Building sand, often called builders sand, isn't "made" in the traditional sense, but rather it is obtained through specific processes involving natural sources. The key is that the sand needs to have specific properties to be suitable for construction purposes like creating mortar, concrete or screed.
Sources of Building Sand
Building sand is primarily sourced in three ways, as detailed below:
| Source | Description | Key Feature |
|---|---|---|
| Quarrying | Extracting sand from land-based deposits where it has accumulated over time. | This process is like mining but at a shallower depth. |
| Sea Dredging | Siphoning sand from the seabed. | This can be a contentious practice due to the environmental impact. |
| River Mining | Extracting sand from riverbeds. | Water sources provide sand with preferable properties for building purposes. |
Why Water Sources?
The reference highlights the importance of water sources for obtaining building sand. This is because:
- Water naturally helps to create sand particles that are better suited for mixing with other materials, such as cement or aggregates.
- The sand grains from these locations tend to be the right shape and size for the purpose.
Preparation for Construction
- Once extracted, the sand usually needs to be screened and washed to remove any impurities and to ensure the correct grading.
Why Is Builders Sand Important?
- Builders sand is a fundamental component in the construction industry.
- It is used for mortar, which binds bricks and blocks.
- It is also a crucial ingredient in concrete and screed.
In conclusion, building sand is not manufactured but is sourced from nature through quarrying, dredging, or mining, primarily from water sources. These methods ensure that the sand is suitable for use in various construction applications.
