After watching the video below you will be surprised how easy it is to create a curved brick step! Just follow mason’s instructions in this video and he will show you how to achieve the half-round arch for front doorsteps. He marks the curve by rotating a stick and laying down bricks at the edge of that stick.
The first marking of the first line of bricks is going to determine the final shape of that step. Once the first step of marking is done, it will be filled with concrete and brick followed by the second step. The second step will be smaller than first, but they will work on the same principle in laying the bricks and filling the internal area with more bricks and concrete.
