Do You Need Drainage Under Artificial Grass?

Yes, drainage under artificial grass is essential. The grass surface is porous, allowing rainwater to pass through to the sub-base. However, the effectiveness of drainage largely depends on the sub-base installation. High-quality artificial grass should drain water through a specially designed drainage base beneath the levelling layer, typically sand.

Understanding Sub-Base and Drainage

What is a Sub-Base?

A sub-base is a layer that sits underneath your artificial grass. Its primary role is to provide a stable foundation and facilitate adequate drainage. The most common materials used under artificial grass for a sub-base are crushed stone or gravel, allowing water to filter through easily.

Don’t think about laying fake grass directly onto the soil; it won’t work.

Why is the Sub-Base Important for Drainage?

The sub-base plays a crucial role in preventing waterlogging. Without a well-installed sub-base, water can pool beneath the grass, leading to mould, mildew, and a shorter lifespan for your artificial grass.

Types of Drainage Systems

Perforated Drainage Layers

Some artificial grass installations include a perforated layer that helps guide water away from the surface, ensuring the lawn remains dry and usable, even after heavy rain.

Graded Foundations

In areas prone to heavy rainfall, graded foundations can be used. These are sloped subtly to encourage water to drain away from the grass area, preventing moisture accumulation.


What if My Garden is Prone to Waterlogging?

If your garden has a history of waterlogging, additional measures like a more robust drainage system or a thicker sub-base may be required to ensure proper drainage.

Can Drainage Affect the Look of My Grass?

Properly installed drainage will not affect the appearance of your artificial grass. It helps maintain its look by preventing water accumulation and the growth of moss or weeds.

Is Extra Drainage Expensive?

The cost can vary, but investing in good drainage is crucial for the longevity of your artificial grass. It prevents future problems and additional expenses related to maintenance and repairs.

Installation and Maintenance Tips
