Terracol System

Terracol grout is a very low-viscosity, chemical grout system used for ground consolidation and stabilization of foundations and footings located on fine to medium sands.

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:

  • Terracol Component A - Colloidal silica suspension in the form of nano-particles

  • Terracol Component B - Hardener

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).

Advantages

  1. 1 Adaptable
  2. 2 Very low viscosity
  3. 3 Safe

Features

  • Adjustable gel time, by varying proportions of hardener allows for project-specific formulations

  • Material is friendly to the environment

  • 5 to 10 cps enables maximum strata penetration, minimal product waste
