Ground Vapour & Moisture Barrier

Excessive moisture in a conventionally vented crawl space is one of the biggest crawl space concerns. As moisture increases in or under a structure, this increases the possibility of attracting and creating an environment that supports wood destroying insects (like termites), creates a space that encourages mould growth, and makes the structure susceptible to wood rot. Additionally, the effects of excessive moisture can negatively impact indoor air quality.

The crawl space in a home may be out of sight but the effects of excessive moisture in a crawl space should never be overlooked.

Sustain Energy Solutions protects your crawlspace or underfloor. We provide moisture control by using a high-quality vapour/moisture barrier to cover the ground. This system, along with proper drainage and a form of mechanical drying will provide great moisture control protection.

Additionally, Sustain Energy Solutions can seal your vents and set up a dehumidifier.

With a moisture barrier, your home is healthier and dryer.

• Condensational moisture
• High levels of humidity
• Ground moisture vapours
• Moisture intrusion from outside of the foundation walls

If you are having problems with moisture in your home, having Sustain Energy Solutions install a moisture barrier can help mitigate this problem. You may need water management also to get the full moisture issue under control.

Common symptoms of a crawl space or ground moisture problem           

• Mould or moisture damage in the crawl space or living area
• Musty odours in the living area
• Condensation (“sweating”) on air conditioning ductwork or equipment
• Condensation on insulation, water pipes or underfloor in the crawl space
• Buckled hardwood floors
• High humidity in the living area
• Insect infestations
• Rot in wooden framing members
• Bare dirt, trash – unsightly

Why install a ground moisture barrier? 

• To reduce possibility of moisture from rising to the floor system
• Reduce an environment that invites termites
• Help prevent mould growth
• Keep insulation from falling
• Promote clean air inside house by reducing odours caused by moisture
• Temperature and humidity monitoring
• Crawl space is cleaner looking
• Correct humidity
• Dry crawl space surfaces
