One of the questions we frequently receive in our capacity as piling contractors is “how deep does foundation piling actually go?” The truth is that there is not a definite answer because depths vary based on several different factors. The type of pile used is just one thing that influences depths. Because we use mini piling, Grundomat piling and a series of other techniques, we advise on depths job-by-job.

Foundation piling is a deep piling technique used on larger, heavier forms of construction and, the taller the build, the deeper we go. Because we have experience in mini piling, which has applications for smaller builds in Bolton’s domestic sector, some depths are comparatively shallow. With foundation and Grundomat piling for large builds, like high-rise flats, commercial premises and hospitals, our piles go deeper.
Pile foundations support physical structures by transferring their weight load into the surrounding soil and rock. The heavier the above-ground weight of a structure, the deeper we need to go with our foundation piling. Other influencing factors include ground and soil conditions, the proximity of the new build to existing structures, and the piling method that is best suited to the build itself.
Soil conditions on your Bolton site determine our choice of traditional foundation piling, mini piling, Grundomat piling or any alternative system. We can encounter sand, clay, gravel, peat, chalk and rock during our soil investigation. Weaker soil types, like sand, clay and peat, need deeper piling. Contractors will analyse conditions for you, and local authorities may have records for soil types in your area.
All this knowledge must come to the fore before we can make the calculations needed to choose a type of piling.
While much of our work takes place in the local domestic and commercial sectors, driven or bored foundation piling systems have applications in civil engineering, especially in the construction of walls, towers and bridges. As discussed above, how deep the piling goes will very much depend on how much above-ground weight needs to spread through the foundations.
Piles come in steel, concrete or timber form. Steel tube piles work best for the heaviest loads, concrete is a versatile choice for most ground types and timber is often the preferred pile for stabilising smaller builds with restricted access.
Pile types used on projects in Bolton include:
Known as replacement piles, this system sees soil removed from the ground and holes filled with concrete. Piles reach 40m in length and work well in confined spaces.
Often used to strengthen existing builds using a method called underpinning, mini piles are between 100mm and 600mm in length but can extend to depths of more than 50m.
This is an air-driven system used on sites in Bolton with restricted access or in an underground location to limit vibrations. Again, depths can reach around 50m.
Our piling contractors have experience in all systems and excel in bored foundation piling, mini piling and Grundomat piling work. Until we visit sites in Bolton, we can’t really advise you on which method will work best for stabilising the build. What we can do is promise you our professional brand of workmanship, a prompt survey and a streamlined response.
That’s because Piling Solutions North West has built its reputation on quality of service and high-end customer care.
