Your foundation is probably the most important element of your home. After all, without it, there would be nothing for the home to stand on. It's like the Bible story that talks about the wise man building his house on the rock. Your foundation is your rock, and you need to make sure that it stays in top shape for as long as you own your home. Unfortunately, tiny cracks and holes in the foundation are constantly being forced bigger as water-laden soil presses against the walls. Water soaks into the concrete or stone that your home rests upon and seriously undermines its integrity. That's why foundation wall waterproofing is so vitally important to the continued well-being of your home.
There are two common components of waterproofing the outside of your foundation. One is to move as much water as possible away from the foundation. The usual method is to dig a trench around the foundation and install drain pipe. If you're lucky, the trench you dig may only have to be a foot deep, but it isn't uncommon to have to go as deep as three feet in order to make the drainage system effective. Once the tiling is put into place, make sure that the backfill of soil you place on top is inclined away from your home so that water will run away from the foundation.
The second part of waterproofing the exterior of a basement wall is called parging. This means that you will use some type of waterproofing material to put a half inch barrier between the walls and the soil. Following the parging step you will want to coat the entire foundation with epoxy to make sure that the waterproofing will stay put and that water cannot seep through. You want to do these coatings while you have the trench dug for your pipe, because that's when you'll be able to do the job most easily.
Waterproofing compounds can be used on the inside of walls, too, which can help ensure that no water can escape through them to damage your basement. Small crack repairs can be done using a patching product, or you can paint the walls entirely with waterproofing paint. By making these extra efforts at foundation wall waterproofing, you can maintain the integrity of your foundation as well as the resale value of your house.
