Underslab Drainage

Definition

Underslab drainage involves the continuous interception and removal of groundwater from beneath a concrete slab using perforated pipes.

Purpose

The purpose of underslab drainage is to manage groundwater effectively, preventing it from accumulating under the slab and causing structural issues, such as foundation movement or moisture problems.

Examples of Use

• Residential Homes: Installing underslab drainage in basements to prevent water ingress and dampness.
• Commercial Buildings: Managing groundwater beneath commercial structures to maintain structural integrity.
• Industrial Facilities: Ensuring dry conditions under factory floors where moisture could disrupt operations.

Related Terms

• Drain Tile: A system of perforated pipes used to manage water around foundations.
• Sump Pump: A device that removes accumulated water from a sump basin, often used with underslab drainage systems.
• Vapor Barrier: A material that prevents moisture from passing through walls, floors, and ceilings.

Notes

Regular maintenance of underslab drainage systems is necessary to ensure they function correctly. Blockages or damage to the pipes can lead to water accumulation and potential structural damage.
