Is the Platipus anchor an active or a passive anchor?
A. For all intents and purposes, this distinction is almost immaterial when used in conjunction with Platipus ground anchors. In short, the anchors can be both. When the anchor is load locked under tension it is effectively active. After it is load locked into position and the top termination tightened, it becomes technically passive. The interesting attribute of the Platipus anchor is that, if after it is locked off there is further stress put on the anchor (e.g., movement in piling it is supporting), the anchor becomes active again. As the anchor is stressed due to movement, it further compacts the soil above it increasing the load it is carrying. This will continue until the physical limits of the soil and anchor system are surpassed and the anchor starts to pull free.
