How to install paving stones

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.

Sand Bedding

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.

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.

A 20×20 brick paver patio costs $3,800 to $6,800. The average cost of pavers and base materials is $4 to $6 per square foot, while labor runs $6 to $11 per square foot.

Not compacting the base

Before laying bedding sand or pavers, your gravel base needs to be flat and firm, without any bellies or rises of more than 1/8″. You accomplish this kind of precision by properly compacting your base and your pavers. If you fail to compact, you’ll experience sunken or raised pavers.

The Interlocking Concrete Pavement Institute recommends washed concrete sand as the best base sand for pavers. Concrete sand, also known as bedding sand, is coarse and doesn’t trap excess moisture beneath the paver surface.

Can I Use Regular Sand Between Pavers. Yes, normal sand serves this purpose very well. Fill gaps between pavers and help lock the individual blocks in place, so they don’t shift. If possible, use irregular, sharp-grained sand, as they have sharp edges and bind together better.

There is no absolute rule to determine how required depth, however recommendations vary by use. The guidelines are 4 to 6 inches for pedestrian walkways and 8 to 12 inches for driveways. Local soil conditions also impact depth needs.
