Abstract:
A method of limiting or reducing permeability of a matrix to liquid and/or gas inflow is described. The method includes limiting inflow of water, liquid and/or gas into passages such as cavities, fissures, voids and the like, encountered in formations such as geological formations though can be used to form barriers to water, liquid or gas flow through a matrix. The method includes steps of measuring one or more parameters relating to the matrix and selecting one or more components of a multi-component sealing composition with reference to the measured parameters. The selected components are introduced into the matrix where it is set or coagulated in a non-exothermic or low exothermic process to form a seal barrier. Also disclosed is a sealing composition comprising a coagulable polymer emulsion or colloid contactable with at least one selected additive which interacts with the polymer emulsion or colloid to form a coagulated mass for forming a sealing barrier in a non-exothermic or low exothermic setting process in which the polymer emulsion or colloid contains, prior to purposeful coagulation due to interaction with the selected additive, particles having a size distribution smaller than for Portland cement.

Claim (Index 21):
A method of limiting or reducing permeability of a matrix to reduce or limit liquid or gas flow within the matrix with a sealing composition comprising a grout component; and a grout curing agent wherein a portion of the grout component is mixed with a portion of grout curing agent, the ratio of grout component to curing agent being selected with reference to one or more parameters relating to said matrix, wherein the combined grout component and curing agent are introduced into said passage where it is set or coagulated in a non-exothermic or low exothermic process to form a seal barrier, whereby rate of curing or setting of said grout component in said matrix is controlled or varied by modifying the ratio of grout component to curing agent.
