When Grand Rapids homeowners research basement waterproofing, they encounter two main approaches. Each addresses different problems at different costs.

Exterior Waterproofing

Excavates soil down to the footing, applies a waterproof membrane, installs new drainage board and drain tile, then backfills with gravel.

Cost: $10,000–$30,000+ | Disruption: Major — landscaping, driveways dug up.

Interior Waterproofing

Cuts a narrow channel at the basement floor perimeter, installs a drainage channel system directing water to a sump pit.

Cost: $5,000–$12,000 for most Grand Rapids homes | Disruption: Minimal — no landscaping disruption.

Which Is Right for Grand Rapids?

For the vast majority of West Michigan homeowners, interior waterproofing is the practical choice. Grand Rapids clay soil means water will continue pressing on your foundation even after exterior work. Modern interior drainage channels are essentially permanent.
