Water Table

Definition

A Water Table is the level at which the pressure of water in the soil is equal to atmospheric pressure; effectively, the level to which groundwater will fill an excavation. It also refers to a projecting ledge or finish at the bottom of a building designed to carry water away from the foundation.

Purpose

The purpose of understanding the water table is to manage groundwater levels in construction and landscaping, ensuring proper drainage and preventing water-related issues in buildings. The water table ledge helps protect the foundation from water damage.

Examples of Use

• Construction Planning: Assessing the water table level to design proper drainage and foundation systems.
• Landscaping: Managing groundwater to prevent flooding and maintain healthy soil conditions.
• Building Design: Using water tables or ledges to direct water away from the foundation.

Related Terms

• Groundwater: Water present beneath the earth's surface.
• Drainage System: Systems designed to remove excess water from an area.
• Foundation: The base structure of a building that transfers loads to the ground.

Notes

Monitoring and managing the water table is crucial for preventing water infiltration and ensuring the stability of structures. Proper design features like water tables or ledges enhance building durability.
