Frequently Asked Questions

Foundation drainage can be installed either outside or inside, depending on site conditions, moisture levels, and the specific issue being addressed. Each option has its benefits, and in some cases, both systems are combined for maximum protection.

Exterior drainage:

• Installed around the foundation at the base of exterior walls.
• Includes a French drain (perforated pipe), filter gravel, and geotextile fabric.
• Captures water before it reaches the foundation wall.
• Recommended for new construction or major renovations.

Interior drainage:

• Installed along interior basement walls, beneath the concrete slab.
• Channels water to a sump pump system.
• Often used when exterior access is limited or not feasible.
• Effective for finished basements or targeted repairs.

The best choice depends on your property’s specific needs. To find the ideal drainage system for your home, contact Heneault Gosselin.
