Preparing a base for pavers for your backyard terrace and walkway paving is a crucial step to ensure a stable, level, and long-lasting surface. Here's a step-by-step guide to help you with the process:

Materials you'll need:

Pavers of your choice
Crushed rock or road base
River sand
Timber stakes
String line
Spirit level
Compactor or hand tamper
Rubber mallet
Shovel
Wheelbarrow
Step 1: Mark and Clear the Area
Mark the outline of your terrace and walkway using timber stakes and a string line. Clear any vegetation, debris, or existing surface from the marked area.

Step 2: Excavate the Area
Using a shovel, dig out the marked area to a depth that accommodates the thickness of your pavers plus the required depth of the base. Typically, you'll need around 4-6 inches of depth for the base.

Step 3: Compact the Soil
Use a compactor or hand tamper to compact the soil thoroughly. This step ensures a stable foundation for the pavers and helps prevent settling over time.

Step 4: Lay a Geotextile Fabric (Optional)
For additional stability and to prevent weed growth, you can lay a geotextile fabric over the compacted soil before adding the base materials.

Step 5: Add Crushed Rock/Base Material
Pour a layer of crushed rock or road base into the excavated area. Spread it evenly using a rake and ensure a uniform thickness across the entire area.

Step 6: Compact the Base Material
Using the compactor or hand tamper, compact the base material to create a solid and level surface. Check for levelness using a spirit level frequently during this process.

Step 7: Add River Sand
Once the base is compacted, spread a layer of river sand over the compacted base. This will create a smooth and level surface for laying the pavers.

Step 8: Lay the Pavers
Start laying the pavers from one corner of the terrace or walkway and work your way outward. Tap each paver gently into place with a rubber mallet to ensure they are level and well-seated in the sand.

Step 9: Check for Levelness
Regularly check the levelness of the pavers using a spirit level to ensure a smooth and even surface.

Step 10: Fill the Gaps
Fill the gaps between the pavers with more river sand, and use a broom to sweep the sand into the joints. This will help secure the pavers in place and prevent movement.
