How do I stop my pavers from sinking?
Compacting causes the stones to form a tight bond with the bedding layer, which reduces the chance of your pavers sinking again. Sweep joint sand into the joints between the pavers. Do this by pouring a pile of sand on your hardscape and sweep it over the stones until your joints can’t hold any more sand.
Can you lay pavers directly on dirt?
Typically, it is not recommended to directly lay down pavers over dirt. For pavers to look and perform well in a permanent installation setting, the ground/dirt floor must be excavated, leveled, and hard compacted.
How thick should sand be under pavers?
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.

Can I use sand as a sub-base?

If you are building a patio close to or attached to the house, use a hard rake and/or shovel to level the area and make sure it slopes away from any structures. The base material (most commonly the ground) should be tightly compacted using a hand tamper or plate compactor.
How far apart should pavers be?
The recommended space between the pavers is 3 mm (⅛”). I don’t expect you to measure the gap but just set them beside one another. You should stop every 4 feet and pull a string line along the laying face, with a screwdriver, adjust that face to the string line.
What if it rains on my paver base?
Rain can certainly be an interfering factor in the paver installation process, but not so much as to completely interrupt the execution. … It is best to postpone work until the rain stops and the material dries, but keep in mind that pavers can get hot, so a sweltering summer day may not be the best choice either.

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.

Can you use polymeric sand as a base?
The silica and other binding additives in polymeric sand reduce the amount of water that can wash between the pavers and down into the base materials. This keeps the base foundation under the surface sturdy and intact. It deters weeds. Weeds are amazingly resilient and can grow almost anywhere.
What is a paver pad?
Paver patio base panels are made from lightweight high-density polypropylene. The panels typically have tongue-and-groove or shiplap edges to keep the panel edges flush with one another. You may wonder how a thin plastic mat can effectively replace a 6-in. -deep layer of compacted gravel.
Do you need a pad on the plate compactor?
