Crack & Joint sealing is an integral part of any pavement maintenance programme to prevent the deterioration of a cracked pavement by water ingression. An effective crack seal will extend the life of a cracked pavement until it is resurfaced.
While crack sealing is used to repair cracks, there are additional techniques that can be used in combination to increase its effectiveness. One of these is crack routing. With crack routing, a machine is used to open up the cracks, widening and deepening them. After this is done, the hot sealant is poured in, filling up the crack. When done together, crack routing and sealing can drastically extend the life of your pavement.
