Why is proper drainage so important on Vancouver Island?
*
-During heavy rainfall, or when the ground in saturated, the water level around your foundation rises
-The accumulated water creates hydrostatic pressure on the foundation walls. The deeper the water, the greater the pressure
-This pressure can force water through cracks/gaps in the foundation walls, creating basement leaks and flooding

-Implementing property drainage systems like perimeter drains and sump pumps are helpful for removing the excess water around the foundation
-Waterproof membranes around the exterior perimeter of the foundation can also greatly reduce moisture penetration
-Although less effective, waterproof coatings on the interior walls of the foundation can help stop water from seeping through
