3: The Flooded Basement Restoration Steps

The Restoration process of rebuilding the basement after a flood to its pre-loss condition can be daunting. However, with careful planning and execution, homeowners can effectively restore their basement spaces. In this article, we will discuss the essential steps involved in the rebuilding and restoration process, ensuring a successful transformation of your basement.

  1. Restoration Assessment and Planning:

    The first step is to assess the extent of the damage caused by the flooding. Thoroughly inspect the walls, floors, and ceilings to identify areas that require repair or replacement. Create a detailed plan that outlines the specific tasks involved in the rebuilding and restoration process. Consider consulting with a professional contractor who specializes in basement restoration to obtain expert advice and guidance.

  2. Structural Restoration:

    Begin the restoration process by addressing any structural issues in the basement. Repair or replace damaged walls, floors, and ceilings. This may involve removing water-damaged materials and installing new ones. Ensure that all repairs comply with local building codes and safety standards.

  3. Electrical and Plumbing Systems:

    Examine the electrical and plumbing systems in the basement for any damage caused by the flooding.

Install appropriate window treatments and decorative elements to create a welcoming atmosphere. Consider incorporating storage solutions to optimize space utilization in the basement.

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:

  1. downslope factors – Water flowing downhill.
  2. upslope factors – The amount, location and timeframe it takes water to reach a drainage channel due to precipitation.
  3. coincidences – Extreme weather changes that create heavy amounts of water in a short period of time.

Reference the diagram below to see the most typical sources of water penetration that can occur in a home.

How to Prevent A Basement Flood

Key preventative measures you can take to prevent your basement from flooding.

  • Schedule Plumbing Maintenance by a licensed plumber
  • Schedule your HVAC Appointment
  • Maintain all water connected appliances by an Appliance Technician
  • Schedule a waterproofing specialist for a foundation inspection
  • Schedule Sump Pump maintenance
  • Schedule Sewer backup valve maintenance
  • Schedule a consultation with a water leak detection specialist
  • Install water and flood detection sensor systems
  • Maintain and clean gutters and downspouts
  • Consult with an Insurance specialist to better understand your coverage
  • Inspect the perimeter of the property for cracks and seal
  • Slope ground downwards & away from the foundation of the property
  • Always have a second opinion by a second party Water Damage Expert before conducting a basement repair.

How to ensure your grading is suitable around the basement exterior perimeter?

To ensure water does not enter the basement It is generally acceptable to have the earth around your house slope an inch per foot as you go further away from the premises. This should continue for at least 6-8 feet. Soil with 20-30 % clay content is best. Avoid using soil that is sandy or abundant in organic matter.


How to ensure your grading is suitable around the perimeter

Should windows below grade have window wells?

It is important that you have window wells that go below the window line and have proper drainage systems to back them up. Generally, water flow is diverted to a perforated pipe. This pipe leads to a sump pit which has a sump pump in it. The pump diverts the water back out of the house and away from the foundation.

How to maintain your Eavestrough and downspout?

It is actually very inexpensive and easy to do and will save you headaches in the future. The sole purpose of eavestroughs and downspouts is to control and divert excess rainwater to a proper location that can handle offloading this water safely away from the foundation walls. Once these stop working as intended, you are risking pooling and new channels of water going into areas that are not prepared to handle excess water. This can create slow degradation of foundation walls which will in time form cracks and provide the water with a new way to enter your property and at times create catastrophic water damage by flooding.

Eavestrough and downspout maintenance steps to prevent flooding:

  1. Clean gutters twice a year to remove debris.
  2. Seal any leaks or cracks.
  3. Ensure proper slope for drainage.
  4. Consider installing gutter guards.
  5. Trim overhanging branches.
  6. Secure downspouts and extend them away from the foundation.
  7. Redirect water with extensions or splash blocks.
  8. Inspect after storms for damage or clogs.
  9. Consider professional inspection if unsure or for significant damage.

How to prevent a basement sewer backup during heavy rains?

Running your dishwasher, washing clothes, taking showers are all actions that put a strain on your sewer system. Combined with heavy rainfall going into the main storm sewer lines will likely cause sewer backups to occur right back into the property. It is always a good idea to install a backwater valve (it is a device that prevents public sewer content from spilling back into your house). If you have one installed already, be sure to inspect and maintain it regularly. If you’re unsure of how to do this, watch the video below on proper backwater valve maintenance steps.

How to avoid clogged drains and prevent a sewage backup?

The top reason for the basement flooding is due to sewer line backup. This often happens when the main sewer lines get clogged up. Although sometimes it happens beyond our control and through the city sanitary lines, the most common instigator is our lack of filtering what we pour down our drains. Grease, oil, and fats do not mix with water very well. As a result, when they are poured down the drain, they do not get washed out easily. Once they settle on the walls of the pipes, they dry up and begin forming a blockage. Eventually, that block chokes the pipe and creates a full clog. Once this occurs, the water you pour down the drain has nowhere to go and begins flowing back into the house pipes, finding exits through floor and shower drains, toilets, and even sinks. Often with gravity, this happens in the lower point of the house which is the basement floor drains. The best way to prevent this from happening is to collect the oils and fats we cook with and throw them into the garbage inside a water-sealed bag. Municipalities that offer Organic Recycling programs will accept these in their “Green Bin” program.

What are cracks and holes in your basement foundation walls?

Basement Foundation Crack Injections

Here’s another way water can enter the basement; As buildings settle and shift, cracks in the foundation are unavoidable. They are a prime source for water to enter the foundation unexpectedly. Make sure to regularly monitor for cracks in the foundation, shifts in blocks and other natural deteriorating factors to your basement foundation walls. Areas in the foundation where the largest amount of stress on the building occurs are most prone to have cracks form (middle of the foundation on a sloped hill is generally the highest stress location). Areas where heavy freezing and thawing occur also become prone to floor cracks due to heavy shifting with the climate changes.

What is a Flooded Basement?

flooded basement refers to a basement that is prone to or has been affected by flooding.

  • A basement is an underground space typically found in residential or commercial buildings. It is often used for storage, utility systems, or additional living space.
  • Flood basements are characterized by their susceptibility to water damage, usually resulting from heavy rain, melting snow, rising groundwater levels, or plumbing failures. When water enters a flood basement, it can cause significant damage to the structure, as well as any items stored within it. Common problems associated with basements include water damage to walls, floors, furniture, appliances, and electrical systems.
  • To mitigate the risks associated with a leaky basement, various preventive measures can be taken. These may include installing sump pumps to remove water, applying waterproofing coatings on walls and floors, using moisture-resistant building materials, ensuring proper drainage systems around the foundation, and elevating valuable items above ground level.
  • If a basement frequently experiences flooding or is located in a high-risk flood zone, it may be necessary to take more extensive measures such as installing flood barriers, improving the grading of the surrounding landscape, or even considering basement waterproofing techniques that involve excavation and the installation of drain tiles.

Overall, the goal of addressing a wet basement or a basement flood in Toronto is to minimize water damage and create a safer, more habitable space within the building.
