Many road signs are installed by simply sticking a pole into the ground. This type of installation is highly susceptible to ground movement because the only thing that holds it in place is friction. If the ground moves due to excessive rain or frost heave, the sign will be affected. This can cause the signs 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 signpost in stable ground. This method ensures that the installation remains unaffected by either rain or frost. The outside sleeve of the helical pile connects securely to the sign's post. Even if the ground above is affected by water and frost, the sign 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 helical pile’s stability, ensuring that it doesn’t move, even though the upper surface of the ground does.
Advantages of Postech Screw Piles
Postech Screw Piles are also fast and simple to install, requiring only one trained operator and one piece of equipment. This makes them an extremely cost-effective alternative to other methods of road sign 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.
One of the significant advantages of using Postech Screw Piles is the minimal disruption to existing landscaping. Unlike traditional methods that may require follow-up landscaping crews, the site can be left alone to recover naturally. The only disruption will be the actual hole for the helical pile’s blade.
