This product was designed to improve the productivity of ground support installation in underground mining and tunnelling applications. Using the pumpable resin enables the load to be taken up in minutes rather than the typical 24 hours from cementitious grouted systems. Typical applications of CarboThix™ include grouting of cable bolts, solid steel or GFRP bolts, self-drilling anchors and one-step bolting operations in automated mode or for consolidation injection works in direct overburden.
