Applications

Commercial and Industrial

 Screwpiles instantly generate compression and or tension load resistance and allow builders a greater degree of construction sequence flexibility. Construction sites that present  challenges such as difficult ground conditions, high water tables, limited accessability can be managed with relative ease.  Some examples are:

• Where a building has a basement foundation system and the site boundaries have adjoining buildings with its foundation system terminating at  higher levels than that of the proposed new basement.  The water table is also above the new basements underside of foundations.  The boundaries that require shoring or retention may be microfine grout injected, sheetpiled or contiguous piled with excavation being carried out after the shoring and de-watering is installed.  Where basements are subjected to hydrostatic loads (from the tanking or bath effect) once dewatering is turned off, the basement foundation system needs to be anchored to the ground.  The sub-foundation system (piling) also needs to transfer significant compressive loads deep below basement level as a weak soil layer exists below basement level.

This scenario is a classic example of where screwpiles should be used as load serviceability is available immediately after screwpile installation allowing for concrete piles caps to be constructed without the need for costly concrete pile curing delays.

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

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

• 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 disruption to the immediate areas normal day to day operations. The project engineers is conscious of the need to ensure no damage to adjoining site is caused by any piling vibration and noise must be kept down to a minimum.  The piling works is going to need to be deep (up to 30m) and time constraints are critical.  Site access is limited and the area to work in is confined.

The use of pendulam based excavator machinery for screwpiling installation delivers greater onsite maneuverability over conventional piling methods.
