Figure 1
Typical foundation of the antique building (without or with basement).
Figure 2
Sources of the foundation load capacity deficiency: a) basement deepening, b) load increase.
Figure 3
Remedies used to increase the load capacity of the existing foundation: increase of the existing foundation dimension: a) horizontal, b) horizontal and vertical, c) pressure injection, d) micropiles installation, e) addition of the reinforced concrete foundation slab.

Proposed substitute foundation for benches, slab and soil between them.
