If the floor of your basement gets wet every time it rains, then exterior waterproofing could be the solution you need to keep your basement dry. An exterior method is ideal because it prevents water from reaching your foundation. Exterior waterproofing can be done in a few ways, and sometimes the methods are even combined. Here's a look at what exterior waterproofing entails.
An Exterior Drain Catches And Diverts Water
One method for exterior waterproofing is to install an underground drain pipe near your home. This pipe is different from a usual plumbing pipe because it has slots in the top that allow water to fall into it. When water flows toward your house, it falls into the drain before it reaches your foundation. Once the water is in the pipe, it drains out to the street or some other area that is away from your house and basement.
It's necessary to dig a trench in your yard to house the pipe. The trench is prepared with gravel and landscaping fabric so water can drain into the pipe but roots stay out. Once the drain is installed, it is covered with soil and grass so it is invisible. The only part that might be seen is the end where it empties into the street.
One advantage of this type of exterior waterproofing method is that it relies on gravity to work. There is usually no need for a sump pump that could possibly fail and cause your basement to flood.
A Waterproof Wall Coating Blocks Water From Seeping Inside
Another form of exterior waterproofing your contractor may suggest is to apply a coating or membrane on the exterior wall. This can be done at the same time you have the drain put in the ground since dirt needs to be dug away from the exterior walls to apply the coating. Some waterproof coatings are painted on and others are membranes that are attached. These block water from seeping through the concrete walls. The membranes have grooves in them that direct water to the drain so water is diverted from your home every time it rains.
Before your contractor recommends the best way to waterproof your home, he or she will figure out why water is leaking into your basement. It might be necessary to fill cracks or take additional measures to keep your basement nice and dry. Exterior waterproofing keeps water from reaching your home, so you'll have peace of mind your basement will stay dry when it rains. If you plan to turn your basement into a bedroom or family room, you definitely want a waterproofing method you can rely on to protect your electronics and furniture.
