Check the drainage.

Crop projet-3

Reliable evacuation of water is a critical factor in the protection of your foundation, the belongings in your home and the health of your family. Water backups and infiltrations and freeze-and-thaw cycles that prematurely damage the foundation are among the risks that good drainage can prevent. While new urban developments often have separate sewer systems (separating stormwater and sanitary wastewater), older neighbourhoods often have a combined sewer (storm water and sanitary wastewater together), which is more likely to backup and requires more protective measures. Houses in rural areas are often equipped with a septic system and cesspool which require regular maintenance.

Our recommendations :

  1. Make sure your perimeter foundation drains (French drains) are working well. They must not be obstructed or lower than the bottom of the concrete slab. Drainage systems generally have a lifespan of 30 to 40 years. Pay special attention to their condition, because ineffective drainage can lead to major problems in the home over time.
  2. Make sure your downspouts direct rainwater well away from the home. One good strategy is to install rain barrels: they can also help you save water for the garden and lawn or washing the car.
  3. Inside the home, the drainage system should include a cleanout trap and a check valve (backwater valve) to protect the basement and the foundations.
