ULO using colloidal mixers with high shear action has been able to successfully provide grouting services, to inject shapes and forms, for the past 50 odd years.
Non structural grouting is normally a neat cement mix with a specific gravity of 1.90 to max. of 1.98. These mix formulations thoroughly being mixed in a colloidal mixer are able to provide a dense material like paste, which in turn has stood the test of time, whereby no previously mixed and pumped project has been replaced due to failure over the past 50 years.
