Crawl Space Waterproofing Portland

Eliminate Hidden Leaks That Can Damage Your Portland Home

Water in your crawl space is never a good thing.

Crawl spaces (especially those with unfinished soil floors) don’t get much attention from homeowners. Many don’t even know crawl spaces need to be inspected for water damage.

Given how much it rains here in Portland, OR, this inattention can cause serious damage. Crawl spaces can become easy places for large and small leaks to “hide.” This could potentially lead to serious damage and an unhealthy environment in your home.

Without regular crawl space inspections in your Portland home, even small amounts of water can do serious damage.


How Does Water Enter A Crawl Space in Portland, OR?

Water enters and accumulates in your crawl space via:

  • Cracks in the foundation
  • Rusting metal from concrete form anchors
  • Cold joints where the vertical wall sits on the footer

Additionally, the soil floors found in many crawl spaces in Portland can let moisture seep in slowly over time.

Water Damage & Mold

Once moisture has accumulated in your crawl space, it can cause water damage to the structure of your house. Places it could damage include:

  • Foundation
  • Wood Beams
  • Floor Insulation
  • Heating Ducts

In addition, water and moisture can lead to the growth of hazardous mold. Once the relative humidity reaches 50% or higher, mold and mildew will grow. Since over half of the air you breathe in your home comes from the crawl space due to the “stack” effect, mold can be a major health hazard for you and your family.

In Portland, Oregon, mold is a very real and very serious problem.

But there’s good news: With regular inspections and a high-quality crawl space drainage system, you can keep water out of your crawl space.


Our Portland, OR Crawl Space Waterproofing Services

We recommend crawl space inspections about every 6 months in Portland. When inspecting your crawl space, we look for the following:

  • Visible mold growth
  • Discolored patches
  • Musty odors and mildew smells
  • Cracks and other visible structural damage
  • Standing water or accumulated moisture

If any of these are present, there is likely an issue with water entering your crawl space. If you do see signs of water damage or mold in your Portland home’s crawl space, the waterproofing experts at Rock Solid can help!

Installing a crawl space drainage system can help your crawl space remain clean, dry, and mold-free for years to come. At Rock Solid, we’re a team of experienced, full-service contractors. We can handle all the work ourselves (no subcontractors needed!), resulting in faster work and better results for you.


Our Trusted, Tested & Proven Crawl Space Drainage Systems

We have a proven system for keeping your crawl space dry. Our experienced crews will come to your Portland home and install our trusted crawl space drainage system.

In addition to just installing a sump basin, pump, and check valve, our proven system involves:

  1. Excavating and sloping trenches approximately 6″ to 12″ deep, allowing water to flow freely into the sump basin.
  2. Lining the trenches with 75-mil groundscape fabric, preventing clogging that might otherwise result from soil movement.
  3. Installing 3″ perforated PVC pipe in the trenches to drain water.
  4. Filling the trenches with 1” washed drain rock to help them maintain their shape and allow unrestricted water flow.

What Makes Our Crawl Space Drainage Systems the Best in Portland?

The difference is in the placement and construction of the drain pipe. Other companies may overlook the details that will make sure your crawl space drainage system actually works. Rock Solid focuses on the strength of the system, and its ability to withstand any rain storm thrown its way. We want your crawl space drainage system to be able to handle Portland’s harsh weather for years to come.

The drain pipes in our crawl space drainage systems are:

Completely Under the Soil

Draining moisture before the water can wick up through the dirt.

Positively Sloped To The Sump Basin

Ensuring active drainage, as opposed to a passive system that could fail.

Solidly Constructed & Installed

Unlike flexible corrugated pipe that could fail, our PVC drainage pipes maintain the shape of the slope.
