Clean the ground surface of the site. And then establish the necessary level lines.
Lay ACETube® on the designated position and fix it in place.
Insert filling pipe into the filling port of the ACETube® and tie it properly. Then fill the ACETube® with sand-water mixture.
After water being filtered out, check to see whether the filled height reaches the designed height; if not, then continue with the filling process until it matches.
Seal the filling port after the ACETube® reaches its designed height, to keep the filled sand inside the ACETube®.
Fill the gap between ACETube® and the concrete wall with backfill, and then compact it.
Repeat step 2 to 5 to achieve the designed range.
