-Best method in limited work height
-Less noise
-Less vibrations (below the Dutch limit of 5,6 mm/sec)
-Long piles with small equipment
-Efficient energy impact
-100 % straight pile
-Concrete protected by steel casing
-100% reliable foundation
Top drive piling:
-Cheaper piles
-Fast installation
-Simple Drop weight
-Higher frequency when using a hydraulic hammer (app. 55 blows/minute)
Displacement drilling:
-No noise
-No vibrations
-High friction of the pile due to displacement this results in smaller diameter casing
with higher bearing capacity
CFA drilling:
-No noise
-No vibrations
