These injection pipes are used to facilitate the injection of chemical mixtures or mortars into loose or inconsistent soil within tunnelling works. The effect is the consolidation of the soil surrounding the injection pipe area.

The pipe is inserted into a previously drilled hole in the ground. Valves are positioned along the length of the injection pipe as reaquired. Once in position, the injection head and packer is inserted into the injection pipe and located next to the most distant valve. The injection mixture is pumped through the valve and into the surrounding soil. This is repeated for consecutive valves.

Important note: The Bekaert-Maccaferri joint venture: In October 2014, we entered into a global sales and distribution JV with Bekaert. The resulting joint venture, BekaertMaccaferri Underground Solutions will serve underground construction markets on a worldwide basis, except in mainland China and Hong Kong, Argentina, Brazil, Paraguay, Peru, and Uruguay, where Bekaert and Maccaferri will continue to operate independently.
