DEA Incorporated provides the means to safely install steel raise liners with the following benefits:

• DEA Incorporated owns and operates the specialty equipment required to install steel liners from the top down, eliminating the need to have any personnel working underneath the raise at any time.
• Raise liners can be installed on an angle. Most lining installations become very difficult when not at 90 degrees.
• Underground liners can be installed at any diameter up to 10 ft.
• Liners can be of any thickness.
• Ore pass liners up to 3/4' AR plate have been successfully installed on slope in underground raises.
• Although the above features are important, safety is our biggest advantage. Our system provides the means to SAFELY, quickly and economically install steel liners in underground raises with minimal risk exposure to our crews.
