In Winnipeg cracks will happen. The extreme temperature swings combined with a moderate amount of precipitation is harsh on our roads and parking lots. These cracks, if left unaddressed will rapidly increase the deterioration of your asphalt. Whiteout Asphalt will apply a hot rubberized sealant, this will help to prevent water from seeping into the cracks and causing havoc. Crack sealing is a quick and effective way to help prolong the life of older asphalt.
