-Occasionally crawlspace conditions are so saturated with moisture, either from leaky pipes, poor yard grading which drains water into the crawlspace, or just high moisture content in the air from high humidity that other options need to be explored in sealing the crawl space and putting in additional measure to ensure the constant temperature and moisture level down there. This would be achieved through sealing and encapsulating the crawl space.

--One method of sealing a crawl space is by encapsulation—lining the floor as well as the foundation walls with overlapping sheets of heavy polyethylene plastic.

-Additional strategies—including insulating the foundation walls and using the existing HVAC system to heat and cool the crawl space to the same temperature as the rest of the house, which will further increase the effectiveness of crawl space encapsulation.

-Another option for maintaining crawl space temperature and moisture levels would be to install a dehumidifier to regulate those conditions and expel any unwanted moisture from the crawl space through a ventilation line.

-Full crawl space encapsulation will give the home much better temperature regulation (throughout the home) and aside from the energy efficiency rating going up, the encapsulation will lower the cost of he associated utility bills.

Vapor Barrier:

-Vapor Barriers are a must have in our humid climate. They prevent the pooling water on the floor of the crawlspace from evaporating up into the wood under the home, and act as a barrier between the ground and the homes sub flooring.

-These barriers are normally made of polyurethane, and come in varying thicknesses. Landlock carries and installs 4 mil, 6 mil, and 12 mil vapor barriers.

-up to 50% of the air you breathe in your home comes from the crawl space, vapor barriers helps keep down all the dust, allergic issues and other harmful substances from going up through your floor and entering your home
