Can I use rubber expansion joints in a concrete slab? Can I use rubber expansion joints in a concrete slab?
A rubber expansion joint can be used in a concrete slab because it is very versatile and weather resistant. The basic expansion joint that is currently being used will expand and contract according to weather (from, for instance, moisture and freezing), but the rubber expansion joint will not. Throughout the world, road crews, bridge builders, and concrete workers have begun to use the rubber versions because of the long life that they have and because the weather does not affect how well they work. The rubber expansion joint is currently the best choice to use.
