Abstract
A multi-component grouting system having at least one component wherein the active ingredient is contained in the dispersed phase of a water-in-oil emulsion, the oil providing an effective barrier against mixing of the components thereby enabling the components to be stored indefinitely in direct contact. The components may advantageously be encapsulated in a single compartment frangible casing for insertion into drillholes in rock. The grouting systems may be based on compositions comprising hardenable resins, Portland cement, Plaster of Paris, zinc oxide/zinc chloride, or sodium silicate. By eliminating the usual plastics film barrier between the grouting system components, intimate mixing of the components in a drillhole by rotation of the bolt to be fixed inthe drillhole may be more easily and reliably effected.
