displacement piles

The application of prefabricated displacement piles is still the best known and most used method for foundations in the Netherlands. This is for example an extremely suitable method for laying foundations on large new construction sites. However, the application of prefabricated piles does cause noise and vibration nuisance.

The system of prefabricated piles is a so-called earth-displacement method. This means that no soil is dug out.

Generally, prefabricated piles can bear high vertical pile loads and tensile loads. They are deliverable up to lengths of 36 metres with a cross section up to 500 by 500 millimetres. Adapting pile lengths during the work is usually not possible. Depending on the pile type, however, prop piles are possible to a maximum of 5 to 1.

While driving in prefabricated concrete piles, the assessed substrata composition can be verified. Depending on the substrata condition, prefabricated piles can be driven in to the correct depth. Hence pile trimming is usually unnecessary and can be omitted.

Longer piles are pre-tensioned and reinforced with pre-stressed steel. For tension and momentum, additional traditional reinforcement can be added. All piles are supplied with an accompanying KOMO certificate, guaranteeing the quality of construction materials.
