Understanding Foundation Drainage: A Solution to Hydrostatic Pressure and Groundwater Control

What is foundation drainage?

Foundation drainage is a system designed to manage and control the flow of water around and underneath a building's foundation. It prevents water from pooling around the foundation, which can lead to issues like soil erosion, foundation cracks, and moisture infiltration into basements or crawl spaces. The drainage system typically includes components like drains, pipes, and waterproofing materials to redirect water away from the foundation, ensuring the stability and longevity of the structure. 

 Moisture infiltration poses a significant challenge to below-grade foundations in buildings and homes. Factors like soil type, rainwater, groundwater, and improper grading contribute to damage, exacerbated by hydrostatic pressure.

Enkadrain 3611 offers a three-fold advantage by providing drainage, filtration, and protection.

What is Enkadrain 3611?

Enkadrain drainage composites serve as a lightweight alternative to traditional sand and aggregate drains. They are designed to relieve hydrostatic pressure from soils abutting below-grade structures and establish a consistent water path. Enkadrain's core function is to channel groundwater away from subsurface walls, safeguarding the structure from foundation cracking and interior moisture-related issues.

Key Features and Benefits:

  1. Effective Drainage: During construction, loose backfill soil can clog traditional aggregate drains. Enkadrain's geotextile filter fabric allows water to pass through while filtering out loose soil particles, preventing clogging and ensuring continuous drainage.

  2. Protection Layer: Enkadrain acts as a protective barrier, guarding the waterproofing membrane against damage from construction equipment, sharp rocks, or debris in the soil.

  3. Environmental Friendliness: Enkadrain drainage composites are environmentally friendly, comprising a post-industrial, recycled polypropylene core and geocomposite fabric bonded to one or two sides. These products contribute to LEED certification by offering recycled content, aligning with sustainable construction practices.


Enkadrain 3611 offers a comprehensive solution to foundation drainage challenges, addressing hydrostatic pressure and groundwater control effectively. By providing drainage, filtration, and protection, it ensures the durability and longevity of below-grade structures while promoting environmental sustainability through its recycled content. Incorporating Enkadrain into construction projects enhances both structural integrity and environmental responsibility, making it a valuable choice for builders and homeowners alike.
