Types of Natural Gravel Stone

Natural gravel stone is a small rock fragment that is often used in construction works. It is a naturally occurring material that is composed of rock fragments and is usually found in or on the earth's surface. Natural gravel stones can be used as decorative stones, in foundations, for walkways, and driveways, among other uses.

These gravel stones come in different types and sizes, as elaborated here below. They mainly differ in color, texture, and size.

• Bank gravel: This type of gravel is found near banks of rivers and streams. It consists of sand, stones, and gravel that have been deposited by water. It is used for concrete work, walkways, and drainage.
• Crushed gravel: This type of gravel is formed by the natural crushing of rocks. It consists of angular stones and rocks of different sizes. It is mainly used for road construction and pathways.
• Crushed stone gravel: This type of gravel is created by mining and blasting stone and rocks. The resulting stone is then crushed into smaller sizes through hammers and jaw devices. It is used for drainage and concrete.
• Creek gravel: This type of gravel is created through a natural process of erosion and is found in creeks. It consists of smooth, rounded stones and pebbles of different sizes. It is used for landscaping and decorative purposes.
• Granite gravel: This type of gravel is formed from the natural erosion of granite boulders. It consists of hard, durable stones that have been broken down into smaller sizes. It is used for driveways and decorative purposes.
• Marble gravel: This type of gravel is formed from broken-down marble stones and rocks. It consists of smooth, shiny stones that are durable and hard. It is used for decorative purposes and landscaping.
• Washing gravel: This type of gravel is created from the natural washing and erosion of rocks. It consists of clean, loose stones that are not compacted together. It is used for drainage and concrete.
• Sea gravel: This type of gravel is found in the ocean and consists of smooth stones and pebbles that have been worn down by waves and currents. It is used for landscaping and decorative purposes.
• Caliche gravel: This type of gravel is formed from a calcium carbonate material that hardens when wet and is found in arid and semi-arid regions. It is used for driveways and roads in those areas.

Functions and Features of Natural Gravel Stone

Natural gravel stone is used for a wide variety of purposes. Below are some of its features and functions.

• Construction

  Natural gravel is used in construction projects. It's an important component of concrete and cement. It is also used for backfill, creating roads and pathways in residential areas as well as highways.

• Drainage

• Landfill cover

  Gravel stone is used to cover landfills. This is because of its ability to provide a stable surface and control water.

• Agriculture

  It is also useful in agriculture as a water source. Excess water in farms can lead to flooding and destruction of crops. Farmers use gravel stone to create irrigation systems and drainage systems to control water and minimize flooding. It is also used to create firm pathways and roads in farms.

• Features of Natural gravel stone

  Natural gravel stone has different features that make it ideal for use in construction and other industries. Some of them include;

  Availability- Natural gravel is readily available, which makes it a cost-effective option for construction projects.

  Durability- This material is durable and stable, making it ideal for use in construction projects that require a stable foundation.

  Permeability- Natural gravel allows water to pass through easily without impeeding movement. This water drainage capability makes it a popular choice for creating walkways and road pathways in urban areas and farms.

  Versatility- This material is versatile and can be used in different ways, from constructing highways to creating drainage systems in farms.

  Low maintenance- Natural gravel requires little to no maintenance, making it a popular choice for creating road pathways and drainage systems.

Applications of Natural Gravel Stone

Natural gravel stone has many applications across several industries. This includes construction, automotive, and landscaping industries. Here are some of its common application scenarios.

• Construction

  Gravel stone is a key component in construction projects. This includes residential, commercial, and infrastructure projects. It is used in:

  • Foundations — Natural gravel provides stability and support for building structures. It is used in foundation beds and drainage systems.
  • Concrete — It is a common aggregate in concrete used for driveways, walkways, and building floors.
  • Land leveling — Coarse gravel is used to level land in preparation for construction.
  • Backfill — It offers support and prevents settling in utility trenches and foundation walls.
  • Landscaping — It is used to create decorative features like rock gardens, dry riverbeds, and pathways.
  • Drainage — Due to its permeability, gravel is used to control water in specific areas to prevent flooding and erosion.

• Road construction

  Gravel is widely used in building and maintaining roads, parking lots, and driveways. Crushed gravel is used as a base material for these applications, offering a stable foundation and a cost-effective surface.

• Automotive

  Gravel is used in the automotive industry to manufacture brake pads and shoes. Its high friction coefficient makes it a suitable material for brakes. Additionally, it is used for testing tire traction on different surfaces.

• Railroad ballast

  Natural gravel stone is used as railroad ballast. Its angular shape, high load-bearing capacity, and drainage properties make it suitable for this application. It provides a stable foundation for railway sleepers and tracks while allowing water to drain off quickly, preventing track damage.

• Landscaping and gardening

  Gravel stone is used decoratively in gardens and landscaped areas. It comes in different colors and textures, which improve the visual appeal of an area. It is also used to make paths and driveways that improve accessibility in a landscape.

• Sports

  Gravel is used in several sports applications. For instance, it is used to make beach volleyball courts, which have the right texture for players. Additionally, it is used to make running tracks in schools, especially those made of pea gravel.

How to choose natural gravel stone

Wholesale buyers should consider how each gravel type meets their customers' construction needs. Here are some factors to consider when choosing wholesale natural gravels for sale:

• Gravel's Purpose

  Each type of gravel has a different purpose. Check which type of gravel is best for the customer's intended use.

For example, river stones and pea gravel are less durable than crushed stone and granite gravel. However, the former are more visually appealing and thus preferred for landscaping.

• Gravel's Drainage Capabilities

  Most natural gravels have excellent drainage capabilities. However, some types like limestone tend to produce a high level of runoff. Therefore, consider the drainage characteristics of each type of gravel. Also, choose the one that meets the customer's needs and the intended landscape design.

• Gravel's Maintenance Requirements

  Various types of natural gravels have different maintenance requirements. For example, limestone gravel needs regular maintenance to avoid its deterioration. On the other hand, granite gravel requires little maintenance since it's highly durable and stable. Therefore, consider the maintenance requirements of each type of gravel to ensure it complements the customer's budget and needs.

A: Limestone gravel ranks as one of the most popular due to versatility across many uses. It works well for driveways, paths, and as a base material. Its ability to compact makes it an economical choice for projects. Other popular gravels are granite and basalt limestone, depending on location and availability.

Q: What are the four types of gravel?

A: Gravel is generally categorized into four types - natural gravel stone, crushed gravel, base gravel, and landscape gravel. Each type has different applications depending on whether it's naturally occurring or mechanically crushed.

Q: What are the two main types of gravel?

A: Gravel is categorized into two main types: crushed gravel and natural gravel stone. Natural gravel is made of sand, silt, and rounded stones and is found in riverbeds. Crushed gravel is produced by mining and crushing larger rocks, creating angular, sharp-edged pieces.
