The retaining wall was stabilized using R32N anchors grouted with polyurethane grouting material GEOPUR.

Total of 10 pc of anchors of 6 m length were drilled and grouted. Anchors were drilled under an angle of 30° from the horizontal level, in order to get the root of the anchor into solid rock.

Cracks in the retaining wall were repaired by the technology of "sewing", i.e. by reinforced grouting.

In accordance with the requirements, anchors were tested for their bearing capacity by a pulling test. The required bearing capacity was 70 kN. The anchors were tested up to 150 kN during the test, without any damage.
