Basalite, acquired by Pacific Coast Building Products in 1979, has become one of the largest suppliers of concrete masonry products in the Western United States. Product lines include structural block, interlocking paving stones, wall systems, retaining walls, ornamental and garden products, and a full range of sack goods. The use of Basalite Concrete Masonry Units, or CMU, has grown rapidly in demand over the past couple of decades. This has been due to not only the building boom in northern California, but also as result of advances in building design and changes in architectural preference. Basalite Concrete Products manufactures hundreds of types and styles of concrete structural block. The company presents a complete offering of custom colors, shapes and sizes in most product lines and often works with architects to create effects that showcase the building's design.
