Critical Benefits of Sub-Soil Drainage Systems:
- Prevents basement leaks by carrying bulk liquid water away from foundation walls, footings, and floors
- Aids in minimizing water draw into concrete footings and capillary action into foundation walls
- Relieves hydrostatic pressure on foundation walls and minimizes risk of structural damage
- Increases the stability of foundations by preventing soil liquification under footings
- Helps manage humidity levels in finished basements by removing water against basement walls and floors
- Safer and healthier home due to fewer moisture problems, mold, and other adverse health outcomes
- Passively mitigates radon – creates low pressure path for radon gases to flow out and away from foundation
- Prevents soil erosion – creates pre-determined low resistive paths for water flow during large rain events
- Stops water from pooling on lawn surfaces thereby preventing soggy soil conditions
- Protects septic drain fields – underground curtain drains direct water around, and away from septic system
Underground Drainage – Did you Know:
Research by the United States Environmental Protection Agency (EPA) concluded 85 percent of surveyed buildings had been damaged by water, and at least 45 percent had experienced some leak within the building envelope. Water is a powerful damage function to materials and buildings, and is the second most reported insurance claim. Building materials subjected to continuous water exposure or repeated cycles can result in structural damage and rot. The health impacts of water and humidity problems can also be extensive. The U.S. Centers for Disease Control (CDC) finds the most common symptoms reported for people exposed to damp or wet buildings include, development or worsening of asthma, respiratory infections, bronchitis, eczema, and in severe cases developed hypersensitivity pneumonitis. The University of California (UC) at Berkeley estimates the health cost to building water problems and mold exposures at $3.5 billion dollars annually. The very first EPA recommendation to prevent moisture problems inside homes, is to control bulk liquid water, specifically to remove water away from building foundations. The CDC echo’s this recommendation by recommending fixing leaks through the homes building envelope, such as foundation cracks and holes, and using air-conditioners and dehumidifiers to keep indoor humidity levels between 30 to 50% year round.
The International Residential Code (IRC), section 405.1 requires a foundation drainage system anytime an underground basement encloses habitable or usable space. The Office of Energy Efficiency & Renewable Energy (EERE), provides guidance and best practices on the design and installation of sub-soil foundation drains, interior perimeter drains, and gutter drainage systems. Successful foundation drains systems provide pressure neutral open pathways for water to move by gravity. Most sub-soil drain systems use sloping perforated pipe bedded in clean rock, wrapped within a non-woven filter fabric. The geotextile ensures no fine soil material or sand percolate through the fabric, protecting the clean gravel and remaining open for air and water movement. Correctly oriented perforated pipe allows rising water to enter and move along the slope of the pipe, and out and way from the building footing and foundation walls.
