Perforated Subsurface Drainage System

Definition

A perforated subsurface drainage system is a foundation drain consisting of gravel and PVC perforated pipe.

Purpose

This system is used to manage water flow and prevent water accumulation around building foundations. By allowing groundwater to enter the pipe through the perforations, it directs water away from the foundation, reducing hydrostatic pressure and preventing water damage.

Examples of Use

• Foundation Drainage: Installed around the perimeter of a building's foundation to prevent water accumulation and protect against water damage.
• Landscape Drainage: Used in gardens and landscaped areas to manage excess water and prevent soil erosion.
• Agricultural Fields: Implemented in fields to improve drainage and prevent waterlogging of crops.

Related Terms

• French Drain: A trench filled with gravel and a perforated pipe that redirects surface and groundwater away from an area.
• Drain Tile: A type of perforated pipe used for drainage systems in agricultural and residential settings.
• Sump Pump: A pump used to remove accumulated water from a sump basin, often found in basements.

Notes

• Installation: Proper grading and placement of gravel around the pipe are crucial for effective drainage.
• Maintenance: Regular inspection and cleaning may be necessary to prevent clogging and maintain performance.
