About Us
We provide developers, contractors, and engineers a slab on grade foundation forming system designed specifically for multi family or light commercial structures built on expansive, compressible, liquefiable, or rocky soils. Our ‘Vboxes’ – void forms set directly on grade that, when connected together, reinforced with either rebar or P/T cables, and concrete placed on top form a ‘VoidCore Slab’ – come in several heights for different soil conditions (see Products page).
Key Advantages
Performance
Our 'Vboxes' act as a relief valve for soils to move, with the only contact area for the slab and pad being the ribs between the boxes. And, less contact area means less pressure on the slab when soils move, enabling a VoidCore slab to deliver superior performance when compared to in-ground ribbed, slabs with deepened footings, as well as uniform thickness slabs.
Constructibility
We enable significant reductions in things like import, export, overex, recompaction and trenching/digging. And when you don’t have to dig in the dirt, things get easier right out of the chute. In addition, our boxes can be quickly connected, with reinforcing steel placed with incredible efficiency. A VoidCore slab is arguably the easiest to install vs. any comparable alternative.
Hard Dollar Cost Savings
Up to 85% less over-ex, recompaction, trenching and off haul. Less concrete and steel reinforcing. Reductions in building cycletime and accompanying labor costs. And, with an unparalleled track record, decreases in future warranty reserves. A VoidCore slab will not only deliver superior performance, it will do it for less cost.
Fault Tolerance
When engineers design a VoidCore slab, they don't utilize the inherent benefits of the void area in the boxes (a definite ‘relief valve’ for heaving soils) because current software does not have fields for inputting those factors. The net effect is that a VoidCore slab has an additional level of built-in strength that’s not accounted for, leading to an uptick in fault tolerance.
