Installing a crawl space vapor barrier is the first line of defense against high humidity and poor indoor air quality. These poly crawlspace encapsulation barriers are a thick, puncture resistant and made of a high-tensile material that stops soil moisture from entering the space from the soil. Much like swimming pool liners, these barriers encapsulate the crawlspace so that moisture cannot attack exposed wood and create mold and mildew.
Wet, damp crawlspaces are perfect living conditions for mold growth and insects. Look inside your crawlspace for the following issues:
These are signs that you have a wet, damp crawlspace that needs immediate attention. For those homes that have extremely wet crawl spaces and possibly standing water, a drainage system and sump pump can be installed prior to the liner being installed to control groundwater. In doing this, you will have a crawl space that has a water control system in place so the crawl space can be encapsulated without the worry of water seeping into the crawl space. Sealing vents and dehumidifying the crawl space are the last steps in controlling the relative humidity in your crawl space. Sealing the vents prevent the outside air from settling in the space creating condensation and promoting the growth of mold and mildew.
Excessive humidity and water vapor could lead to structural damages of the framed crawl space. Installing support piers to reinforce sagging floor joists and beams may be needed. Matthew’s Wall Anchor & Waterproofing Services is a crawl space repair specialist. Contact us today for your evaluation.
These same crawl space vapor barriers can be used on the basement walls to prevent water and moisture permeation through the wall. By continuing the vapor barrier from the ground up the foundation walls you will create a permanent vapor barrier against most water and water vapor, creating a healthier home environment.
For homes that have extremely wet crawl spaces with possibly even standing water, a drainage system and sump system can be installed prior to the liner being installed to control groundwater. Thus, the crawl space has a water control system in place so the crawl space can be encapsulated without the worry of water seeping onto the liner.
The final steps to waterproofing your crawl space involve sealing vents and dehumidifying the space. Crawl space sealing prevents the humid outside air from settling in the space creating condensation and promoting mold growth. There have been many studies done proving that a sealed crawl space creates a healthier and more energy efficient home due to the elimination of humidity fluctuations, especially when done in conjunction with a dehumidifier in the new controlled air environment.
