My Basement Leaks When It Rains! What Should I Do?

If your basement leaks when it rains, you still have time to fix it before it gets worse.

The first step in fixing the leakage problem is pinpointing where exactly the issue is coming from.

Below you will find the most common causes of basement leaks when it rains as well as what you need to do to get them fixed.

Fix Your Wet Basement

Symptoms You May Face After It Rains

Damp floor – Damp floors are a common symptom that homeowners notice after it rains.

Wet carpet – A wet basement carpet after it rains generally means there is an issue underneath that is causing water to come through the basement floor or between the floor and wall.

Standing water – Obviously, if you have standing water after it rains, it means there is an issue that needs to be taken care of beneath the surface.

Mold accumulation – Mold can grow in your basement in less than a week after it floods. Be sure to check the walls and floors as well as around pipes and sinks.

Where Does Water Come In Through?

Walls – Water can come through basement walls after it rains because the soil that is surrounding the walls applies pressure on the wall, and water eventually makes it way into the basement. The grading of the ground surrounding your basement could also be the perpetrator if it slants towards your house as opposed to slanting downwards so that the water runs off away from the house. Your walls may also have cracks in them. This can be caused by a poor foundation which causes the walls to move, and in return, crack and allow water to seep through.

Floor – If your floor is damp, leaking, or has standing water after it rains, there could be a multitude of issues that are causing these issues. One issue that you could be facing is an unsound foundation. When the foundation is not secure, movements can cause cracks in the floor, which leads to water coming through, especially after rainy days or seasons. If you have a drainage system that is backed up or clogged, this could also lead to water coming through your basement floors. Rain will fill the soil around the house, and when it has nowhere to go but into the house, that is where it will end up.

Cove joint – Your cove joint is the place where your basement floor meets the wall. After it rains, water can seep through the cove joint through hydrostatic pressure. Water builds up and rises underneath the basement, and it has nowhere else to go but through the cove joint. As tempting as it may be to seal the area, it probably will not fix the problem, and the issue will arise again in the future once the water makes its way to another part of your basement. The most common cause of the rise in water is an underperforming drainage system.

Solutions to Fix Basement Leakage When It Rains

Install or repair a drainage system – The recommended solution to wet basements is a proper drainage system. This can be a drain tile system, which is a common and powerful system that is designed to catch water before it makes its way into your home. It relieves the hydrostatic water pressure, and keeps the water out of your living space. The baseboard system is also a brilliant system that takes care of smaller leakage issues, and it does not require any breaking or replacement of your concrete floors.

Foundation repair – If foundation failure is the culprit in your leaky basement issue, it’s a good idea to stabilize it before the foundation becomes less secure. Foundation failure is commonly caused by poor landscaping and gutter systems, and the solution is a piering and stabilization system.

Sump pump installation – Sump pumps collect water through a barrel and then remove the water, so it doesn’t leak into your basement. If your sump pump is damaged, clogged, or not working, it may need to be replaced and reinstalled.

Can It Get Worse If I Don’t Take Action?

Unfortunately, yes, the issue can compound if action is not taken now. Depending on the problem you face, cracks in your floor or walls can increase in size. Your foundation can continue to become less secure. The more it moves, the better chance water will have to seep into the basement. 

Drainage systems will not fix themselves, and generally don’t get better over time. The water may leave your home after some time, but the flooding could come back once another hard rainfall hits.

What to Do With Cracks in My Basement Floor

Have cracks in your basement floor?

Learn what you need to do to fix them and stop them from occurring in the future.

What Causes Cracks in Basement Floors?

Cracks in basement floors can be caused by a multitude of issues. They commonly have to do with either the moisture or water underneath the basement floor or a subpar foundation system that needs stabilization. Not all cracks in basement floors require fixing, but some can lead to or be a sign of larger underlying issues in your home or your building’s structure and foundation.

Types of Cracks in Basement Floors and Fixes for Them

Sometimes basement floors in old houses dry up and result in cracks. Cracks can also appear in newer houses.

