Joint sealing is a common process in most construction systems including construction joints, expansion joints, cracks in slabs and fascia, open joints or cavities and joints in a façade. Concrete expansion joints must be sealed with a flexible sealant or an expansion joint strip, to prevent water from penetrating the joint and deteriorating the sub-base. If utilized early enough, joint sealing can defer and even eliminate the need for more expensive maintenance.
Joint resealing preserves existing pavement and extends its useful life by placement of an approved sealant material in an existing joint or crack to minimize infiltration of surface water and incompressible material into the joint system. Sealants can also reduce dowel bar corrosion potential by reducing entrance of de-icing chemicals.
Joint resealing is frequently done subsequent to diamond grinding concrete pavement. The diamond grinding process removes the old seal and resealing the joints helps preserve the pavement by preventing water and incompressible material from getting into the cracks and causing more damage.
