Gałecki Palace in Krotoszyn

Subsoil beneath a historic palace was reinforced using geopolymer injections, increasing load-bearing capacity to safely support roof reconstruction — completed in four days without structural intervention.

Object: Gałecki Palace
Location: Krotoszyn, Poland
Sector: Heritage / Historical buildings
Technology: Geopolymer injections under foundations
Products used: Georesin 350, 1C-Soil
Injection depth: Up to 1.3 m below foundation footings
Execution time: 4 days
Owner: State Primary Music School in Krotoszyn
Contractor: Geolift Polska Sp. z o.o.
Responsible person: Aleksander Krysiak

Problem

Planned roof reconstruction would increase loads on the palace foundations.

Cause

Geotechnical investigations showed the existing subsoil would respond poorly to higher loads, risking settlement.

Risk

Foundation settlement in a protected historic building, with high structural and conservation risk.

Solution

Targeted geopolymer injections performed directly beneath existing foundation footings
Compaction and reinforcement of weak soil layers along the full length of the foundations
Execution strictly aligned with conservation authority requirements
No excavation, no interference with the building structure

Execution & Results

Full foundation reinforcement completed in 4 days
Works limited to localized injection zones only
No structural modifications to the historic building
Significantly faster execution compared to traditional ground stabilization methods

Benefits

Fast implementation
Works do not interfere with other activities taking place inside the building
Significant reduction in foundation reinforcement costs
Long-term soil stability in complex geotechnical conditions

Historic buildings require measured, reversible and non-destructive solutions.

Geopolymer injection enables precise subsoil reinforcement while preserving the palace’s structural and cultural integrity.
