Each year, many miles of cracks in asphalt pavements are left unsealed. This allows moisture to creep under the asphalt and pavement deterioration begins. When moisture enters a pavement crack, it slowly works its way down to erode the base. The pavement begins to sink and crumble, causing more cracks to form and creating pot holes. This process is accelerated by freeze/thaw cycles of midwest winters. Crack sealing is a routine maintenance procedure that includes cleaning out the wide cracks and opening others so they are wide enough to accept sealant. We use a hot rubberized crack sealant which remains flexible. The flexibility of our sealant allows cracks to remain sealed in spite of the expansion and contraction of pavement throughout the year.
