Where discolouration (darkened appearance or fungi) on the soil is apparent as compared to other soil appearance in the sub-floor area. Where the minimum outside ground level is 200mm lower than the inside bottom edge of the floor joist. Where there is no sub-floor access, coupled with the solar option or external power point (or internal power point mounted on the inside skin of a perimeter wall) total installation can be completed from the outside.
