Tracey Concrete post and rail fencing are manufactured
to I.S. 252 1982 using a drycast system which
produces a dense durable concrete.
Although the most common is the three rail fence (Fig 1) as
shown in drawing, two rail fencing can also be manufactured to order.

The fence should be constructed to give a visually
pleasing flowing alignment with no abrupt changes in vertical profile.
Posts should be placed at 2505mm centres with double
post at corners, acute angles or where specified.
See Fig 2.
The holes for posts are normally bored with a 300mm diameter auger, 600mm deep.

20N concrete, min. 450 deep should be placed around
post except for end, corner or strainer posts where hole
should be filled to top.
It is advisable to make a jig for the accurate spacing of
post as they are erected and the top rail may be placed
in position at this time also.
Galv. Line Wire may be fed through the holes in posts were
necessary or specified. Proper straining ratchets should be used to tension wire.
As there is no strut to prop straining post, avoid
over straining specially on top wire which would
put unnecessary pressure on post. It is advisable
in this case to grout the slots around the rails in
the first panel of fence which will distribute the stress to the second post also.
