Avoiding Segregation Clause Samples

Avoiding Segregation. Concrete shall, in all cases, be deposited as nearly as practicable directly, in its final position, and shall not be re-handled for caused to flow in a manner which will cause segregation, loss of materials, displacement of reinforcement, shuttering or embedded inserts, or impair its strength. For locations where direct placement is not possible, and in narrow forms, the Contractor shall provide suitable drop and "Elephant Trunks" to confine the movement of concrete. Special care shall be taken when concrete is dropped from a height, especially if reinforcement is in the way, particularly in column and thin walls.
