Over 50 Years of Innovation

Cell-Crete, a pioneer of the light-weight insulating concrete industry,
dates back to 1956 when its founder, Louis C.G. Fisher developed a
light-weight concrete flooring systems for apartment buildings. Called
Elastizell, this new flooring technology filled the need in wood-frame
apartments for providing sound insulation in the raised floor-ceiling
assembly replacing the ineffectual “sound board”. Within five years the
Elastizell Floor system became the nation’s standard method for
providing sound attenuated wood frame multi-story buildings.

“Our biggest challenge during these early years was to develop small
line concrete pumps that would work for this type of installation,” says
Fisher. There were no portable concrete pumps available. “After a great
deal of experimentation with the West Coast emerging concrete pump
industry (Azar, Mayco, Thompson), suitable pump equipment was created.

Cell-Crete Corporation was incorporated in Rosemead, California in 1965. Three years later, Fisher’s ingenuity led to yet a second major innovation, which is responsible for over 60% of the firm’s business today – the Concrete Insulating Roof-Deck System (EICRS). This system combines insulating concrete with expanded polystyrene board (EPS) to provide a firm, properly sloped underlayment for waterproofing membrane and the state mandated energy conservation requirements.
In the past 20 years, gypsum-based floors, such as Maxxon Flooring Underlayments, have replaced the light-weight concrete floors. Geotechnical in 1973 Cell-Crete applied the Elastizell Engineered Fill (E.F.) for Geotechnical applications – i.e., annulous fills in pipeline construction rehabilitation, pipeline abandonment, bridge approaches, load reducing fills, highway stabilization. These applications are especially suited for solving construction problems of unstable soils at marginal building sites as at estuaries, tidelands, flood plains and peat boggs.
