A decomposed granite patio is an excellent choice for outdoor landscaping. Not only does it bring out the natural beauty of your patio, decomposed granite is also durable and can last for years. Making a decomposed granite patio is relatively easy by following this procedure.

Step 1 – Get the Work Area Ready

Clear area from wood debris and remove all grasses. Dig out lumps, tree branches, or big stumps or roots around. Don’t let any materials that rot remain in the area since this would sink or cave in and later on affect the level of the patio. Hit the soil using plate compactor to ensure loose soil is compacted. Put stakes into the four corners of the area and another at the center. Tie the nylon cord to serve as a guide. Measure 6-inch from the lowest point and tie the cord.

Step 2 – Lay down the Base

Pour gravel into the area and cover up to the level of the nylon cord. This will ensure you have covered enough level as a base for the patio. Use the compactor again to level the area flat. Don’t leave any loose gravel around. Firm up the surface. Adjust nylon cord to 3-inches above the compacted gravel surface. Lay down the root barrier fabric on top of the gravel surface. Cover the entire area. This will be helpful later to prevent weeds from thriving around.

Step 3 – Apply Decomposed Granite

Pour the decomposed granite into the compacted gravel surface up to the 3-inch level of the nylon cord. Run the compactor again across the whole area. Check the central part of the patio. This should be higher than any other side of the whole area. This is very important to prevent water from accumulating during wet season as the granite is slow to absorb water. Make a slight slope near the edges of the patio; where you would be putting the edging as a next step.

Step 4 – Apply Edging Around

Stand the flat board 2-inches off the entire edge of the patio. Hammer the stakes into the soil at the outer side to support it. Mix cement and tinting material and pour into the edge of the decomposed granite. Tap the flat board to let the cement settle and fill into the crevice. This preserves the patio from crumbling at its side aside from the added aesthetics to the overall appearance of the project.

Step 5 – Finishing up

Let the cement dry up by 48-hours. Remove the stakes and flat board to reveal the edging around the patio. Fill in the gaps with soil and your preferred lawn grass. Clear up the remains of the area and the equipment and tools used. Maintain the area by clearing it regularly from branches and debris so the patio will last for many years to come.
