How to Lay Patio Stones Over Grass

Transform your backyard into an inviting outdoor oasis with a stunning patio. Here's a comprehensive guide to help you effortlessly lay patio stones over grass, ensuring a durable and visually appealing space.

1. Prepare the Ground

Mark the desired area for your patio and remove any existing grass using a sod cutter or shovel. Dig down 4-6 inches, ensuring the base is level and free of any debris. Compact the soil using a plate compactor or hand tamper.

2. Lay the Base Layer

Spread a 2-4 inch layer of compacted gravel or crushed stone over the excavated area. This base layer provides a solid foundation for the patio stones and prevents weed growth.

3. Install Edging

Define the perimeter of your patio with edging material such as pavers, plastic edging, or concrete. This helps keep the patio stones in place and prevents them from shifting.

4. Create a Leveling Bed

Spread a layer of sand, paver base, or screenings over the base layer. Screed the material flat using a straight edge to create a level surface. This bed will support and level the patio stones.

5. Lay the Patio Stones

Place the patio stones on the leveling bed, starting from one corner and working your way out. Use a rubber mallet to gently tap the stones into place, ensuring they are level with the surrounding stones. Maintain a consistent gap between the stones for proper drainage.

6. Fill the Gaps

Once all the patio stones are laid, fill the gaps between them with polymeric sand. This sand sets hard, preventing weeds and insects from growing within the joints. Work the sand into the gaps using a broom or brush, then spray it with water to activate the bonding agent.

7. Compact and Seal

Use a plate compactor or hand tamper to compact the patio stones and firm up the sand joints. If desired, apply a patio stone sealer to protect the surface from stains and weathering. Allow the sealer to dry thoroughly before using the patio.

Tips:

Use a variety of stone sizes and shapes to create visual interest.
Lay the stones slightly sloped towards the edges for proper drainage.
Avoid stepping on the edges of the patio stones to prevent chipping or cracking.
Clean the patio regularly to maintain its appearance.
If necessary, lift and relay any uneven or settled stones to ensure a smooth surface.

With careful planning and execution, you can create a beautiful and durable patio over grass that will enhance your outdoor living space for years to come.
