Ive seen some artifial grass today at quality save and looks lovley and thick ,my lawn is no more as the two dogs have ruined it ,it cost £30 per strip so because o only have small patch would cost me about 200 ,my worry is although they say it is pegged in down the sides ,would the slipping and sliding of my dogs dislodge it in the centre or would it stay put ,or would i have to prg it down the seams as well
If you're laying artificial grass, you should invest in buying the widest available strips possible. If you've found some 'bargain' artificial grass which isn't available in at least 2.5m width, it probably isn't a bargain at all.
Laid properly your dogs shouldn't disturb it. You need to clear and level the ground, put sturdy edging down to retain the area and dress the whole area with about an inch and a half of sand before compressing it and laying the grass.
Have you thought about how you'll clean the dogshit off the grass? I should think you'll need to hose down the area quite frequently, this might affect the sand base of your lawn.
