Sealants and Backing Rods: Types and Uses

In many types of construction work, you’ll find cases where there are gaps and cracks that need to be sealed. And not only for aesthetic purposes but also sustaining structural integrity, like gaps between concrete walls that may expand or contract under different temperatures. Similarly, in cracks and gaps in window panes where the cheap sealant has degraded over time resulting in unwanted drafts or water leakage. To avoid the protrusion of gasses and liquids, two surfaces of the same or different materials can be sealed to make a water and airtight joint.
