For smaller sites with limited access, or sites that are environmentally sensitive, the mini piling rig is ideal on a wide range of projects for example house extensions, conservatory bases, or detached building plots. Mini augered piles are installed in diameters of 150mm, 200mm, 300mm. Steel cased bottom driven mini displacement piles are 75mm, 100mm, 150mm, 168mm, 193mm, 220mm, 273mm, 323mm. All of our mini piling methods are available with full anti-heave precautions.
On large open sites with unstable ground the Continuous Flight Auger piles are the best solution for piling works as the auger stays in the pile bore to the final depth. As the CFA is withdrawn, concrete is slowly injected through the hollow stem of the auger into the pile. CFA is the quietest form of for forming piles suitable for noise sensitive sites. CFA pile are installed in diameters of 300mm, 350mm, 400mm, 450mm, 500mm, and 600mm. All of our mini piling methods are available with full anti-heave precautions.
On a site with restricted access, a piling rig may be unsuitable. A steel screw piling is an effective solution to this. They can be installed with a two man crew by hand or with the use of a mini excavator, making it an economic piling solution. Install up to 25 screw piles per day, reducing labour costs significantly compared to conventional piling methods. Screw piles work both in tension and compression making them ideal for underpinning work where they are used in conjunction with underpinning support brackets. Reduces muck away cost as screw piling produces almost no spoil. Available in a range of lengths and sizes with working loads in excess of 400-500kN.
Sites with restricted access, in areas that virtually no other piles can attain, a Grundomat driven piles create a highly effective piling solution. Piles operated by a Grundomat pile driving hammer are the most versatile piling solutions for restricted access locations like railway embankments, or on a much smaller scale for example conservatories. Grundomat driven piles are designed to use a minimal amount vibration, which essential when piling has to be carried out in noise sensitive locations. Most effective for home extensions and conservatories in residential areas. Diameters available100 mm/150 mm/165 mm. Minimum vibration. SWL of up to 130 kN.
or basements and ground stabilisation, or when the ground where there is an adjoining property must be maintained, a partial underground retaining all is required, contiguous piled retaining walls is the best method. The piles are installed approximately 50mm -100mm apart, subject to ground conditions, and are connected together by a reinforced concrete ground beam on top.
