Keeping Your New Basement Dry.

Having TUFF-N-DRI® Basement Waterproofing System installed is a vital step to protecting your new basement against foundation wall leaks, seepage and interior condensation. But no waterproofing product works in a vacuum – it interacts with the soil surrounding your foundation and the construction of your basement walls. Here are some helpful tips about additional measures you can take to protect your basement from excess moisture:

Outside the Basement

Working Drain Tile – A drainage system is installed with TUFF-N-DRI and must always remain functioning. The drainage system should empty by “gravity feed to daylight” or to a sump basket where water is pumped out. If your drainage system goes to daylight, make sure the tile opening has not been covered by dirt, thereby blocking the water flow. You might also consider adding a wire mesh cover to the opening to stop animals from nesting in the tile. If your drainage system empties to a sump pit, make sure the pump is activated before the water level reaches the level of the drain tile. If you are in a high water table area, you may want the added assurance of a battery-powered emergency backup pump.

Proper Soil Slope – Make sure that soil slopes away from basement walls. The grade should slope downward and away from the wall at least 5% (about 6 inches) over the first 10 feet surrounding the foundation wall. Also, downspouts should direct water away from the foundation.

Grade Line Height – Don’t allow the grade line of your yard or landscaping to extend above the height of TUFF-N-DRI. A waterproofing system can stop water from penetrating only where it is applied.

Inside the Basement

Construction Moisture – During installation of a poured wall basement and floor slab, roughly 400 gallons of water is present in the concrete. In block construction, the floor slab will have roughly 200 gallons of water. This water will escape into your basement space in the form of humidity. To help relieve your new basement of this excess water vapor, circulate air into and around the basement and run a dehumidifier for several weeks.

Internal Moisture – Take these precautions to minimize ongoing basement moisture that can originate inside your home:

  • Make sure plumbing remains leak-free
  • Keep the door(s) leading to the basement closed
  • Dehumidify the air (chemically or mechanically and>
