Being one of the most versatile building materials, concrete is used in many forms of construction. Reinforced concrete was used to make building columns and decks in high rises in the 1960’s to replace steel girders and steel decking. Concrete is often used in residential driveways, house foundations, walls, as well as many other uses such as paving and curb & gutter applications. Filling pre-made molds with concrete are referred to as Precast concrete used to produce a variety of items such as drainage piping. Large warehouses with a large flat floor and wall sections use what is called Tilt-up concrete construction. Crews will pour a large, flat floor, then spray it with a non-stick film. Using a crane, the wall sections are formed on top of the floors and are “tilted up” into place.
