Our Basement Waterproofing Process

1
Water Source Diagnosis

We determine whether water is entering through the floor, wall cracks, cove joint, or window wells — each requires a different approach.

2
Solution Design

A comprehensive waterproofing plan is developed — interior drainage, exterior excavation, crack injection, or a combination.

3
Installation

For interior drainage: perimeter drain tile is installed, sump pit is excavated, and a sump pump is installed. Crack injection fills structural cracks from the inside.

4
Grading & Drainage

Exterior drainage improvements — grading, downspout extensions, window well drains — are addressed to reduce water pressure against the foundation.

Frequently Asked Questions

What causes a basement to leak?
The most common causes: hydrostatic pressure from saturated soil, cracks in the foundation wall or floor, failed parging or waterproofing membrane, poor grading directing water toward the home, and clogged or inadequate drainage.
Interior vs. exterior waterproofing — which is better?
Exterior is the ideal solution but requires excavating around the entire foundation — expensive and disruptive. Interior drainage systems manage water that gets in and are more practical for most existing homes. The right answer depends on the specific water entry point.
How much does basement waterproofing cost?
Interior drainage systems run $5,000–$15,000. Exterior waterproofing with excavation is $20,000–$50,000+. Crack injection for single cracks runs $500–$3,000.
Will waterproofing allow me to finish my basement?
Yes. A properly waterproofed basement with humidity control is safe to finish with framing, insulation, and drywall. An active water problem must be fully resolved before finishing.
