The primary purpose of precast concrete wall panels is to weatherproof the building. Fortunately, precast concrete is weatherproof. The problem is weatherproofing the building at the joints between panels, and between panels and other elements. Since building frames move and concrete panels themselves expand and contract due to thermal and moisture changes, the joints must be sealed with a flexible medium. It is not within the scope of this paper to discuss building movements or their causes but how to design weatherproof joints between the elements of the building where differential movement takes place.
