Drainage Panel

Definition

Prefabricated panels designed to facilitate the reduction of hydrostatic pressure.

Purpose

Drainage panels are used in construction to manage water flow and reduce the buildup of hydrostatic pressure behind walls and other structures. This helps prevent water infiltration, reduces the risk of structural damage, and enhances the longevity of the construction.

Examples of Use

1. Retaining Walls: Installed behind retaining walls to prevent water accumulation and relieve pressure on the structure.
2. Basement Walls: Used in basement waterproofing systems to channel water away from the foundation.
3. Green Roofs: Integrated into green roof systems to manage water drainage and prevent root damage.

Related Terms

• Weep Hole: An opening that allows water to drain out from behind a wall.
• Geotextile Fabric: A fabric used in drainage systems to filter soil and prevent clogging.
• French Drain: A trench filled with gravel or rock containing a perforated pipe to redirect surface and groundwater.

Notes

• Proper installation is essential to ensure the effectiveness of drainage panels.
• They are often used in conjunction with other waterproofing and drainage solutions.
