  Let $(X,B)$ be a log canonical pair and $\mathcal{V}$ be a finite set of
divisorial valuations with log discrepancy in $[0,1)$. We prove that there
exists a projective birational morphism $\pi \colon Y\rightarrow X$ so that the
exceptional divisors are $\mathbb{Q}$-Cartier and correspond to elements of
$\mathcal{V}$. We study how two such models are related. Moreover, we provide
an application to the study of deformations of log canonical singularities.
