Concrete vs. Postcrete
Hi all,
If I want to set a new wooden post into the ground, what's the difference (FFS)? |

Postcrete sets in a few minutes, several tens of seconds, even, so you don't have to support the post for nearly as long as you do with concrete. Don't know if the long-term durability is different though, or even if it matters, as it's only a post not a high-rise building, and the post will probably rot long before what it's set in crumbles. Wow! Cheers, Chris. I'd had nightmares already about holding that damn post perfectly upright for hours on end; cheers. |

Postcrete is also easier to use because you ram it in dry, and then pour water onto it, rather than having to mix it wet. -- Cheers, Roger ____________ Please reply to Newsgroup.

The post will usually start rotting where the soil touches it in the soil/air boundary. -- mailto: news {at} admac {dot] myzen {dot} co {dot} uk |

Postcrete is also easier to use because you ram it in dry, and then pour water onto it, rather than having to mix it wet. What's being overlooked is Postcrete *is* concrete in convenient ready mixed dry form. The magic of it holding the post quickly is down to it being ram-packed in slightly damp rather than wet. If bags are convenient or you only need a couple of posts worth, Postcrete makes sense. if you have a lot to do, mixing by hand might be better - just don't add water (if the sand is wet) or just add a little to help it clump. |

Yes, even before they've been sold by the retailer, I've noticed! Don't understand why they're not made from galavanized or stainless steel. But there are 4" ones available; less common but definitely available. I've seen various ingenious contraptions people have come up with on Youtube for removing posts, but am resigned to just drilling and digging the damn thing out the hard way with a 600mm long auger and a "texas toothpick" - anything more complicated seems an investment in wasted time followed by doing it the hard way anyway. There ought to be a good few quid in it for anyone who can come up with a compact, reliable and cost- effective method; I don't think one's been devised yet. |

Yes its been my experience that wooden posts in concrete tend to root sooner
than thouse just put into the ground. I guess the hole fills with water and rots it. Brian -- From the Sofa of Brian Gaff Reply address is active "Chris Hogg" wrote in message ...

Also only take 3x3 posts which are too weak for use anywhere with significant wind. Other than that, just fine. 4"x4" ones are also available. Galvanised and powder coated. I additionally put some waxoyl in the socket. To keep them straight whilst hammering in, you need to make a hole with a bar in the ground first (like a pilot hole) going down full depth of spike. Wobble factor depends on the depth of the sockets. |

Jonathan A weak concrete mix that's easy to remove when the post rots is the logical answer if you have loads to do, like on a farm etc. I dug a 5" x 5" hardwood gate post out of concrete the other day for a neighbour. The bits of wood below ground are still surprisingly un-rotten and a bitch to get out. |

So tedious that I left quite a bit in there, put some 6" screws into the base and re-set the thing in concrete. Also put a bracket on the adjoining wall the keep it stable till it goes off. Terrible bodge but apparently it's only temp till they have the wall rebuilt |

My mother has concrete posts supporting a chain-link fence across the bottom of her garden. Put in in the mid-1950's. The posts are falling to bits due to spalling. 8X And there's so much salt in the air in West Cornwall, driven off the sea by winter gales, that those steel Metposts only last a few years. So concrete ones only last 50 years by the seaside? That's long enough for me - and presumably ours would do better well inland. Andy |

wrap a builders plastic bag around the bottom of the post before you pour the postcrete in, the post will not rot then
