ABSTRACT

In the present paper a grouting technique was studied in order to protect the
buried monuments against the presence of the ground water. Krisis Macedonian
Tombs in N. Greece was used as a pilot example for study, given that it is buried
in loose sediments where the aquifer overflows their floors. Although the proposed
method is expensive, it establishes permanent drainage conditions regarding to
pumping. The purpose of this method is to create an impervious shell, which
isolates the floor and the walls of the tomb, so as the monument to be impervious.
In this paper the type of the chemical grout as well as the length and the number of
necessary boreholes were calculated taking into account the penetration of the
grout and the orientation of the boreholes. The number of the boreholes that is
needed to impermeate the building that includes the tomb is 46 and for the tomb it
self is 24. The total length of boreholes for the first case is 750,54m and for the
other one is 297,62m. The grout mixes are colloidal solutions or polymers such as
silica or ligno chrome gels, tannins, organic colloids on polyurethane, or pure
chemical solutions such as acrylamides, aminoplast or phenoplast, depending the
grain-size changes of the soil.
