Crawlspace Essentials


Crawlspace 101

Chances are you don’t spend a lot of time thinking about your crawlspace. Nobody’s blaming you—and honestly, who really considers their home’s crawlspace until there’s an issue? It’s recommended to inspect your crawlspace once every six months and look for leaks and signs of mold—among other red flags, but we’ll get to that later.

What is a crawlspace?

A crawlspace is formed from the structural components used to support a building—where there isn’t enough room to stand up—hence the “crawl.” It can be a very convenient way of reaching and repairing internal elements under your home such as plumbing and gas lines. Additionally, if you’re running out of storage room it can be an out-of-the-way place to keep holiday decorations and miscellaneous junk.

Common crawlspace calamities

Moisture is a crawlspace’s worst enemy. Some crawl spaces have unfinished, soil floors. These floors can allow moisture to seep in slowly. Water can also find its way in through cracks in the foundation, or through other porous materials above the crawl space -like drywall or wood. This water will lead to mold if left untreated, and this can be a major health hazard for you and your family. It’s easy to keep under control with a vigilant eye and help from professionals like us.

How often should I inspect my crawl space?

Get down on your hands and knees every six months to check for mold or leaks. Any issues should be fairly obvious. Visible mold or discoloration will be easy to spot. You may also notice a distinct musty or mildew smell. Beyond that, you should look for cracks and other possible paths of entry for water.

What’s the solution?

The good news is if you find a problem you can call in one of our professionals to help. Waterproofing is what we do and a crawl space drainage system can be a simple way to ensure that your crawl space will be clean and mold-free for years to come.

A crawl space drainage system consists of the following:

1. Excavate and slope trenches around the perimeter so water will flow freely to sump basin.

2. Install perforated pipe in trenches to drain water.

3. Fill trenches with drain rock to maintain trench shape and allow unrestricted water flow.

4. Line the trench with a Mira Drain and pour concrete over that.

5. Install sump basin, pump, check valve and discharge if gravity exit not possible.

The Basement Solutions Difference: We take the extra steps

1. The drainpipe is completely under the soil level so it will drain moisture before the water can wick up through the dirt.

2. The drainpipe is positively sloped to the sump basin ensuring active drainage vs. a more passive level system.

3. The drainage pipe is solid so it will maintain the slope vs. the flexible corrugated type of pipe.
