The crack sealer Heats up pre formed blocks of the bitumen material to extremely high temperatures which melts into a liquid form. This liquid is then applied by an electronically controlled hand lance onto the cracks. Once applied the material then cools and turns back into a solid form, sealing the crack from any further damage from water etc… We have used this machine for jobs such as sealing between new bridge deck beams in preparation for the asphalt layers and repairing air port runways in preparation for asphalt overlay. Machine is supplied with expert operators trained in the use of a crack sealing machine. A very strict maintenance regime is up held with all servicing kept in house and monitored closely by Allpave management.
