Hot Tub Help!

[Engineer54]

5/8 coupled 7 rods straight down by hand!
I know there will be limited contact here while the soil consolidates where the couplers have made the hole bigger
As for siting rods next to the building I know !
I lifted the slabs and tried different areas and managed an average of 16 inches , this one kept going , so did I lol

Although as I've said before there is a lot of rubble approx 2 - 3m and this one is now clear of that and presumably into clay ( house is on a riverbank)
Will having a rod further away be a problem?
I know it'll reduce the overall value but I'm thinking as the ground immediately around the tub is poor
I can definitely get some in on the side of the property which is around 14 metres away lovely soft ground!!

Are you saying you have 7 rods coupled together going down 8.4 metres?? If this is a riverside property, then you must of hit the water table at that sort of depth. I'm not sure if it's going to be a worthwhile exercise going for another position, if you only achieve 45 ohms going down 8.4 metres. Nothing to stop you trying mind, if money/costs is not going to be a problem. Maybe try excavating around the existing rod and treat with a generous amount of Bentonite....

Yes 7 coupled together plus 2 in a nearby position, it is a riverbank
but I reckon the rods point will be just about the same level as the river now as the house is on a steep bank roughly 7/8 metres higher than the river bank edge

It was quite frustrating as I always keep putting rods in until I can't do anymore and aim for a highest reading of 20 ohms but if I can put more in I do and usually get it a lot lower, this has been for Domestic or Agricultural
