TekGrout® is a single-component, variable strength cementitious injection grout designed as an alternative to polyurethane systems.
A wide flexibility with strengths and viscosities enables excellent strata penetration and gel times as low as 40 seconds. The material’s adhesive and interlocking characteristics collectively assure a solid bond.
These products were 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.
CarboThix™ Fast is an immediate partially stiffening and very fast curing dual component silicate resin for bonding injection drilling anchors, also for rock stabilization and water sealing. CarboThix Fast was developed to improve the productivity of ground support installation in underground mining and tunnelling applications. Using the pumpable resin enables loads to be taken up in minutes rather than the typical 24 hours from cementitious grouted systems. Typical applications of CarboThix Fast include grouting of cable bolts, steel or GFRP bolts, and sealing of roof bolts.
Typical applications of CarboThix™ 2 include sealing of injection bolts, steel or GFRP rods, and sealing of roof bolts. During application, the two components are intimately mixed and achieve a grease-like viscosity (the so called Thix effect) so that the grout stops flowing and cures to form a tough elastic and non-porous resin that will not mix with water or be diluted in wet holes.
Celroc P is a high-strength, non-shrink, non-metallic grout consisting of rapid hardening hydraulic cement and super plasticizer. Designed to produce a pumpable grout at low w/c ratios with the unique features of being highly resistant to dilution in moving water and aggressive ground conditions.
Other important uses include controlling water inflow into shafts and tunnels during excavations, pre-grouting of TBM/EPBM tunnel headings, formation of impervious grout curtains to contain pollution by hazardous waste and cut-off walls into alluvial deposits at dam sites.
The Terracol System is a completely water soluble process consisting of two components:
The amount of Terracol Part B - hardener needed ranges from ~10:1 to 5:1 by weight depending on the desired gel time (ie. a 6.6:1 ratio results in an approximate 30 minute gel time at 70°F).
