Ed, agree totally. The slab was laid professionally and I have faith in what has been done. The slab is not angled from the center but is angled very slightly away from the side bays, this is so when the heavy rain falls here in Brisbane it does not well up a create issues. You will notice there are three bays in the drawing below and I do not want water build up in super heavy rain in what could be classed as the two large catchment areas. The POD will be sealed and touch wood no water will enter the enclosure
