What do you put under paver base?

Before laying the pavers, a layer of bedding sand is placed over the compacted base material. This layer provides a bed into which the pavers are set. The sand bedding also helps to protect the sand joints from being eroded away.

Is paver base better than gravel?

The only significant difference between gravel and paver base, is that the sharper edges of paver base mean it can lock together more effectively than gravel when packed down under the sand and pavers. However, this does not negate the use of gravel if you tamp it down well enough.

How thick should sand be under pavers?

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 —.

Should I use paver base or sand?

A GRAVEL BASE LAYER BEFORE SAND IS A MUST! Using sand alone to set pavers is not enough. The best and recommended paver base is 3/8-inch crushed gravel. The gravel provides a flexible base that absorbs ground tension to prevent frost heaves.

How thick should gravel be under pavers?

The traditional base for a paver patio is 4–6” of compacted gravel above your dirt.

How much will pavers sink when compacted?

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.

Can I use gravel for paver base?

Medium gravel is the most popular choice for a paver base. It compacts well but not as tightly as fine gravel, leaving enough room for water to drain through. Medium gravel is the middle ground in terms of support and drainage, making it ideal for regular or loamy soil with an adequate amount of drainage.

However, generally what you should do is round the volume you calculated up to the nearest multiplier. For example, if you only have bags of 0.5 cubic feet available, and you need 47.7 cubic feet of some material, divide 47.7 by 0.5 and round up. The division would give you 95.4, meaning you need 96 bags.

Can you use paver base alone?

Paver base is a crushed gravel mixture used to provide a solid foundation for interlocking pavers. But, it can also be used as a stand-alone outdoor surface when packed tightly.

Can you put 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.
