By the end of this page, you’ll see how our sump pump installation and crawl space encapsulation methods permanently resolve water concerns. 

Understanding the Crawl Space Sump Pump System 

A crawl space sump pump system is a vital tool in managing excess moisture and averting water damage in your home’s lower areas. It involves a submersible pump situated in the lowest part of a crawl space, housed within a sump pit or basin. 

Water from the internal drainage system flows into the sump basin. The pump, triggered by a float switch, activates when water accumulates in the basin. This system efficiently removes water from the crawl space, directing it through a discharge line, away from your property. 

Our AquaStop™ Crawl Space Sump Pump is a key element in a holistic moisture control strategy, which includes encapsulation, drainage, and dehumidification, ensuring a dry and healthy living environment. 

Installing this system not only resolves standing water issues but is also crucial for the air quality and structural health of your entire house. 

Indicators That You Need a Crawl Space Sump Pump 

Identifying the need for a crawl space sump pump system can prevent extensive damage. Watch for these telltale signs: 

Ignoring these signs of moisture problems can lead to severe and costly issues. 

Is it Necessary to Waterproof Your Crawl Space? 

Yes, equipping your crawl space with a dependable sump pump is crucial to avert further harm. 

Neglecting moisture signs in your crawl space can lead to escalating issues, requiring more extensive and costly repairs. DIY attempts or using generic products from retail stores often provide only temporary solutions. 

Timely intervention with Foundation Support Services’ AquaStop™ Crawl Space Sump Pump is essential. This system not only waterproofs but also strengthens your home against a variety of moisture-related problems, promoting a healthier, more robust home environment. 

Varieties of Crawl Space Sump Pumps 

Each home is unique, necessitating tailored sump pump systems for your crawl space. We offer three main options suited to a variety of homes: 

AquaStop Mini/Single Sump Pump System 

Our compact single sump pump system, with a small basin suitable for confined crawl spaces, utilizes a robust SafeDri™ cast iron pump for regular water removal. Typically, we install a SafeDri™ 1/3 hp pump, capable of processing over 2,000 gallons of water per hour. 

AquaStop Single with Battery Backup 

Our single sump pump system can be enhanced with a backup battery, ensuring continuous operation during power outages. This battery allows the system to pump out over 11,500 gallons per hour. 

AquaStop Triple Sump Pump System 

The AquaStop Triple Sump Pump System, our most robust offering, guarantees comprehensive protection. The primary SafeDri™ 1/3 hp pump manages everyday water removal. For larger volumes, a secondary SafeDri™ ½ hp pump, capable of over 3,000 gallons per hour, increases capacity. In power outages, a third, battery-backed pump ensures continued protection. 

Our skilled technicians will assess your crawl space’s moisture issues and recommend the best AquaStop™ sump pump system for your specific needs. Each of our pumps is designed to meet different requirements. 

Benefits of a Crawl Space Sump Pump 

Incorporating a sump pump into your repair strategy offers several benefits: 

  • Elimination of Standing Water: Sump pumps effectively remove all standing water, preventing further issues. 
  • Reduced Humidity and Mold Risk: A dry crawl space lowers humidity levels, significantly cutting down the risk of mold and musty odors. 
  • Improved Indoor Air Quality: A moisture-free crawl space doesn’t release humidity or spores into your living spaces. 
  • Enhanced Structural Integrity: Keeping the area beneath your home dry helps maintain its structural strength, averting expensive home damages. 
  • Increased Energy Efficiency: A dry and well-sealed crawl space blocks cold drafts and heat loss, improving energy efficiency and comfort in your home. 
  • Healthier Living Environment: A dry, structurally sound crawl space fosters a wholesome environment for your family. 

These advantages are maximized when using our specially designed AquaStop™ products, which outperform standard retail options in durability and effectiveness.
