Diamond’s durable precast concrete products are cast in re-usable molds, do not decompose or emit any toxic fumes, gases or harmful components and require little need for repair or maintenance over their long lifetime, making them ideal for both hot and cold climates. In addition, we strive to maintain this lower environmental impact by using only local resources for all of our concrete production, thus further reducing our climate footprint for an overall green alternative!

We Use Spray-Lock Concrete Protection

A sustainable concrete building process includes energy reduction, material use stewardship, and the need for less expense and upkeep efforts. That’s why all Diamond products are manufactured using Spray-Lock’s Amorfa concrete additive. Amorfa reduces permeability while enhancing the overall characteristics of our mix design and results in greater UHPC-level durability, attack resistance, less maintenance, efflorescence protection, better appearance and a longer product lifecycle for a more sustainable and worry-free precast concrete product solution.

Exceptional Customer Support

Known for our long history of workmanship, attention to detail and pride in our products, the Diamond Design Precast team is here to provide you with superior customer service and support for all your project needs. From the time you order to when you receive your final product ready for install, we are with you every step of the way!
