Introduction: Water in Basements

The purpose of basement waterproofing is to prevent water from entering the basement. Water can enter the basement through cracks in the foundation wall, windows, or doors. Basement waterproofing can also prevent water from seeping into the basement, at the cove joint, where the wall meets the floor, due to hydrostatic pressure.

There are several methods of basement waterproofing, including exterior waterproofing, interior waterproofing, and subgrade systems or French drains. Exterior waterproofing involves installing an impermeable membrane on the outside foundation wall and footer. Interior waterproofing involves sealing cracks and holes in the basement walls and floor. French drains are installed around the inside perimeter of the foundation to collect and channel water to the sump basin to allow the sump pump to discharge the collected water.

The Causes of Basement Flooding

There are several possible causes of basement flooding. One is that the exterior foundation walls are not properly waterproofed. This can allow water to seep in through cracks and holes, causing the basement to become wet. Another possibility is that the gutters and downspouts are not functioning properly, causing rainwater to overflow and pool around the foundation of the house. This can lead to water seeping into the basement through cracks and gaps and at the cove joint, where the wall meets the floor. Silted, clogged with mud and sand, or improperly installed subgrade drainage systems will also cause a basement to flood.  Sump pump failures due to age or a power failure are another reason why a basement will flood. 

The Effects of Basement Flooding

A basement is the lowest level of a home and is often prone to flooding. Basement flooding can cause extensive damage to your home and can be very costly to repair.

A flooded basement can lead to mold growth, as well as structural damage to your home. If you have a finished basement, flood waters can ruin carpeting, drywall, and furniture. Even if your basement is unfinished, flood waters can damage flooring and support beams. Any stored belongings will also be destroyed or damaged when the basement floods.

To prevent basement flooding, you should consider waterproofing your home. Waterproofing your basement will help to keep water out, and can prevent extensive damage to your home and belongings.
