L&M Construction Chemicals, Inc. was founded in 1961 by Lawrence E. Schwietz in Omaha, Nebraska. Since its inception, L&M has realized the building industry's need to improve the long term durability and appearance of concrete. In answer to those needs L&M has developed and introduced a number of concrete surface hardeners, densifiers, and other concrete products that are all environmentally sensitive, waterborne, low odor products to replace VOC containing, solvent-based cures, sealers, and water repellents in concrete construction.
