Grundomat Piles


Do you want to learn about an advanced and effective construction method used in ground stabilization? Grundomat Piles are an efficient technique developed to create a secure foundation for buildings.

This article will provide readers with an overview of the constraints, benefits, fields of application and technical specifications of this valuable asset. Unravel the secrets behind how flexible, durable and cost-effective Grundomat piling can be for your project needs – whatever they may be! So let’s get started!

The Grundomat Piling Method

The Grundomat method is a unique air-driven piling system used to drive piles into the ground with compressed air.

Construction sequence


  1. The ground is prepared by removing topsoil and any obstructions
  2. cylindrical Grundomat air-hammer tool, known as a dull tool, is inserted into the pre-drilled hole
  3. Compressed air is used to drive the pile deeper into the soil at predetermined depths depending on required load bearing capacity
  4. Each pile can range in size up to 200 mm in diameter and are driven until they reach refusal or stop sinking due to rock bedding or other suitable landscape features
  5. Mini piles from 0.8m up to 5m are typically grouped together either with interlocking beams of reinforced concrete members decorated with anchoring tie bars running horizontally or vertically between each mini piles using casted floor slab thicknesses reaching 400mm for typical structures
  6. Survey tubes are driven or installed pit prior entering construction works so surveyors can evaluate movement of excited land anchors during construction activities 7 Once piling works have been successfully completed then earth backfillings material may be applied around every single pile shafts ensuring stability


Fields of application

Grundomat piles are versatile and effective for a variety of civil engineering projects. The method is especially suited to constructing foundations, retaining walls, bridge abutments, slope stabilization structures and underground utilities.

Grundomat pilings have been used in large-scale construction endeavors such as the Poolbeg Incinerator project in Dublin Ireland where nearly 1,000 Grundomat piles were installed to form the base for the sprawling facility.

Similarly, it has also proved instrumental in smaller applications like telecommunications poles at Wodonga Australia which require more stability than conventional support systems can provide.

Technical specifications

The technical specifications of a Grundomat pile are critical to understanding its functionality, efficiency, and application. The following table outlines the key technical details of this piling system:


Driving MethodAir driven using compressed air supplied externally
Application AreasSuitable for regions with limited access and noise restrictions
Pile DiameterTypically around 150mm
Installation MethodSteel tubes driven by a vibrating hammer
Pile Surface AreaConcentrated largely in the shaft
UsageCommonly used for foundations and underpinning
Additional EquipmentSteel casings vibrated down to the strata using Grundomat system


These specifications make Grundomat piling an effective method for various construction applications, particularly where access is limited, noise must be minimised, and robust foundations are required.

Overview of Piling and its Importance

Welcome to the world of Grundomat piles! Grundomat is a popular and cost-effective piling system used in many construction projects, ranging from small domestic works like property extensions, to large scale commercial buildings.

In this blog post, we will discuss how Grundomat pile systems can be used for ground stabilization and provide an overview of its features, benefits, technical specifications and environmental impact.

We’ll also look at the advantages of using a bottom-driven piling technique over other popular methods. So let’s dive right in and learn more about how these innovative piles could revolutionize your next project!

Environmental Impact of Grundomat Piles

Grundomat piles are an advanced and environmentally friendly mini piling solution. This type of piling involves the use of a hollow stem auger to drive in pre-cast reinforced steel or concrete piles into the ground.

This tool is easily operated by one operator with minimal environmental impact, making it a popular choice for both residential applications and large scale projects alike. Compared to conventional steel pile installation, grundomat piling does not generate loud vibrations during pile driving, greatly reducing noise pollution levels.

Additionally, no soil needs to be removed during this process which further reduces any negative effects to the environment that using traditional steel piles can have.

The introduction of mini-piling including grundomat piling has also reduced the overall carbon footprint when compared to fully cast concrete or driven pile proceedings significantly due to utilising a smaller amount of raw material components such as steel and concrete while simultaneously ensuring quality performance through publically accredited tests regimes such as Petrotex testing requirements by certified professionals.

In terms of underpinning operations which require minimal disruption amidst existing buildings that could potentially interfere with foundations in future expansion stages like additional storeys onto existing structures there is limited space for manoeuvre thus demanding precision excavation works; Grundomat Piles provide nonintrusive effective solutions compared to conventional steel models whilst also potentially providing potential savings on time if lighter machinery types are used for execution purposes although regular inspections must still occur since screw brackets created during workmanship processes!


In conclusion, Grundomat piling is an air driven technique that uses compressed air to drive piles. It has advantages over other forms of pile driving in terms of cost-effectivenessversatility and minimal environmental impact.

Its technical specifications allow it to be applied across domestic and commercial projects alike and its lightweight portability makes it perfect for those with limited access or noise restrictions.

The availability of specialist machines has made this system increasingly popular in the UK market for both underpinning and extensions as well as small scale ground stabilization projects.
