Basement flooding can be a complete disaster. Any amount of water that seeps into your foundation or basement can cause damage. It can make your walls warp or buckle, and it can compromise the structural integrity of your foundation, causing it to shift. Interior waterproofing can stop water before it reaches the inside of your basement, but the water can still weaken the outside of your walls and cause them to rot or mold. Exterior waterproofing keeps water out of your home entirely. Here are four facts every homeowner needs to know about exterior waterproofing.
It's best to do it while building your home.
If you're having your home constructed on an empty plot of land, you should plan to waterproof your house's exterior. Erecting waterproof barriers during construction is ideal because the earth around the foundations hasn't been set yet. In order to lay down waterproofing material, your contractor will need to expose the foundation of your house. You won't need to deal with reconstructing the landscape if this is done before the yard and house are finished.
Exterior waterproofing membranes protect your home.
A waterproofing membrane is the best way to keep water out of your basement and foundation. The membrane is usually made of absorbent clay and thin plastic. Together, these materials repel water, keeping your home safe from the outside.
A drain can be installed.
Exterior waterproofing can keep the water from entering your home, but large amounts of standing water can still create a problem. This is where a drain comes in. A French drain system will allow water to flow away from the base of your house, where it will be ejected through a drain. Proper drainage reduces the stress placed on your waterproofing membrane. If you have a drain installed, remember that you need to maintain it. Clear away rocks, leaves, and other debris that get caught in it so your drain pipes do not get clogged.
A downspout line can help.
Your roof's gutter directs water off your roof down into the soil at the base of your house. However, areas with heavy rain can easily overwhelm the soil. When too much water is ejected right at the side of your house, your foundation could be in jeopardy. Fortunately, a contractor can easily attach a downspout line to your gutter to extend its reach. Redirect the water from your roof to a more optimal area with one of these devices.
