No physical or mechanical tests were performed, nevertheless, results of Strohmeyer (2003) and Grimm (2018) were considered (Tables 2 and 3).

Kösseine Granite shows a very good behavior against atmospheric agents, directly related to its physical properties: very low porosity, low water absorption, low water uptake coefficient and permeability. These properties show that the rock is practically impermeable, and consequently extremely stable to weathering conditions.

Mechanical properties for Kösseine Granite are typical of granitic rocks, even slightly higher. Comparing its UCS (uniaxial compressive strength) values to those of the statistical study of Mosch (2008), it can be observed that they are above the median. Flexural strength is also above the median of Mosch (2008), but the indirect tension is slightly below this parameter.

Abrasion resistance values are slightly higher than those reported by Morales Demarco (2012) for Uruguayan granitic rocks, but in the range of values given by Siegesmund & Snethlage (2011).
