AIS Houston - Crawl Space Remediation Services
AIS Crawlspace Remediation
There may not be an area of the home that creates a bigger hazzard to the occupants health than that of a typical crawlspaces.

Most homes with crawlspaces are not properly insulated for moisture control and this can pose health concerns for the occupants, especially children.

Lack of properly sealed and insulated crawlspace can allow dealdy and odorless gases to affect occupants.  It can also become breeding ground for insects, rodents and mold.  In addition, it could cause damage to the foundation and the floor system.
Top Quality Materials
AIS combines the use of heavy duty liners (not the cheap garbage bag-like) and closed cell foam to create AIS Houston - High Quality Crawl Space Encapsulation clean and safe crawlspace that permanently solves this problem for a relatively low cost.

The crawl space under the floor of a home is a ticking time bomb of potential problems.

That short, basement-like space with the dirt floor that many homeowners would rather forget is in many instances a welcome home to moisture-loving pests like carpenter ants and termites as well as health-jeopardizing problems like molds, mildews and soil gases.
The Stack Effect
Crawl spaces are often damp, humid spaces due to water runoff from rain, irrigation systems or an elevated water table. While the building code requires crawl space ventilation, this ventilation does virtually nothing to mitigate moisture problems and can actually make moisture problems worse.

Houses operate like chimneys.

If you introduce a hole at the bottom of a chimney, a natural draft ensues as air exits the top of the chimney.

This is called stack effect.

Attic ventilation is the top of the chimney and crawl space ventilation is the bottom.

As air is drawn up through your house, moisture, mold spores, odors and soil gases from the crawl space find their way into the living space.
The Solution
Crawl space encapsulation involves sealing the under side of the floor with a Closed Cell Polyurethane spray foam appliation and covering the ground using a tough 15-20 mil, reinforced polyethylene sheeting (not some thin 6 mil poly) taped carefully at the seams and adhered to the top or bottom of the concrete foundation wall.

Sealing up all ventilation entering the crawl space is a specification 'if' it is decided that ventilation is not neccessary for mechanicals. Sealed below this sheeting are soil gases, moisture, water vapor and odors that typically would be drawn up into the living space above.
