Joint Fillers

Fill joints, the point at where building elements and construction materials are at their weakest. Particularly where components are comprised of different materials, they may expand and contract differently when exposed to elements like heat, cold, water etc. When joints fail, buildings and structures may begin to leak their contents or allow the weather to encroach.
