Should the pilot hole be drilled for the entire depth of the anchor, or should the anchors be driven for the last 18″ (.5m)?
We have seen installations with both methods, depending upon the soil. In some very hard, slippery soils it was most effective to drive the anchors a bit beyond the end of the pilot hole if possible. But sometimes it is not possible, and in these cases it is best to do a good job of back filling and compacting prior to load locking.
