Crawl Space Repair Photo Album: What to Look For if a Crawl Space Needs Encapsulation - Lincoln City, OR
Encapsulation is the process of sealing the crawl space off from the earth and preventing water intrusion based issues. Usually, there are very obvious indicators that your crawl space would benefit from an encapsulation. Obvious signs include standing water, rotten wood posts, rodent activity, and mold growth. These can all be detrimental to your house and can lead to expensive structural repairs. When we do an encapsulation, the first step is to install a drainage system using a perforated pipe and a TripleSafe sump pump. This allows for control over the passage of water so it has a safe way to be pumped out of the crawl space. Additionally, TerraBlock insulation and a CleanSpace vapor barrier are installed. These go along the crawl space floor to seal it off and protect from water seeping through. In order to control the airflow, a SaniDry dehumidifier is installed that pulls moisture particles out of the air to promote healthier air quality. Lastly, Spray Foam is applied to the foundation walls to air seal and insulate. The purpose of this entire process is to control the environment in the crawl space so things like mold and wood rot don't have the environment to thrive in. Encapsulation is designed to create a healthy environment for your home and its occupants. Being aware of the signs of water based issues are important to know when its time to take action and save your home.
First Sign: Damaged Vapor Barrier.
If your vapor barrier looks like this, that indicates water has intruded and shifted the vapor barrier. With the earth beneath exposed like this it will allow for more water to have easy access into the crawl space and eventually the home.
Unprotected Wooden Posts.
Wood is an organic material that molds and rots as it absorbs water. This can make it become damaged to the point where the posts can no longer support your home and it will settle.
Mold and Mildew Exposure.
Mold and mildew is able to grow in moist environments. If there is water intrusion and it evaporates into the air, that increases the amount of moisture content and raises humidity for mold and mildew to thrive.
Standing Water.
The most obvious sign that an encapsulation might be necessary is standing water with no safe way to exit.
Homes Settling.
Over time the structural damage of water intrusion can become so severe that homes will settle. This means that the foundation is unstable and unsupported. This post has lifted off of its footing over the years when other wooden posts rotted and the homes floor shifted.
