SpeedBlock is a revolutionary new large format, structural hollow concrete masonry unit that can reduce build times and labor costs by up to 80% compared to traditional build techniques: 1 SpeedBlock CMU = 72 traditional 8" x 8" x 16" CMU blocks. Using our proprietary wet cast manufacturing process, SpeedBlock is cast and precut in our facilities, eliminating cutting and waste at your build site. These structural walls can be 300% stronger than traditional CMU construction. By eliminating on-site casting and cutting, or hand building masonry blocks walls, labor hours can be reduced by up to 80%, and cleanup at the end of the project virtually eliminated. SpeedBlock is rapidly becoming a material of choice for contractors, developers and builders throughout California and Nevada.

By working closely with customers to understand their needs, the company grew to play a role in building thousands of concrete structures. In 1997, he developed a new hollow block wall (CMU) system that provided exceptional strength and ease of installation. Erik partnered with John MacMillan nearly 10 years ago, with their investing millions into R&D getting the product ready to bring to market. The product caught on rapidly in Nevada and California, where more than 800,000SF were used in the construction of retail buildings, casinos, commercial buildings, industrial warehouses, sound walls, school gymnasiums and churches. For more than 4 decades, leaders of SpeedBlock have worked closely with corporate site managers, owners, builders and contractors and been dedicated to building a company based on a firm understanding of what matters most to them. This customer-centric approach is at the heart of everything we do.
