There are three types of stone variants in the Sedramic quarry:
- about 70% beige called Beige Dalmacija
- about 20% amber called Amber Dalmacija
- about 10% of roze called Roze Dalmacija
The total reserves of Sendramic stones are 2.200.000 m³
Physical-mechanical properties of the stone:

- St min 5.1 MPa
- St mean 8.1 MPa
Resistance to wear by scraping acc. to Boehm (HRN B.B8.015): As 15.4 cm³/50cm² - loss
Velocity of longitudinal waves: (HRN B.B8.121) 5909 m/s
Water absorption (HRM B.B8.010)*: U 0.212 mass %
Apparent density (HRM B.B8.032)* rm 2.654 t/m³
Real density (HRM B.B8.032)* Rg 2.710 t/m³
Level of density (HRM B.B8.032)* rm/rg 0.979
Porosity (HRN B.B8.032)* (1-rm/rg)x100 2.070 vol.%
Resistance to freezing (HRN B.B8.001) No. of cycles:25 resistant
Resistance to Na2SO4 crystallization (HRN B.B8.002) No. of cycles: 5 | 0.090 mass % - loss
After 5 cycles of treatment, there were no changes in appearance and the mass loss was insignificant - the stone is resistant.
