Darby ES






Darby ES involves resurfacing of a raised playground with retaining walls around the perimeter.  During our initial visit of the site, we noticed cracks and spalling on the retaining wall where the fence posts are located.  Corrosion was present at the base of the posts due to the storm runoff that spilled onto the adjacent sidewalks.  Corrosion expanded the base of the posts, resulting in spalled concrete.  Along with a resurfacing plan to properly divert water onto new catch basins, Engineering Alignment Systems provided repair details for the concrete retaining wall.  Damaged sections of the concrete wall were replaced and new posts were installed.  A concrete cap was provided to raise the wall height and prevent water runoff onto the sidewalk.
