One engineered foundation

Built to integrate across platforms, leg systems and project types.

From concrete platforms to modular steel arrangements, the Multiturn Helix can be configured around the soil conditions, load requirements and build timeline of the project.

MuscleSlab integration

When a project demands the strength of concrete with the speed of screw pile installation, Multiturn Screw Piles and MuscleSlab work as a combined foundation system.

The steel Multiturn Helix integrates directly with MuscleSlab's concrete platform and leg arrangements. Unlike traditional concrete footings, the combined system eliminates excavation and curing time while delivering the load-bearing strength and certification the project requires.

Steel leg systems

A foundation below the movement

The Multiturn Helix is designed to perform across a wide variety of soil types, including the reactive clay soils that cause problems for conventional foundation systems.

The helix anchors below the active soil zone. By sitting beneath the layer most affected by moisture change, it resists the forces of clay movement and provides a stable, certified foundation across seasons.

  • Solar Leg compatibility
  • Major steel leg arrangements
  • Round and square shaft configurations

Application range

From a single platform to a large-scale site.

The same foundation logic carries across residential, commercial and industrial applications.

Reactive soil performance

Designed to anchor below the active clay zone.

The problem

Standard I-beams rely on soil friction to stay in place. When soil moisture levels change, clay soils expand and contract, grabbing the beam and shifting it unpredictably.

The Multiturn response

The Multiturn Helix sits beneath the layer of soil most affected by moisture change, resisting the forces of clay movement and providing consistent foundation performance across seasons.

Why Multiturn

Five reasons the system adapts.

Universal compatibility

Works with MuscleSlab, Solar Leg and all major steel leg arrangements.

Reactive soil performance

Reduces exposure to seasonal moisture-driven ground movement.

No excavation required

Faster installs with less site disruption.

Immediate load bearing

No curing time; build on the same day.

Certified and backed by engineering

Designed in accordance with the Bekker Bulb Theory.
