Crawl Space Encapsulation
What this service covers
Control Ground Moisture Beneath Your Home
Exposed soil can release moisture into the crawl space beneath a home. Black Dog installs a continuous vapor-barrier liner to separate that soil from the crawl space and help reduce moisture entering from the ground.
- Continuous coverage over exposed soil
- Sealed seams and liner connections
- Details around walls, support piers, and penetrations
More Than Loose Plastic on the Ground
The liner covers exposed earth, with seams sealed to create a continuous barrier. Connections at foundation walls, support piers, and penetrations are detailed to reduce gaps where ground moisture could enter.
Care around these connections matters. The purpose is to create connected coverage throughout the treated area, including the places where the liner meets the structure.
Understanding the Crawl Space First
The layout, access, existing ground cover, support piers, pipes, and mechanical equipment all affect the installation. Photos of the crawl space and any areas where water collects help explain its current condition.
A ground-moisture liner is one part of crawl space moisture control. Standing water, drainage problems, and humidity may need additional attention beyond the liner itself.
Where this service fits
Crawl spaces with exposed soil or incomplete ground coverage. Standing water and other moisture sources also need to be considered.
