Grundomat Piles

The Grundomat method is an air driven piling system, which uses compressed air to drive the piles. The compressed air can be supplied from outside the piling area, using very small machinery and generates minimal vibration making it a useful technique for restricted access sites and in underground environments. Grundomat bottom driven mini piling uses compressed air to drive steel tubes ranging from 100 mm to 150 mm diameter driven until a pre-determined set is reached. Extra tube sections can be welded together as required until the design depth is reached.

Construction sequence

Fields of application

  • In confined, narrow and difficult to access working areas, including basement and underground sites 

  • At locations where noise or vibrations need to be limited

  • Small house extensions; garden rooms, orangeries, conservatories, porches in residential areas

Environmental impact

  • Minimal vibration generated

  • Limited noise pollution 

  • No soil removal 

  • No piling rig required

  • Mobile method (the compressed air can be supplied from outside the restricted area with little disruption)
