– Capstone
– Gravel
– Landscape fabric
– Wood stakes
– Wooden string line

Steps to Follow
Here are the steps to follow when building a retaining wall on a sloped hill:
Step 1: Plan and Layout
The first step is to plan and layout your retaining wall. Measure the length and height of the wall and determine the location and elevation of the wall. Use wooden stakes and a wooden string line to mark the location of the wall.
Step 2: Excavate
Excavate the area where you want to build your retaining wall. Dig a trench that is at least twice the width of the retaining wall and deep enough to accommodate the first course of blocks. Make sure the bottom of the trench is level.
Step 3: Lay the First Course of Blocks
Using masonry sand for leveling, lay the first course of blocks in the trench, making sure they are level and tightly fitted. Use a level to ensure the blocks are level.
Step 4: Add Gravel and Landscape Fabric
Add a layer of gravel behind the first course of blocks and cover it with landscape fabric. This will help to facilitate drainage and prevent soil erosion.
Step 5: Lay the Subsequent Courses
For the subsequent courses, use masonry sand to level and align the blocks. Stagger the blocks like bricks to create a stable and strong wall. Use a level to ensure the blocks are level and straight.
Step 6: Backfill and Compact
After laying each course, backfill the area behind the wall with gravel and compact it using a plate compactor. This will help to stabilize the wall and prevent soil erosion.
Step 7: Cap the Wall
Once you have laid all the courses, cap the wall with capstone. Capstone helps to protect the wall from weathering and erosion and gives it a finished look.
Step 8: Finish the Area
After you have finished building the retaining wall, finish the area around it. You can add plants, mulch, or do any other landscaping that you desire.
