Prolapsed vent - am I getting it right?

[Kelly.b]

Have a new to me (2nd hand) mk1 cube with 3m run ready to go.

Have 10 x slabs so far but need advise/recommendations on setup. Have a choice of possible sites.

1. Mostly in shade against back wall, the area can get quite moist so will need to be prepared properly to remain dry.

2. Grassed area, partial shade still fairly sheltered.

so I guess you slab the complete area under run and use an artificial flooring. Then slab over the run edges to prevent fox digging.

Any advise greatly received.

cheers

I would go for 2, but you don’t slab “over” the run edges! You just make sure the slabs extend beyond the run so that the skirt rests on the slabs as well. 

Make sure you think about drainage too. If water can get in, it needs to go somewhere. So either angle slightly so it can run off or leave spaces between slabs.
