Protect Your Home with Sub-Slab Basement Waterproofing


Basement waterproofing is a crucial consideration for homeowners, and one of the best and most cost effective methods is sub-slab waterproofing. According to the University of Minnesota Extension, sub-slab systems play an essential role in preventing moisture intrusion and mold growth, both of which can compromise your home’s structural integrity and your family’s health. As an added bonus, the sub-slab system is less expensive to install than other systems.

The Significance of Sub-Slab Basement Waterproofing

Moisture intrusion can wreak havoc on your basement, leading to mold growth, structural damage, and even health issues. Sub-slab waterproofing safely and effectively moves water away from your foundation, protecting your home from these potential problems. Installing a sub-slab system can help you avoid costly repairs and maintain a healthy living environment.

Types Waterproofing Systems

When it comes to waterproofing, there are several solutions to consider along with sub-slab systems.

Exterior Systems

Membrane Systems

  • Benefits: Highly effective in preventing moisture intrusion.
  • Drawbacks: Can be complex and costly to install and requires the excavation of the ground around the basement and may require removing sidewalks and decks along with landscaping.

Drainage Systems

  • Benefits: Redirects water away from the foundation.
  • Drawbacks: Requires regular maintenance to remain effective. Requires the excavation of the ground around the basement and may require removing sidewalks and decks along with landscaping.

Interior Systems

Drainage Channels Installed On Top Of The Concrete Floor

  • Benefits: Less invasive installation process.
  • Drawbacks: Not as effective as exterior systems. Since the floor is level, the water tends to pool in the channels and does not move efficiently toward the sump basin where the sump pump can move it away from the foundation.

Drainage Channels Installed On The Basement Footing 

  • Benefits: Somewhat less invasive installation process.
  • Drawbacks: May not be as effective as exterior systems. Since the footing is level, the water tends to pool in the channels and does not move efficiently toward the sump basin where the sump pump can move it away from the foundation.

Sub-slab Basement Waterproofing Systems

  • Benefits: Highly effective at keeping basements dry, Less expensive and less invasive than exterior systems.
  • Drawbacks: Requires the removal of concrete about 18” from the wall around the perimeter of the basement and the removal of dirt and debris to create a trench that slopes properly to the sump basin where the sump pump will move the collected water away from the foundation.
