Can you lay Artificial Grass on Slabs?
There are numerous reasons why you might want to lay artificial grass in your garden – it is extremely easy to maintain, will withstand several years of abuse from children and animals, doesn’t require water or fertiliser, and looks great too.
But if you want to keep some natural grass in your garden or only have the option of installing on top of concrete, you may be wondering whether it is even possible. Thankfully, you can lay artificial grass on slabs.
What you need to know about laying artificial grass on slabs
The process of laying artificial grass on slabs is much simpler and more straightforward than doing so in an area of your garden where there was once a lawn. This would have to involve removing the existing turf, adding a base layer of sand, levelling the surface, and finally adding a membrane layer,
But when laying artificial grass on slabs, you virtually have a clean canvas to work with from the get-go. In fact, the distinct advantage of slabs is that providing they are level, all you need to do is cut your artificial grass to size, roll it out, and stick it down.
What you need to remember when laying artificial grass on slabs
Despite the ease in which you can lay artificial grass on slabs, you will still need to bear a few things in mind:
- Ensure there are no large gaps (larger than half an inch) between your slabs – This can cause sagging over time, especially under footfall. The solution is to fill in any gaps with some quick drying cement.
- Lay artificial grass on a clean surface – Give your slabs a good sweep before hand, getting rid of any debris that could cause bumps underneath and prevent the grass from sticking.
- Leave drainage gaps around the perimeter – This only applies if you are gluing artificial grass to a concrete surface. Although artificial grass can slow down drainage significantly, concrete is less porous than earth. You may also want to apply a slight gradient to allow water to drain.
- Be aware of any trip hazards – If the installation of artificial grass partially covers a driveway, patio, or path, consider the fact it will add another 15-40mm above the surface area. Diminishing areas or a simple border can prevent accidents and injuries.
Follow these steps and you won’t encounter any major problems when laying artificial grass on top of concrete slabs.
