Is sand beneath the brick walkway favorable?

brick walkway

One uses a different kind of materials and methods to construct a walkway, but brick pavers often look for versatility and durability. Wet ingredients need not be incorporated for brick paths, unlike the cement sidewalks. Since sand is used beneath the brick to give long-term stability, one need not worry about the pavers changing over time.

Benefits of using sand

Many of them prefer not to use sand under the brick walkway at their own cost. If pebbles and sand are not mixed with the soil, it could cause the brick to sink and move over a period of time. Shifting or sinking of the bricks creates an uneven surface later leading to a tripping problem. Sand placed underneath the bricks embraces it and firmly secures its position. The sand surrounding the bricks will allow it to shift a bit while installing in order to make it an even walking surface. Sand prevents washout during heavy rain. Brick walkways can be easily repaired or replaced because it does not harden the bricks when placed on the sand. Using the sand allows a certain amount of rainwater to enter the ground. Setting bricks in sand is less expensive and cleaner when compared to working with mortar.

Need for a trench

Before laying the sand and brick pathway, one needs to dig a trench. About 8 inches in depth can accommodate about 4 inches of gravel bases, 2 inches of sand and 2ΒΌ inch thick bricks. Once the trench is dug, a garden rake can be used to evenly distribute the soil evenly on the remaining gravel.

Installing gravel

Coarse gravel should be used as a base for the walkway. The edges of the coarse gravel are usually flat that helps it to rest against one another and sticks into place to prevent shifting after the installation. Once the sand is evenly distributed, a garden hose is used to wet the gravel and allow the sand to settle. Once installed, the gravel is flattened out using a hand tamper.

Application of sand

Sand can be directly emptied from the bag into the trench filled with gravel. As the sand fills, it enters between the gravel and fills the cracks. The sand covers the gravel to make an even depth of approximately 2 inches. The bricks are then placed into the sand. A rubber mallet is used to tap each brick into place.

Therefore, sand should be used while installing brick walkways.
