The wall is built in two wythes or tiers and can be safely built up to 3'; for a wall above 3', steel reinforcement is required. Reinforcing can be either rods inserted into the group after it has stiffened slightly or ties laid across two wythes to help hold them together. If you are panning to build a wall more than 3' high, it is best to consult your local building codes for exact specifications and techniques.
