Concrete Moisture Remediation

Concrete moisture is the number one cause of flooring failure and accounts for approximately $3 billion of loss annually. Liability exposure for moisture-related flooring failures may extend to several members of the construction team, including the flooring contractor, general contractor, flooring and adhesive manufacturers and the project specifiers.*

Concrete Moisture RemediationIn the early life of the concrete slab, water is used in the hydration of the cement to produce high-quality concrete. Excessive water, water not used in the hydration process, is used to make the placement of the concrete easy. During the evaporation period, concrete must give up most of the excess water to become suitable for impervious and low permeability flooring systems.

Flooring such as sheet vinyl, vinyl composition tile, and polymer coatings and surfacing systems are referred to as impervious or low permeability. These flooring systems are very dense and do not allow for passage of moisture. When impervious or low permeability flooring is installed over portland cement concrete with high moisture content, this moisture will migrate upward through the top of the concrete slab, carrying dissolved alkalis inherently present in the concrete. These alkalis can destroy the bond between the concrete and the flooring materials. The alkalinity will become concentrated and this moist, high pH environment at the bond line can cause failure. This failure may be evidenced by disbonding, adhesive breakdown, osmotic blisters and staining. The excessive moisture may also allow for microbial growth with the related reduction in indoor air quality.

Arizona Polymer Flooring VaporSolve® Moisture Remediation Systems

VaporSolve® Moisture Remediation SystemsAPF’s VaporSolve® Moisture Remediation Systems are highly specialized epoxy coating systems formulated to isolate moisture sensitive flooring from all levels of concrete moisture. VaporSolve® systems are used when concrete has a known moisture problem, when concrete dries too slowly to meet the construction schedule, and as a preventative measure when concrete doesn’t have a vapor retarder in place and future moisture conditions cannot be predicted.

VaporSolve® 100 LP System is a specially formulated 100% solids epoxy coating designed to comply with ASTM F-3010 and is for use over concrete with high moisture levels for the purpose of isolating the concrete from moisture sensitive flooring.

The VaporSolve® Basic System consists of a single coat of VaporSolve® 100, a 100% solids epoxy. This system is applied at 16 mils over concrete that hasn’t been contaminated with reactive silicate curing compounds or densifiers.

The VaporSolve® Fresh Concrete System is a water-based epoxy formulation designed to bond to six to 24-hour-old concrete. It virtually eliminates the evaporation of water from the top of the slab, serving as the ultimate curing compound.

The VaporSolve® Ultra System consists of a water-based epoxy as a primer that gives deeper penetration and better adhesion when applied to silicate-contaminated concrete, as well as a finish coat of VaporSolve® 100, which greatly reduces the possibility of concrete outgassing.

VaporSolve® benefits include:

  • Effective with all levels of concrete moisture intrusion
  • Guaranteed adhesion over silicate contaminated concrete
  • May be applied to freshly poured concrete
  • More than 20 million sq. ft. covered with 99% success
