Pile Crushing: Aggregate Technologies, Inc.

Pile crushing is an entirely different beast than pile cutting. This technique is used when piles that have already been driven or poured need to be modified. The process breaks down the concrete exterior of the pile without harming the reinforcement. This is an effective way to access the rebar when the steel cage of the pile must be tied into ...

A pile cage is fitted with a frame (30) held to rebar (4) of the cage at a cut-off level (20). When a pile is cast using such a cage, a column (54) of concrete is formed between the main part of the pile (56) and a pile head (56) passing through a central aperture (40) of the frame. This column (54) can then be snapped by a mechanical grab without the need for use of hand tools in breaking or ...
