Once these cracks have formed, the UV rays of the sun cause more damage by expanding the crack. Water can then seep in and settle in the base, causing more erosion. Since crack sealing can help prevent this from happening, it is a highly recommended cost-effective, preventative pavement maintenance procedure.
The best time of year to perform crack sealing is in the spring or fall when there is less expanding and contracting of the asphalt with extreme temperature changes like in the summer and winter months. Treating cracks at this time of year enables the sealant to fill and seal cracks more effectively since their size is more consistent.
Crack filling work is guaranteed by a one and a half year warranty.
