The backer rod becomes an integral part of the joint into which it is installed and therefore is available in a range of diameters to accommodate joints from 3/16 inch to 1-5/8 inch. It limits the depth of the sealant, therefore preventing excessive use of sealants. Because the sealant will not bond to the "skin" of the rod, it can stretch and recover with joint movement, with minimal stress being put on the points of adhesion to the substrate.CRL Closed Cell Backer Rod will not absorb water or wick water to joint walls which could cause adhesive failure. It is compatible with cold-applied sealants and its round shape promotes the preferred "hour glass" shape for joint sealants. Being easily compressible, it withstands hot and cold temperature extremes from -45 to 160 F (-43 to 71 C). It can withstand dynamic joint movement without shifting from position or losing its "grip" on the joint walls. CRL Closed Cell Backer Rod is chemically inert, and resistant to oils, gasoline and solvents. It will not stain or "bleed" into sealant material. Backer rod is typically used in expansion/control joints where cold-applied sealants are used. These joints would normally be found in curtain walls, construction partitions, precast panels, parking decks, door and window frame perimeters, coping, floor and deck joints, horizontal traffic joints and building rehabilitation.Proper size selection of CRL Closed Cell Backer Rod is important as it controls the depth of the sealant bead. It must be oversized (25 percent) to

I am using this backer rod for the cracks in-between my driveway slabs, to keep weeds from growing and it's working! Highly recommend.

Needed a larger amount, and this fit the bill at less cost than 20' lengths seen at stores. Appears to be same quality.

Workes well for my driveway in spots. Felt wasteful doubling 3/4" backer rod.
