Have you consistently noticed dampness on a concrete slab in your building? Does the flooring in your building show signs of vinyl and epoxy bubbling or glue re-emulsification?
In Arizona, slab-on-grade foundations are common in commercial, warehouse, retail, and industrial settings. Slab moisture problems stemming from our clay-rich expansive soils are also quite common. If your concrete slabs are constantly wet or showing signs of slab heave, the underlying cause could be water vapor infiltrating from below the slab.
At Arizona Foundation Solutions, we've spent decades perfecting remedies to issues caused by water vapor intrusion, targeting not just the symptoms, but the source. Utilizing our proprietary MoistureLevel® Smart Foundation System, we'll eliminate the causes and damaging effects of your foundation's wet concrete slabs.
Why is your slab on-grade foundation wet? Moisture vapor and liquid water is pushed upward from vacuum pressures in the sub-slab (the stack effect). Contributing factors can include voids under the foundation, groundwater from a high water table, irrigation systems, and damaged pipes. Excess water in the concrete from initial construction (referred to as "water of convenience") is another common scenario, caused when the water in the concrete doesn't properly bind with cement particles. Remember, concrete is a porous material!
It's important to diagnose a water vapor problem correctly. Foundation settlement can be confused with foundation heave, and the underlying causes of each and their proper solutions vary widely. Traditional water vapor mitigation solutions are not ideal, involving the installation of a sealer on the top side of the concrete slab. When this teqhnique is applied, hydrostatic pressure will push sealers off and cause them to fail over time. The problem can be exacerbated when tile flooring or other flooring is placed on top of concrete slabs, effectively trapping in moisture. This can lead to adhesives failing, coatings de-bonding, and other expensive damage. In general, using sealants to solve a vapor intrusion issue is at best a temporary remedy, not a long-lasting solution.
How it Works - Our foundation repair technique borrows from reliable radon mitigation technology, using a fan and plastic pipe to create air movement and suction on the under-slab soil. Introducing outside air to the damp soil causes evaporation, making it possible to reduce soil moisture content and mitigate damaging soil expansion. Designed with protections to minimize any over-drying near the footing area, MoistureLevel® Smart Foundation System also has a smart mechanism that monitors soil moisture content and protects from over-drying.
Our system is innovative, proprietary, and proven, providing a less intrusive, cost-effective solution to a complex problem in commercial foundations.
