What are Screw Piles?
Our Screw Piling product is the cheapest, quickest and strongest screw foundation system in today’s market. Our robust and rigid single helix no longer restricts the structural integrity of a screw pile.
Screw piles transfer building loads via the shaft (typically CHS section, 76mm dia – 273mm dia) to the helix plate, which is located at the bottom of the shaft. Sizes and thicknesses of each member is engineer designed to allow for all design loads and geotechnical conditions as per your project.
​
Our product uses only one heavy duty thick helix plate. Our helical plates vary from 8mm up to 36mm in thickness. Our product is engineered, tested and accredited. We take confidence in our approach and proposals towards any engineer and ensure our design is backed up and warranted by the Australian standard and an Engineered Certificate.
Complying with the Australian Standard: AS 2159 – Section 8. Our screw pile product allows engineers, developers, builders, homeowners to build with full confidence.
What are Bored Piles?
Bored piles are commonly used as a foundation solution when the conditions of the ground are considered fair to good, i.e. there is; no threat of shallow water table, soils are cohesive or rock and spoil removal is not a problematic or costly trait (such as contaminated / asbestos or acid sulphates). Bored Piles drilled into rock conditions, enhance the chances of minimising any foundation settlement. We provide top-of-the-line bored piling services in Sydney and surrounding areas. We own various types of track-mounted drilling rigs and excavators which are capable and available to drill depths up to 30m into high-strength rock.
Bored Piles are drilled with circular augers, cleaned, and then filled with concrete and steel-reinforced cages. The Soil/Rock is removed using certain designed drilling tools, such as soil augers, rock drills, core barrels and clean-out buckets, which can reach a depth of up to 30m and range in diameter from 200mm OD to 1200mm OD. We have several methods available to support the walls/sides of the pile during its construction. This is assessed and selected according to the ground condition being drilled into i.e. soft soils, stiff clays or rock layers, the level of the groundwater found and the environmental constraints on site. In the case where a drilled hole requires intervention to remain open (before the soil/sand collapses the hole), we use a steel liner/casing which can be permanent or temporary.
