Precast Concrete Piling
Precast Concrete Piles are versatile and suited to most ground conditions. They are reinforced concrete sections which are manufactured off site in discrete standard lengths which are connected by designed joints to achieve the required length. They are moulded in various sections but are generally supplied in square sections up to around 400mm. Precast concrete piles are cast and cured in a casting yard and then transported to site for driving by a rig mounted hammer.
This is a displacement technique which results in little or no spoil arisings requiring disposal. Speed of installation is rapid and the piles are not affected by the presence of groundwater. Piles are driven to the required design length and any excess can be cut off with purpose designed cutters allowing follow on trades to commence.
We supply piles in 200mm, 250mm and 275mm square sizes in sections from 3m to 9m in length to suit the design loading requirements. Piles are generally spigot jointed but full moment joints are available.
Steel Tube Piling
We supply top driven heavy walled piles between 140mm and 244mm in diameter in sections from 3m to 12.5m long. The sections are API grade steel and recycle material from the oil and gas industry. Due to their slim cross section and low displacement steel tube piles can be driven in noise and vibration sensitive situations where other pile types would not be suitable.
Driven in lengths up to 14m, the high strength of the steel section provides the advantage of being suited to aggressive and complex ground conditions containing natural stone obstructions, sloping rock head or contamination. The piles are continuously driven using a threaded coupler joint where required and any off cuts are used on subsequent piles minimising wastage. Trimming of the piles is generally undertaken by flame cutting eliminating the risk of hand arm vibration.
Driven steel tubular piling is a displacement technique resulting in no arisings that would require disposal. This, and the resistance to chemical attack of the material, makes them ideal for use in contaminated ground conditions. Once trimmed the piles are immediately available for follow on trades.
