Consolidating unstable cavities

Underground cavities can jeopardise the stability of existing or future structures. Whether natural or artificial (old quarries), these cavities must be consolidated.
Accessible cavities are consolidated via manual construction of masonry pillars.
Other cavities require backfill grouting including boring to access the empty zone.
