Origins of Contiguous Piling London

Piles have been used throughout the ages to stabilise foundations.

Thousands of years ago, contiguous piling was used to reinforce weak bearing ground, on weak peat soils near rivers to stabilise homes. Timber piles were used to reinforce the ground so that structures could be built for shelter. The piles were either manually forced into the ground, or fixed into holes by stones and sand filling the hole.  There are various sites in the UK where it can be seen where Romans used timber piles when making bridges. 

Another example of where this technique was used in the past is the presence of monasteries in East Anglia, which had piles of oak and alder used in the foundations to stabilise the structure, by contiguous piling.

Piling is a technique that has been used throughout the ages and is still used today by piling contractors London based.

Traditionally contiguous piling London methods involved using timber which combines strength and lightness, when used in sheet piling London techniques the timber was an excellent material for durability, strength and for cutting and handling.  Over time, the timber used in sheet piling London constructions have been replaced with steel and concrete. These newer materials are able to withstand far higher compressive, bending and tensile forces compared to wood. Steel in particular is commonly used in contiguous piling London projects and ground mat piling London methods, due to its advantageous physical properties.

Contiguous Pile Walls - Piling Contractors London

Contiguous piling is a common technique which is widely used in the creation of retaining walls. The piles are inserted in such a way that there is a gap in between. The soil between the piles can be stabilised, if required, during excavation by installing timber lagging. Or we can inject grouting into the soil before excavation which solidifies the soil between the piles.

Contiguous piling London projects include:

  • Stabilising inclines and slopes
  • Supporting Bulkheads
  • Support for Excavations
  • Support for basement or cellars
  • Rail and road cuttings
  • Underground tanks
  • Maintenance of the ground of an adjoining property



Contiguous Piling Construction Methods

Contiguous piled walls can be constructed  by our piling contractors London based by 2 different methods:

  • CFA (continuous flight auger) piling this technique involves removing the soil with an auger and at the same time pumping concrete through the auger's hollow centre.  


Rotary piling involves again removing soil with an auger after a reinforcing structure is inserted and the concrete is poured.

Creating a Basement under an Existing Property

Underpinning, which involves contiguous piling at London premises, is the process of creating a basement underneath an existing property. With this particular technique used by professional piling contractors across London, the depth of the existing foundations is increased to create the space for the new basement.

Underpinning: Is it Safe?

Used by piling contractors on London sites to strengthen building foundations for basement conversions, underpinning is a common technique in construction. Every building is unique, so our piling contractors in London ensure safety measures on each project’s merit, and underpinning is generally safe for many building types, even those located close to neighbouring properties with limited space.
