The roots of Heritage Concrete stretch back to 1934 when Alexander Petrillo produced the first yard of concrete as A. Petrillo and Sons in Wilmington, Delaware. Today, the daily operations at Heritage Concrete continue to be managed by the fourth generation of the Petrillo family. For over eight decades we have produced ready-mix concrete and have been a part of the local community on both a business and social level. We remain committed to helping customers in our core markets of Delaware, Pennsylvania and Maryland through donations, charity, sponsorships and community and trades involvement.

Heritage Concrete has four locations that manufacture and deliver ready-mix concrete throughout New Castle and Kent Counties in Delaware, Chester and Delaware Counties in Pennsylvania, Gloucester and Salem Counties in New Jersey, and Cecil and Kent Counties in Maryland. Our fleet consists of 65 front discharge mixers and four concrete boom pumps.
