Artificial grass underlay may not be necessary for all installations but in the right situation it can increase comfort and assist drainage, meaning your lawn will stay looking good for much longer.
What is underlay?
Underlay – this sometimes called a ‘shock pad’ layer that sits between the artificial grass and sub-base. Foam-like, rubberised or a specialist pad suitable for outdoor use. For Artificial Grass Cheltenham, contact https://luxury-lawns.com/artificial-grass/cheltenham/
What underlay actually does
A good underlay can:
Soften the ground underfoot (great for kids and pets)
Better shock absorbency for play areas
Aid in covering up small imperfections in the base, minimise bumpy feel
Adequate drainage if combined with proper sub-base
Protect the most frequent areas of use by cushioning
When it’s worth it
When to think about underlay:
For softer feel for children playing or pets
The place is heavily used (dog runs, walkways, common gardens)
You’re installing on a solid substrate (e.g. concrete or decking)
You are setting up a playroom and want more cushioning
When you may not need it
So, if your installer is doing the correct base work (usually a compacted sub-base with a smooth finishing layer), and this will be lawn that gets very light use, you might not need to consider underlay. Additionally, if the wrong underlay is added in some cases it may actually prevent proper drying out completely, blocking moisture from outdoor drainage.
The bottom line
Not every garden requires underlay, but when used in the appropriate location it is an upgrade that adds comfort and durability. So check with your installer what they suggest for your settings (surface, drainage and use of the space).
