The church in Gyöngyöshalászi showed defects related to uneven subsidence of the construction due to overloading of the subsoil. There were cracks in the church constructions due to the subsidence of the foundations.

In order to correct the defective state, micropiling of the foundations was proposed, which transferred the load into deeper more stable soil. Self drilling micropiles R32N were used, grouted with polyurethane grouting resin GEOPUR.

In addition, undergrouting of the foundations was performed in order to "widen" the existing foundation to 2,1m. Undergrouting was done using grouting tubes and grouting resin GEOPUR.
