Actually, you dont want to use sand because youll need to walk on this layer a lot, and as you know, sand moves when you walk on it. So instead, youll want to use some crushed rock that includes the screenings.

Where Im from, the best stuff to use is called Decomposed Granite . This stuff looks similar to sand, but it packs down much better so you can walk on it. Since its composed of both bigger pieces of sand and fine dust, its able to pack down similar to dirt, but its still easy to level out, and weeds have a hard time growing in it.

Since this is the final layer before you start laying stones, youll want to make sure its flat and graded properly. So, use a mason line tied between stakes in the ground and a line level to set the grading just right and ensure a flat patio.

Once its level, spray with the hose to get it damp and pack it down thoroughly. Level again if you have to.

Now, how will you count the depth?

  • For foot traffic count 4 to 6 depth of base material
  • For vehicles, traffic counts up to 12 depth of base depending on the sub-base material. For soft clay land, it is more profound than harder soil.
  • Similarly, cold-weather regions demand a thicker
  • Count 1 to 1.5 sand bed on the top of the compact base
  • Add the thickness of the paving stones you have selected. You can ask your supplier. Generally, it is in a range of 2 3/8 to 3 1/8
  • Now, take the sum of the thickness of all layers and excavate the same depth following the marks you have made on stacks. You must measure the depth from the marks to assure the slope you have defined.
  • Cover 6 to 12 space beyond boundaries for installation of edge restraints.
  • Edging will save materials and stones from scattering due to load/pressure.
  • Level the surface of the bottom soil once you achieve the desired depth to fill up the uneven Use the appropriate amount of water to wet the sub-soil and compact it with the compactor.

You will find an overall picture as mentioned in the picture above.

How To Harden Sand Between Pavers

Whats the best solution when the question is: -how do you harden sand between pavers?

Regular sand, on its own, despite serving this purpose very well, doesnt harden enough. The material does fill gaps between pavers and help lock the individual blocks in place quite well, so they dont shift. But, regular sand tends to become soft when wet.

However, when sealing the pavers surface, the substance also comes into contact with the sand. When this meeting occurs, it causes the two materials to form an alloy, similar to mortar. Thus, effectively hardening the sand and helping to fix it.

If possible, use irregular, sharp-grained sand, as they have sharp edges and bind together better.

Polymeric sand often comes into play at the end of a landscape paving project, including projects involving concrete pavers, brick pavers, and stone pavers. The sand helps to secure the pavers into a uniform and durable surface.

Perennials That Fit In Tight Spaces

Choose the perfect perennial for your situation based on its appearance and the growing conditions in the planting location. Next, plant it at your chosen site and monitor it to ensure that it has all that it needs to thrive.

Note that when pressure cleaning driveway and pavers, you will probably uproot and destroy any plants you grow around your bricks.

You can either take them out and clean them away from their original location or hand-wash them in place so the plants are not harmed by strong bursts of water.

What Happens If Polymeric Sand Gets Rained On

Once the polymeric sand has set up, heavy rain wont hurt it. But if you have just finished applying polymeric sand and it hasnt yet set up like in the first 24 to 48 hours then youll need to protect your patio from a downpour. Use a tarp or plastic sheet.

Polymeric sand should always be installed on a bone-dry patio, so make sure you pick a stretch of good weather. If you leave polymeric sand on top of slabs , then once it rains you may have sand permanently stuck to the top of the pavers.

Filling Pavers With Moss


Pull any existing weeds and scrape out the filling between pavers using a spade, if you are working with an existing patio.


Fill in the space between pavers using garden soil. Only fill the spaces about half full, leaving enough room to transplant the moss.


Gather live moss growing around your property, carefully removing it from the ground along with some of the soil it is growing in, using a small trowel.


Moisten the soil between the pavers and the underside of the moss sections you have gathered using water from the garden hose.


Pack the moss firmly into the spaces between the pavers, using your trowel to cut strips of moss from larger pieces, if necessary. Tamp down the moss by stepping on it.


