Understanding Sandstone
Sandstone is a sedimentary rock composed of sand-sized mineral particles, primarily quartz and feldspar, bound together by natural cementing agents such as silica, calcite, or iron oxide.
This composition gives sandstone its characteristic durability and aesthetic appeal. One of the most significant advantages of sandstone is its versatility in design, as it comes in various colors, including shades of beige, tan, brown, and even red, allowing for seamless integration into different architectural styles and landscapes.

Installation Process
Installing a sandstone retaining wall requires careful planning, proper techniques, and skilled craftsmanship to ensure long-lasting results. Here’s an overview of the installation process:
1. Site Preparation:
Clear the area where the retaining wall will be installed, removing any vegetation, debris, or obstacles. Excavate the soil to the desired depth and compact the base to create a stable foundation.
2. Foundation:
Construct a sturdy foundation using crushed stone or gravel, ensuring proper drainage to prevent water buildup behind the retaining wall. Compact the foundation thoroughly to provide adequate support for the wall.
3. Placement of Sandstone Blocks:
Lay the sandstone blocks or bricks according to the chosen design, ensuring proper alignment and levelness. Use a combination of mortar and adhesive to secure the blocks in place, taking care to maintain consistent joint spacing.
4. Backfilling:
Backfill the space behind the retaining wall with gravel or drainage aggregate to promote proper drainage and prevent soil erosion. Compact the backfill material in layers to ensure stability and prevent settling over time.
5. Finishing Touches:
Once the retaining wall is in place, add finishing touches such as capstones or coping stones to provide a polished look and protect the top surface of the wall from weathering and damage.
