Installing Flagstone Walkway.

Laying flagstone patios in stone dust or sand, instead of mortar or concrete, is known as dry-set or sand-set. Dry production is much simpler for do-it-yourselfers because you could build directly on the ground, at the same time as mortared stone requires a concrete slab basis to prevent cracking in the mortar. For a long-lasting set up, a dry-set stone patio does want a foundation, although. It’s nice to start with several inches of compacted gravel, accompanied by using a layer of stone dust, also known as decomposed granite, or DG

The DG is pulverized stone and includes small portions along with gravel-length and sand-size debris. The variant in particle sizes permits the fabric to compact well. And even as it is nonetheless unfastened, you may use it to degree the stones, simply as you’ll with sand. You can purchase flagstone and DG at neighborhood stone yards and landscaping materials suppliers.

When selecting stone for the mission, pick the biggest stones you may maneuver by means of hand, and choose them for regular thickness and appearance. The stones must be at least 1 1/2 inches thick for power; 2 inches thick is better. Note that “flagstone” simply describes the stones’ wide, flat shape; flagstone comes in many one-of-a-kind types of stone.

Mark the Patio Edges
Set up mason’s traces to represent the fringe of the patio. Drive stakes at each corner, about 2 ft beyond the sides of the patio perimeter. Tie a mason’s line to opposing pairs of stakes to create a rectangular or square layout (use a square layout if the patio will be circular). You may have a complete of four strings; the points wherein the strings intersect represent the corners of the patio area. This format technique permits you to excavate and put together the complete patio vicinity while not having to transport the stakes.

Square up the Layout
Confirm that the string format is square by measuring diagonally between opposing
corners (in which the strings meet); the format is square when the diagonal
measurements are equal. Adjust the positions of the stakes, as wished, to square the layout.

Slope the Layout Strings
Level and slope the strings primarily based on the placement of the patio: The patio surface must be degree from side to side (usually parallel to the residence) and have to slope down and faraway from the residence from quit to cease at a charge of approximately 2 inches in step with 10 linear toes. For example, if the patio is 10 feet long, it will likely be 2 inches higher on the house cease than at the opposite give up. This guarantees that surface water drains faraway from the residence (or other systems).

To stage and slope the strings, vicinity a line level on every layout string and modify one quit of the string up or down, as wanted, so the road is perfectly degree, then tie off the string. Keep in mind that all of the strings need to be at the equal peak. Then, readjust the 2 strings walking down the perimeters of the patio to set the best slope. For a 10-foot-long patio, lower the strings 2 inches at the stakes on the decrease cease of the patio. Finally, regulate the perpendicular string on the decrease give up of the patio so it’s miles even with ends of the sloped strings.

Excavate the Patio Area
Remove all grass and other vegetation within the patio area (defined via the strings), then excavate the soil to a depth of 6 inches plus the thickness of the flagstone. For instance, if the flagstone is 2 inches thick, excavate a total of 8 inches. This is to make the patio flush with the surrounding floor; you may dig much less deep in case you want the stones to lie better than the ground.

Measure down from the strings to gauge the excavation depth. It’s normally simplest to dig to full intensity proper below the strings, then clean out the soil in between, checking with a protracted, straight 2×4 and a degree to ensure the floor is level backward and forward (it might not be level from stop to give up due to the slope). Tamp the soil with a hand tamp or a rented plate compactor.

Install the Gravel Base
Add a -inch layer of compactible gravel over the patio vicinity. Rake the gravel clean and stage, then tamp it very well. Add two greater inches, then easy and tamp. As with the excavation, measure down from the strings to gauge the thickness of the gravel and to preserve the proper slope.

Add the DG Layer
Add a 2-inch layer of decomposed granite over the gravel base. Rake the DG smooth, and degree it facet-to-facet with the long board and degree. Tamp the layer thoroughly. Remove the stakes and mason’s traces.

Organize the Stones
Stack or lay out the stones you’ll use for the patio floor on a broad, flat place, consisting of the encircling grass or a driveway. Arrange the pieces with the aid of size and shape so that you can pick them conveniently as you lay them into the patio.

Lay the Patio Stones
Place the stones onto the DG surface, starting at one stop and working closer to the alternative. Place the stones as close together as favored. You will fill the gaps later with sand, gravel, or even soil and grass or different flowers. Vary the scale, shape, and coloring of stones for a random pattern, which seems most herbal.

Level the Stones
Level every stone, as wished, by means of adding or eliminating DG below the stone. Each stone ought to be solid and at the equal top as the surrounding stones. Stone edges that stick up create tripping dangers.

Fill the Gaps
Fill the gaps among stones with sand, DG, or gravel. Sweep the cloth across the patio with a broom to push it in to the cracks. Spray the patio with a garden hose to settle the fill cloth, then sweep greater filler throughout the stones to fill the gaps as favored. Alternatively, you may fill the gaps with a potting soil mix and plant grass or traffic-tolerant ground cowl plants between stones.
