Do Your Basement Walls Look Like This?

Why do I have efflorescence?

The white chalky powder on your basement walls, also known as efflorescence, needs three things in order to appear on your basement walls:

Salts: Basement walls are generally made with a variety of brick containing limestone clay or sand. These items are full of natural minerals that contain salt. The salt is dissolved by water in your basement walls.

A Water Source: Water can build up outside your foundation resulting in hydrostatic pressure. This pressure then pushes that moisture into your basement.

Entry Point: The water must be able to enter the basement - whether that be through the floor, wall cracks or the pores in the concrete.

If you have efflorescence on your basement walls, you have a moisture problem in your basement. If that problem is not addressed, it can make your foundation walls crack and even cause your basement to flood.

How can I stop efflorescence?

If you have efflorescence on your basement walls, you have a moisture problem in your basement. If that problem is not a ddressed, it can make your foundation walls crack and even cause your basement to flood.
