Practical formwork • Quick stripping and assembly of the two shells
• Wheels reduce the use of handling equipment on the casting yard
Simple casting • Min. area required to cast one unit of height C:
1.65C2
• Min. compressive concrete strength recommended at stripping:
10 MPa for all units sizes
• Typical daily standard production rate: one unit per mould
Minimum storage and easy handling• Forklifting is effective for handling small to medium-sized units
• Large units are handled by slings
• CORE-LOC™ units can be stored nested on one or more levels in a ‘‘herringbone’’ fashion
• Min. area required to store 10 units on 1 level:
5.2C2 where C = CORE-LOC™ unit height
• Min. compressive concrete strength recommended for handling units:
25 MPa for units less or equal to 8.5 m
3 and 30 MPa for sizes above 8.5m

Fast placement
Principle: each unit placed in a random attitude to obtain the specified packing density, using GPS.
Placement rates
