Hi everyone I have a omlet walk in run at mo it's in the garage because where having building work done so the door is open all day and there out loads .. I'm worried that when its out in the garden the wind will blow it away,, I have a cover over the top which would catch the wind it's going on a patio when done before it was stacked down ,, am really worried how can we secure it more to the ground ??? Any ideas
