Nothing supports a newly paved asphalt road or parking lot better than properly structured concrete curbs, islands and sidewalks. Southeastern Site Development’s flexibility is well suited to the site details of your next concrete project.
Our team will first dig a subgrade. A subgrade must prepared by excavating or filling to the required elevation of the bottom of the concrete. The subgrade shall be well drained and cleaned of all sod and organic material. Where necessary for the construction of ramps and drive approaches, the curb shall be cut for its full depth. Where necessary to cut or remove tree roots, adequate precautions shall be taken so as to protect exposed roots and preserve existing trees. Any material found to be unsuitable, such as muck, peat, marl, soft clay and other such materials subject to frost heaving, differential frost action, or if the material is unable to provide adequate support for surface improvements, is removed and replaced with granular material. All fills are then thoroughly compacted to the required grade.
The area between the sidewalk and curb is then graded and leveled to provide the required slope toward the curb or roadway. The area between the sidewalk and property line is also graded and leveled to meet the original ground surface.
