An artificial lawn gives you a tremendous amount of possibilities when it comes to finishing it off with decorative touches, but you need to be careful that they don’t ruin your chances of keeping your lawn free of water.
Don’t forget that you also need to leave a clear route for any surface water to run off from your lawn when it rains. If you block the water run-off, then you will undermine everything else that you have done up to now.
While this water will soak through, it will take longer to do this, as you will be forcing more onto the lawn than is really necessary. This is exactly the same problem that you will suffer from a natural grass lawn or an artificial one, so if it is already an issue, then maybe you can do something about it while making the switch to artificial grass.
By doing this, you will give the water nowhere to go and force it to stay on the lawn. This problem is most commonly seen when people use the likes of timber edging but make it higher than the finished grass line.
