With pile driving rigs starting with our small 6 wheeled Toyota rig, perfect for driving 150mm SED house piles through to our 25T excavator mounted rig we can provide solutions for most driven timber or driven steel pile requirements.
For drilled piles from 200mm to 2.1m diameter and beyond we have a range of excavator pendulum auger equipment, 3.5T to 25T, with abilities to drill piles in not just easy clays but through rock or when casing is required. We have developed our equipment around the requirements of Wellingtons difficult sites often needing long reach and deep piles.
Capable of drilling any hole from 200mm to upwards of 2.1m diameter as deep as 14m, Darlington is the team to take on all your drilling requirements. Wet - soft ground through hard rock, we have the machinery and expertise to take on any site, steep tight access house additions to large commercial developments, transmission lines and cellphone towers. We don’t just drill the holes, we can also provide and install pile reinforcing cages, timber and steel piles, temporary or permanent casings, supply and place concrete and remove drill tailings from site. Our knowledgeable team are equipped to take on anything.
From small domestic additions with just a few piles, through driven piles for new builds and large commercial developments, Darlington Drilling and Piling provide and install driven timber piles, driven UC or UB steel piles and driven railway iron piles. Driven timber piles from 150mm small end diameter (SED) through to 350mm SED. 150mm SED timber piles are the most common piles driven for new houses. 175mm and 200mm SED can also be driven for houses. Driven UC or UB steel piles, galvanised when required, are driven in a range of sizes and lengths for projects such as footbridge foundations, commercial buildings and retaining walls. Driven railway iron piles are commonly used for rural roadside retaining walls. They are also a practical option for building foundations where piles are required to be driven through difficult ground conditions where timber poles could not be driven without damage. Rig sizes range from our compact 6-wheeled Toyota piling rig utilising a 500kg drop hammer through to our SK235 (25T) excavator mounted piling rig with an 870kg hammer. We have piling rigs of all sizes for different site requirements. We also use excavator mounted vibro-plate drivers, hydraulic breaker/driver systems and excavator mounted hydraulic vibratory hammers of varying sizes. We can also offer pre-drilling or pre-punching on difficult or sensitive sites.
