They are utilised for over fifty a long time and ended up developed as a cost-successful solution to build foundations through earthquakes.
Where simple pile driving leads to complete horizontal cracks in the concrete pile, calculated stress stresses could possibly be off. If The strain stresses are too high, add cushioning or lessen the duration of your hammer stroke. If far too small, it might be connected with lousy hammer general performance.
