The floor was reconstructed due to presence of a problematic cinder fill material below, showing the character of swelling and thus lifting up the floor. The new floor was constructed as a "floating" floor on micropiles. Self drilling micropiles R38 grouted with polyurethane resin GEOPUR were used. We delivered also statical assessment and calculation. 

In total 47 pc of micropiles were installed of average length 9 m.
