Our Top 5 Best Foundation Drainage Systems

While there are different ways to address water pooling around your foundation, here are our top 5:

1. Exterior Drainage

Most homes are built with exterior footing drains that move water from the soil away from your foundation, preventing hydrostatic pressure and basement leaks.

As long as the drains are properly functioning, your home is secure. However, drains will break down over time and inevitably fail. Buried in a trench, the surrounding soil can crush and clog them.

While they are a building requirement, it’s important to install additional solutions to shore up your home’s defenses.

2. Gutters and Downspouts

Gutters and properly installed downspouts are another crucial step in preventing foundation damage.

Roof gutters stop rainwater from spilling down from your roof, while downspouts channel that water away from your foundation

These systems also rely on properly grading your yard, which happens to be our next point.

3. Yard Grading

Over time, the dirt around your home’s foundation tends to harden and settle, and two things happen that can hurt your home:

  • Your yard may begin to slope back towards your home (what’s called “negative grade”). This results in the water your downspouts are trying send away from your foundation comes trickling back towards it.
  • You may discover dips or depressions where your foundation meets the soil where water is slowly (or not so slowly) eroding the support around it.

Either way, water always takes the path of least resistance. It will flow to the lowest-lying area and form puddles around your foundation.

To prevent this, call a trusted local landscaping expert to help get your yard back to “positive grade” that, at minimum declines 6 inches for every 10 feet away from the foundation.

While landscapers can also build up any dips and depressions in your yard, you can probably do this step yourself and save a little on foundation repair costs. Just do the following:

  • Add soil to the dip (avoid using sand or mulch, as they can hold more water and don’t compress well).
  • Take care to compact the soil thoroughly.
  • Leave a gap of at least 4 inches between the siding and the soil to prevent siding rot and deny termites and ants an easy access point into your home.

4. Curtain Drains

Negative grade is one thing, but if your home is located at the bottom of a hill, you face a different challenge entirely when you try to direct water away from the foundation. In your case, curtain drains are key.

Install curtain drains along the edge of the incline to intercept and divert the flow of water away from your home.

Installation is best left to the pros, since positioning is really, really important. The process involves digging a trench near the home’s foundation and laying a perforated pipe within it. The pipe is then covered with gravel or stone, and the area is filled in, creating a visible stripe of stone along your yard.

Curtain drains aren’t usually a standalone solution because they can usually only stop water from coming at your home from a single direction. They should be combined with other drainage measures for optimal effectiveness.

5. Interior Drainage Systems (The Best Option)

Interior drainage systems are the most effective way to protect your foundation from water damage. Even if you don’t have exterior drainage, curtain drains, or positive grading, interior drainage protects your foundation from the inside out.

If you have a basement, then BasementGutter™ is a great place to start. If your house sits on a crawl space, then perimeter drains and matting are the right move.

These foundation drainage systems collect water that gets into your foundation and direct it toward a sump pump. The sump pump moves that water out and away from your home where it can’t damage anything.

Interior drainage systems are comprehensive solutions for mitigating water damage and protecting your home’s foundation. Coupled with a wall vapor barrier and a dehumidifier, your foundation won’t have to reckon with the forces of nature—the forces of nature will have to reckon with your foundation.
