Which type anchors are preferred when soil conditions will hold the anchor and rocks are not a problem during installation?

• A. Cross-plate
• B. Deadman
• C. Expansion
• D. Screw

Answer: (D)

When the ground itself can hold the load and there aren’t issues from rocks during installation, a screw (helical) anchor is the best fit. It reaches its holding power by being twisted into the soil, and the helices cut into and compact the surrounding soil to develop resistance right away. This means you get reliable pull resistance with minimal digging, no extensive backfilling, and straightforward depth control. Other anchor types rely on backfill, large trenches, or a solid substrate like concrete or rock to work effectively, which isn’t necessary when the soil condition is already favorable. So the screw anchor matches the situation best because it combines strong performance with efficient, simple installation.
