paving typically only uses liquid crack filler on driveways. We do this because the cracks on a driveway are not subjected to the same type of traffic that parking lot or road is. Because of this, it isn't necessary to apply heavy duty filler. Also the liquid filler is more aesthetically pleasing. Liquid crack filler is left perfectly flush and when sealed, does not leave a veined look. Cracks will reappear typically within two years, but can be filled again for very little money.
If a more durable product is desired and aesthetics aren’t an issue, you can use our (commercial method of filling cracks on your driveway.
Commercial asphalt surfaces such as roads, or parking lots require a commercial method of crack filling. Creve Coeur Paving doesn't just fill the cracks in your surface. We pre-treat the cracks first with a highly pressurized crack jet. The crack jet also injects a stream of intense heat to dry the crack and soften the asphalt for a superior bond. In addition to these benefits, the crack jet will remove debris, litter, old crack filler, and vegetation from the cracks. You must have a clean, dry crack before you can fill it properly.
Once the crack has been treated by the crack jet, we will then apply Crafco PLS rubberized sealant to the crack. We will do this at a temperature range of 220 to 350 degrees. Once filled, a leveling tool strikes the surface to make the material level and flush. This method creates a band of filler that covers the crack and keeps it dry.
Keeping cracks dry is very important. Water is a main contributor to damage on parking lots. If cracks are not filled properly, water will be allowed to penetrate the surface of the asphalt which will eventually lead to severe damage. Once potholes form, the area will have to be excavated and replaced. This is a costly process that can be avoided by maintaining your pavement properly.
