Wagstaff Piling has the most extensive range of retention pile techniques of any piling contractor in Australia, providing a range of innovative methods to design and construct the best retention solution for the site.
Wagstaff Piling owns one of the largest fleet of diaphragm wall equipment in Australia for constructing robust retention systems. The fleet is capable of installing walls 300mm to 1200mm thick in a variety of ground and site conditions.
Diaphragm walls are a safe and cost-effective solution for retaining the vertical faces of excavations. They are ideally suited to sites that are close to existing roads or buildings and can be used in conjunction with props and ground anchors. Constructed on a panel-by-panel basis formed in the ground, diaphragm walls restrict the effect of ground movement caused by excavation work.
Wagstaff Piling owns and operates a large fleet of equipment to complete secant piles to suit a variety of ground conditions.
Secant Pile walls are interlocking or overlapping cast-in-place bored piles forming a continuous near-watertight wall in unstable and water-bearing soils. This method prevents water or soils leaching between the piles after excavation.
This piling technique can be used to construct walls, tanks, basements, or similar type below-ground structures.
Wagstaff Piling constructs cut off walls using bentonite cement slurry and grab techniques for different applications. These include controlling seepage from wastewater retention structures and mine waste slurry basins or dams.
Sheet pile walls can be either of a permanent or temporary nature. A wide variety of materials, steel, plastic, or concrete, can be installed using percussion, hydraulic or vibratory hammers. Interlocking sheet pile walls are used for many applications including cofferdams, basement walls, pits, and marine structures.
Wagstaff Piling can design and install precast concrete sheet piles for appropriate site requirements. The sheet piles can be used for riverbank protection and retaining walls and can be manufactured to suit different structural configurations.
Wagstaff Piling can design and install temporary or permanent anchors for a variety of structural and foundation piling applications.
Wagstaff Piling can design and install economical Vibwalls to act as a continuously sealing cut-off element, in the ground, for excavations, dams and landfill applications.
