  An example is given of a plane topological torsion defect representing a
cosmic wall double wall in teleparallel gravity.The parallel planar walls
undergone a repulsive gravitational force due to Cartan torsion.This is the
first example of a non-Riemannian double cosmic wall.It is shown that the walls
oscillate with a speed that depends on torsion and on the surface density of
the wall.Cartan torsion acts also as a damping force reducing the speed of
oscillation when it is stronger.
