Very simply put, we used the 2 inch geo ground grid for our yard design, the installation and result were exactly what we wanted.
We laid down weed fabric, and then expanded out the geo grid, anchored it down and filled it in.
I really wish we would have more to say, but it was that simple. Only thing I would highly suggest to customers is to take your time on the geo ground grid. Anchor it down tight and it will perform exactly the way that you want it to.
Thank you Standartpark - and the rumors about the customer service here are true, excellent customer service.
