At Advanced Mini Piling Systems, we can install Driven Piles in many restricted locations:
(Fume extracted and electric rigs are also available)
Steel Casing Dia (mm) | Max Safe Working Load (kN) | Minimum Hammer Weight for energy requirement (kg) |
65 | 20 | Top Driven |
85 | 30 | Top Driven |
100 | 10 | Grudomat Driven |
150 | 90 | 250 |
220 | 250 | 500 |
275 | 350 | 750 |
323 | 500 | 1000 |

The Grudomat is an air driven piling system, meaning it can be supplied with compressed air from a long distance with little disruption. Grundomat driven piles are an excellent solution to sites, where restricted access is a major factor in cost, this method requires no piling rig and is extremely mobile. Capable of installing piles for small extensions, orangeries, garden rooms, conservatories and porches. The Grudomat is placed inside the piling tube which has a point crimped on one end, and a collar on the other end. The Grudomat sits on a dry mix concrete plug and follower tubes are welded on until a pre-determined set is reached. No spoil is removed from this system and there is little vibration.
Driven Piles from 150mm – 323mm, are used in areas of poor ground conditions, where access is restricted and other piling systems are not economically viable. Our machines can pass through a standard doorway, and can be operated 50m away from the power pack. (Diesel/Electric powered motor which drives hydraulic pumps feeding the rig via umbilical hoses, that is mounted on a trailer). Steel Cased Bottom Driven Piles, are driven through the soft upper lying stratum, with extensions welded on until the pile has reached a predesigned load on friction, or the pile is driven onto a rock head. Driven piles once completed provide a clean bore which is water tight, and is then cast in situ by concreting from the top, or they can be grouted from the base of the pile, with design specific reinforcement installed, connecting piles to Ground beams.
Depths of piles depend on loadings and soil values provided by site investigation, which our engineering team will be able to arrange.
