Permanent Cased Drilled Piles

These piles are required when ground conditions are so unstable that drilled holes cannot safely be stabilized with drilling slurry or where loss of ground must be controlled. Casings offer 100 percent stable excavation for the full length of the drilled shaft. Casings can be installed by high capacity impact or vibratory hammers when noise and vibration are of no concern environmentally or to surrounding structures.
