Great Lakes TV Seal, Inc. provides service for casting and adjustment ring replacement as well as rehabilitation of existing structures. Old castings can be removed from asphalt streets by coring a 48” hole through the road. The asphalt plug and casting are then removed. After the casting is replaced and the road surface put in place, you are left with a blacktop patch with no corners that is symmetric with the cover and appears to be part of the road as opposed to a patch.

GLTVS can provide numerous methods to seal and protect adjusting rings.
