A study of the effects of compensation grouting on tunnel linings has started with support from Nishimatsu Construction.
You don't have to mess with gluing, grouting and other messy components of traditional flooring.
A case in point is the employment of hydraulic lime in place of Portland cement as grouting outside the cast-iron tubes used for lining tunnels made by the shield system.
The bases are either grouted with cement, or bolted to the foundations, but where cast column bases rest on masonry piers or footings any considerable grouting is not advisable.
The cap stones should always be brought to the most accurate bed possible, with grouting used as a thin cement and not as a backer.
