Looking at home with 1.5 in gap between poured basement wall and basement slab. The house was built in 1996 and I am not sure what this is.

Asked by rtbs921, Alpharetta, GA Mon Dec 17, 2012

Is this normal for a home in GA in Alpharetta area? (new to state) Are french drains or floating basement slabs normal here? Also, there is no sump pump.

That gap is highly unusual for any home anywhere, and could be related to many things, but of course without seeing it, not mush else can be said. French drains are common (after the fact) installations in metro Atlanta, floating slabs are not - this gap does not sound like it is related to either.

You said "looking at the home" are you looking on your own, or are you represented by a buyers agent?

If not, I can help you see suitable properties and am also qualified to tell you exactly what condition any home is in, and to advise you when there are problems you should run from.

Let me think about the last time I saw proper compaction of the subsoil before concrete was placed....and let me think about the last time I saw proper placement of rebar and wire....and the last time I saw concrete slumped to ensure proper mositure content...or the last time concrete was allowed to cure 28 days before being backfilled or built upon. Still thinking....

Might be a floating slab, but might be movement. French drains are used as needed, foundation drains are common, sump pumps infrequent and rare with slabs. I would recommend a home inspection - GA has heavy clay soils and poor drainage, moisure is a constant concern and proper construction, surface water control and regular monitoring is critical. If this is a stucco home that's something else to think about -

What is your agent saying?

In most cases basement slabs are not structural. There is a footing below the foundation wall that is the actual load bearing surface of the walls. I've seen some buildings with a gap like this that were designed to let any moisture that came through the wall run down and below the slab. All cases I've seen though, have had subsoil drainage and sump systems. I wouldn't consider this a deal breaker, but I'd definitely have an inspector take a close look at it if you are considering it. As nobody can accurately analyse it without seeing it. Good luck.

Are you just curious or are you seriously considering a purchase of this property?

No one here can help you.

This requires on site, hired advisory help, doesn't it?

That is not unusual, but I would strongly recommend you hiring a home inspector before buying any home. Among other things, a good home inspector can walk you through the house and explain what is normal in building practices here and what you should be concerned about. Building practices vary around the country and since this is such a large purchase you need to protect yourself.

If you need a recommendation, please call or e-mail me and I'd be happy to help you out.

Without seeing it, rtbs921, would be difficult to ascertain the situation, but I doubt a gap that size was designed. Especially if you don't have a similar gap on the opposite and possibly, the adjoining walls. If this is absolutely the deep deal of the day for you, consider hiring a good inspector or engineer to analyze the structure. Please call, text or email if we can provide further assistance. Good Luck!
