L&M Construction Chemicals, Inc. was founded in 1961 by Lawrence E. “Larry” Schwietz in Omaha, Nebraska. Larry had the courage, tenacity, strength, and, most importantly, the vision to see the company through its early years.The company, originally based in the Schwietz home, grew rapidly. In 1962, the first public L&M office was opened in the lower level of a multi-story tire warehouse/construction supply house in Omaha. Fifty years later, L&M has grown to fully utilize a number of packaging plants and warehouses, along with an international distribution system.
L&M has always realized the construction industry’s need for form release agents and to improve long term durability and appearance of concrete surface hardeners and densifiers. These unique product innovations include DEBOND form coating, DRESS & SEAL the first non-yellowing acrylic cure, sealer and dustproofer and CRYSTEX non-shrink grout. Other popular product innovations include SEAL HARD, QUARTZPLATE and EMERY aggregate hardeners and toppings, as well as salt resistant, water repellents such as AQUAPEL.
