Community Involvement

United Rock is deeply rooted and extremely active within our communities. United Rock also believes that improving education strengthens our neighborhoods, which is why we work closely with various schools and universities through promoting education, volunteering, and giving.

United Rock is also actively involved with the Irwindale Education Foundation and the Irwindale Police Officers Association.


Primarily consisting of crushed rock, sand and gravel, United Rock Products manufactures most products that specifically cater to the construction, ready mix, and asphalt industries. However, we are able to manufacture specialty products based on the client’s request.
