STEP 1: HOLES
DETERMINE BOUNDARY LINE, POSTHOLE CENTRES & DEPTHS
Please read the wind region and post hole depth charts carefully prior to starting your installation.
We recommend you plan your wall set out/post position on a piece of paper first to save unnecessary digging.
Where installation is to take place on uneven or sloped ground, you should also consider the instructions listed
under “Additional Information” towards the end of this guide.
Accurately determine the boundary line to where the fence will be installed and mark this with a string line as per
the diagram below. In cases where the boundary line is unknown or unclear, a surveyor will need to be engaged.
NOTE: The diagram below is for reference purposes only & shows the wall splitting the boundary line; this may
not always be the case and will depend on your individual circumstances.
Standard post centre-to-centre measurement when using a 2400mm panel will be 2420mm minimum (Plus
5mm extra is an allowable tolerance i.e 2425mm ). This will give you the required clearance when installing the
wall panels.
NOTE: Wall panels may be trimmed with a circular saw if necessary to fit within an exact measurement
(panel cutting procedure is detailed on page 24 of this guide). Postholes can be dug by hand or with a
mechanical auger. Use the Footing Depth Table to determine your posthole depth and diameter.
NOTE: Recommended footing depths listed here are for terrain categories 2.5 and 3, within wind regions
A and B. If you are building your wall in a Cyclonic wind area, on the top of a hill, adjacent to an
escarpment, on a ridge, or in terrain category 1, you will need engineering advice beyond the scope of
this publication. Please contact ModularWalls directly for this information.
