Prevent foundation damage and lawn issues with these effective drainage tips
Download Article
When inclement weather results in excess water collecting around your home, it's essential to have adequate drainage to prevent damage to your property. Draining water away from your home begins with a sound gutter system to carry water away from your home's foundation. However, other tips include adding extension downspouts or a rain barrel to keep your yard and home dry all year round. Refer to this guide to learn more tips on diverting water!
Easy Tips for Water Drainage Problems
- Regularly clean your home's gutter systems to remove debris.
- Attach extension pipes to your downspouts to direct water away from your home's foundation.
- Add extra compact soil near your foundation to create a gentle, 2–3 feet (0.61–0.91 m) slope that leads water away.

Maintain your gutter systems with regular cleanings twice per year. Gutters collect rainwater from your home's roof and deposit it onto the ground. Most residential gutters are made from aluminum with a downward slope of 1 ⁄ 2 inch (1.3 cm) towards the downspout for every 10 feet (3.0 m). Leaves, needles, and other debris can clog the system, so wear rubber gloves to clean the muck out by hand. Inspect gutters at least twice per year and after big rainstorms. [1] X Research source
- Follow up the debris removal with good water flushing from your garden hose. Ensure the water flows freely from the downspouts, and remove any blockages that may prevent this.
- If you prefer, you can hire a professional to clean your gutters . The charge for this service varies, depending on the size of your home, but usually ranges from $50 to $250.
-
Install downspout extensions . Downspouts are the parts of the gutter that run vertically from the roof gutter to the ground. To extend them, attach an elbow to the end of the downspout and then connect an extension piece. The extension piece will be several feet of straight pipe that can be screwed on. [2] X Research source
- Make sure to direct water at least 6 feet (1.8 m) away from your home’s foundation.
- If necessary, connect the downspouts to a PVC pipe and bury the pipe underground to direct the water further from your home.
- Avoid pointing the downspout extensions towards your driveway, as water runoff can freeze your driveway during the winter.

Properly grade the ground around your home. Overflowing gutters and inefficient downspouts can erode the ground surrounding your home. This erosion can create a trench in the soil that traps water there. If you see any gaps like this, fill them in with soil. Add more than you need to create a gentle slope 2–3 feet (0.61–0.91 m) that will lead the water away from the house. [3] X Research source
- Avoid soils with high clay content since these drain poorly. Purchase granular soil with a high sand content.
- Buy one bag to start the job. Once you know how much area 1 bag covers, you'll have a good idea of how many more you'll need to finish the job based on the size of your home.
- Pack soil around your house and slope it downwards at about 1 inch (2.5 cm) per 1 foot (0.30 m).
- Be sure to pack the soil firmly when creating the slope. Then, add grass seed, which, once it takes root, will prevent the soil from eroding.

Dig a trench for a French drain. A French drain is a trench filled with gravel and a perforated pipe to redirect water from an area. [4] X Expert Source David Balkan
Professional Plumber & CEO of Balkan Sewer & Water Main Expert Interview. 30 March 2021. Begin digging a 4–6 feet (1.2–1.8 m) hole with a shovel surrounding the foundation of your home. Make the trench about 6 inches (15 cm) wide and about 24 inches (61 cm) deep. The trench should extend to the lowest part of your yard. [5] X Research source- Add a layer of gravel 1–2 inches (2.5–5.1 cm) thick on top of the compacted soil.
- Install piping with two rows of perforated holes running down its length. Wrap them in landscaping fabric and lay them towards the earth to prevent the holes from getting plugged.
- Fill the trench with gravel within 1 inch (2.5 cm) of the surface. Cover the remaining 1 inch (2.5 cm) with a piece of sod to disguise the trench. [6] X Research source
-
Build a rain barrel for your backyard. Take a 55-gallon barrel and place it beneath your gutters' downspout or where water accumulates the most. Use a power drill to make a 5-inch hole above the base of the barrel and another hole 3 inches from the top for overflow. Attach a spigot to both holes. Cut or drill another hole large enough for the downspout to fit into. [7] X Research source
- Rain barrels collect water runoff that can then be used to water your lawn or garden, wash your car and outdoor items, or flush a toilet.
-
Create a rain garden that absorbs excess gutter water. An attractive way to divert water is with a rain garden, which absorbs runoff to reduce flooding. Choose a spot at least 10 feet (120 in) from the house and 50 feet (600 in) from a septic system. Remove the grass with a sod cutter or sharp spade. Use a shovel and dig at least 6 feet (72 in) deep. Dig a trench for a pipe that can carry water from one downspout to the rain garden and fill it with gravel, like a French drain. [8] X Research source
- Fill the area with rain-garden soil. Group plants in zones. For instance, place plants that thrive in wet environments in the center. For plants that thrive in standing water, place these at the edges.
-
Install a sump pump for basement flooding. If your basement is prone to floods during a storm, locate the lowest point and dig a hole deep enough to accommodate a sump pump . Add 2 inches (5.1 cm) of gravel to the bottom of the hole, then place the pump into the hole. Run a flexible hose through the basement wall to remove excess water. Apply a layer of concrete to conceal the hole surrounding the pump. [9] X Research source
- Use a hole saw to drill through the basement wall. Run the pipe through and caulk the edges to fill in any gaps.
- A sump pump has a float valve that rises when the water level does; this is what activates the pump.
-
Seal coat your driveway as a preventative measure. Water can seep into cracks in your driveway and expand or contract due to fluctuating temperatures. Over time, this can create water drainage issues. Squeeze or pour in crack sealer to fill 1 ⁄ 4 inch (0.64 cm) cracks or larger. Then, cut in the borders of your driveway using a 4-inch paintbrush . Apply two coats of driveway sealant with a squeegee. [10] X Research source
- If you have potholes in your driveway, use an asphalt repair mix to fill them.

