A wet basement can turn into a big problem for your home. Maybe you've been struggling with a wet basement for years, or maybe the problem has started suddenly. Either way, there's a solution that can help. A contractor can choose between interior and exterior waterproofing methods. An exterior method is often chosen because it keeps water from getting in your basement. Here's a look at how to waterproof your basement from the exterior of your home.
Check The Simple Things First
If your problem with a wet basement has developed recently, then consider if you've made changes that affect water drainage around your home. If you've installed landscaping near your house, water might be blocked from draining away. Also, if your gutters are bad, they may be dumping water near your foundation. These two problems have simple solutions that you can do yourself. Simply fix your gutters and change the landscaping so the ground slopes away from your house.
Hire A Waterproofing Contractor
Unfortunately, wet basement problems are often more difficult to fix than just having new gutter troughs put on. If water is seeping through the concrete due to hydrostatic pressure of water in the soil, then waterproofing the exterior walls could be a good solution that will block water so your basement dries out. First, the walls have to be exposed, and this entails digging the soil up around your house so the contractor can work on the walls. Then, a waterproof barrier or coating is applied to the walls. With the barrier in place, water won't be able to leak through the concrete and your basement will stay dry.
Another method that's often used for exterior waterproofing is to install a French drain. Your contractor may discuss this option with you too. When your yard is dug up to waterproof the exterior walls, that could be a good time to put in a drain as extra protection against water. With the drain in place, water that flows toward your house or that rolls down the waterproof barrier will fall into a drain and flow away from your home.
The good thing about exterior waterproofing is that you don't have to rely on a sump pump to keep your basement dry. If the pump fails during a storm, your basement could get wet if you rely solely on interior waterproofing. When a waterproofing method is applied to the outside, then water is blocked from entering. If you're going to finish your basement or if you just want it dry to get rid of the musty odor, then talk to your contractor about the best way to waterproof the walls so the risk of basement flooding is kept to a minimum in the future.
