Retaining wall trouble?

    Nothing major I hope? I have a kinda weird situation. Around the foundation of my house is a slab of concrete. It looks like a walk way that sourrounds the intire house. Not sure why this was done and what the purpose is?

    My plan is to take retaining wall bricks and build an area in which I had wanted to put shrubs, or flowers. The bricks are on the edge of the concrete slab and I would like to fill the space between the bricks and the foundation with soil. But I thought of one problem, no drainage. The wall is roughly 5 high, the height of the foundation.

    Can this be done without problems?? My concerns are drainage and root growth. Hope I explained my self.

    No, just a crawlspace.

    How far out does this slap go?

    It sounds like your describing the footing of your foundation, but a footing should be on the bottom of a 2'-4' stem wall, so you shouldn't be seeing it :)

    How thick is the slab?

    If you are positive that this slab is purely ornamental and not your footing, then you could cut it along the stem wall and rip it out, or punch drain holes in it every 12" or so.

    The slab extends roughly 18-20" out. The depth is 3-4". I've seen this done on many houses before, but never understood the purpose. The slab doesnt go completely under the house,just surrounding the foundation. It looks like a walkway.

    Yeah, that was one thought. But what about depth problems. I want to put shrubs and Im not sure how well they would hold up in soil that's fairly shallow with a slab underneith. Root growth is my other concern.

    That would worry me ... I hate laying anything over concrete.

    If you can't tear it out defiantly punch holes in it. What else can you do?

    edit ...there must be some purpose to that slab ....someone here should know... I wouldnt do much until I found out that.
