Looking to build about a 100 meter fence wall, maybe 2 meters high. Just along one side of a property.
Yeah the entropy of the tropics is a bitch!
We've built about 400 meters of fence. Right after we first moved here our neighbor rented out an adjoining plot. The tenant thought it was ok to graze his Carabao on the organic rice we had in the field.
Our first iteration was large bamboo poles and barb-wire. The poles lasted about a year. At the end of the lifespan we would go down the fence line and re-sink the poles.
But that was an awful lot of hot, hard damn labor that must be done every year. That sedimentary maintenance requirement builds up real fast.
Few years later we replaced the Bamboo with cast concrete fence posts. We also replaced the bottom three strands of B.W. with cyclone wire. That lasted 2 years before the cyclone rusted out and gave up the ghost. A lot of the posts broke. Seems they were cast from the same weak a__ mix that local hollow blocks are.
Hate to disagree with you Rufus ..... but around my barangay ..... hollow block has about a 5 year lifespan before it goes mouldy and weak.
Our back perimeter fence is good. Severely over grown but still strong. It is cast concrete columns about 12" on a side with 9 strands of B.W.. 8 horizontal. The ninth zig-zags vertically and ties the other 8 into place.
The oldest fencing I've seen, is around the Tarlac orchards. It is cast in place concrete posts with cast cement panels running horizontal.
I don't have a good solution to fencing. And it's something that I gotta solve.
