If the
support posts on your property are warped, it means there were errors during
their installation: a preliminary soil survey was not conducted, construction
regulations were violated, or a foundation was chosen that was inappropriate
for the site conditions. If immediate measures are not taken to reinforce them,
the fence will fall onto nearby structures or people passing by.
In this
article, we will look at three methods for securely securing fence posts.
Concreting
Concreting
support posts or installing a strip foundation is used for heavy structures.
The foundation depth is determined based on the frost depth of the soil. To
reduce the buoyancy forces acting on the foundation, a well-compacted sand bed
is prepared. To protect the concrete foundation from moisture, waterproof it
using roll or coating materials.
Installation by rubble setting
For
lightweight, visible fences made of chain-link fencing or 3D Gitter mesh,
support posts are installed using rubble setting. To do this, specialists drill
a hole and create a sand bed. Backfilling with gravel is performed in stages.
Every 10-15 cm, the vertical level is checked, the gravel is watered, and
compacted.
Posts
installed using the rubble method are resistant to soil buoyancy and do not
require annual leveling. Remember, installing posts without sand or gravel
backfill does not guarantee a stable fence, even on non-heaving soil.
Installation on Screw Pile Foundations
A screw pile
foundation for a fence is installed on highly heaving soils. This foundation is
suitable for building tall fences made of corrugated sheet metal. The pile is
driven below the frost line. This prevents the posts from shifting as the upper
soil layers move.
For quick
installation and reinforcement of a fence, combined posts are used. The
two-part structure, consisting of a screw pile and a main post, is tightly
connected. This allows for fencing a large area in just one day. When choosing
piles, pay special attention to the steel grade and whether they have
anti-corrosion treatment. Low-quality steel quickly deforms under the weight of
the fence and loses its load-bearing capacity. The lack of a protective coating
on metal elements leads to rapid oxidation and deterioration.
Our
company's products are made of high-carbon ST-20 steel. We use powder coating
to protect the metal from corrosion. The polymer coating does not peel or wear
off when screwed in. Screw piles of all standard sizes are always available on
our website.
Entryway
The
entryway is an integral part of the fence and must also be properly installed
or reinforced.
To ensure
the gate opens smoothly at any time of year, the screw piles are tied together
with a metal channel. This eliminates obstruction to passage through the gate
and prevents the posts from shifting relative to each other.
Heavy swing
and sliding gates are installed on screw piles or a strip foundation. When
installing sliding gates, our team uses four screw piles:
• Three for
the support frame, which must be secured with a metal channel.
• One for
the receiving frame.
Using a
screw pile foundation, we create a level surface for the stable operation of
automatic gates over 5 meters wide. If you need to install a fence, gate, or
wicket door, please contact our specialists for a cost estimate.
The main
cause of fence collapses is improper installation of the support posts. To
prevent the fence from falling, the posts must be securely anchored. The
foundation must be suitable for the terrain, type, and weight of the structure.
