As mentioned above, as specialists in the provision of mini piled systems, we offer a mini piling contractor service utilising piling rigs from 1.5 to 15 tonnes that on the majority of occasions, do not require piling mats or specialist provisions.
Over the years, 4Site Construction and its team have become recognised for delivering the near impossible in comparison to other mini piling contractors. Our mini piling equipment can be used for work inside buildings and in locations where restricted access piling is needed since headroom is an issue and the use of larger piling systems would be impossible.
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 company which can be used with most ground conditions and has the advantage of causing very little disturbance to surrounding areas.
Open Bore Piling
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.
The open bore piling method allows for a greater range of sizes and depths of pile. Once the required depth is reached, a reinforcing steel cage can then be installed and the pile concreted.
Below Ground Retaining Walls
Retaining walls are created by installing a series of piles close together. 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.
This system is generally used for sites where groundwater is not an issue. The concrete piles are positioned so that they almost touch each other, leaving a gap of around 100mm between each pile, forming a robust retaining wall.
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.
This piling system works 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.
