For over 50 years now the name Valley Slurry Seal Company has been synonymous with high-quality asphalt emulsion applications. In 1978, VSS established its first emulsion plant in Redding under the name of "Morgan Emultech" and began to build it into the premier West Cost emulsion Company. Now with three plants in California, VSS Emultech® combines the best in asphalt emulsion and application technology.

In 2000, for the new century, VSS changed the name of the premier emulsion company from Morgan Emultech® to VSS Emultech®. Different name, same great service, and leading technology.
