The installation of screw piles is ideally a one-step process where pre-fabricated screw piles are secured into the ground. Since screw piles naturally displace soil as their shaft penetrates into the ground, you don’t have to pay for the soil to be removed from the site. This can be beneficial if the ground is contaminated. With screw piles, there’s no hammering or thumping, as they use the screw action to penetrate the ground. One of the major advantages with screw piles is that they can be installed on sites with little width or headroom, where machines used for driven or bored poles can go. The more versatile equipment ensures that the screw piles can be successfully installed around other plants or structures, which essentially makes retrofitting of piles feasible.
A screw pile is generally used where the soil profile is not strong enough to support a building. The installation method of a screw pile is quite simple. With the use of an excavator with a hydraulic drive motor attached, the screw pile is screwed into the soil, through any poor soil, until it finds a strong profile capable of supporting the structure. Once the screw pile is installed, a cut off height is determined by using the information from the architectural plans that has the pile working with the concrete slab or attached to a bearer, depending on the build method, to give the building a very solid base that will be guaranteed to last.
Screwpiling UK have 2 different options in the case of extremely restricted access piling – we have two handheld excavators at 400H and 700H respectively, ready to be deployed at any site.
