Performance Foundations Information

For decades, we have provided developers, contractors, and engineers with a foundation-forming system designed specifically for building on expansive, compressible, liquefiable, or rocky soils. Our boxes — void forms set directly on grade that, when connected together, reinforced with rebar or P/T cables, and concrete placed on top, form a Performance Foundation — come in several heights to address varying soil conditions. Performance Our boxes act as a relief valve for soils to move, with the only contact area between the slab and grade being the ribs between the boxes. Less contact area means less pressure on the slab when soils shift — enabling a Performance Foundation to deliver superior results compared to in-ground ribbed slabs, deepened footings, and uniform thickness slabs. Constructibility Our system enables the outright elimination — or significant reduction — of import, export, over-excavation, recompaction, and trenching. When you don't have to dig, things get easier from the start. The boxes connect quickly, and reinforcing steel is placed with exceptional efficiency. A Performance Foundation is arguably the easiest to install of any comparable alternative. Hard Dollar Cost Savings Up to 85% less over-excavation and recompaction. No trenching or off-haul. Less concrete and reinforcing steel. Reduced building cycle time and accompanying labor costs. And with an unparalleled track record, lower future warranty reserves. A Performance Foundation delivers superior results — at a lower cost than any comparable alternative. Fault Tolerance When engineers design a Performance Foundation, they do not factor in the inherent benefits of the void area within the boxes, as current engineering software lacks fields for inputting those variables. That means every Performance Foundation carries an additional level of built-in strength that isn't accounted for in the design — resulting in an elevated degree of fault tolerance that no comparable system can claim.
