About Us

Mountain Gate Quarry has been providing the Northern California area with high quality rock and earth products since 1988. We are the North State’s most reliable quarry and construction product location.

Our specialty is our unique pH-balanced limestone, whose environmental friendliness makes it a perfect choice for the enviro-conscious engineer or construction crew. This limestone comes from the foothills of the southern Cascade Mountains, in a large deposit near Shasta Lake. We carry our special pH-balanced limestone in many diameters, including aglime, 3/4" base, and many larger gauges. View our sieve reports here.

For residential applications, we also offer high-quality fill dirt from the Shasta Lake ecosystem. This dirt is balanced and is ideal for landscaping, home gardening, and independent contractor work.

Our scales are certified by Weights and Measures and we offer certified scale tickets for any application.
