Screw Piles for road signs
While road signs are not the most structurally challenging installations around, they do need to be anchored firmly, especially against ground heaving caused by freezing. For this reason, Postech Screw Piles are an excellent choice for the installation of roadside signs.
Many road signs are installed by simply sticking a pole into the ground. This sort of installation is highly susceptible to ground movement because the only thing that is holding it in place, is friction. If the ground moves due to excessive rain or frost heave, the panel will be affected. This can cause the panels to tip over or even come off the ground completely.
How the installation works
Postech screw piles are unique in this approach because the screw blade is inserted below the frost line, anchoring the panel in the ground that will not move. Either due to rain or frost. The outside sleeve of the screw pile connects to the sign’s post. Even if it crosses the ground affected by water and frost, it remains stable, due to the solid base of the screw blade and Postech’s thermal insulation. The weight of the ground above the screw blade adds to the screw pile’s stability, ensuring that it doesn’t move, even though the upper surface of the ground does.
Postech Screw Piles are also fast and simple to install. Requiring only one trained operator and one piece of equipment for installation. That makes them an extremely cost-effective alternative to other methods of road signs installation. As the Postech Screw Piles are being installed, the equipment monitors the resistance encountered underground, ensuring that it reaches a point in optimal soil and below the frost line.
A huge advantage using Postech Screw Piles is, that they create minimal disruption to the existing landscaping. Instead of having to follow the sign installation crew with a landscaping crew, the site can be left alone to recover naturally. The only disruption will be the actual hole of the screw pile’s blade.
