Watervapor is constantly trying to leave your crawl space. It is very hard to ventand remove this condensation. A crawl space vapor barrier may be the best wayto stop the water.
Massiveamounts of water are constantly being pulled to the surface beneath your crawlspace. This process occurs 24 hours a day, 7 days a week. Just below thesurface of the dirt, this water turns into water vapor. Water vapor isattracted to warm air. The air in your family room is almost always warmer thanthe air in your crawl space. The floor insulation and wood flooring dolittle or nothing to stop the water vapor in its constant pursuit of heat.
Sewer Specialist Avon – The only effective way to stop this water vapor migration is to properly install ahigh performance vapor barrier.Many builders, remodelers, and homeowners commonly mistake low density polyethylene plastic (4 or 6 mil poly) as being ahigh performance product. This material is often used in crawl spaces, beneath concrete slabs,or as a vapor barrier on exterior walls.
Oftenthis product is manufactured using reprocessed plastic resins, scrappolyethylene, and fillers. The quality is sometimes inconsistent. Certainalkaline chemicals in soils can actually degrade the material. Small pin holescan exist in brand new material.
Sewer Specialist Avon -The better choice, and the only product the Basement Professor uses, is a high density string reinforced polyethylene vapor barrier. These products areformulated from high quality virgin polyethylene. They are extremely resistantto punctures and tears. The high quality vinyl resists alkaline soils as well.They also do a much more effective job of stopping water vapor.
Installation:Installation of crawl space vapor barriers is not an easy task. All seams mustoverlap a minimum of 12 inches and be sealed with a special pressure sensitivetape. The vapor barrier is lapped up onto the side walls of the crawl space. Itis then caulked and attached tightly to the side foundation walls with use of threequarter inch furring strips and masonry nails.
Sewer Specialist Avon -All objects (pipes, columns, masonry piers, etc.) that are sprouting from the soilbeneath your crawl space require special attention. The vapor barrier iscarefully cut around these objects and sealed with pressure sensitive tape.
Priorto installing the vapor barrier, be sure the soil is smoothed and all sharpobjects are removed. This is done because when you work on top of the materialinstalling it, these sharp objects may tear or puncture the vapor barrier.These punctures or tears could allow water vapor to escape into the crawlspace.
