When it comes to creating a lush and healthy lawn, selecting the right materials is crucial. One common question that arises during the preparation process is whether turf underlay and topsoil are the same thing. While they both play important roles in lawn establishment, there are distinct differences between the two. In this blog post, we'll explore the dissimilarities between turf underlay and topsoil, and shed light on their individual purposes.
Turf underlay and topsoil serve distinct functions when it comes to creating a thriving lawn. Turf underlay refers to a specific type of soil blend designed to promote healthy root development and aid in water drainage. It is typically a mixture of sand, organic matter, and soil conditioners, ensuring optimal moisture retention while preventing waterlogging.
On the other hand, topsoil refers to the uppermost layer of soil, rich in organic matter and nutrients. It provides a fertile base for plants to grow and offers a natural habitat for beneficial microorganisms. Topsoil contributes to overall soil health and aids in the establishment of a robust turf.
In conclusion, while both
turf underlay and topsoil are vital components of lawn establishment, they serve different purposes. Turf underlay aids in root development and drainage, while topsoil provides the necessary nutrients and organic matter for overall soil health. For all your landscaping supplies needs, including

Yes, turf underlay is essential for the successful establishment of a healthy lawn. It provides a well-draining medium for the roots, allowing them to grow deeply and firmly anchor the turf. Turf underlay also helps maintain proper moisture levels, preventing overwatering or water logging issues.
Typically, a turf underlay soil layer of around 50-100mm (2-4 inches) is recommended. This thickness ensures adequate depth for root growth while still maintaining a suitable balance between drainage and moisture retention.
The ideal soil blend for turf underlay should consist of a balanced mix of sandy soil, organic matter, and soil conditioners. This combination promotes proper drainage, moisture retention, and nutrient availability, creating an optimal environment for healthy turf growth.
Yes, it is important to lightly compact the topsoil before laying turf. This process helps create a level and stable surface for the turf, ensuring good root-to-soil contact and minimising air pockets that could hinder root development.
The height of turf underlay will depend on various factors such as the existing soil condition and desired turf thickness. Generally, a turf underlay layer of 25-50mm (1-2 inches) is recommended to provide a suitable base for the turf to establish and thrive.
