Applications

Commercial / Industrial

A screwpile's ability to quickly generate high load capacities in both tension and compression allows building designers a high degree of design flexibility. It gives builders the ability to streamline multiple trades onsite simultaneously. Sites that present  construction challenges such as poor or difficult ground conditions, high water tables, hydrostatic uplift loads on basements, limited accessability etc can be managed with relative simplicity. Examples showing advantages are:

• Where a building has a basement foundation system and site boundaries have adjoining buildings with foundations terminating at  higher levels and the water table is above the basement RL .  Excavation only being done after shoring is constructed. Where the basement is subjected to hydrostatic loads from the tanking bath effect, with the basement foundation system subjected to uplift forces when dewatering is turned off. The basement's foundation system will need to be securely anchored to the ground and the foundation system needs to transfer significant compressive loads deep below basement level as a weak soil layer is present below the excavation level.

This is an optimum situation for screwpiling, as screwpiles provide instant tension and compression load capacities. Installation is by water tables and interface connection to pile caps can be done instantly.

• A group of buildings constructed on a site with organic or loose layers present at a depth >1.5m.  Excavation and disposal is expensive and  boundary excavation  is not possible due to existing structures on boundaries, water is also present.  The developer wants to utilise as much building area space as possible  and  even if the loose material is excavated, it cannot be continued up to the boundary  as a soil batter of  original material must remain, requiring that part of the building to be piled.

Installation of compression screwpiles simply transfers all the building's design loads to below the problem area with no need for soil excavations. 

• A number of deep, high capacity dual compression tension piles need to be installed on a confined sensitive commercial site.  Piling works need to happen quickly and without obstruction to the site's normal day to day operations. The project engineers engaged Screwpile Australia to provide a solution where 10 x 10m deep x 400kN SWL bolt spliced (site welding was not permitted) piles and pile extensions which were installed in one day using a single 325 CAT excavator installing machine.

The fact that screwpiling is conducted using excavtor based machinery provides great installation flexibility over conventional piling methods. From multi-storey buildings to conveyor towers and complex buildings on restricted sites, Screwpile Australia and its associated companies in the Screwpile Technologies Group will go the extra mile to deliver the best outcome for its clients, regardless of how complex the foundation problem.
