We are a screw pile manufacturer that provides businesses around the world with high-quality products coupled with excellent customer service. The patented screw piles allow optimum load capacity using the full design benefit of the particular size of steel pile shaft. So, what is a helical pile? The purpose of a helical pile is to provide foundational support for structures of all types and sizes. A helical screw pile is rotated into the ground by using a hydraulic drive head, powered by an excavator. Decks, Galleries. Helix Anchor Installation and Helical Pier Installation The plates give the foundation both tension and compression bearing capacity which enables them to be used for a wide range of applications across many industries and sectors. • A helical anchor/pile consists of one or more helix-shaped bearing plates attached to a central shaft, which is installed by rotating or "torqueing" into the ground. PDF, DWG, DXF formats for typical piles. However, for more robust deep foundation systems, concrete (also known as grout) can be incorporated. We do recommend soil surveys to be carried out so we can ascertain pile depth or size of helix however this system of piling can be monitored during installation so a good knowledge of the area and average soil type maybe suitable. The Paalupiste Helix series is a low cost but high-quality range of screw piles for consumer use. Forget about concrete! What is a Helical Pile? In a grouted column, concrete is continuously poured down the sides of the column, following the displacement plate and encasing the steel shaft. A Master of Science Project . Screw piles are wound into the ground, much like a wood screw. It is important to have a qualitative assessment of the soils being penetrated at various depths. Helical Piles are steel shafts with a series of low-pitched circular steel helical plates welded at strategic positions along the shaft. Affordable, material S355/420, helix thickness 4 mm, Made in Finland, guarantee 50 years. When engineered correctly, a deep foundation anchored with the correct helical pile design will last for many years. This is required for a few reasons. The helical pile, also incorrectly referred to as a screw pile, consists of a central hollow shaft of various diameters and sectional thickness, with helical plates strategically welded at given spacing. Recommended CAA Habitation A screw pile is a galvanized pole with a flat pile head at the top and a helical “plate” at the bottom. What are the benefits of our machine?

Nova Helical Piles LTD is a Certified Installer for the GoliathTech Screw Pile System. Screw Piles. The brackets are jacked up to mobilise the building load. Unlike the single plate helix traditionally used by the Australian screw pile industry, the multi-fin cast steel helix no longer limits the structural capacity of the screw pile. So what is a helical pile? Using an extension pile requires an extension adapter. Just like old-fashioned pile-foundations, helical piles (also referred to as screw piles, helical piers, helical anchors, etc.) THEY CAN BE LOADED IMMEDIATELY AFTER INSTALLATION. Helical piles are installed by twisting them into the soil, just like a corkscrew is twisted into a bottle of wine. What happens below ground, at the foundational level, might be more of a mystery to some. Smarter Structural Engineering. Once you understand what they do, what they’re made of and how they work, you’ll gain a whole new appreciation for these invisible, deep-foundation champions. A little bit about screw piers, which are steel poles with a steel helix on the bottom, that are screwed into the ground instead of bored piers. 3. Because screw piles are screwed into place using the integral helix system, no auguring is required, leaving no cleanup. This small disc pushes soil out of the way as it’s being screwed, leaving room for concrete to follow.*. Below are some basic facts about helical piles.
