Suspended Slab System IdealSlab from Ideal Foundations

How and why IdealSlab™ works

IdealSlab™ is a fully developed and certified slab system that has now been in service for many years, supporting thousands of homes.

IdealSlab™ is designed to provide a fail-safe solution to the problems encountered with differential movement of the slab/structure caused by near surface soils that are affected by either soil swell, shrinkage or by fill settlement.

IdealSlab™ is a fully suspended slab that is built on the ground without the requirements for footings excavation. The slab and the structure are fully supported on a grid of IdealPier™ driven deep into firm ground.

On "H" and "E" sites the soil is scarified to a specified depth, typically, from 600 to 800 mm. The scarification process is used to induce voids to the sub-soil strata. In the event of the soil swelling the heave forces are dissipated into the scarified cavities. This process neutralises potential damaging uplift forces acting to raise the slab and the structure off the ground. On "E" sites, this can be up to 100mm. of heave or settlement.

On sites affected by soil shrinkage or fill settlement the grid of IdealPier™ provide the required uniform support to the slab that will prevent the structure from settling differentially.

IdealSlab™ has been designed to support the house or structure without failure, irrespective of underlying reactive clay soil movement or fill settlement.
