What makes us so great
Our Story
Established in 2000 by good friends, Warren Holt and Bob Leppek, Central Valley Engineering & Asphalt has become a regional construction leader. As a State Board Licensed Professional Engineering Contractor, we hold the highest standard of competence and assurance of quality.
We specialize in asphalt paving, concrete construction, grading, and underground utilities. Our projects range from small driveways to large municipal roadway reconstruction projects. We have a broad range of customers including public, military, commercial, industrial and private construction with a proven track record of customer satisfaction.
We exist to build smooth, long-lasting surfaces that improve the curb appeal and value of your property while adding the durability and practicality your surfaces need. With our own equipment, we are committed to delivering high quality asphalt or concrete solutions at the best rates.
We believe in creating and maintaining long term partnerships with our customers, vendors and our community. We aim to earn and retain their trust year after year through excellent service from a team of talented hard-working individuals. Our company growth has brought life to hundreds of shopping centers, homes, city streets and more. Much of our work comes from the recommendation of our customers who spread their satisfaction to others. These relationships with customers support our pledge and dedication to our work.
