The EK200LS Cased CFA from CZM features:

• Double rotary head. Rotary A drives the auger clockwise. Rotary B drives the case counter clockwise
• Dirt comes out os windows in casing coupling
• In primary drilling a first row of continuous flight auger piles are made.
• In secondary drilling a second row is made between the primary row with the casing shoe cutting 1-1/2 inches into each of the primary piles, secant to them.
• Following, H-beams or cages are introduced in secondary piles.

System Advantages:

• Very fast method. Similar to CFA and Auger Cast, the EK200LS Cased CFA typically produces 12-16 piles per day, or more
• A guide formwork is made so that each pile is drilled in the exact spot, secant to one another
• The perfect guidance and rigidity of the single piece casing allows for perfect verticality and excellent sealing
• The 4-inch swivel and auger inner passage allows for the use of grouting or concrete
