rock grouting
what it is:
Rock grouting is the injection of specially formulated cement-based mixes into the ground to improve its strength or reduce permeability.
how it works:
It’s most commonly performed by drilling holes into the underlying rock to intercept open cracks, joints, fissures or cavities, then pumping under pressure balanced and stabilized grout mixes using a combination of cement, water, and additives. For larger, more complex projects, enhanced quality control is available through real-time computer monitored grouting software called GROUT I.T.
why you need it:
Rock grouting can be used to decrease water flow through fractured rock, plus it can be performed in areas with space constraints. It is mostly used for dams, tunnels, reservoirs and shafts.