Wet down the moss using the garden hose and water it once a day for three weeks or so, until the moss becomes established. After the moss has settled in you may only need to water it when it begins to dry out or lose its color.

Mossy Rockfoil A Fussy Perennial

This plant grows in thick mounds or mats of bright green leaves on slender, purple-tinged stalks. Heading into early summer, it produces tiny cupped flowers of pink, purple, or white.

Treat rockfoils seeds to cold stratification, a process that involves both moist and cold conditions. Afterward, the plant can take two to three years to bloom. After mossy rockfoil blooms, its mounds often die in the middle.

To prevent this issue, pour sandy grit around the plant to retain moisture, or divide mature clumps. Choose a cool, shady site with moist, loamy soil.

Water rockfoil near its roots twice a week in the summer. Mix in compost during planting and apply a layer of mulch.

What Do You Put In Gaps Between Paving Slabs

To fill in the gaps between the slabs, either Kiln Dried Sand or a jointing compound can be used. This prevents any potential movement, but still allows water to drain. We recommend Sika Pave Fix Plus as a Jointing Compound as it is quick and easy to apply whilst giving long lasting results.

Using Polymeric Sand Between The Bricks/paving Stones

Filling flagstone patio cracks

Polymeric sand is a blend of properly graded fine sand and a binder compound that is specially formulated for filling in the joints between bricks, pavers and natural stones for hardscapes such as patios, driveways and walkways. Polymeric sand was invented by Techniseal in 1999, and it has improved;the installation and maintenance of brick and stone hardscapes.

After the paving stone surfaces have been cleaned with a power washer its best to let them dry completely before applying the polymeric sand. ;If its wet out and you try sweeping the sand into the cracks it just creates a big mess and takes longer. ;This process is best done on a nice day when the driveway is DRY but only AFTER its already been power washed. ;You do not want to apply the sand and power wash after as this will be a complete waste of some very expensive sand!

After the polymeric sand has been carefully swept into the cracks between the bricks or paving stones and compacted, the driveway can be sprayed down with water. ;The water will be absorbed by the polymeric sand and it will then harden in between the cracks. ;The hardened;sand will resist weed growth in between the paving stones for quite some time, will help hold the bricks in place, and it also helps stop burrowing insects from making nests under your paving stones.

How To Repair A Crack In A Flagstone Patio

21 September, 2017

Flagstones form a sturdy base for a patio, and the variety of sizes, shapes and colors allow the installer to create unique patterns and designs. As reliable as these stones are, weathering and time will eventually wear down the stones, leading to cracks in the stones themselves. Patch cracks in flagstones with cement or concrete patches and mortar that will seal up the damage and stop your flagstones from looking broken and worn.

Use a wire brush to scrape away loosened or pointed edges of the crack. Sweep or vacuum up debris with a wet/dry vacuum.

Wear goggles to protect yourself from shrapnel and use a chisel and hammer to undercut the crack. Expand the crack to at least an inch deep. Chisel the bottom of the crack so it looks like an upside down V, with the bottom wider than the top. This will help spread the patching material into the crack.

Sweep or vacuum all debris from chiseling so the area is free of dust. Dampen the crack and the surrounding edges with clean water, but do not let water settle into the crack. There should be no standing water in your repair area.

  • Use a wire brush to scrape away loosened or pointed edges of the crack.
  • Dampen the crack and the surrounding edges with clean water, but do not let water settle into the crack.
  • Mix 3 parts sand and 1½ parts Portland cement with enough water to form a thick, creamy mortar.
  • Spread the cement mixture into the crack, using a mason’s trowel.

Manufactured Concrete Cobbles That Come In Mats

Paver patios are definitely practical but laying each paver by hand, one by one gets really annoying quickly. You can make things easier by opting for the more time-saving and practical alternative: manufactured concrete cobbles that come in the form of mats, very much like mosaic backsplash tiles. Theyre super easy to install. Once youve arranged all the mats and filled all the gaps, you just pour grout over everything and you spread it evenly.
