Solid granite steps installation with cobblestone landing in South Portland, Maine.

Four solid granite steps and a cobblestone landing are installed in South Portland, Maine.
The original failed concrete steps are demolished. The debris is removed. The site is excavated. Two steel reinforced concrete pads are formed and poured. The first steel reinforced concrete pad acts as a base for the cobblestone landing as well as a retaining wall that abuts the back of the solid granite steps. The retaining wall section of the pad will prevent the steps from being moved by the frost as well as a solid structure for the back of the steps to meet. The second pad will be a base for the steps. Next the granite steps are delivered and set on the ground to be cut to match the dimension of the original steps. The solid granite steps are then carefully set in place along with solid granite risers. A stone dust base is installed upon the landing’s concrete base. The dust will act as drainage for the landing as well as proper grading. It will also serve as buffer so that the landing properly meets both the top granite step and the bottom of the existing wooden steps. The cobblestones are first laid out to determine the best symmetrical pattern. Measurements and marking of the cobblestones is done before the stones are cut to the appropriate size. The cobblestones are then set upon the landing. Next the joints are filled with stone dust. There are quite a few other tasks involved. This is not a simple task by any means and should only be left to qualified professionals.
