If you’ve ever had a concrete slab in your backyard, you’ve also had to deal with standing water. The water looks unsightly, but it can also cause damage to your slab and create a breeding ground for mosquitoes.
This can be a major drainage issue and can cause a lot of damage to your property. This blog post will show you how to fix standing water on concrete slab using a few simple methods. Keep reading for more information!
Summary: There are a few different ways to fix standing water on concrete, depending on the severity of the issue. If the water is just a small puddle, you can use a plunger to push the water out and fix the hole with a sealant. If the water is deeper and has started to seep into the concrete, you will need to use a patch kit to repair the concrete. If the water is still present after using these methods, you may need to call a professional to fix the slab.
8 Common Reasons That Causes Standing Water on Concrete Slab
1. Water or Moisture Left on the concrete
Water or moisture can either be left on the concrete by accident or purposeful. If it is done on purpose, this will usually happen when a floor covering such as carpeting is installed and allowed to dry before installation thoroughly. The only way to verify if standing water is present after installation is to check for signs of mold growth and water penetration.
Water leaving the slab is called seepage and can be caused by many reasons such as porous soil, poor slope around the foundation perimeter, inadequate footing drains at the base of exterior walls or too small an area for proper drainage between footings. This water may not be visible immediately, usually pooling in the lower areas of the earth or confined to tight spots where water will have difficulty leaving the slab.
3. Plant Roots
Plant roots can cause water to pool on concrete slabs, and may also grow through cracks in the concrete, causing serious damage.
4. Drainage Pipe Blockages
This normally happens when a drain is clogged with debris, sand, or soil. This can be easily resolved by having the pipe cleaned out and inspected for the proper flow of stormwater away from your foundation. However, it may be necessary to have a new section of drainpipe added to the system in some cases. A good indication that this might be necessary is if you notice an increase in water pooling near your foundation after heavy rainfall.
5. Floor Was Installed in a Damp Area
If you’re adding a new room to your house and it’s below ground level, you need to be extra careful about moisture. Make sure to treat the concrete and seal it thoroughly before you install any flooring. Otherwise, you might end up with water on your floor.
6. Moisture Barrier on the Slab
A moisture barrier is a layer of material that is installed under concrete slabs. Its purpose is to prevent damage to the concrete and to help keep the area dry.
7. Sealing Over Failure
If there is standing water on your concrete slab after it has been sealed, it is probably because the sealer was applied over something that was not done correctly. If this happens, you should remove the sealant with mineral spirits and apply a new one that meets the manufacturer’s specifications.
8. Missing or Faulty Gasket
Another common problem is the lack of a gasket between the concrete slab and exterior door frame or brick molding. This can allow water to pool up on your floor even when it’s not raining outside. The only way to fix this type of thing is to install a new one. You might be able to do this yourself, but the entire process is rather involved and requires a lot of concrete work. You may want to call a professional or just leave it as-is and hope that water never gets in.
If you’re lucky enough to have a basement, there’s always the chance that it could leak. The most common cause of leaks in basements is cracks in the walls, but other causes include cracks in the floors and poor drainage around the outside of the home.
10 Easy Methods on How to Fix Standing Water on Concrete Slab
1. Using a Squeegee
A squeegee is a rubber blade attached to a long handle, which you move back and forth on the concrete slab. The rubber blades are available in various sizes and shapes. You can use them to flatten outstanding water or remove excess liquids from your concrete slab. Squeegees are inexpensive and easy-to-use tools that you can find at your local hardware store.
2. Using a Shop-Vac
A shop-vac is an inexpensive tool that can be used to remove standing water from the surface of your concrete slab. This process involves placing the shop-vac hose underneath the surface of your slab and then turning it on to suck out excess water. Using a shop-vac can help you save time and money since they are available at most home improvement stores and are very easy to use.
3. Allow the Concrete to Dry
If the water on your concrete slab is not yet dry, allow it to evaporate. Ensure there is enough ventilation around the area where you’re drying out your concrete slab before you continue any other kind of work for this method to be successful.
You can cover up your slab overnight with a tarp or plastic sheeting and then remove the coverings the following morning to allow it to dry. If you have a ceiling fan or another way of creating airflow in your garage, this will help expedite the drying process and get rid of standing water quickly.
4. Using a Blow Torch
Using a blow torch can effectively remove any excess water that remains on your concrete slab. If you do not have a blow torch, you can use a propane weed burner instead. This method is also effective for removing rust from metal surfaces around the garage.