Common Causes of Drainage Issues

-
Insufficient grading Grading refers to correcting the slope of your yard so rainwater flows away from the foundation of your home. Generally, a yard’s grading should be between 3% to 25%. Anything less can create drainage issues while grading more than 25% can create erosion issues. [11] X Research source
-
Poor soil drainage If your soil doesn't drain properly, it can become waterlogged and inefficient at drying properly. To prevent this, use organic matter, like composting, to improve the soil's drainage quality. [12] X Research source
-
Debris in gutters and downspouts A common cause of drainage issues is an over-clogged gutter. These systems can be easily filled with debris after a storm, so cleaning them before or after a storm can benefit your property.
-
Faulty drainage systems If your gutters or downspouts weren't installed properly, it can prevent water from flowing away from your house correctly. Inspect your drainage system for any blockages, cracks, or gaps affecting its performance.

Signs of Water Drainage Problems
Download Article
-
Structural damage A home's foundation withstands natural forces to keep your home standing. However, the more water collects around the foundation over time, the more pressure it puts on it. You may notice cracks in the walls, warped floors, or even mold or mildew growth in the basement.
- Foundation damage is a costly repair problem ranging between $2,000 to $8,000. [13] X Research source
- A common sign of structural damage is leaks in the basement. Look out for where water can seep through the windows and cracks.
-
Pooling or standing water As much as you may love to stomp in a puddle of water on the street, it's not so fun it's in your backyard. You may find puddles around the house or scattered around the yard. Standing water can attract mosquitoes and other pests and create an eyesore.
-
Soggy lawn The more water accumulates, the harder it is to dry, leading to soggy grounds that can negatively affect grass and plant growth. Similarly, it'll leave your backyard feeling more like a mud pit than an oasis for relaxation.

QuestionWhy are the holes in the pipe facing down? Wouldn't you want them facing up to catch the water?Community AnswerThe holes must face downward so that underground water can enter the discharge pipe. Remember, the bulk of the water above ground will enter through the downspout. If the holes are facing upward, water carrying sediment and other debris will eventually clog the perforated holes and the drain will not function correctly.
-
QuestionCan putting a rain gutter along the porch edge stop water from collecting on the porch?Community AnswerPossibly. If the gutter has a drain that leads off the porch or away from the porch, it should not be an issue. However, gutters are meant to catch water coming off your roof. Rain could still end up on your porch depending on how hard it is raining or the direction of the wind.
-
QuestionWhy wouldn't I lay the french drain right up against the foundation? Why 4 - 6 ft away?Community AnswerYou don't want any water going back against the house, since this drains through most of the pipe. IT would add more water to the sump pump and seep into the basement or crawlspace.

Tips
- If you don't have a good place to route the downspouts, you can utilize a dry well. A dry well is a large, perforated plastic drum that can be buried in the ground and surrounded by gravel. Route the downspout lines directly into the dry well to keep water from building up on your neighbor's property or flowing into a storm drain.Thanks
