Recommended Products: AlorAir® Sentinel HD55（Gold）, AlorAir® Sentinel HDi65, AlorAir® Sentinel HD55(Blue)

Crawl spaces are built with the purpose of raising the level of a house to avoid the effects of flooding. That is why nowadays, more than 35% of houses are built with it,they provide great protection from floods. However, as they are partially or fully built underground, they are susceptible to many humidity problems. Some homeowners even spend thousands of dollars yearly just to repair humidity-related damages in their crawl spaces.

Having no control over the humidity of your crawl space could lead to numerous problems led by excess moisture. You should have the proper equipment to avoid such occurrence, here are some indications that your crawl space has a higher humidity than what is regularly recommended:

Damp or humid air
Water trickling in walls
Puddles of water on the floor
Mold and mildew growth on surfaces
Rotting of wood
Water stains on walls
Musty odor
Deterioration of carpets

Being in this industry for a significant amount of time now, we have come to realize that there are still a number of homeowners that only opt to have remediation in their crawl space once damage has already been done. This could cost a huge sum of money and effort, especially if it becomes a regular problem. The most vital step to take is to invest in a prevention plan that would avoid these types of damages in your home. It would save you money and worry, and would assure you of a safe and conducive environment for you and your family, and not for infesting pests.

A very effective way to avoid all of these is to have a reliable dehumidifier. Several samples that we series.

Consider these tips:

With the main sources stated, it is also important to know how excess moisture actually moves to seep through and into your crawl space. They can easily manage their way into your home for several reasons, but the most common is having poor construction, especially in drainage and air circulation systems.

Install a rain gutter system: This will effectively collect rain water from the roof and steer it down to spouts where it will be directed to a safe drainage that is 5 to 10 feet away from your house.

Proper house grading: Make sure that your house is built around proper grading to ensure accurate drainage of water away from your house’s foundation.

Dig a trench: This is another option to keep rain water from entering your house. Just be certain that that trench can hold its form to avoid further complications.

Install a drain tile: This is actually a system of PVC pipes laid beneath the ground around a home’s foundation. Their purpose is to collect water before even entering your crawl space.

Below are ways on how excess moisture is able to get into your home; they are considered as Moisture Flow

In relation to air-transported moisture, let us take into consideration another movement of the air that contributes to high humidity in your home; this is called the Stack Effect. This occurs when warm air rises and exits the house through upper passageways such as windows or vents. This creates a negative pressure in your crawl space creating an unbalanced mixture of humidity and temperature. This pressure forces external humidity to permeate through your crawl space. This will keep on going on if not properly controlled immediately.

Capillary

Action

This is a natural occurrence around us and it applies to many things because it is all about the actual behavior of water. The idea as to how water permeates through a towel, cloth, or soil, is the same with your foundation. An effective way of preventing this is applying a capillary break such as plastic, metal, or any other impermeable material when your house is still being constructed.

Moisture/vapor

diffusion through foundation walls

Vapor is considered to be highly diffusive. Given external changes in weather that promotes a high production of vapor, it is a fairly easy job for vapor to permeate through your foundation walls and condensate to your crawl space interior. This is a very common problem, especially for houses built in concrete, as they are more susceptible to moisture absorption.

Air-transported

moisture

Especially during the summer, when many homeowners opt to open their windows and provide extra air circulation in their crawl space, air-transported moisture is highly to occur. While opening windows might provide temporary drying to your space, this will not be the same case long term. Doing it will actually increase your crawl space’s humidity that will eventually lead to wall drips and dampness.
