Parapets are built on flat concrete decks. The height of the walls is three to four feet high. They are built into the edge to ensure flat roofing. This is done to prevent people from falling off the concrete slab. The construction uses similar wall materials as the building. This includes brick, concrete, glass, aluminum, masonry, or steel. Steel railings can also be used as a parapet. The walls have a stone finish for the weather.
The parapet is raised with strong mortar. Since the walls are on the open roof, they must withstand the pressures of wind or weather. Depending on the type of concrete slab, solid wall materials must be used. The flat roof floor finish is protected by the parapet. Also the drainage channels inside the roof are protected by these walls. After the construction of these short walls, the waterproofing of the flat roof is carried out.
The position of the parapet is marked around the entire flat roof. Bare wall thickness is a minimum of eight inches. A layer of moisture-proof bitumen is laid first. This is to prevent moisture from penetrating the ceiling below. The masonry of the wall is normally built as in other plants. During the casting of the concrete slab, short columns are left to support the parapet. The iron frame of the wall hoop is attached to the columns.
After the parapet wall is ready, finishing can begin. The finishing stone is placed on it. This should be wider than the wall that includes the finishes. This should be at least ten inches wide. this will leave a one inch overhang on each side. The exterior part or facade must have a finish similar to the decoration of the building. The inner part is rendered. It is steel floated at the time of dust. Once dry, exterior paint is used to finish it off.
