Tunneling

Tunneling

We offer a range of soil conditioning agents for Earth Pressure Balance (EPB) tunneling applications.

Alongside our foaming agents we supply foam stabilizers and a catalyst for foam cavity filling. Selecting the correct foam profile ensures the job of soil extraction can be completed in a safer and more efficient manner, especially when operating under extreme site conditions, we can work together to create tailor made foaming agent formulations.


Our range includes:

Formulated foaming agent

MILLIFOAM® T-900

Formulated anionic surfactant. Provides excellent foam expansion and foam stability (ready-to-use formulated foaming agent).

Foaming agent
