Soon after carrying out the Original tremie grouting, strain grouting is concluded concomitantly With all the lifting of your casing from the bond zone by way of a pre-mounted tube.
There exists also a heightened price of production putting in just one bigger bar versus scaled-down bundled bars.
Is usually combined with other tactics to fulfill exclusive or intricate project needs Price tag-successfully and effectively
