This Section is based on the products of Basalite Concrete Products LLC, which is located at: 605 Industrial Way Dixon, CA 95620-9779 Tel: 707-678-1901 Fax: 707-678-6268 Web Site: Click Here E-mail: Click Here to send an e-mail to Basalite Concrete Products LLC. [ Click Here ] for additional information. 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. Basalite has Concrete Products manufacturing facilities in six Western United States including, California, Colorado, Idaho, Nevada, Oregon and Washington. In addition, there are three manufacturing locations in British Columbia, Canada. Basalite 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. The full line and custom options are available to builders and developers. The Basalite Masonry Designer is an interactive tool, designed for architects, builders and contractors interested in exploring Basalite's wide range of block products, styles and colors. This tool allows you to freely mix hundreds of materials and dozens of mortar colors. Interlocking Paving Stones: Basalite also manufactures a full line of interlocking paving stones. The appeal of interlocking paving stones has many homeowners, developers, and municipalities turning to pavers for their durability and appeal. To meet the demand, in 1997, the company opened one of the country's largest and most advanced manufacturing facilities in Tracy, California. The plant's sophisticated paver and block machine insures the truest measurements and color consistency.
