About Us

Dosch King Emulsions has been providing asphalt foundations, repairs and seal coating throughout New Jersey, Pennsylvania, Connecticut and beyond since 1926. Established in Whippany by New Jersey’s first asphalt salesman, James King, Dosch King Emulsions has continued to take on new forms and incredible growth through the years. We have proudly adapted to the growing demands of our clients by seamlessly embracing new technology and products, and will continue to. You can rely on us to handle the hardest roadways, the most modern commercial projects and the finest driveway designs.

Though we have adapted to accommodate modern and growing needs, Dosch King Emulsions has remained in the King family throughout its near-century-long time in business, now into a 4th generation. We started out with liquid tar and asphalt distribution, later broadening to include chip seal and eventually emulsion and polymer manufacturing. We have grown upon these services and so many more to provide everything you need for laying new roads, restoring damaged ones, installing custom-designed driveways and everything in between.
