From soft to stiff soils: Wide coil vs. continuous coil foundations Two screw pile geometries, two load transfer mechanisms. Wide coil (TrioMax) - Each coil acts as an independent bearing plate, creating cylindrical shear surfaces. Most effective in soft or loose soils (sand, silt, wet soil), where large diameter coils provide safe resistance to the end bearing. (Note: When the coil spacing is too narrow, the behavior may approach cylindrical shear.) Continuous coil (DeepLiner) - The load is transferred by distributed shaft friction, enhanced by continuous soil displacement. Ideal for dense, stiff or rocky soils where shaft friction dominates the capacity, with only a minor contribution from the end bearing. Practical conclusion: Wide coil → concentrated plate resistance, best for soft/loose soils. Continuous coil → Distributed shaft friction, best for stiff/dense soils. Matching geometry to soil profile - and validation through site-specific load tests - ensures safe, reliable and cost-effective foundations.
