I would suggest you go with LINQ

FilteredElementCollector coll = new FilteredElementCollector(doc, doc.ActiveView.Id).OfClass(typeof(FloorType)).OfCategory(BuiltInCategory.OST_StructuralFoundation);
var collFoundationSlab = from FloorType ft in coll where ft.IsFoundationSlab == true select ft;
foreach (Element myfil in collFoundationSlab)
{

}

Padhu,

The Class for Foundation slabs is CeilingandFloor and not FloorType. I had a similar issue trying to collect the foundation slabs and lead me to that. Hope this helps!
