 After erection of RE Wall, the next step is to do backfilling. At every stage backfilling is required and also erection of panels is also done. Layer by layer geogrid is given and also geotextile is worn at the side of RE Wall joints. This process continues till the completion of top panels, i.e., RE Wall top.  So what's the use of backfilling? Or why this backfilling is done? To answer such these silly questions are, awkward. As this backfilling is done to fill up the foundation or to maintain the soil at the same level. But what, if this question is about inside the RE Wall. That is, inside RE Wall backfilling is going on, or done.  No need to worry about this. Because in every bridges, where the RE Wall work is going on, backfilling is done inside it. This is done so as to maintain the wall-to-wall distance proportionally, i.e., wall 1 & wall 2. In every RE Wall design, you will see that the vertical height is proportionally inclined. From wall 1 to opposite wall,...