5. Using Clean Concrete
Use clean concrete (not dirt or any other contaminate) to soak up excess water. Pour the clean concrete around your slab’s edges to help absorb any standing water that is present. Ensure that you cover up all bare spots or areas where there are no slabs before pouring in this material to avoid any damage to the soil underneath.
6. Using Clean Sand
Another method for removing standing water from your concrete slab is to use clean sand. Place the sand around the edge of your slab and let it sit there overnight. If you have a soil conditioner, mix it with the sand before applying this method to help break up any stains or discolorations on your garage floor.
7. Using an Absorbent Powder
Using an absorbent powder, such as baking soda, cornstarch, or talcum powder, can effectively rid your garage floor of excess moisture. Apply the powder directly to the water and let it sit overnight to work its magic. You can also mix some sawdust with these powders to help speed up the process and make it more effective.

8. Using a Floor Drain
If you have a floor drain in your garage, this could signify a problem with standing water on your concrete slab. If you do not know where this drain leads to, call a plumber immediately to come out and check the situation. If the drain is blocked, they will be able to unblock it and help get rid of any standing water present in your garage.
9. Using Sand to Remove Stains
You can also use sand to remove stains on your garage floor. Make a thick paste with the sand and hydrogen peroxide (do not mix too much of the paste or it will not be effective). Apply this paste directly to the stain and let it sit overnight once again. Removing the paste the following morning should reveal a stain-free concrete surface.
10. Improve the Drainage System
If you have standing water in your garage, there may be an issue with the way your drainage system is set up. To fix this problem, contact a landscaper or another type of service professional to see if they can figure out what’s causing the problem and how you can best resolve it.

Some Helpful Tips to Prevent Standing Water on Concrete Slab
- If you know the water will be hitting the concrete regularly (like in a kitchen), you can add a “drainage system” to get rid of that puddle of water.
- Make sure all joints and holes are patched up and filled in. Water has no place to go but stay on top of the flooring and cause problems.
- Make sure the ground is sloped away from your house. If you have a lot of water coming toward your house, screw some boards to stakes and angle them away from the foundation (if they aren’t already like that). This will make it more water runs down and away from the house instead of toward it.
- If standing water is due to a leak, you may want to get that fixed.
- Make sure your gutters are clean and covering the right things so the rain will run away from the house instead of toward it.
- If you live in an area that gets a lot of rain, you will need to take proactive measures to prevent flooding and standing water on a concrete slab.
Frequently Asked Questions
What Happens if Water Sits on Concrete?
Unfortunately, water sitting on concrete can cause a variety of problems. Firstly, it weakens the structure and causes it to deteriorate faster. This makes the concrete more likely to crack, shatter, or collapse during an earthquake. Additionally, if rain falls directly onto wetted surfaces such as tiles or bricks outdoor decks and walkways will become slippery which could lead to accidents.
In conclusion: If you see water dripping from your roof or walls make sure to contact a professional immediately in order for them to assess the situation and correct any issues as soon as possible!
Do You Keep Water From Standing on Concrete?
It depends on the type of concrete and the amount of water that’s present. Generally speaking, if the concrete is exposed to direct sunlight or rain, water will seep through and cause flooding. If the concrete is covered in a layer of gravel or crushed stone, water will not be able to penetrate and will slowly drain away.
Can Water Cause Concrete to Crack?
Anecdotal evidence suggests that water may weaken the bond between concrete and its underlying substrate. This can lead to cracks in the concrete surface. It’s important to note that this phenomenon is usually only seen with new or freshly poured concrete, and it subsides as the crate weathers and adjusts to its environment.
Does Water Weaken Concrete?
As the effects of water on concrete are highly variable. Some people believe that water can cause concrete to become brittle and susceptible to cracking, while others maintain that it has no significant impact on the material’s strength. In most cases, it is best to avoid water contact with concrete unless absolutely necessary.
The key to fixing standing water on a concrete slab is prevention. For example, if you’re an apartment building manager, be sure that the property has proper drainage and gutters in place, so there’s no pooling of rainwater around your buildings. For homeowners who have slabs outside their homes, make sure they are free from puddles by checking all downspouts and drains periodically or installing a gutter guard if needed.
It also helps store buckets or other waterproof containers near the door when it rains to capture any excess runoff before it can cause damage.
