The heavy rain season is coming to Canada. Homeowners should consider the risks of water infiltration and sewer backup in basements. These problems can seriously damage buildings. In addition, the quality of water and indoor air may be compromised. Be prepared for this situation.

Risks associated with heavy rain

In the event of heavy rain, the ground may become saturated. In this case, water absorption becomes impossible. The water will then accumulate and infiltrate the basements. When the humidity persists, the foundations can be affected. Property damage can be significant. Here is an overview: weakened walls; warped floors; mold growth.

In addition to water infiltration, sewer backup can also occur. This happens when rainwater and wastewater can no longer be properly drained. In addition to structural damage, all of this can also cause health problems for the occupants. Moreover, it should be noted that water infiltration and sewer backup can lead to water contamination.

Water contamination

In the event of water damage, the latter can be classified into three categories. A good understanding of them is essential for a correct risk assessment:

  • Category 1: This water comes from sanitary sources. It is drinking water that does not pose a health risk. It can come from an overflowing sink or from broken pipes. Be careful though, as this water can become harmful when it flows and comes into contact with various materials.
  • Category 2: This is grey water that comes from contaminated sources. It can cause discomfort and illness if consumed. This is due to certain microorganisms it contains. This can be the overflow of a dishwasher, a washing machine or toilet bowls (without faeces however). It is best to avoid any direct contact (and ingestion).
  • Category 3: This is highly contaminated black water. This contains dangerous pathogens. It can come from sewers, wastewater problems or even the overflow from a lake or the sea. Black water poses a serious health hazard. It requires immediate intervention.

How to anticipate?

It is wise to anticipate the risks of water infiltration and sewer backup. Preventive measures must be taken before heavy rains. Check the drainage around the building. It is particularly necessary to clean the gutters. This prevents the risk of overflow. The land around the building must be well leveled. It is necessary to ensure that the water is directed away from the foundations. The basement must also be inspected. This allows you to detect signs of humidity or infiltration. As soon as the water changes appearance or smell, it must be tested without delay.
