How Thick Should Sand Be Under Pavers?

Paving roads and patios use sand instead of a sticky mortar mixture. Underneath the pavers is a compact sand bed which provides a coiled base. The pavers will soon become rough and misaligned when you use more than the usual 1 inch of sand. In order to lock the pavers efficiently in place, bedding sand must consist of multi components of sand like concrete sand. 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 —. There will be waves in the resulting road or patio.

​

Together with an uneven surface with holes and peaks, a deep sand layer helps seal the paver. The flat compactor vibrates into the dense sand of the pavers. Excess sand fills the joints slowly and spills over the edges on the paver. This causes the pavers to lock and float haphazardly at the surface of the sand .. Even when the edge of the perimeter is restrained, sand gradually erodes out of the joints and causes spreading and a misalignment of pavers.

​

After you have laid your pavers, you fill the joints with sand to create a flat and continuous surface. With a thick sand foundation, the pavers do not create a unified surface, rendering the joints uneven. The compactor can not efficiently vibrate the sand as you fill the joints with sand. The particles are not well preserved in your joints and the sand is diminishing steadily. As a consequence, the Pavers chip each other without the coiling of the sand joint.

​

A 1-inch sandbed is created using a 1-inch electrical duct diameter or a PVC tube. Before spreading a single sand in your subsurface, place two tubes in the excavated area in parallel. When you stretch the material in the excavated area use the height of the tubes as a measure of the sand depth. Since the tubes obstruct blocking the paver, cut the tubes and fill the sand room when the pavers are set up.
