Interior drainage systems Basics for Grand Rapids Properties

First, diagnose

For Grand Rapids homes below street level relative to the Grand River, interior drainage is often paired with a pump sized for real flood events, not just wet basements.

The full scope

• Perimeter drain paired with a properly sized sump
• Capacity for west-side slope runoff
• Compatibility with the existing foundation
• Discharge routed away from the Grand River grade
• Maintenance access planned in advance

Worth noting locally

Grand Rapids properties inside FEMA-mapped Special Flood Hazard Areas near the Grand River may face added review before new drainage work begins.
