How do you apply polymeric sand without a compactor?
Polymer sand will help seal the gaps and keep the weeds growing. Spread evenly a layer of polymer sand on the entire area. Use a soft bristle broom and fill the gaps to their full depth. Do it until the joints are uniformly filled.
A lawn roller or hand tamper can be used to compact the moist soil, or you can walk over it.
An ordinary sledgehammer is a better hand-operated tool for tamping. Handle vertical, lift and drop, repeat. Doing a good job with one is tedious but quite possible if you prefer not to rent a powered plate compactor. For something like compacting around a fencepost, an iron digging bar can be used to compact.
Soil can be mechanically compacted by applying force with a roller, hoe or rammer. A roller looks like a drum aerator, minus the spikes. Pulling this weighted metal drum over the lawn crushes the soil. In a pinch, a heavily loaded wheelbarrow can do the same job.
Watering the surface will activate the polymers in the sand. You'll want to set your hose to the shower setting and shower water at a height of 4ft. Wait no longer than 3-4 minutes and don't spray too large of an area at once. Important: You should never allow the surface to dry out during the watering process.

Ideally a small wacker plate would be beneficial to compact it but a hand tamp will do an ok job although you'll have arms like popeye when you finish.
You need a plate compactor for every paving installation project. The most important step in preparing your paving project is compacting the soil before you lay the pavers. If you do not compact the base soil foundation, ground movement will warp your paving over the following years creating humps and hollows.
What Is a Tamper Tool? Tampers are manually operated or power compaction tools. They increase the density and levelness of soil, gravel, sand and other materials by applying force to the material's surface. This force can be delivered by hand or via a gas-burning engine.
What are the different methods of compaction?
The method of compaction is primarily of four types such as kneading, static, dynamic or impact and vibratory compaction.
You can use a garden hose with a low-pressure spray nozzle, a sprinkler or lay perforated soaker hoses on the ground. Low-pressure and drip systems work best because high-pressure water moves soil on the surface and usually runs off the surface before it has time to drain into the soil.
Secondly wet it. Ensure the moisture content in the soil is correct. Moisture in your soil is vital to achieving proper compaction as the water helps slide soil particles together.
If the backfill under the slab has not been properly compacted, the structural fill will eventually settle, leaving voids. Since a slab-on-grade is not meant to be structural -- supporting its own weight plus any imposed loads -- the slab will certainly crack if the voids are large enough.
You can protect the joint sand from washing out by sealing the paver surface. Sealing restores the beauty of your pavers. The paver sealer also serves as glue between the joint sand particles hence holding them together, and preventing the sand from being washed away when it rains or during pressure washing.
When watering in the Poly Sand, remember Goldilocks - "This is just right." Don't use too much or too little water. The amount of water you use is a critical element to an installation. Using too much water can cause the joint to over-saturate and result in polymer washout, mushy sand, and a weak bond.
Polymeric Sand needs a minimum depth of 4 cm (1 ½”) to be effective. Use a power washer to empty the joints. If there is already polymeric sand between the pavers, soak the sand to soften it up before emptying the joints.
A minimum of 24 hours drying time is required prior to allowing significant foot traffic and 48 hours for vehicular traffic on the paver surface. Polymeric sands are designed to soften and re-heal.
Hand tampers are good tools to use if you want to manually compact your pavers. Although it takes a lot of effort to achieve a high level of compaction, some homeowners prefer to use it.

Can I use a tamper instead of a plate compactor?
Tamping rammers are better for clay soils and smaller areas. They compact the soil through impact. Plate compactors are best for gravel, sand or silt and larger areas and compact through vibration. Consider your soil type and size of the job when choosing a tamping rammer vs plate compacter.

Here's why: dirt shrinks by 30% when compacted. That means, if you backfill with dirt, your hardscape will settle 30%. This becomes an issue because, if you backfill with 10″ of dirt, your pavers will settle around 3″ over time. However, if you properly lay a gravel base, you'll essentially eliminate settling.
A wacker plate is used to create a level and compact sub base before laying further materials such as tarmac, paving or asphalt. Also known as compactor plates, they are comprised of a vibrating plate with a motor on top, and are fitted with important safety features.
"The soils easiest to compact are soils with spheric and smooth particles," he continues. "Soils with irregular particles are more difficult to compact but, on the other hand, they have a larger bearing capacity."
You will need to use a wacker plate or another type of compactor if you are constructing anything on an area of land, or laying a concrete slab on the ground. Professional contractors would never build a structure without properly compacting the ground to ensure a sturdy and solid surface.
The best equipment in compacting your pavers is plate compactor as it uses both vibration and weight pressure which means it causes less time but covers a wide area, other tool you can use to compact your pavers are rammers which takes more time and only uses vibrations.
Applying Sand
Pour the sand onto the pavers and sweep it into the joints. Using a broom handle or some other blunt object, tap on the pavers. This will cause the sand to consolidate. Sweep more sand into the joints until the sand is within 1/8” of the top of the paver.
Estimating the Paver Sand
Paver sand holds the pavers in place and allows you to adjust them. The final paver sand depth needs to be 1 inch and you need to account for sand filtering into the paver base and into the joints between the pavers. Make your calculations using a sand depth of 2 inches or 0.1667 feet.
The amount of sand you use can make or break your paver installation, so it's best that you use no more than the recommended 1 inch. Here's why: A sand layer that is too thick can create waves in your patio during the installation. Pressing pavers into a thick sand bed may result in misalignment and a messy look.
Do you need to compact pavers?
If you fail to compact, you'll experience sunken or raised pavers. In other words, a bumpy, uneven base will produce bumpy, uneven pavers. The best practice is to compact your gravel base, in both directions, with a steel tamper or a plate compactor 2″ at a time until you've achieved the right thickness.
Tamp the sand down after leveling, then measure the depth, add more sand when needed and tamp it again. Keep tamping and checking the level until you have a completely flat surface.
We recommend you use a mini loader with a bucket to move large amounts of crusher dust around your job site. If you have the option, use a levelling bar attachment to quickly and evenly spread the material around.

A 1-inch level sand layer helps pavers to settle in a little in the bedding so that they can be fixed in place. The plate brings the pavers down into the sand. The compactor moves causing the pavers to fall unevenly, as the machine runs over the surface when the sand layer is too thin — 2 inches, for example —.

STEP 6: TAMP THE AREA
The plate tamper will push the paving stone into the bedding sand while also vibrating the jointing material into the cracks. If you're installing paving stone with textured tops, a plate tamper with a protective mat underneath may be required. And that's paving stone installation in a nutshell.
The key to achieving a smooth, level surface for the pavers is preparing a solid base, followed by a layer of sand. To ensure that the sand is a consistent depth, lay two pieces of metal pipe in the space and screed the sand off level with the top of them.

Wet the material. Wetting the crusher dust not only reduces the amount of dust in the air but also allows for a firmer compaction rate. Once wet, use a vibrating plate to further compact the particles together (please note that depending on the area that needs compacting, larger machines could be used)
