Summary: In this article we study the behaviour near the boundary for weak solutions of the system $$ u''-\mu\Delta u-(\lambda +\mu )\nabla (\alpha (x)\,{\rm div}\, u)=h\,, $$ with $u(x,t)=0$ on the boundary of a domain $\Omega\in {\bf R}^n$, and $u(x,0)=u^0, u'(x,0)=u^1$ in $\Omega$. We show that the Sobolev norm of the solution in an $\varepsilon$-neighbourhood of the boundary can be estimated independently of $\varepsilon$.
