Does anyone know the proper name or the name of a product used between concrete joints? I had this epoxy rubber type material in the space between my two large concrete slabs for my driveway. It's since deteriorated down to almost nothing. I also often see this epoxy type material used in the joints throughout the city mainly in front of large office buildings. Thanks so much in advance
it should've been neither caulk NOR epoxy,,, most likely it probably was either polyurethane OR silicone - both are sealants & need to be installed correctly to result in acceptable service life,,, you can find info by looking at dow-corning's install directions which also notes the use of closed cell backer rod to prevent full adhesion as you only want joint sealant to adhere to the joint walls - good luck !
