Kiln dried sand, sometimes called Silica Sand, is sand that has been specially processed by drying it in a kiln to remove moisture. This process results in an incredibly thin and dry sand, making it ideal for specific applications like block paving.
Understanding Kiln Dried Sand
Kiln dried sand is distinguished from standard construction or playground sand primarily by its moisture content and grain size. The drying process, conducted in a kiln, ensures that virtually all moisture is removed. This results in a fine, free-flowing material. As mentioned, it is sometimes referred to as Silica Sand.
The description of it being "incredibly thin" indicates a very fine grain size. This fine texture, combined with its dryness, allows it to perform tasks that damp or coarser sands cannot.
Key Uses of Kiln Dried Sand
One of the most common and effective uses for kiln dried sand is in block paving. Its unique properties make it essential for both installation and long-term stability of paved surfaces.
- Filling Gaps: Due to its dry and fine nature, kiln dried sand is perfect for filling in gaps between paving blocks. It can be easily brushed into the narrow joints, providing a snug fit.
- Providing Structure: Beyond just filling joints, this sand is used to provide a firm structure for the blocked paving itself. It helps to lock the blocks together, creating a stable and durable surface capable of withstanding traffic and weight.
Its description as "easy to use sand" highlights that its dry, free-flowing nature simplifies the installation process, allowing it to settle well into the required areas.
Summary of Key Features
Here's a quick overview of the characteristics of kiln dried sand based on its description:
| Feature | Description |
|---|---|
| Alternative Name | Silica Sand |
| Processing | Dried in a kiln to remove moisture |
| Texture/Grain | Incredibly thin (fine) |
| Primary Use | Block Paving (joint filling, structural support) |
| Ease of Use | Easy to use (due to dryness and flow) |
In essence, kiln dried sand is a specialist sand product valued for its dryness, fine texture, and effectiveness in providing structure and filling joints in applications like block paving.
