Radon in houses? Why do people get it?

Radon in houses is a common problem in Sweden and is usually caused by soil radon that penetrates through the foundation. For more than 20 years, we have specialized in solutions and ready-made action packages for soil radon.

The reason why radon gas enters the house is because the house is heated. Creating a warmer climate indoors than outdoors creates a negative pressure that draws in air from outside and also air from the ground under the house. If you also have an exhaust fan in the house, the negative pressure is further enhanced.

The greater the temperature difference between outside and inside - the greater the negative pressure created. The effect of this can be observed on a cold winter day when the cold outside air flows in through window frames, cracks and other leaks.

Common points where radon gas penetrates can be around sewage pipes, water pipes, electric cables that come through the base plate, dry cracks between wall and floor and clean cracks in the floor. All of these are easily sealed in our package attached gastight sealing compound.
