Sand filled pier??
Is there any real benefit from filling a steel pier with sand?
Have any of you done it and had noticeable positive results?
If so should the sand be dry or wet?
The reason I'm asking instead of just doing it my pier goes through the floor of my observatory about 400mm and bolts onto its concrete footing. If I fill it with sand I will no longer be able to lift it out if ever I need to make changes to it. (Even if I drilled a drain hole in the bottom and fitted a removable plug I don't think the sand would run out)
