Root foaming, also known as chemical root control, is a method used to manage tree root intrusion in sewer pipes. A specially formulated foam is injected into the sewer line using specialized equipment. The foam expands inside the pipe, coating the entire inner surface, including cracks and joints where roots typically enter. The active foam kills the roots within the pipe and a short distance outside it (typically a few inches to a foot), stopping further intrusion. The technique only affects the roots within or very near the pipe; it does not kill the entire tree or Docusign Envelope ID: 1A791935-55C3-4976-BEBF-1D6F49DE749D
