Remove the center cap and cut along the marks. Place two caps on top of the wall, spaced so a third cap will fit tightly between their widest point. Using full size blocks in tight curves will create a gap between the courses. Set another cap on top of the first two caps in the center and mark where they overlap on the bottom of the center cap. Curves are sexy, though. Draw a line from the mark to the front corner. To build a flowing inside curve, butt the block end to end to match the smooth curve required on the project. For the. The final height of the wall will determine what the minimum radius at the base course must be. Base course radius for an outside curve on a 4 ft (1.2 m) tall 6° retaining wall. The above steps work for both inside and outside radiuses. Curved block retaining walls can be difficult, especially when they have a tight curve and you look at them very closely. Set the adjacent caps in place; Set the stone cap you need to cut on top so they overlap the adjacent caps. Make sure strength direction runs perpendicular to wall face. This will be the center of the curve. Mark the blocks or take note of the areas where there are voids in the grid placement. When placing geogrid along curved retaining walls, the geogrid should follow the back of the lip on the retaining wall block. The cap is made in a concrete form to fit the wall system.
