Rural builders and ready mixed concrete producers have shared the sagging farm economy with farmers and other agri-businesses. Now there are encouraging signs for improvement. The potential exists for some increase in remodeling and construction of facilities. PAVING The most common farm application for concrete is a slab on ground for feeding floors, feedlots, and floors in livestock buildings. Livestock building floors and outside paved areas on which loads are limited to livestock, cars, small trucks, and smaller farm equipment need only be four inches thick. Areas subjected to heavier equipment, such as large trucks, grain wagons, and manure tanks may need to be as much as eight inches thick. MANURE STORAGE Concrete structures for manure handling and storage have been a major use of concrete on farms for more than a decade. Although the demand has been severely curtailed in the past few years, there is renewed interest in making improvements to existing manure handling facilities. Most of this activity will involve adding on or remodeling. Facilities will be built or remodeled with gravity-drain gutters, flush gutters, or scraper systems. Concrete manure storage tanks are cast in place or built with precast sections and may have any desired shape. CONCRETE WALLS Concrete walls should be considered for all farm building applications because concrete is the only material with all the desired properties: durability, strength, fire resistance and economy. If used properly, concrete can help control rodents, protect the wall insulation from damage by rodents, protect livestock and machinery, provide easy-to-clean surfaces and serve as the heat storage medium for solar heating systems.
