River Pebbles for Paving
Characteristics of River Pebbles
River pebbles, thanks to their smooth, rounded shapes and variety of sizes, are ideal for various paving applications. The use of pebbles for flooring is relatively recent, with the first examples dating back to the 18th century. These pebbles are particularly appreciated for their durability and versatility, making them suitable for paving in historic centers, driveways, sidewalks, and private courtyards.
Colors of River Pebbles
The color of the pebbles varies depending on the stone from which they are derived:
- River pebbles: Typically mixed gray, white.
- Granite or marble pebbles: Vary from black to pink to red.
- Luserna stone: Presents a range of bright or dull shades, covering all the above-mentioned colors.
Sizes of River Pebbles
The size of paving pebbles varies according to the intended use:
- 2-4 cm pebbles: Suitable for light pedestrian pavements.
- 4-6 cm pebbles: Used for pavements with moderate pedestrian traffic.
- 6-8 cm pebbles: Suitable for pavements with light vehicular traffic.
- 8-10 cm pebbles: Ideal for pavements with heavy vehicular traffic.
Installation Methods for Pebble Paving
River pebbles are used in various types of exterior paving, primarily as a decorative element rather than the main walking surface due to their irregularity and relative discomfort. Here are the steps for laying paving pebbles:
Preparing the Bedding:
- Create a bed of sand and dry-mixed cement. This layer serves as a stable base for the pebbles.
Placing the Pebbles:
- Arrange the pebbles on the sand and cement mixture, trying to create an aesthetically pleasing and homogeneous pattern.
Moistening and Vibration:
- Moisten the pebbles and use a vibratory plate to ensure they are well fixed in the bedding. This process helps to stabilize the pebbles and reduce any voids.
Grouting
- Perform grouting with a mixture of sand and cement in the appropriate doses, filling the spaces between the pebbles to ensure their fixing and stability.
River pebbles represent a versatile and durable solution for exterior pavements, combining functionality and aesthetics. Their installation requires care and precision to ensure stability and a high-quality final result.
