Help! Oak pillar

[foxhole]

Muck fillet would speed the rot .

lead is placed in slot cut 100mm up from base around post and run out over entire base slab . No water can enter .

With respect but that is not a good idea. Cutting a slot exposes end grain in the slot.

In 1980 we DIY built a Walter Segal timber frame ( post and beam ) house. The design is that the posts ( Douglas Fir and Oregon Pine ) stand on lead sheet on the paving slab. 38 years later ( and 4 floods ) the posts show no signs of deterioration due to water.

The photo was taken before the excess lead was trimmed.

Cannot see end grain - this it sits on a 2mm bead of sealant which sits on the stone. That sealants isn’t stopping the water ingress.

Not sure if the muck would really seal - would there be a gap between wood and muck as the wood expands etc

Was thinking marine mastic muck or lead mate to keep fox happy , needs to be dry though , is a summer job probably be gone by then , back to silver . Or hairdryer needs be dry or wont seal .
I can see the lip and transition to end grain from here ?
Could use Oxalic acid to kill the mildew and clean it off if you really need something to be done .

I like the idea of the slot - what would I use? Lead? Won’t look great? And what sealant would I use?

Slot cut upwards at 45degrees , silicon and push lead up into it , will need skill so not really diy, job for pro.

I've seen these or might have done one they have been allowed

to sit on a stainless steel leg about an inch or two off the slab this just looks like a feature this obviously stops the moister rising up the end grain from the slab

Hi darrenh
Did you resolve this issue, which option did you use, was it successful?
We are just encountering same with a new porch oak pillars standing IN brick pillars. Now considering adding a LEAD COLLAR to prevent water getting down between oak pillar and into the brick it is standing in.
