What is Mini Piling?
Mini piling is the term used across the industry for small-scale piling carried out using compact, lightweight rigs — typically under 20 tonnes. It’s not a formally defined category: it refers as much to the equipment and access requirements as it does to pile diameter itself. Mini piles are conventionally considered to be under 300mm in diameter, though at Dawson Foundation Engineering we install piles from 100mm to 600mm using the same compact rig approach, since larger-diameter piles installed with lightweight equipment are still generally classed as mini piling in practice.
Mini piling is most commonly used where access is restricted, headroom is limited, ground vibration needs to be minimised, or work is being carried out close to existing structures — house extensions, underpinning, internal works and sites unsuitable for larger conventional rigs are all typical applications.
Pile Size
Mini piles are typically considered to be those with a diameter of less than 300mm. This can include various types of piles, such as bored, driven, drilled, or screw piles. At Dawson Foundation Engineering, we install piles ranging from 100mm to 600mm in diameter. While piles exceeding 300mm typically fall outside the conventional definition of mini piling, they may still be classified as such depending on the equipment used, as outlined below.
Piling Equipment
Mini piling may also refer to the use of compact or lightweight piling rigs, generally weighing less than 20 tonnes. These rigs are suitable for a broad range of applications, from installations in tight-access or low-headroom environments (e.g. through standard doorways), to medium-scale sites requiring greater power and depth capacity.
It’s worth noting that larger-diameter piles, even up to 450mm or more, may still fall under the mini piling category if installed using smaller rigs. The classification is often more about access, logistics, and rig size than strictly pile diameter.
Our Capability
At Dawson Foundation Engineering, the majority of our projects fall under the mini piling category due to the size and versatility of our in-house fleet. While our rigs are under 20 tonnes in weight, they are capable of installing pile diameters up to 600mm, providing a powerful combination of mobility and performance. This makes us ideally suited to tackle complex or constrained sites without compromising on structural integrity.
Applications of Mini Piling
We have a range of mini piling options available, providing solutions suited for:
- Residential and small-scale commercial projects
- Underpinning and foundation reinforcement
- Retaining walls (contiguous or king post)
- Internal works like mezzanine floors
- Sites with weak soils, dense granular soils, or contaminated ground
- Projects near watercourses or tree protection zones

Reinforced Concrete and Underpinning
In addition to piling, we undertake all types of reinforced concrete works such as ground beams, floor slabs and pile caps. We can also provide costs for setting out, excavation works, piling attendances and spoil removal.
We design and install a range of underpinning systems including traditional underpinning, cantilever beams, knuckle piles and internal piled rafts.

Specialist Equipment for Every Site Condition
We operate a diverse fleet of piling rigs and tools, enabling us to install piles efficiently across a wide range of site conditions, including restricted access and low-headroom environments.
- Grundomat Pile Driver: Our most compact installation tool, the Grundomat can be manually carried by two operatives, making it ideal for extremely tight or remote access locations.
- Kitten Rigs: Compact and versatile, these rigs are capable of operating within existing structures, including residential properties.
- GP Services D500 Drop Hammer Rigs: Featuring a detachable power pack, these rigs can be split from their engine units, allowing greater flexibility when navigating through narrow or enclosed access points.
- KLEMM 709 Rigs: Designed for performance in constrained environments, the KLEMM 709 enables the installation of deep piles quickly and efficiently, even on sites with limited headroom.
- Hütte 204 Rigs: These robust rigs are capable of installing large-diameter piles on sites where space is limited but headroom is not a constraint, making them ideal for challenging urban or industrial locations.
Our fleet allows us to provide the right solution for your project’s specific requirements.
