  10. VENTILATED MICROPILE FOUNDATIONS • Founded on micropiles • Piles cut off above the ground level • Base floor supported directly on the piles • Fully ventilated crawl space • No separate footings • No frost insulation • No underdrains • Very fast installation • Installation possible in all kinds of soil Hannu Jokiniemi/Corporate R&D

  11. A ROW HOUSE FOUNDATION IN VIIKKI, HELSINKI • 68 steel pipe piles ø115 mm / ø75 mm • Framework from hollow section steel profiles • Framework joints by bolts • Framework prefabricated in workshop • Framework zinc coated • Foundation installation in 3…5 days Hannu Jokiniemi/Corporate R&D
