This moisture and hydrostatic pressure penetration are major causes of damage and ruination of flooring in the athletics, commercial, and residential flooring industries, costing over a billion dollars annually.
Further, it is often not feasible to wait for a concrete slab base to reach optimal conditions with to relative
humidity, pH, hydrostatic pressure, and
efflorescence before a wood,
polyurethane, urethane, polyvinylchloride, vinyl, carpet or padded flooring surface is installed above the concrete slab base, depending on project specifications and completion timelines.
Suspended wood flooring surfaces used in the athletics industry warps, bends, bows, and / or rots when moisture and hydrostatic pressure penetrate through the concrete slab or deck base and are absorbed by the wood, resulting in a failure of the suspended wood flooring surface.
When wood flooring surfaces used in the athletics industry are directly adhered to the concrete slab versus suspended, the wood flooring surface often delaminates from the concrete slab base, causing buckling of the wood flooring surface.
As the moisture continues to penetrate the directly adhered wood flooring surface, it too will ultimately warp, bend, bow, and / or rot, resulting in a failure of the flooring surface.
These flooring surface failures are not only costly to repair, they are also potentially the cause of serious injury to those who step,
plant, and / or
push off of areas of failure.
This buildup of moisture and pressure creates loose areas and bubbles that require costly repair and require full flooring
surface replacement as the condition worsens.
Moisture and hydrostatic pressure penetration also cause problems in commercial and residential flooring industries.
Costly repairs are necessary in these instances, and eventual replacement of the tile flooring surface may be needed as the
moisture penetration issues worsen.
Injury is also a very real possibility in these contexts, as those walking or running over failing areas may suffer falls and related injuries, such as breaks and sprains.
Residential and commercial carpet flooring surfaces experience rippling, rot and / or ruination of the carpet and padding flooring surfaces where moisture penetrates through the concrete slab and builds below the carpet and pad.
In addition to cost concerns, in residential and commercial office settings, there are health concerns related to mold growth below and within the pad and carpet.
In these instances, one may not only encounter significant cost of replacement, but also significant expenses relating to mold abatement and healthcare.
Methods incorporating these products have potentially negative health and environmental impacts, are very costly to implement, do not exhibit optimal performance, and have significant drawbacks in terms of application and usage.
Urethane, vinyl, and
epoxy formulated products have varying levels of VOC's that are harmful to both individuals and the environment.
Further, liquid and
solid waste containing urethane, vinyl, and
epoxy formulated products often requires disposal in dedicated landfills with accompanying disposal fees.
These urethane, vinyl, and
epoxy products also have a limited pot life, or working time, and greater waste is generated when these products are selected to prevent moisture and hydrostatic pressure penetration from a concrete slab or deck base.
Additionally, urethane, vinyl, and epoxy formulated products are very expensive and the cleaning solvents required for tools used to apply these products can be equally expensive.
Unit costs for methods incorporating these products are 50% to 80% more expensive than those used in the method proposed herein.
There may also be additional costs incurred in connection with disposal of these products as discussed above.
Further, urethane, vinyl, and epoxy formulated products are very brittle.
As the concrete base slab cracks from expansion, contraction, and
ground movement, these products crack, thereby creating a
route for moisture and hydrostatic pressure penetration and loss of the concrete slab or deck base seal.
In instances where the flooring surface is anchored to the concrete, the brittle nature of these products may result in compromise to the seal around the anchor as the anchor is installed.
In addition, urethane, vinyl, and epoxy formulated products have a short pot-life, or time of workability, often of less than thirty minutes.
Once the urethane, vinyl and epoxy formulated products' components are mixed, they have to be immediately applied or they become waste.
However, this type of plastic
vapor barrier is not always successful in preventing moisture and hydrostatic pressure penetration from entering the poured concrete.
In addition, this plastic sheeting does not prevent the moisture and the concrete from penetrating out of the concrete through the capillaries and negatively interacting the flooring surface, either directly or not directly adhered to the concrete.
