How To Stop Crawlspace From Flooding During Rain Season – Guide

Crawlspaces can be overlooked in a home. They are often overlooked because you rarely, if ever, go in them. They are vital to the property’s functions and can cause serious problems if they become wet.

How does water get in my crawlspace after it rains?

Your problem is most likely that rainwater is accumulating in pools next to your foundation. Although the water may initially soak into the ground, eventually it will become saturated enough to pool above the ground. All that water must go somewhere. Only a small amount of the water will escape into the atmosphere. Rest of the water will seep through foundation walls and cracks in foundation walls, flooding your crawlspace.

How do I prevent a flood in my crawlspace?

You can also prevent basement flood . From a mitigation standpoint, both areas are very similar so you can do the same thing with a crawlspace to keep water out. Let’s look at some steps that you should take:

Keep water out of your foundation

Rainwater should flow away from your home by making sure that your gutters are working properly, that downspouts are correctly installed and that your lawn slopes away form your foundation. These are the most basic steps, but they are also some of the most crucial. Most crawlspace flooding problems start with groundwater pooling near your foundation, and eventually reaching the crawlspace. Watch your gutters and downspouts next time it rains. See how well they move water away from your home. If your gutters and downspouts are functioning properly but water is still pooling near your foundation, it could be an indication that your lawn slope is a problem. It’s sloped towards your home instead of away. These issues can be fixed and you’ll have solved most of your problems!

If all the above fails to make water disappear from your home, it may be time to do something more drastic: install a french drainage system. Although it is simple, this system can make a huge difference.

Install a Vapor Barrier

Vapor barriers are able to address any moisture problems your crawlspace might be having. Although it cannot stop a saturated crawlspace because of the issues we discussed above, it can be used in conjunction with other mitigation steps. It’s something that you can do with a little research and some elbow grease. You may want to hire a professional waterproofing company if you feel it is not something you can do.

Install a crawlspace sump-pump

Sump pumps can be used to prevent basement flooding. They also work well in crawlspaces. Sump pumps are devices that capture ground water and pump it out. These systems can be expensive so make sure they work when you call them to action. This means that you should always test the system to ensure it is working.

What do you do if water is in your crawlspace?

We recommend that you contact a water damage company immediately to assess the situation. Water damage is not something to be taken lightly.
