Curtain grouting is carried out to make the rock mass less permeable at a given line (or two or three parallel rows). Depth of grout curtain holes vary from a few meters to more than 150 m.

Consolidation grouting aims to improve rock mass (foundation) strength, permeability and reduce its deformability and executed in an area rather than a line. Usually, grout holes for consolidation grouting are less than 15 m deep.

if your grout line is less than 1/4" you use smooth grout, above that you use sanded grout.

The old grout can be cut out. The mist efficient way is with an oscillating tool with a grout blade. After the old grout is removed then new grout can be installed. This is a time consuming project.

Grout is not toxic. Grout sealers and adhesives can be toxic but not the grout itself. Tami Barker www.mosaicforms.com Mosaic Art Instructor and Creator
