Lateral Extent of Benefit

Cracks at ground level are instructive.

The full extent of the area affected by a partial array the Phoenix™ Machine poker treatment points is demarcated by the circumferential surficial cracking to be seen here. This means that the settlement obvious around the individual PM insertions reflects only part of its actual volume-reduction benefit.

At this site this spreading out effect is further contributed to by the presence beneath the running surface of geotextile fabric reinforcement placed between the coarse surficial fill and the underlying body of slimes.

A better estimated/appreciation of benefits deriving from a single poker insertions could be found if the volume of the regional depression was divided by the number of axes/insertions within that overall area.
