Infinity Slab removes the need for saw cut joints whilst reducing the slab thickness by 20%
What’s behind an Infinity Slab design?
The design philosophy behind the Helix Infinity Slab rests on three underlying foundations:
Elastic slab design is the safest, most durable design approach for a slab on ground.
Joints can be eliminated using Helix Infinity Slab design that provides the equivalent tensile capacity of conventional reinforcement at a ratio of 0.005 as per ACI 360 guidelines for removing joints. This relies on the formation of lightly spaced cracks that limit water ingress and fraying of the surface that is common in joined slabs and leads to slab failure and serviceability problems.
Helix provides enhanced material properties that:
a. Allow reduced slab thickness through improved modulus of rupture, and; b. Improve the crack pattern and reduce crack widths by working effectively with conventional steel to redistribute the shrinkage stress throughout the section.
