Flooding in basements can cause extensive damage to your home and belongings. In a wet climate, homeowners need to take precautions to prevent basement flooding and be prepared if it does occur. Follow these tips to help manage and prevent flooding in your basement.
Check and Maintain Drainage Systems
One of the main ways water gets into basements is through the drainage system around your home. Make sure all gutters and downspouts are cleared of debris so that rainwater can flow freely away from your home's foundation. Periodically check your drainage pipes and sump pump to ensure they are operating properly and not clogged. Consider installing a battery backup system for your sump pump in case of power outages or buy sump pump online if yours needs replacing.
Look for Signs of Damp or Leaks
Inspect your basement walls and floor regularly for any signs of dampness or water leaks. Look for pooling water, mould growth, flaking paint or a musty smell which can indicate excess moisture. Identify where the water is entering from and take steps to seal cracks or holes in the foundation. Make sure weep holes designed to drain water outside are not blocked. Install a dehumidifier to help control moisture in your basement.
Improve Grading and Drainage
Make sure the ground around your home slopes away from the foundation so that surface water drains away. Extend downspouts at least 1.5 metres from your home's foundation and make sure the surrounding soil is properly graded. Consider installing French drains, sump pumps or dry wells if the landscape doesn’t naturally channel water away from your basement. Laying gravel, pavement or plants around the perimeter can also help control soil erosion.
Waterproof Walls and Floors
Sealing cracks and holes in basement walls prevents groundwater seepage into your basement. Waterproof basement floors to stop moisture coming up through the concrete. Professional basement waterproofing services use sealants, membrane systems and drainage mats to create a moisture barrier. For DIY projects, paint basement walls with waterproofing paint or sealant. Replace old carpeting with moisture-resistant flooring.
Get Flood Insurance
Even with preventative measures, unexpected flooding can still occur. Get insurance coverage for sewer backup, surface water flooding, groundwater and rainfall to protect your home and possessions from water damage. Review if your valuables, finished basement and pumps/sumps are adequately covered. Understand any exclusions like flood zones. This can provide peace of mind if flooding does impact your basement.
Have an Emergency Plan
Create a flood response plan so you can take quick action in the event your basement does flood. Know how to quickly shut off electricity to the affected areas. Have a sump pump, wet/dry vacuum, mops, buckets, old towels, protective clothing and rubber gloves on hand. Move valuables and furniture out of harm's way. Understand when to contact professionals for cleanup or repairs. Being prepared can help minimize damage.
With proper maintenance, preventative measures and emergency readiness, homeowners can help protect their basement from flood damage. Pay attention to signs of dampness or leaks and take corrective action as soon as possible. Consider professional waterproofing for high-risk basements. Stay vigilant and act quickly if flooding occurs to mitigate costs and disruption.
