How Foundation Waterproofing at Peak Structural Works 

Depending on if your Colorado home is built on a crawl space or a basement, your inspector might suggest one of the solutions below, so you can stop living in fear of mother nature.

How Best to Waterproof a Basement or Crawl Space  

  • Interior Drainage Installation- Water will always find a way into your basement. By installing an interior drainage system, you can collect water from the walls and floor before damage is done. Our patented BasementGutter™ system is installed throughout the basement’s perimeter and typically connects to a sump pump. 
  • Sump Pump Installation- A reliable sump pump can keep your basement or crawl space dry permanently. Our basement interior drain system directs water toward the pump, where water is sent out and away from the home. To install a sump pump, experts must dig a pit or a dry well first, install the sump system, and then fit the pipes that will remove water from the home. In a crawl space, water is directed to the pump by the CrawlDrain™, which is also installed along the perimeter of the crawl space. 
  • Crawl Space Encapsulation- In addition to installing a crawlspace drainage system and sump pump, homes with crawl spaces typically need crawl space encapsulation to stay dry and healthy. A 20-mil thick, zero-perm liner is installed and sealed to walls and support posts to lock out moisture and water vapor.

Superior Foundation Waterproofing Products 

  • BasementGutter™– This revolutionary product’s anti-clog design collects water from the floor and the walls thanks to the built-in wall flange. Any water leaking will be directed into the system and pumped out, typically by a sump pump. 
  • Sump Pump- Our powerful lineup of sump pumps is designed and tested in the Front Range area’s tricky climate and unstable clay soils. Offering up to three pumps for ultimate protection and a sealed lid to lock out smells and pests, our sump pumps are a cut above the rest. 
  • Crawl Space Encapsulation- Sealing your crawl space off from water and moisture is key, but installing the right liner and insulation makes the difference. Peak Structural installs CrawlSeal™, a 20-mil thick liner that is mold, tear, and rip-resistant—drastically different than the 5-mil liner most hardware or big box store offers.

How Do I Know If I Need Foundation Waterproofing? 

Unfortunately, when it comes to foundation problems, homeowners typically notice the problem signs first before becoming aware of the problem. Read on to learn more about what to look out for.


Water leaking from your home’s foundation wall or floor is a clear sign you have a foundation problem that needs addressing. The sooner you do so, the better. Then, solutions can be less costly and time-consuming. It’s also a good idea to keep an eye on leaks from home plumbing, including water heaters and washing machines. Left untreated, all can cause foundation problems.

Tilting Walls

If you’re noticing your walls tilting, something is wrong with your foundation. Look for a permanent solution to both return your walls to their original position and stop any water intrusion. However, be sure the solution addresses the root cause and isn’t a bandage fix that will cause you to repair the problem repeatedly. 

Uneven Floors

Uneven or sloping floors in your home’s upper levels are a key sign of a problem below. And since your foundation is arguably the most critical part of your home—after all, everything else rests atop it—ensuring your foundation is level is of the utmost importance. The experts at Peak Structural can quickly and easily stabilize sinking and sagging floors with our customizable solutions.

It can be difficult to tell exactly where a leak is coming from. Identifying if a leak is coming from a plumbing or foundation problem typically involves investigating your home’s plumbing and looking for leaks. If you or a plumber do the repairs and you still see a wet or flooded basement or crawl space, it’s likely the problem lies with your foundation. The experts at Peak Structural offer free inspections to do this type of investigation for you. We understand just how tricky it is to find the source of a water leak and offer a free inspection for just this reason.

The short answer is yes. Even the smallest foundation leak can weaken your home’s foundation and attract pests since a dark, damp area is the perfect environment for insects to thrive. Mold caused by leaks can also pose health problems for your family, so being vigilant and acting fast is the best thing you can do.

Although plumbing leaks may be a cause, there are two main factors that contribute to foundation leaks—the clay bowl effect and hydrostatic pressure. The clay bowl effect is the process that occurs after your home has been built. Since a hole is dug for your foundation, loose backfill soil is used after construction. This loose soil is fluffier and creates an artificial water table around your home where water collects. 

Hydrostatic Pressure occurs when the soil around your home becomes saturated. Water is heavy, and the problematic clay soil in Grand Junction, Denver, and Colorado Springs soaks up the water and expands quickly, putting pressure on your foundation walls. This is known as hydrostatic pressure. 

As this pressure builds, basement walls begin to tilt inward, and cracks occur, allowing water to enter.
