How does moisture enter the basement?

You may know what factors cause dampness under the ground, but here are some common methods that we examine:

– Diffusion of moisture vapor through the base walls or floor upwards

This steam moves upwards and enters the dry parts of the ground. The amount of moisture that reaches the basement, depends on factors such as concrete porosity and vapor pressure.

– Structural cracks

Another way that water reaches in the ground layer is through the pressure exerted on the foundation.

– Settlement of soil, blocks, beams that are not connected to each other in the floor, these can cause water to reach into the basement. If the cracks are sealed, this problem will also be fixed.

– The phenomenon of capillary suction

Capillary suction happens when moist soil comes into contact with the concrete of the basement wall.

At this time, the moisture penetrates into the concrete through small pores and creates rings of moisture on the basement wall.

– Air leakage


When warm air rises, negative pressure enters the ground. During this process, moist air escapes through cracks and holes.

How to control moisture underground?

The lack of moisture under the ground is very important for the health of your building, so you should consider the best ways to control it.
In some cases, we see that the ground is dry, but this water vapor can be in the air for days and weeks. To be sure of the humidity level, just get a hygrometer and measure the humidity level.

– Internal drainage system

In some climates, summer is not hot and dry. Sometimes it rains and the rain water increases the humidity level.

To prevent water from accumulating in the basement, you must provide a proper drainage system.

– Waterproofing foundation cracks

As long as there are cracks in your basement, be sure that water vapor and even liquid will pass through these cracks and enter the basement, so fill these cracks with air.

In order to waterproof the cracks, we recommend the biobased Logic Water. This product protects your building with a twenty-year warranty.

– Keeping windows closed

You might think that if you leave the windows open, the humidity will go out.

But opening the windows in the summer season not only does not let the humid air out, but also makes the air more humid.

But if you have to keep the windows open, do it early in the morning or in the evening when the air temperature is less. As you know, cold air carries less moisture with it.

– Check gutter and downspout

Gutters act as exterior waterproofing, If the gutters are clogged, they will not function properly, so make sure your building’s drainage system collects water from around your home and directs it outside.

With all these points that we have said, if you are worried about what happens in your basement during the summer season, contact our experts right now.
