  As an extension of a thin-shell, we adopt a single parametric plane-symmetric
Kasner-type spacetime to represent an exact thick-plate. This naturally extends
the domain wall spacetime to a domain thick-wall case. Physical properties of
such a plate with symmetry axis $z$ and thickness $0\leq z\leq z_{0}$ are
investigated. Geodesic analysis determines the possibility of a Newtonian-like
fall, namely with constant negative acceleration as it is near the Earth's
surface. This restricts the Kasner-like exponents to a finely-tuned set, which
together with the thickness and energy parameter determine the G-force of the
plate. In contrast to the inverse square law, the escape velocity of the
thick-shell is unbounded. The metric is regular everywhere but expectedly the
energy-momentum of the thick-plate remains problematic.
