There are a few different strategies you can use to effectively drain water away from your house foundation:
Grade your property: Make sure the ground around your house slopes away from the foundation. This will help water flow away from the foundation rather than towards it.
Install gutters and downspouts: Gutters and downspouts can help collect rainwater from the roof and redirect it away from the foundation. Make sure the downspouts are extended far enough away from the foundation to prevent water from pooling near the base of the house.
Install a French drain: A French drain is a trench filled with gravel or a perforated pipe that redirects water away from an area. You can install a French drain around the perimeter of your house to help divert water away from the foundation.
Repair any cracks in the foundation: If there are cracks in your foundation, water can seep through and cause damage. Repairing any cracks as soon as possible can help prevent water from entering the foundation.
Use a sump pump: If your property is prone to standing water, you may want to consider installing a sump pump. A sump pump is a device that pumps water away from the foundation when the water level gets too high.
Full perimeter waterproofing: Excavation of foundation around the exterior of the building. Inspect and repair the concrete. Waterproof with foundation emulsion and dimpled membrane. Allow the concrete to breathe so it cures and reaches its full structural integrity.
Smaller sections of waterproofing are also effective. Be sure to backfill with drainage stone so water does not gather against the foundation.
By following these steps, you can effectively drain water away from your house foundation and protect your home from water damage. It is also recommended to insulate the exterior of the foundation to grade before backfill.
