Soil subsidence

The sinking of the soil caused by inclination or settling results in nuisance and/or damage.

When the groundwater level in peat polders is too low, peat oxidizes and the soil subsides, which also releases CO2.


Business pilot handling groundwater Spengen (pressure drainage)

A full-automatic pressure drainage system makes it possible for farmers to adjust the groundwater to the desired level. In summer, this means peat can be kept humid. An added benefit is that the soil is less soggy during the winter. It slows down the soil subsidence, decreases CO2 emissions and prolongs the usability of the soil during spring and autumn. It also increases the awareness of farmers when it comes to water and soil.


  • Adjustable for specific land use
  • Decreases CO2 emissions
  • Slows down soil subsidence
  • Increases utilization of ground
  • Can be applied on a large scale
