Poli_R + Iso_R
A two-part polyurethane mixture used for consolidation of soils within tunnelling works.
These are chemical products that are mixed before the grouting stage to create a lightweight and expansive closed cell foam. When it comes into contact with water it forms a foam that blocks any accidental inflow of water.
It is also widely used to fill the cavities that sometimes form or which are encountered during tunnel excavation work.
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.
