Pile foundation loadings
If the ground conditions dictate, then sometimes piled foundations are necessary. To design the piles, the pile foundation loadings need to be calculated first.
If the ground is poor, piled foundations often offer a economic solution, sometimes the only solution. Piled foundations are also sometimes chosen as an alternative to deep trenchfill foundations. These are normally needed in shrinkable clay soils when there are large trees nearby. They can be particularly useful when there is no access for large plant. Modern piling rigs can access very restricted sites that large plant can’t. Piled foundations also avoid the need to dig deep trenches which can lead to problems with nearby buildings.
Piles are either concrete or steel columns which transfer the weight of the building to a suitable depth. The depth may be to get below the poor ground or below the level affected by tree roots. The building is then supported on ground beams which span between the piles. There are a few differnt types of pile. Some are driven and some are augered.
Larger piling contractors will often be able to calculate the loadings and design the piles and ground beams. They may offer a complete design and build package. However, some of the smaller piling contractors don’t offer this service. Instead they need to be provided with the individual pile loadings and details of the ground beams. Smaller piling contractors may be more economic on some jobs, depending on your location.
