Choosing the Right Sandstone for Your Retaining Wall: Factors to Consider

Sandstone retaining walls serve as functional structures and add a touch of natural beauty to any landscape. Several factors must be considered when choosing the right sandstone for your retaining wall. From the type of sandstone to its colour, texture, and size, each element plays a crucial role in determining your retaining wall’s overall aesthetics and durability.

In this blog, we will explore the key factors to consider when selecting sandstone for your retaining wall, helping you make an informed decision that enhances your landscape’s form and function.

1. Type of Sandstone

The first step in choosing the right sandstone for your retaining wall is to consider the type of sandstone available. There are various types, including quarried sandstone blocks and natural stone retaining boulders. Quarried sandstone blocks offer a uniform appearance and are ideal for a contemporary or formal design. On the other hand, natural sandstone boulders provide a more rustic and organic look, perfect for a more natural and textured retaining wall. Understanding the different types will help you align your choice with your landscape’s desired aesthetic and style.

2. Colour and Texture

Sandstone is available in various colours, from warm earthy tones to vibrant reds and yellows. Consider the existing colour scheme of your landscape and choose a sandstone colour that complements it. Additionally, pay attention to the texture of the sandstone. Some sandstones have a smooth and refined surface, while others exhibit natural variations and ruggedness. The choice of colour and texture will significantly influence the overall visual impact of your retaining wall.

3. Size and Shape

The size and shape of the stone retaining blocks or stone retaining boulders play a vital role in the stability and appearance of your retaining wall. Larger sandstone blocks provide a more substantial and structured look, while smaller blocks or boulders create a more intricate and textured design. Consider the height and length of your retaining wall and choose sandstone pieces that are appropriate for the scale of the project. It’s also important to ensure that the selected sandstone blocks or boulders are uniform in size and shape to facilitate ease of installation.

4. Durability and Strength

When building a retaining wall, durability and strength are essential. Sandstone with high compressive strength and low water absorption is preferable for retaining wall construction. Ensure the sandstone you choose can withstand the soil’s pressure and stabilise the structure. Consulting with a professional or experienced sandstone supplier can help you select the most suitable sandstone with the necessary strength and durability.


Can sandstone retaining walls withstand soil erosion?

Yes, sandstone retaining walls are highly effective in preventing soil erosion. The interlocking nature of the sandstone blocks or boulders, combined with proper installation techniques, creates a stable barrier that holds back the soil. Sandstone’s natural strength and durability make it an excellent choice for retaining walls, even in areas prone to erosion.

How do I maintain sandstone retaining walls?

Maintaining stone retaining walls is relatively simple. Regularly remove debris and organic matter from the surface of the wall. Avoid using harsh chemicals or abrasive cleaning agents that may damage the sandstone. If moss or algae growth occurs, a mild solution of water and gentle detergent can be used for cleaning. Additionally, inspect the wall periodically for any signs of damage or structural issues.

Can I install a stone retaining wall myself?

While installing a sandstone retaining wall yourself is possible, seeking professional assistance is recommended. Proper installation techniques are crucial for the stability and longevity of the wall. A professional can provide expertise in excavation, foundation preparation, and the adequate placement of stone retaining blocks or boulders. This ensures the retaining wall is structurally sound and meets the necessary engineering requirements.

Is sandstone an environmentally friendly choice for stone retaining walls?

Yes, sandstone is considered an environmentally friendly choice for retaining walls. It is a natural and sustainable material that is sourced from quarries. Sandstone has a low carbon footprint compared to synthetic materials. Additionally, sandstone retains its natural beauty over time and requires minimal maintenance, reducing the need for regular replacements.
