Materials We Furnish

DeSilva Gates Construction has always maintained a firm belief that in order for us to deliver quality infrastructure projects to our clients in the most timely manner possible we needed to have control of our primary construction materials. Over the last 40 years we have produced more than 50 million tons of construction aggregates and 20 million tons of asphalt products at our various facilities throughout the San Francisco Bay area and Northern California. Furthermore, we have over one billion tons of aggregate reserves permitted at our two quarry facilities in the Sunol area that will allow us to service the Greater Bay Area for at least another 40 years into the future. Our ability to manufacture and transport quality construction materials at high production rates sets us apart from our competition and gives us the ability to deliver even the largest infrastructure projects faster than our competitors.

Green Products

DeSilva Gates Aggregates promotes the use of reclaimed asphalt pavement (RAP) and warm-mix asphalt (WMA) technologies, these two production methods conserve raw materials and energy, cut emissions from operations and improve environmental conditions for workers. Using RAP is more cost-efficient, and is often equal or greater in quality than traditional methods.
