Basement Wall Sweating

Basement wall sweating. Basement wall sweating could be one of two things:

  1. Condensation. Condensation is what occurs when moisture from the concrete hits the air in your basement. Condensation looks like droplets of water sitting on the concrete.
  2. Seepage. Seepage is what occurs when water is pushed from the soil surrounding your basement through the concrete and into the basement. Seepage looks like you spilled a bucket of water all over your basement wall.

How To Stop Basement Wall Sweating

There are a few ways to stop basement walls from sweating. If you have water coming in through the concrete from the surrounding soil you want to apply 2-3 coats of the Armor S2000 concrete sealer. Through densification the sealer will stop the penetration of water and significantly reduce the penetration of moisture through the concrete. If the walls are concrete block or cinderblock, consider 1-2 coats of the Armor S2000 and 2 coats of the Armor SX5000.

If the exterior of the basement is exposed (and not back-filled with dirt), you can seal the exterior of the foundation with the Armor SX5000 which will stop 99% of water and moisture absorption through the concrete, block or cinderblock. The combination of sealing the interior and exterior will stop absorption and penetration at the source.

    Very happy with the results of the Armor L3000. My dehumidifier had to be emptied every couple of hours, the humidity in my basement was very high. I used your sealer and I no longer have the dehumidifier plugged in. Thanks for the suggestion Tanya!!!!
