When water enters into your home's basement through the foundation or walls, it can cause water damage and mold and mildew growth leading to health problems in you and your family. Here are two methods to help you collect and divert water from your basement to keep its interior dry.
Install an Exterior French Drain
Installing an exterior French drain around the perimeter of your home is a great way to collect any excess ground water around your home's foundation to divert it away from your home. Look at the slope of the soil around the exterior of your home and determine which way the soil slopes downward toward your home, as this can indicate which sides of your home will receive a flow of ground water and cause moisture intrusion into your home. If the soil slopes toward three sides of your home, for example, you only need to install an exterior drainage system on these exterior sides of your home. Even if there is not excess precipitation in your area to saturate the soil around your home, nearby bodies of water and a high water table can all contribute to moisture leaking into your basement or foundation.
If you have any landscaping around your home that will be disturbed, relocate it into planting pots or to other areas of your yard until your drain system is installed. It is recommended to excavate the soil around your foundation down to the foundation footers of your home to create the trench for the drainage system. This allows the drainage system catch moisture at this level to drain into the drain pipe, and prevent it from entering your home's basement and foundation walls.
Depending on the depth of your foundation, you can hire an excavator to remove the soil, or you can rent a gas-powered trencher to dig the trench to the appropriate depth. Make sure the trench is wide enough to allow you to install the drainage system and surrounding gravel. First, install a layer of landscape fabric on the bottom of the trench to keep soil from clogging your drain pipe. Place the pipe in the trench's base and cover it with several inches of gravel. Then, wrap the landscape fabric over the top of the gravel and replace the soil into the trench.
As you replace the soil around your home's foundation, use it to build a slope away from your home's foundation. This will provide extra slope to help water runoff away from home to further keep your basement dry. It is recommended to create a slope of at least six inches over the first ten feet of soil around your home. This diverts water that may fall from your home's roof during wet weather.
Install an Interior Drainage System
When you don't want to dig up your landscaping around the exterior of your home, you can always install a drainage system inside your basement. This drainage system captures ground water that enters into your basement through the walls of foundation to collect it and pump it out of your home with a sump pump. If your basement has a concrete floor, you will need to remove part of the flooring to excavate the trench for the drainage pipe.
Use a circular saw with a masonry blade to make a cut into the concrete of the floor so you can remove at least 12 inches of the flooring around the perimeter of the room to dig the trench. Then, you can use a shovel or rent an electric trencher to remove the soil in the trench. You will need to remove enough soil in the trench to place the drainage pipe and a few inches of gravel to help its drainage. Choose a position in the trench where you will install your sump pump and excavate any additional soil to provide space for the sump pump to fit within the ground.
Layer some gravel into the trench, then set the French drain into the trench, covering it with gravel. You can also install a flooring grate over the top of the gravel and the pipe beneath it to keep the gravel in place inside your basement floor. Be sure you connect a drainage pipe to the sump pump to the outside to your house. You can extend the pipe up your basement wall and to an outside opening. Then, make sure the pipe extends several feet away from your home's foundation to safely drain any collected water. For more information, contact companies like Rite-Way Waterproofing.Share
