Why Proper Installation Matters
A high-quality artificial grass product can last many years, but poor installation can lead to uneven surfaces, drainage problems, visible joins, wrinkles, and premature wear.
Correct installation helps:

- Create a smooth professional finish
- Extend the lifespan of the grass
- Improve comfort underfoot
- Reduce maintenance requirements
Whether you choose 20mm, 30mm, or 40mm artificial grass, the foundation underneath is just as important as the grass itself.

Preparing the Ground for Artificial Grass

For most UK gardens, a depth of around 75mm to 100mm is excavated before adding a compacted sub-base. Proper preparation prevents sinking, uneven patches, and drainage issues later.
