MARKING OUT YOUR POST HOLES
Determine and mark any legal boundaries and/or
underground services.
Dig post holes using hand tools and/or a powered auger. See Tables A & B for required post-hole dimensions
and depths

e.g.
Measure out each fence-line and mark the post
positions.
Determine post centres as follows:
If the fenceline length does not work out as
multiples of the standard panel length - adjust
the length of the last section, or the last few
sections, to suit and cut panels to fit.
Use a string line or laser-level to make sure
any straight lines are aligned.
Standard ‘post centre to post centre’ guide
The table above allows you to work out what your post centres will be. If you have 1780mm slat [allowing
for 10mm either side of the channel] and you are using 65x65mm posts, then you will have an 1865mm post
centre to post centre This also shows the in-between measurements, should you be fitting your slat
between posts other than a 65x65mm profile, i.e, timber posts or concrete blocks

Recommended footing depths listed in this table are for wind regions A & B, plus terrain categories 2.0, 2.5 & 3.
If you are building your fence in a cyclonic wind area, on top of a hill, adjacent to an escarpent, on a ridge or in terrain
category 1, you will need engineering advice beyond the scope of this publication

Notes:
For higher walls, you will need engineering advice beyond the scope of this
publication
The diameter of your holes should be large enough to have a minimum of
75mm clearance around the post
Please note that 1800mm is the standard height. Heights lower than
1800mm can be done using these components, with wastage.
