Mini Piling

Over the years, 4SP Group company London have become recognised for delivering the near impossible in comparison to other mini piling contractors in London. We specialise in the provision of mini piled systems, offering a mini piling service utilising piling rigs from 1.5 to 15 tonnes. On the majority of occasions, these do not require piling mats or specialist provisions.

Our mini piling equipment can be used for work inside buildings and in locations where restricted access piling services are needed. These occasions could include scenarios where headroom is an issue and the use of larger piling systems would be impossible.

CFA Piling

Continuous Flight Auger (CFA) piling involves drilling downwards with a hollow auger. Once the required depth has been reached, concrete is injected through the auger as it is pulled up and out of the hole. In doing so, a continuous reinforced concrete pile is formed, which stops at ground level as the auger reaches the surface. CFA piling is an efficient technique if carried out by a trustworthy CFA piling contractor in London, being used with most ground conditions and having the advantage of causing very little disturbance to surrounding areas.


Open Bore Piling

The open bore piling method allows for a greater range of sizes and depths of pile. All of the rigs at our disposal are extremely high powered which make them ideal for dealing with most ground conditions. Our bored piling machines are capable of installing pile from 150mm to 750mm to a maximum depth of 30 metres and once the required depth is reached, a reinforcing steel cage can then be installed and the pile concreted.

Below Ground Retaining Walls

A piling contractor in London would generally use this method for sites where groundwater is not an issue. Retaining walls are created by installing a series of piles close together, positioned so that they almost touch each other, leaving a gap of around 100mm between each pile, forming a robust retaining wall. These embedded piles create structurally sound walls for basement excavation. There are two main systems for creating retaining walls: contiguous bored pile walls and secant bored pile walls.


Secant Piling

This retaining bored pile wall system involves the installation of the piles in such a way that they overlap using a male and female pattern. The secant piling technique forms a watertight seal and thus provides a solid barrier against groundwater flow.


Cased Piles

These piling services work by using temporary casings to create a watertight seal through wet or unstable ground conditions down to a more stable strata of clay below, which enables us to drill beyond to the specified depth. The benefits of case piles are less over break, reduced concrete consumption, open clean pile bore for easy inspection and the ability to achieve greater depths.
