Grout hole means hole drilled in rock and used for injection of grout mixture under pressure for the sealing of permeable zones in the bed rock. Grouting of base plates can be accomplished for common base-plate sizes without the need for grout holes. Two grout holes may be required for very large plates or long rectangular plates. This drawing includes detail of group holes for contact grouting and details grout holes for pressure grouting. For more details and information download the drawing file.
