TUFF-N-DRI® Basement Waterproofing System is a reliable defense against three main sources of basement moisture – foundation wall leaks, seepage and interior condensation. By minimizing excess moisture in your basement, you can maximize the advantages your lower level space provides:
Damp basement space may create an uncomfortable living environment. As more water evaporates into the air, it can also heighten the chilly feeling of colder seasons and the hot, sticky feeling of warmer seasons. Dry basement space avoids these conditions to enhance the comfort and enjoyment of lower level living.
Greater humidity in your home can make air conditioners, heaters and dehumidifiers work harder and demand more energy. So the moisture control of TUFF-N-DRI can help reduce your home's energy requirements. In addition, WARM-N-DRI® Foundation Board (part of the TUFF-N-DRI system) provides insulating values up to R-10 to further protect against energy loss.
The structural materials of your home as well as the furnishings inside will benefit from ongoing moisture protection. Prolonged exposure to excess moisture can crack concrete, corrode metal and cause wood to warp, rot or swell. Fabrics that compose your carpeting and upholstery also may rot or stain from too much moisture. And excess humidity and condensation can affect sensitive electronic components in computers, video and audio systems. So the premium moisture control of TUFF-N-DRI not only protects your basement space – it helps guard the value of furnishings inside.
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.
Below are some helpful tips about additional measures you can take to protect your basement from excess moisture:
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.
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.
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.
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.
Take these precautions to minimize ongoing basement moisture that can originate inside your home:
TUFF-N-DRI® Basement Waterproofing System and some simple preventive measures can help reduce moisture inside your basement. In addition, the following actions are recommended by numerous government, health and environmental agencies for reducing excess moisture throughout the house.
