“For over the past thirty years I have delivered rock from Dutra to Contractors and Homeowners. The rock product that is mined at Dutra’s San Rafael location is of the highest core density. Therefore, whether it’s rip rap for structural support or base rock for compaction, the customers are very happy with the product.
I’m very grateful to the employees of Dutra for their accommodation and courteous help and support."
