Some of the most common causes of basement flooding in Southern Ontario include heavy rainfall, inadequate drainage systems, aging infrastructure, and improper grading of land.

Heavy Rainfall:

Southern Ontario experiences heavy rainfall during certain times of the year, which can result in flooding. This is because the drainage systems in some areas may not be able to handle the volume of water, which can result in basement flooding.

Inadequate Drainage Systems:

In some cases, the drainage systems in Southern Ontario may be inadequate or poorly designed. This can result in water accumulating in low-lying areas, which can lead to basement flooding.

Aging Infrastructure:

Many of the homes in Southern Ontario were built several decades ago, and the infrastructure may not be able to keep up with modern demands. For example, old sewer lines and stormwater systems may not be able to handle the volume of water that is generated by heavy rainfall.

Improper Grading of Land:

The grading of the land around a home is important in preventing basement flooding. If the land around a home is not properly graded, water can accumulate around the foundation, which can lead to basement flooding.

Sewer Backups:

Sewer backups can occur when there is a blockage in the sewer line. This can result in water backing up into the basement of a home.

Frozen Pipes:

In the winter months, pipes can freeze and burst, which can result in water entering the basement of a home.
