Why is Ground Gas Protection Required?

​

Harmful, naturally occurring below-ground gases and vapours pose a growing challenge for the Construction Industry.

Radon, Carbon Dioxide, Methane and VOCs (Volatile Organic Compounds such as Hydrocarbons) are a risk to health and new buildings have to use appropriate materials to keep these gases out of the structure.

​

What is Radon Gas?

​

Radon is a naturally-occurring radioactive gas that can cause lung cancer. Radon gas is inert, colourless and odourless. Radon is naturally in the atmosphere in trace amounts. Outdoors, radon disperses rapidly and, generally, is not a health issue. Most radon exposure occurs inside homes, schools and workplaces. Radon gas becomes trapped indoors after it enters buildings through cracks and other holes in the foundation.

​

Is Methane Gas harmful to humans?

​

High levels of methane can reduce the amount of oxygen breathed from the air. This can result in mood changes, slurred speech, vision problems, memory loss, nausea, vomiting, facial flushing and headaches. In severe cases, there may be changes in breathing and heart rate, balance problems, numbness, and unconsciousness.

​

What is Carbon Dioxide (CO2)?

​

Carbon Dioxide; commonly referred to its periodic compound, CO2; is a toxic, asphyxiating gas. Its maximum permissible levels 0.5% by volume for long term exposure and 1.5% by volume for short term exposure.
