Gilsulate® is the oldest name in underground insulation and corrosion protection. Installing Gilsulate 500XR is a simple and quick process. However, there are several important steps to follow to ensure a successful installation. A successful direct-buried system starts with a good design and includes every step all the way to the individual who backfills over the last bag. We would like to assist you in any way possible. Please contact us to help you with your individual project or application.
