Can you use Big Stretch on driveways, sidewalks, to seal cracks or expansion joints at the foundation of a home?
In many cases, this application for Big Stretch would work – since it is largely away from foot traffic. However, in order for Big Stretch to have a decent chance at handling much expansion/contraction (which is often severe in these locations), it is critical to properly clean the surfaces and install backer rod before applying the sealant. If this joint will experience sustained submersion, then Big Stretch will likely fail. [NOTE: Most sealants will have a difficult time in this situation due to the typically large amounts of movement that occur.
