Project Description

An im­port­ant share of Ro­man walls are built in the tech­nique of ver­tic­ally-layered ma­sonry. The out­side wall ele­ments are made of tailored stone work and the in­side is filled with rubble and some bind­er. This is the case for the am­phi­theatre of AUGUSTA RAUR­ICA. A com­mon prob­lem for this build­ing tech­nique is the de­tach­ment of the out­side walls due to struc­tur­al move­ments and wa­ter in­tru­sion. If these walls are not sta­bil­ized in time, they can fail all to­geth­er­.

Dur­ing an in­ter­ven­tion the joint-­work was thor­oughly re­paired and a grout - based on fine quartz-sand, lime, and highly re­act­ive metaka­ol­in - was in­jec­ted in the void­s. The work was part of a train­ing and co­oper­a­tion ef­fort with the work­ers of the site.
