The evolution of the corrosion interface separating the uncorroded concrete part and the corroded part of a partially wet concrete wall of a pipe under the influence of hydrogen sulfide can be modelled by a moving boundary problem for three coupled one-dimensional diffusion equations. We show that the problem formulated via weak solutions is well-posed. The function describing the position of the moving boundary belongs to $W^{1,\infty}(\R^+)$. The paper generalizes previous results by relaxing the assumptions and by providing global weak solutions instead of local ones.
