Mini Piles & Screw Piles

There are many ways to underpin a building’s foundations – and piling is considered one of the most versatile options. The London Underpinning team can advise on which piles are appropriate for the job.

How to Select the Right Piles

At London Underpinning we use both mini-piles and screw piles.

Mini-piles are often an economical solution where ground conditions are particularly poor. We use mini-piles to allow us to use needle and pin underpinning techniques, as well as for piled raft constructions or mini pile and ground beam new-build construction.

We have recently started using screw piles which can have advantages over other piling methods. They are clean, easy to use, easy to handle, they don’t displace much soil and there is no concrete used. We recently completed a project in Primrose Hill, London where screw piles were specified for environmental reasons.

Mass Concrete Underpinning

A traditional form of underpinning in which box cavities are dug below the original foundations and they are filled with concrete to strengthen them.

Beam And Base Underpinning

Reinforced concrete beams are placed on a concrete bases which provide support, under the existing foundation. The building load is then shifted to the bases.

Mini Pile Underpinning

Mini piling is used in restricted spaces, where structural movements are minimal. Mini piles have hollow steel shafts capable of withstanding heavy weights.

The Difference Between the Two Piles

Both screw piles and mini piles are used in underpinning; their differences lie in the design and the way in which they are installed.
