If you have a wet crawl space, inadequate drainage might be the culprit. When water can’t drain properly, it will often accumulate in the same spot, causing mold, pests, musty smells, and other problems. Over time, excess water could affect your home’s structural stability, leading to expensive repair bills. 

Groundworks’ CrawlDrain™ system solves these issues. It prevents water blockages in your crawl space and ensures the smooth flow of water to a sump pump. Part of our crawl space drainage and encapsulation service, CrawlDrain™ keeps your home in Alberta dry and safe.

What Is Crawl Space Drainage?

Draining your crawl space means moving water from this part of your home to a sump pump, which stops excess moisture from damaging your property.  

CrawlDrain™ is a crawl space drainage system that consists of a 4-inch corrugated and perforated pipe wrapped in a silt sock. Acting as a filter, it ensures the smooth movement of water to a sump pump. We position CrawlDrain™ in a carefully excavated trench in your crawl space and surround it with gravel for ongoing protection. 

When used with other water management and crawl space encapsulation solutions, CrawlDrain™ controls moisture and protects your foundation.

Benefits of Crawl Space Drainage

When combined with other encapsulation methods, crawl space drainage offers these advantages:

  • Reducing excess moisture minimizes mold and musty smells, improving indoor air quality. 
  • An effective drainage system safeguards your foundation against moisture. 
  • Controlling excess moisture lowers humidity in your home and prevent your HVAC system from working too hard, reducing energy costs.

Cory came to my house, thoroughly evaluated the situation, explained the options to me, and patiently answered all of my questions. He is amazing. There was a crack in my basement wall that needed to be repaired. Paul (I think) did a good and clean Job. The repair was scheduled and completed exactly as was described to me. Great team! I’d definitely recommend this company to others.

Excellent service. Sales was pleasant and quote was thorough enough to proceed. The crew that came out to excavate, and install the interior and exterior basement systems was absolutely top notch – their work was neat and tidy, they showed up on time, and worked hard. To top it off, they (and all the folks involved) have to be the most pleasant contractors I’ve ever dealt with – and this is house #5 for us over the years! Thank you, Basement Authority. Highly recommend.

Yesterday we had our sump pump service by Ben and was very pleased with the work. He was knowledgeable and took care in his work. He was very friendly and explained what he was going to do. Very good at his job and we’ll ask for him if we need any work done in the future.
