Setting pavers in sand involves carefully placing them on a prepared sand bed to create a level and durable surface. The key is to avoid disturbing the sand and ensure the pavers fit snugly together. Here's a step-by-step breakdown:
Preparing the Sand Bed
Before setting the pavers, you'll need a properly prepared sand bed:
- Excavation: Dig out the area where you want to place the pavers. The depth will depend on the paver thickness and the base materials (typically gravel and sand).
- Base Layer: Add a compacted gravel base for drainage and stability. This layer is crucial for preventing settling and shifting of the pavers over time.
- Sand Layer: Spread a layer of bedding sand (typically 1 inch thick) over the compacted gravel base. This sand layer will be your leveling medium.
- Leveling: Use screed pipes and a long, straight board (screed board) to create a smooth and level sand surface. Ensure the sand is compacted lightly.
Setting the Pavers
Here's the core process of setting the pavers:
- Placement: Carefully place each paver straight down onto the prepared sand bed. Avoid dragging the paver across the sand, as this will disturb the level surface.
- Snug Fit: Fit the pavers together snugly, maintaining consistent joint spacing. Joint spacing is critical for allowing proper drainage and sand infill.
- Avoid Stomping: Never stomp a paver into place. This can cause uneven settling and damage the paver. If a paver needs adjustment, gently lift it, add or remove sand beneath, and then replace it.
- Continuous Placement: Continue placing pavers until the entire area is covered. Periodically check the level and alignment using a level and string lines.
- Cutting (If Needed): At the edges, you may need to cut pavers to fit. Use a paver splitter or a circular saw with a diamond blade for clean, accurate cuts.
Final Steps
After all the pavers are set:
- Edge Restraints: Install edge restraints (plastic, metal, or concrete) around the perimeter of the paved area to prevent the pavers from shifting outwards over time.
- Sand Infill: Spread fine sand (polymeric sand is a good option) over the pavers and sweep it into the joints. This helps to lock the pavers together and prevent weed growth.
- Compaction: Use a plate compactor (with a protective pad to prevent scratching) to compact the pavers and further settle the sand into the joints.
- Final Sweep: Sweep away any excess sand from the surface.
- Water Activation (If Using Polymeric Sand): If you used polymeric sand, lightly water the paved area according to the manufacturer's instructions. The water activates the polymers in the sand, causing it to harden and create a more stable surface.
By following these steps, you can effectively set pavers in sand to create a beautiful and long-lasting patio, walkway, or driveway.
