How to Crack Seal Right?

Sealants should be selected based on pavement condition, climate, pavement movement, service life needed and sealant properties.Cracks come in all shapes and sizes. Sealing them in a timely manner is one of the most effective ways to maintain the quality of your pavement.One of the biggest mistakes is waiting too long to begin maintenance.

By crack sealing your pavement when cracks first appear, you keep the water and non-compressible materials out of the cracks

These non-compressible objects will not compress as the crack contracts in warm weather.

Select Your Sealant

Sealants should be selected based on pavement condition, climate, pavement movement, service life needed and sealant propertie.Although project specs may consider the other factors, it’s important to pay attention to the type of sealant you use, with or without project specs to follow.For example, cooler climates require more flexible sealants than hotter climates.Using a softer material in a hot climate could cause tracking of the sealant by vehicle or pedestrian traffic,In hot climates, there is less movement of the pavement surface in general and, therefore, no need for a very flexible material. If you use a less flexible material in a cooler climate, where the pavement will be exposed to greater temperature swings and will have more thermal movement, then the sealant may crack prematurely. This defeats the purpose of why you’re repairing the cracks in the first place.

Prepare for the Job

Before starting the job, you’ll need to consider the weather you’ll be working with.

During spring and fall, cracks are in an average position—not completely open and not completely closed

Before heading to the job, you’ll also need to make sure all of your equipment is in working order, that shaping tools are clean,

and that you have the right wand tips for the job.
