We have a townhouse complex that is on the second floor. The building is a "U" shape. There is a central courtyard in the middle of the U that has some private use space for each homeowner, which we need to fence off for each unit. The courtyard base is a concrete slab that has a waterproof membrane on it, which is then topped with 4.5" of rigid styrofoam insulation and then some compacted gravel and a combination of 2' x 2' pavers (for walkways) and artificial turf.
We are looking for a solution that would give us a reasonably solid fence without drilling any brackets into the concrete slab (and thereby penetrating the waterproof membrane). We've been told to avoid doing that at all costs. Whatever base we use could sit ON the membrane/slab, but is not physically attached to it. At the building perimeter, the fence can be attached to brick walls, so it's the posts that hold the panels extending out from the building that need a good mounting solution. This is kinda like a floating fence. Anyone have any creative solutions to this?
