Can I use metallic expansion joints in a concrete slab? Can I use metallic expansion joints in a concrete slab?
Metallic expansion joints can be used in a concrete slab because they will not freeze or contract due to water or moisture, as basic expansion joints will. Various metallic expansion joints are in use throughout the world in bridges, roads and parking lots. They offer a good expansion joint that is weather resistant, and they also allow various additions, such as speed bumps or spikes, to be made. Depending on the slab that is being poured and the application for which it is being used, a metallic expansion joint is a good alternative to a basic one that can be damaged by weather or through use.
