- Stop the Water Source: once determined, it’s safe to enter, identify and address the flooding source; if the flood is caused by a burst pipe, shut off the water supply to your home immediately. Locate the main water supply line and turn it off: typically, you can find it in the foundation wall near the front side of your property.
- Remove Valuables and Electronics: Safely remove any valuable items, furniture, and electronics from the flooded area. Place them in a dry and secure location to minimize damage. Take extra caution when handling electrical devices in contact with water.
- Begin Water Removal: Depending on the severity of the flooding, you can start removing water using a wet/dry vacuum, a submersible pump, or even buckets. Be cautious when using electrical equipment near standing water and follow safety guidelines. If the flooding is extensive, it may be necessary to contact a professional water damage restoration company.
- Dry and Dehumidify: After removing as much water as possible, focus on drying out the basement. Open windows for ventilation until the setup of fans, and industrial dehumidifiers to help circulate air and reduce moisture levels; it’s important to note that windows and doors should be closed throughout the dehumidification process. If rendered by an IICRC-certified professional, the basement drying equipment would help to thoroughly dry all water-affected personal belongings, flooring, wall and ceiling infrastructures to prevent mold growth and further damage.

What causes water to enter the basement?

To understand how and what causes water to enter the basement and cause basement flooding, we’ll start by identifying the fundamental principles of flooding as indicated below:
Flood types?
Coastal flooding, riverine, areal, catastrophic, Fluvial floods, flash rainstorms, melting snow, ponding or pluvial and urban flooding.
Flooding source entry points:
1. External flooding source points:
cracks in the foundation walls
footing area where the floor meets the wall
cracks in the foundation floor
basement windows or doors
sealants, furnace & bathroom vents
electrical panel wiring coming into the property
Hydrostatic Pressure refers to water pressure from heavy rainstorms and downpours that increase water weight throughout the earth generating downforce gravity through the soil. This pressure occurs under the basement foundation floor and surrounding walls. Some common areas are cove leaks through the footing wall-floor joint areas. . Water pressure can, in time, also shift foundation blocks that have formed gaps or window wells that lack proper irrigation. Where the real catastrophic damage occurs, water enters the property and begins pooling on the cement floor foundation, rising in level as more water finds its way in. Left unattended, the entire basement eventually floods and causes irreversible damage to the property. In countries where the temperature drops below freezing, thaws and freezing cycles put tremendous stress on the foundation and cause it to form cracks that ultimately allow the pressure to get released into the property in the form of floodwaters.
2. Internal flooding source points:
- burst pipes
- sewage backups
- water build-up due to faulty plumbing
- weeping tile blockage
- hot water tank failure
- appliance water lines
- sump pump failure
Sometimes the water source can be easy to identify, such as the cases of overflowing sinks and toilets, backed up sewers, or overflowing sump pits. However, it can be hard to locate because it happens within the structure itself. This can include burst pipes inside walls and leaky water pipes.
The three primary flooding factors:
- downslope factors – Water flowing downhill.
- upslope factors – The amount, location and timeframe it takes water to reach a drainage channel due to precipitation.
- coincidences – Extreme weather changes that create heavy amounts of water in a short period of time.
