Don’t put up with a damp, nasty crawlspace! These conditions can cause mold to grow and wood to rot, resulting in structural damage as well as harmful airborne mold spores. Basement Waterproofing Solutions has pioneered the field of crawlspace waterproofing, repair, and encapsulation. We’ve developed the specialized products and industry-leading training programs to transform any ‘problem’ crawlspace into a clean, dry foundation that’s an asset rather than a liability.

A crawlspace is a type of basement in which one cannot stand up — the height may be as little as one foot, and the surface is often soil. They offer a convenient access to pipes, substructures and a variety of other areas that may be difficult or expensive to access otherwise. While a crawlspace cannot be used as living space, it can be used as storage, often for infrequently used items. Care must be taken in doing so, however, as water from the damp ground, water vapor (entering from crawlspace vents), and moisture seeping through porous concrete can create a perfect environment for mold/mildew to form on any surface in the crawlspace, especially cardboard boxes, wood floors and surfaces, drywall and some types of insulation.

Health and safety issues must be considered when installing a crawlspace in the Northeast. As air warms in a home, it rises and leaves through the upper regions of the house, much in the same way that air moves through a chimney. This phenomenon, called the “stack effect,” causes the home to suck air up from the crawlspace into the main area of the home. Mold spores, decomposition odors, and fecal material from dust mites in the crawlspace can come up with the air, aggravating breathing problems (such as asthma) and creating a variety of health-related problems.

On the East Coast, it is best to finish a crawlspace with a plastic vapor barrier that will not support mold growth or allow humidity from the earth into the crawlspace. This helps insulate the crawlspace and discourages the habitation of insects and vermin by breaking the ecological chain in which insects feed off the mold and vermin feed on the insects, as well as creating a physical inorganic barrier that deters entrance into the space. Vapor barriers can end at the wall or be run up the wall and fastened to provide even more protection against moisture infiltration.

Crawl/Basement Complete Encapsulation

Basement Waterproofing Solution has transformed many basements and crawls with a complete encapsulation system. We have converted areas with dripping condensation from ceiling to floor into comfortable living space.

Santa Fe Dehumidifiers

Studies have shown that as much as 50% of the air in your home comes up from your basement or crawlspace. This air is often higher in moisture content and carries with it various allergens and musty odors. When conditions linger above 60% relative humidity for extended periods of time, mold, mildew, and bacteria growth is stimulated.

The American Lung Association, American Medical Association, and the EPA recommend maintaining relative humidity levels in the 30% – 50% range. Ventilation and air conditioning alone cannot provide the protection offered by a high capacity dehumidifier like the Santa Fe Dehumidifier. Protecting your family and your biggest investment is worth the best.

Consequences Of High Humidity

  • The ground in a crawlspace or under the basement slab remains at a near constant temperature of 50-60ºF year around. These cool surface temperatures create micro-environments where the relative humidity of the air approaches its saturation point (100%RH) and condensation (or sweating) can occur. These conditions support mold/microbial growth and cause musty odors.
  • Crawlspaces and basements are a major source of air infiltration that permeates up into the living area, transmitting odors, carrying moisture, and creating an environment conducive to molds, pests, and dust mite infestation.
  • Wet crawlspaces and basements contribute to the cupping of wood floors and the deterioration of floor joists, beams, sub-flooring, insulation, and electrical-mechanical systems.
  • Excess moisture encourages mold growth on wood and on any other organic material in some crawlspaces.