It’s very important to identify the problem correctly, as a misdiagnosis could result in further damage in the future.

Here are the main types and causes of basement floor cracks:

1. Hairline cracks

Hairline cracks are smaller cracks in basement floors that have not opened and do not affect the structural integrity of your home.

Cause: Hairline cracks can be caused by changes in the temperature of the air and concrete, poor workmanship on the builder’s part, the type of chemicals mixtures used, relative humidity, and several other factors.

Fix: Hairline cracks don’t necessarily need immediate attention, but it’s good to keep an eye on them in case they open up into larger cracks. To fix hairline cracks, you will first need to clean the crack, apply a sealant, and then cure it to harden the sealant.

2. Heaving

When basement floors rise up, it is called “heaving”, and this can cause damage to your home.

Cause: Heaving usually occurs when the ground beneath expands and causes the basement floor slab and footings to rise up with it. When the basement floor rises, it can cause cracks which are destructive to your home.

Fix: Since heaving is oftentimes caused by unwanted water accumulation, the way to begin fixing this problem is by getting rid of that unwanted water. It can accumulate through improper drainage, evaporation, poor soil conditions, or transpiration. After identifying where the water is coming from, you can then put a system in place to keep the water out and maintain a stable foundation.

3. Foundation settlement

Foundation settlement occurs when the compression in your foundation is unequal. This can cause lots of repercussions, but one of these is cracks in your basement floor.

Cause: Foundation settlement is often caused by changes in the soil around a home or building. The soil that once supported the structure changes, and that can cause cracks in basement floors.

Fix: Basement Water Controlled uses a Stabil-Loc foundation piering system to fix foundation settlement issues. It’s important to place the anchors in the system properly and securely in order to safely secure and stabilize the foundation. 

4. Water seepage

Water can seep in through the cracks of your basement floor.

Cause: Water comes in through large and small cracks of your basement floor. The soil and ground underneath your basement is filled with moisture, and at different times of the year and, depending on water levels, it can lead to water seepage through cracks in the floor.

Fix: Smaller cracks do not always need to be fixed, but if water is leaking, it could be evidence that you need to update your drainage system. Larger cracks may be evidence of structural issues. In this case, it’s best to get it looked at by a professional.

Should I Fix the Basement Floor Cracks Myself or Hire a Professional?

You may think smaller cracks in your basement floor will be easy fixes, but that’s not always the case. Small cracks can get larger over time if not treated.

As a rule of thumb, anything larger than ⅛” should be sealed, and anything larger than ½” should be leveled.

Below are the most commonly asked questions about cracks in basement floors.


Q: Are cracks in concrete floors normal?

A: Cracks in concrete floors are not uncommon. They commonly occur because of changes in moisture and water in the ground beneath the foundation. Small cracks that are not “open” do not require fixing, but larger cracks and water seepage may be a sign of a bigger issue.

Q: What do cracks in the basement floor mean?

A: Cracks in the basement floor can tell lots of different stories. Sometimes the conditions in which the concrete floor was poured can cause smaller cracks, which do not affect the structural integrity of the home or builder. Larger cracks can mean that your foundation is not equally compressed or that the soil underneath the home or building is full of moisture and needs drainage work done.

Q: When should I be concerned about cracks in my basement floor?

A: Small cracks that have not opened do not require fixing. However, if the cracks are open, the floor is rising or sinking, or you have water seepage, it’s best to call a professional to identify your issue before it gets worse.

Q: How do you waterproof basement floor cracks?

A: To begin with, it’s always smart to have a drainage system in place that can rid of unwanted water. There are ways to fill cracks in basements, but larger cracks may be a sign of larger issues, such as foundation failure.

Q: How big of a crack is dangerous in the foundation floor?

A: Generally, you don’t want cracks in the basement floor to be larger than ⅛”, and anything larger than ¼” is enough to warrant a call to the professionals. It’s better to be safe than sorry.
