In this study the hydraulic conductivity of two different soils that are used as an earthen roof on

traditional houses in Kemaliye are examined. Kemaliye and its villages are situated at the

intersection of Anatolia's various residential regions; have their architectural design features

elements of local culture. The abandoning of housing for different reasons like migration over time

is likely to cause damages, especially in building walls and earthen roofs that needs regular

maintenance. The soils having local names as Gavcin and Yaşkuru are taken from Kemaliye region

to perform laboratory tests. Index properties of soils are obtained by standard laboratory tests. The

hydraulic conductivity of compacted soils are measured under constant pressure. It is aimed to

decreasing the hydraulic conductivity of soil for reducing the maintenance of earthen roof. For this

reason, some additives like natural hydraulic lime, fly ash, granulated blast furnace slag are used to

get impermeable soils. There are limited studies about mineral additive effects on hydraulic

conductivity. As a result; it is aimed to prevent infiltration into the earthen roof due to precipitation

and decrease maintenance of roof by reducing the permeability of two different soils which are

used as roof materials in the traditional Kemaliye houses.
