Why Are Crawl Space Drainage Systems Needed?

A crawl space drainage system ensures that your home doesn’t end up with significant water underneath it. However, some people aren’t sure how water would even get in the crawl space in the first place, making it hard to see the use of crawl space drainage.

There are many potential inputs for water in your crawl space, but these are the most common.

Flooding from Outside and Inside

If you’re dealing with flooding, whether from a natural disaster, a structural issue, or an internal plumbing leak, it’s possible for that water to find its way into your home. It’s also definitely possible for it to come into your crawl space.

This is especially true if you have open crawl space vents or existing crawl space drainage solutions that just don’t work well enough. The incoming water can simply sit in your crawl space, leading to significant moisture and humidity.

When you have flooding issues, it’s important that you tackle the reason for that flooding in the first place. However, you also need to tackle the water it leaves behind, and a crawl space drainage system can do that. 

Hydrostatic Pressure

Hydrostatic pressure is the formal name for the pressure water exerts when it’s at rest. Because water is so heavy, it’s surprisingly powerful, and resting water can cause significant damage even if it’s not flooding over your home.

If you have too much hydrostatic pressure, you may see cracks in your home’s foundation or the floor of your basement or crawl space. That crack will then allow water to seep into the space.

It’s important that a crawl space drainage solution takes into account hydrostatic pressure. Typically, that means diverting it to another area so it doesn’t crack your home’s foundation or any other portion of your home. 

Unstable Planning and Building

The way your home is built will have serious repercussions for how it stands over the years. If you have an unstable plan or unstable building materials, that instability will stay with your home not only for the building phase but also while you live in it.

If your crawl space has a dirt floor, for example, it’s more likely to have issues with excess moisture. If it has open vents, it’s more likely to allow water in and make condensation worse.

There are many ways unstable planning and building can seriously damage your home, including how water is let in and out of your home. That’s why you need to invest in crawl space drainage solutions that fix those problems and offer solutions for them.
