"I've known CellFill℠ owner James Diver for 18 years and he has always been ingenuitive and at the forefront of lightweight concrete design and testing. I'd recommend him for any cellular concrete project no matter the size or complexity."

"I work closely with the CellFill℠ team as a product representative, marketing the company and the product to engineers, counties, municipalities and owners in the state of Oklahoma. Every time I mention CellFill℠ to my clients, their interest is immediately piqued. Almost every designer or specifier has an immediate use and application for cellular concrete, and when I talk about the company and the owner’s passion for the product, the specifiers are immediately sold. Marketing CellFill℠ and working with the company has been one of the best business decisions I’ve ever made!"

"We were happy to demo the use of this product under our bridge abutments. It is a problem we encounter in the maintenance of our bridges. James's crew was quick to identify problems with the process, correct them, and finish the project with great results. We look forward to using it in this manner in the future."
