Grouting

The principle of grouting is to fill the loose pores of the rock environment with a liquid mixture (based on cement or polyurethane resins), which after a certain period of time solidifies and seals up or possibly strengthens the defined space. The effect of grouting depends on the arrangement of the grouting system of boreholes and on the composition of the grouting mixture.

 

Firming grouting is carried out under the foundations of the buildings (bridges, retaining walls, historical objects) whereas sealing grouting is used in the dams of waterworks and with sealing of municipal solid waste dumps.
