Precast Concrete Manufacturer backed by 18 plus years of local experience.

Proprecast Designs started eighteen years ago with little more than determination and a willingness to learn. We came into this trade with minimum experience, but we showed up every day and put in the work. Over time, collaborating with contractors, architects, and designers across the Bay Area taught us things no classroom ever could.

Those years of hands-on collaboration shaped everything we do today. Every project, every conversation with a designer or builder, added to what we know. Now, we carry that knowledge into every piece we produce, from precast columns and wall caps to custom statues and mantles. We say it plainly: if you can dream it, we can make it happen.

We manufacture precast concrete and fiberglass products right here in Pleasanton, CA, with care put into every detail before anything ships. That pride in our work is not a slogan. It is the standard we hold ourselves to on every single order. When a product leaves our hands, it has to be right.

Our catalog covers a wide range of architectural and decorative precast needs. We produce precast coping, columns, pillars, quoins, window sills and trims, stair treads, balustrade systems, lightweight precast designs, and fiberglass balustrade systems. Whether you need a single custom piece or a full run of matching elements, we have the production capability to deliver.

We serve homeowners, contractors, and designers throughout the Bay Area and Central Valley, including San Jose, San Francisco, Palo Alto, Fremont, Los Gatos, Belmont, Livermore, Pleasanton, Los Altos, Tracy, and Santa Cruz. If your project is in our region, we want to hear about it.

Call us today at (408) 849-9826 or email us at Concretedesigns23@yahoo.com. We are available Monday through Saturday, 8am to 6pm, and happy to talk through what your project needs.
