Mini Piling

Mini Piling, also known as Micro piling, are often used for underpinning. They are also used to create foundations for a variety of project types, including highway, bridge and transmission tower projects. They are especially useful at sites with difficult or restricted access, or with environmental sensitivity.

Offering a range of smart geotechnical and ground engineering solutions, Aarsleff Ground Engineering UK are trusted mini piling contractors who offer numerous structural solutions, including Precast Concrete Piles, Steel Bearing Piles, Timber Piles, Mini Piles, and Sheet Piling.

Why choose Aarsleff Ground Engineering as your mini piling contractor in the UK?

Aarsleff Ground Engineering can work on a wide range of schemes- whether it’s multi-use residential developments, hospital and health care buildings, schools and universities, wind turbines, commercial units that need a variety of pile types, or infrastructure like rail, embankments and roads.

Whether you’re concerned about site constraints or poor soil at a shallow depth, or have large design loads, our experts can offer both temporary and permanent solutions. One of our foundation solutions include a fast, sustainable, zero-waste precast ground beam system for house foundation packages, alongside all other geotechnical techniques ranging from drilling and grouting, soil nails and ground anchors to king post walls, sheet piles and driven piling

Why choose mini piling? 

The size of the mini pile is determined by the load-bearing capacity of the ground and the size of rig that is able to access the piling location.

They can be driven or screw piles and tend to be used where access is restricted, for example underpinning structures affected by settlement. They were first used in Italy in the 1950’s in response to the demand for innovative underpinning techniques that could be used for historic buildings and monuments.

They are particularly suited to:

  • Shallow bedrock.
  • Boulders and cavities.
  • Immediate hard strata.
  • Where underpinning is required, such as for foundations adjacent to planned excavations.
  • Micropiles can also be used in combination with other ground modification techniques where complex site conditions and design specifications are present.

In a typical installation process a high-strength steel casing is drilled down to the design depth. A reinforcing bar is inserted and high-strength cement grout pumped into the casing. The casing may extend along the full length of the pile, or it may only extend along part of the length of the pile, with the reinforcing bar extending along the full length
