Crawl Space Repair Photo Album: Encapsulating a Crawlspace in Champaign, IL

Moisture control in a crawlspace plays a major role in preserving a home’s structure and indoor air quality. Houses with dirt/rock floor crawlspaces and open ventilation, like the one pictured here, are particularly prone to moisture problems. When excess moisture is present, it can encourage mold growth, allow spores to circulate into the living space, and negatively impact the air throughout the home. To address these concerns and safeguard the home, our team installed a sump pump encapsulation system in the crawlspace. By managing moisture at the ground level, this system helps prevent mold development and promotes a healthier, cleaner indoor environment for the homeowners.

The Problem with Crawlspace Vents

While crawlspace vents may seem helpful, they often allow humid air, temperature extremes, and moisture to enter, creating problems beneath the home. This air doesn't stay in the crawlspace-it rises into the living areas, carrying moisture and potential contaminants with it. To prevent these issues and protect indoor air quality, our crawlspace waterproofing process always includes sealing exterior vents.

Crawlspace Encapsulation

The white encapsulation liner installed on the crawlspace floor and walls is essential for moisture control. It covers exposed soil and porous block walls, which are typical entry points for ground moisture. By sealing off these surfaces, the system reduces moisture intrusion and helps maintain a cleaner, drier, and more consistent environment beneath the home.

Sump Pump

The sump pump system is what gathers all the water collected from the crawlspace and pumps it through discharge lines up and away from the home.

Extreme Cold Protection

The water discharge lines are engineered with a freeze proof design which ensures even in extreme cold weather, water is being pumped out of the crawlspace.
